M elissa’s lifelong fascination with snakes led her to work on a variety of projects on

natural history and conservation of reptiles in Arizona, California, and Mexico. The need for positive messaging about snakes became apparent as she saw firsthand how negative attitudes can stifle conservation efforts. She incorporated education and outreach into her research, and started blogging at SocialSnakes. org to foster appreciation for snakes by shar-

Reproduction of the Sagebrush Lizard, Sceloporus graciosus (Squamata: Phrynosomatidae) from New Mexico Stephen R. Goldberg, Whittier College, Department of Biology, Whittier, CA 90608; sgoldberg@whittier.edu

T he Sagebrush lizard, Sceloporus graciosus (Baird and Girard, 1852;

Figure 1) has a broad distribution ranging from Washington, Idaho, Montana and North Dakota, south to northern Baja California, northern Arizona, and northwestern New Mexico and as far east as western Nebraska (Ryan 2009).

measured 43 mm SVL and was considered to be a subadult. Female reproduction occurred from May to July (Table 2). There was no evidence that S. graciosus females produce a second clutch in the same year. This may reflect my sample of only nine gravid (enlarged ovarian follicles or oviductal eggs) females. In contrast (Goldberg 1975) reported 60% of S. graciosus females from California produced a second egg clutch. Neonates were collected from September. One with a SVL of 35 mm (LACM 4425) had presumably been born at least one month earlier. Goldberg (1975) reported neonates were observed from early August into late September in the San Gabriel Mountains, Los Angeles County, California. Fitch (1985) reported mean clutch sizes were smallest in four populations combined from the northwestern part of the S. graciosus range (3.3 Âą 0.51 SD, range = 2.7-3.9) and largest in the Wasatch Mountains of central Utah (6.03) and Greenhorn Mountains of the Sierra Nevada of California (6.30). In conclusion the timing of events in the reproductive cycle of S. graciosus in New Mexico is similar to other populations of this species. It follows the reproductive strategy adhered to by 91% of western North American lizards (Goldberg 2014) in which breeding occurs in spring, eggs are produced in late spring to summer. Young emerge in late summer and have time to feed and accumulate fat reserves before entering hibernation. Aknowledgementsâ&#x20AC;&#x201D;I thank Howard Snell, J.T.

Western Shovel-nosed Snake (Chionactis occipitalis) James C. Rorabaugh, P.O. Box 31, Saint David, Arizona 85630; jrorabaugh@hotmail.com

T he Western Shovel-nosed Snake (Chionactis occipitalis) was described by Edward Hallowell as Rhinostoma

occipitale in 1854. The type specimen, which is lost, was collected in 1853 by A. L. Heerman, a surgeon and naturalist, during the Pacific Railroad Expedition in the Mojave Desert of California, probably from the vicinity of the Mojave River in western San Bernardino County (Klauber 1951, Mahrdt et al. 2001). Cope (1860) was the first to use the genus name Chionactis for this species, although in subsequent publications it was at times assigned to Contia (Garman 1884) or Sonora (Slevin 1913, Stickel 1941). The Sonoran Shovelnosed Snake (Chionactis palarostris) was recognized as a species distinct from the Western Shovel-nosed Snake by Klauber (1937). Funk (1967) described C. saxatilis from the vicinity of Fortuna Mine in the Gila Mountains, Yuma County, Arizona, but the description was not widely accepted (Cross 1979, Mahrdt et al. 2001) and that taxon is considered synonymous with C. occipitalis by Crother (2012).

Four subspecies of the Western Shovel-nosed Snake are currently recognized (Crother 2012), including C. o. occipitalis, the Mohave Shovel-nosed Snake; C. o. annulata, the Colorado Desert Shovel-nosed Snake; C. o. talpina, the Nevada Shovel-nosed Snake; and C. o. klauberi, the Tucson Shovel-nosed Snake (Klauber 1951, Cross 1979). However, Marhdt et al. (2001) and other authors (e.g.,Wright and Wright 1957) have noted that these forms intergrade widely throughout the range of the species, and some populations are not diagnosable. Based on analysis of mitochondrial DNA and 14 morphological characters, Wood et al. (2008) found no evidence for four divisions within C. occipitalis. Rather, they identified two clades, one in the northwest and the other in the southeast portion of the speciesâ&#x20AC;&#x2122; range. The former includes specimens typically referred to C. o. talpina, C. o. occipitalis, and C. o. annulata. The southeastern clade includes C. o. klauberi and most of the range of C. o. annulata. The division between the two clades is roughly along the boundary between the Mojave and Sonoran deserts.

Description and Similar Species The Western Shovel-nosed Snake is small (< 432 mm total length (TL), the tail is 16-21% of TL) and strongly banded dorsally on the body and tail (Figs. 1, 2, and 3). The snout is yellow or cream-colored, sometimes mixed with red-orange or orange. Atop the head between and posterior to the eyes is a black crescent, the anterior edge of which is concave. Posterior to the black crescent are 17-40 black to brown bands on the body and 5-13 on the tail on a cream or yellow background. Between these dark bands are often red-orange to brown or black saddles. These saddles do not cross the venter, but at least some of the dark bands do. The color and the degree to which these saddles manifest vary by subspecies. The Mohave Shovel-nosed Snake has little or no evidence of saddles. Saddles are variably expressed in the Colorado Desert Shovel-nosed Snake (Figs. 1 and 2), but usually some orange or red-orange is present between the dark bands, and some specimens are strikingly tricolored. The Tucson Shovel-nosed Snake has red to orange-red saddles that are nearly always infused with dark markings. In the Nevada Shovel-nosed Snake, the primary bands are brown, and the saddles are orange-red, orange-brown, brown, or black (Stickel 1941, Klauber 1951, Mahrdt et al. 2001, Ernst and Ernst 2003). The snout is relatively long and the jaw is countersunk (Fig. 4). The rostral scale is broad and pointed posteriorly where it meets the suture between the two internasals, which are broadly in contact with each other. One loreal scale is usually present on each side. The smooth dorsal scales are arranged in 15 (rarely 14 or 16) rows at mid-body, and the anal plate and subcaudals are divided (Klauber 1951, Ernst and Ernst 2003). In our region, the Western Shovel-nosed Snake most closely resembles the Sonoran Shovel-nosed

The Western Shovel-nosed Snake is small (< 432 mm total length (TL), the tail is 1621% of TL) and strongly banded dorsally on the body and tail. The snout is yellow or cream-colored, sometimes mixed with red-orange or orange.

Snake, the Variable Sandsnake (Chilomeniscus stramineus), banded forms of the Western Groundsnake (Sonora semiannulata), and the Sonoran Coralsnake (Micruroides euryxanthus). The Sonoran Shovel-nosed Snake has a relatively wide black band or hood atop the head that is straight or nearly so anteriorly, rather than concave, it usually has fewer than 21 black dorsal bands on the body, 4-5 black dorsal bands on the tail, and has a relatively blunt snout. The Variable Sandsnake is comparatively stout, the rostral scale separates the internasals,

SONORAN HERPETOLOGIST 27 (2) 2014

and in the banded form that occurs in Arizona, the yellow, orange, or red-orange bands are in contact with the black bands. All bands on the Sonoran Coralsnake encircle the body, the snout is black, and the tail lacks red bands. In banded forms of the Western Groundsnake, the red or orange bands contact the black bands and a dark blotch is present on each scale in the lateral portions of the lighter bands. Distribution and Habitat Use The Western Shovel-nosed Snake occurs in the deserts of southeastern California, southern Nevada, and western Arizona in the U.S., and northeastern Baja California and northwestern Sonora in Mexico (Ernst and Ernst 2003). Of the four subspecies, Chionactis o. talpina is the northern-most, occurring in Inyo County, California and adjacent portions of Nevada. Chionactis o. occipitalis occurs south of talpina in the Mojave Desert of California, adjacent Nevada, and Arizona north of the Bill Williams River. Chionactis o. annulata occurs in the Sonoran Desert of southeastern California, southwestern Arizona, and south into northeastern Baja California probably to Puertocitos and in northwestern Sonora to the vicinity of Puerto Lobos. Chionactis o. klauberi occurs in the Sonoran Desert of central Pima, eastern Maricopa, and western Pinal counties (Mahrdt et al. 2001, Grismer 2002, Ernst and Ernst 2003). The range of the subspecies in Arizona and Sonora is illustrated in Fig. 5. Of Wood et al.’s (2008) two clades, only the southeastern clade occurs in Arizona and Sonora. At Organ Pipe Cactus National Monument, Rosen and Lowe (1996) found that Chionactis occipitalis was primarily a species of the valley bottoms and lower-most bajadas, whereas C. palarostris was more associated with the middle and upper bajadas. On the Sun Valley Parkway west of Phoenix, and Highway 238 through Mobile to the south of Phoenix, both of which traverse flats and lower bajadas, the Western Shovelnosed Snake accounted for 3.4 and 7.8%, respectively, of all snakes encountered during nighttime road riding (Jones et al. 2011). The Western Shovel-nosed Snake’s countersunk jaw, valves that close the nostrils to sand entry, and smooth scales lend themselves well to a life in sandy substrates (Mosauer 1935, Klauber 1951). The snake’s concave ventral surface may be an adaptation to facilitate efficient respiration while burrowing (Pough 1969). This species is commonly encountered in valleys with abundant windblown sand. In an area of sandy hummocks in the Coachella Valley, California, Cowles (1941) noted that of 96 reptiles excavated by land grading operations, 41 were Western Shovel-nosed Snakes. Rorabaugh (2002) observed 36 Western Shovel-nosed Snakes during 50.2 hours of walking surveys in sandy flats of the Yuma Desert, and based on an ad hoc mark and recapture effort suggested densities of this snake may approach that of some common desert lizards.

Although the Western Shovel-nosed Snake is common on low dunes and vegetated larger dunes, such as the Mohawk Dunes in Yuma County, it is likely scarce or absent in the interior of large, unvegetated dunes, like those found in the Gran Desierto de Altar, Sonora, and the Algodones Dunes in southeastern California. Although most commonly encountered in valleys, this species also occurs on dissected bajadas, and even penetrates into desert mountains along sandy arroyos where soils may be quite gravelly and coarse (pers. observations). A Western Shovel-nosed Snake was found crawling about on a rocky slope about 10 m above a sandy wash near Morongo Valley, California (Miller and Stebbins 1964). Funk (1967) found them in rocky areas with little sand in the Gila Mountains. Throughout its range, the Western Shovel-nosed Snake is a desert dweller, occurring from below sea level in portions of California to nearly 1500 m (Mahrdt et al. 2001). In the 100-Mile Circle, it occurs primarily in the Colorado Desert Subdivision of Sonoran desertscrub, but also sparingly into the Arizona Upland Subdivision. Elevational range in the Circle is about 325 m near the Gila River south of Phoenix to 700 m in the Waterman Mountains. Activity and Behavior

The Western Shovel-nosed Snake occurs in the deserts of southeastern California, southern Nevada, and western Arizona in the U.S., and northeastern Baja California and northwestern Sonora in Mexico.

Throughout its range, the Western Shovel-nosed Snake has been collected every month of the year; however, in the 100-Mile Circle, it has been found from March to early August, but most are encountered during April into early June. October, November, December, and February records exist for Yuma County and I have observed the distinctive tracks of this species (Fig. 6) near Puerto Peñasco and in the Gran Desierto de Altar, Sonora in mid-February. In Pima, Pinal, and Maricopa counties, the greatest number of collections has occurred in May (Rosen 2003). During the winter they have been found dormant in burrows or buried in loose sand at depths of 7.7-60 cm (Cowles 1941, Shaw 1953, Wright and Wright 1957). The Western Shovel-nosed Snake is primarily a nocturnal snake. Klauber (1951) found they are most

commonly encountered on roads from 1900 to 2200 h and when temperatures are 21 and 32°C. However, they are occasionally found on the surface in the morning and late afternoon (Klauber 1951, Brattstrom 1952, Warren 1953, Miller and Stebbins 1964). The 36 Western Shovel-nosed Snakes observed by Rorabaugh (2002) were all during daylight hours, from 0635 to 1215 and 1500 to 1930 h. Surface temperatures in the sun ranged from 24-46°C. Cowles and Bogert (1944) listed the minimum and maximum voluntary temperatures for this species as 20 and 31°C, respectively. These snakes are most commonly found on roads at night, but as mentioned, one can encounter them by walking through their habitat. During walking surveys on the eastern edge of the Algodones Dunes, Imperial County, California, I have observed up to seven of these snakes during a three hour period after sunset. Twelve were found at night during two hours while walking with a Coleman lantern in the Coachella Valley (Warren 1953). Following their distinctive serpentine tracks (Fig. 5) across loose sand sometimes results in a capture (Warren 1953, pers. observations). They also are readily captured in pitfall traps (pers. observations), and are occasionally found under boards or other surface debris during the day (Cunningham 1966). Funk (1967) found Western Shovel-nosed Snakes in the Gila Mountains by turning rocks. Through undulatory movements, this species can quickly “swim” into loose sand, almost as easily and rapidly as it moves about on the surface (Klauber 1951). It spends most of the daylight hours underground in rodent or scorpion burrows, under surface debris, or simply buried in loose sand (Klauber 1951, Miller and Stebbins 1964). The end of the tail of buried snakes may be exposed on the surface (Warren 1953, Norris and Kavanau 1966). Surface active snakes can move quite rapidly, and as with other tricolored banded snakes, the banding pattern appears to blur during rapid movement. If confronted by a human or predator, this snake typically flees from the threat at high speed. However, if cornered, it may coil and strike repeatedly, usually with the mouth closed. Warren (1953) found that some Western Shovel-nosed Snakes pursued in the field climbed short distances up into creosote bushes (Larrea tridentata). Captured Western Shovel-nosed Snakes will usually smear their captors with musk and feces (Ernst and Ernst 2003). During a photo shoot that required repeated repositioning of the snake, Mitchell (1978) observed a captive that rolled into a tight ball with its head hidden amidst its coils. Klauber (1951) reported that Western Shovel-nosed Snakes were preyed upon by a domestic cat and a Coachwhip (Coluber flagellum). Mahrdt and Banta (1996) found two Western Shovel-nosed Snakes impaled on an ocotillo (Fouquieria splendens), apparently by a Loggerhead Shrike (Lanius ludovicianus), in the Yuha Desert of Imperial County, California. In 1978, I also ob-

served a Western Shovel-nosed Snake impaled, almost certainly by a Loggerhead Shrike, on a desert willow (Chilopsis linearis) in Bow Willow Canyon, eastern San Diego County, California. C. H. Lowe found remnants of a Western Shovel-nosed Snake in a Great Horned Owl (Bubo virginianus) pellet at the Mohawk Dunes (Mahrdt et al. 2001). The smallest mature male reported was 194 mm SVL (Goldberg 1997). Ernst and Ernst (2003) surmised that most individuals mature at 250-260 mm TL. Mating behavior has been observed in the wild in late May (Klauber 1951). Clutches of usually 2-4 eggs (6 was noted by Funk [1967], and Cowles [1941] noted 6 and 9 ova in two females) are laid primarily from May into July (Mattison 1989, Golberg 1997, Goldberg and Rosen 1999); however, Funk (1967) reported three captive females from the Gila Mountains that laid eggs in late March. Those eggs hatched 94-99 days later. Hatching probably occurs from June into September. Hatchlings resemble adults but are 112-124 mm TL (Klauber 1951, Wright and Wright 1957, Funk 1967). On 10 May, Goode and Schuett (1994) observed combat between two adult, captive males captured the previous month at the Mohawk Dunes. The snakes intertwined and writhed under the sand for less than a minute. In a subsequent encounter, short bouts (less than 30 seconds) of biting and entwining occurred.

Through undulatory movements, this species can quickly “swim” into loose sand, almost as easily and rapidly as it moves about on the surface.

One male was also observed to vibrate its tail when the other approached. Diet This small snake is almost certainly an active forager, seeking prey on the surface and perhaps below ground, as well. Scorpions, centipedes, an egg from a Common Side-blotched Lizard (Uta stansburiana), spiders, moth or butterfly pupa, beetles and their larvae, various insect parts, and unidentified pupa have been found in the stomachs of Western Shovel-nosed Snakes (Klauber 1951, Rosen et al. 1996, see review in Ernst and Ernst 2003). I observed a Western Shovelnosed Snake eating a small scorpion (probably Paruroctonus or Smeringurus) at night in an area of windblown sand in the Mohawk Dunes. Captives have consumed moths, crickets, grasshoppers, silverfish, earwigs, cockroaches, termites, spiders—including black widows, mealworm larvae and pupa, waxworm larvae, various other insects, scorpions, centipedes, solpugids, a hatchling Common Side-blotched Lizard, and the tail from a hatchling Tiger Whiptail (Aspidoscelis tigris; Klauber 1951, Stebbins 1954, Cunningham 1959, Norris and Kavanau 1966, Funk 1967, Glass 1972, Mattison 1989, Rosen et al. 1996). These snakes are adept at capturing and eating scorpions. They are sometimes stung in the process, but do not show any apparent ill effects (Norris and Kavanau 1966, Glass 1972). Western Shovel-nosed Snakes will often hold larger prey down with a loop of the body, although captive snakes did not employ this strategy with scorpions (Glass 1972). Three moderately enlarged, grooved teeth are present on each side in the rear of the upper jaw (Wright and Wright 1957) that may be used to deliver salivary toxins to prey. Conservation

the species, habitat loss is relatively small and localized. The Western Shovel-nosed Snake is listed as a species of least concern on the IUCN’s 2013 Red List. With a valid Arizona hunting license, four may be collected per year or held in possession alive or dead, except that take of these snakes is prohibited without special authorization in protected areas, such as National Wildlife Refuges and National Park Service lands. On 15 December 2004, the Center for Biological Diversity (2004) petitioned the U.S. Fish and Wildlife Service (USFWS) to list the Tucson Shovel-nosed Snake as endangered with critical habitat under the Endangered Species Act. In a Federal Register notice dated 31 March 2010, USFWS found that the Tucson Shovel-nosed Snake (excluding intergrade populations) warranted listing but was precluded by higher priority listing actions (USFWS 2010). Nonetheless, the warranted finding adds the Tucson Shovel-nosed Snake to the list of candidate species and commits USFWS to publishing a rule proposing the subspecies as threatened or endangered, possibly with critical habitat, barring new information that such a rule is unnecessary. The primary basis for the warranted finding is that as of 2001, over one-third of the area within the range of the Tucson Shovel-nosed Snake had been converted to urban or agricultural development, and that anticipated future development and habitat degradation is likely to increase that percentage substantially unless protective measures are taken (USFWS 2010). The last Tucson Shovel-nosed Snake seen in Pima County was in the Avra Valley in 1979 (Rosen 2003). Recent surveys indicate populations persist in areas dominated by creosote flats along State Route 79 between Florence and Highway 60, along the Maricopa Road between Maricopa and Gila Bend, east of the San Tan Mountains, along State Route 349 between Maricopa and Casa Grande, south of Interstate 8 near the northern boundary of the Tohono O’odham Na-

Most of the urban and agricultural development in the desert Southwest occurs in valleys, and as the Western Shovelnosed Snake is primarily a denizen of valleys, it is not surprising that habitat loss has occurred in many areas, particularly in the Coachella, Imperial, and Borrego valleys of California; the Mexicali and Río Colorado valleys in Mexico; the Yuma Valley and Mesa; the Gila River Valley; and in the Phoenix metropolitan area and Interstate 10 Tucson-Phoenix corridor in Arizona. Nonetheless, over the entire range of Figure 6. Serpentine tracks of the Western Shovel-nosed Snake, Pinta Sands, Yuma County.

tion, in the vicinity of the Santa Cruz Flats near Eloy and Picacho, and potentially in the Rainbow Valley and portions of Vekol Wash (Rosen 2003, 2007; Mixen and Lowery 2008; USFWS 2010). USFWS’s 2010 finding downplays Wood et al.’s (2008) work by saying that the “study’s inference was based on a single genetic marker of mitochondrial DNA and did not include examination of nuclear markers, which would more fully elucidate our understanding of the taxonomic standing of this subspecies.” In the latest version of the Society for the Study of Amphibians and Reptiles (SSAR) list of amphibians and reptiles of North America (Crother 2012), the four subspecies of Chionactis, including the Tucson Shovel-nosed Snake, are still recognized. However, if the conclusions of Wood et al. (2008) are subsequently accepted, and the Tucson Shovel-nosed Snake is no longer recognized as a valid taxon, USFWS may be hard-pressed to identify a listable entity within Chionactis that meets the definition of a threatened or endangered “species” under sections 3 and 4 of the Endangered Species Act, even though the 2010 finding and the 2004 petition make a strong case that Western Shovel-nosed Snakes in the Tucson to Phoenix area are substantially threatened with habitat loss and degradation.

Village ponds are good reservoirs for fresh water turtles. Twenty-seven turtle species occur in India. Each state in the country holds at least one species of turtle with a maximum number of 17 turtle species occuring in the state of West Bengal (77.3%). West Bengal, with its huge biodiversity, has been one of the targets of wildlife trade in India. It is a major hub for turtle and bird trade. Bordering three countries— Bangladesh, Bhutan and Nepal—it acts as a central transport point for wildlife smuggling from India. From West Bengal turtles are often smuggled to countries like Thailand and Malaysia through a sea route. Four species of marine turtles—Olive Ridley Sea Turtles (Lepidochelys olivacea), Green Sea Turtles (Chelonia mydas), Hawksbill Sea Turtles (Eretmochelys imbricata), and Loggerhead Sea Turtles (Caretta caretta)— have been reported from the West Bengal coast. Present records indicate that the Olive Ridley Sea Turtle is the most widespread and abundant marine turtle along this coast and is reported to visit Junput sand bar, Digha, Nayachar, Shankarpur, and the sea-facing islands of the Sunderbans. River turtles and their eggs are an important commercial product in many regions throughout the globe. Turtles are collected from Punjab, Jammu, Orissa, and Andhra Pradesh and transport along with fish for trade in different parts of West Bengal. Turtle meat is particularly popular among the people in West Bengal. The findings in Hanfee (1995) show that tribes and castes from riversides are known to exploit turtles for meat and carapaces. The original trade value is very tricky to assume because of the lack of adequate data in West Bengal. The illegal trade of freshwater domestic turtles has escalated to meet international demands, moving through Bihar and Kolkata to Bangladesh, and from there to southeast Asia. Besides their involvement in the pet trade, turtles and tortoises are traded for meat, medicines, and their carapaces. Turtle meat varies depending on the type of turtle and the part of the turtle being consumed, tasting similar to turkey or fish. Turtle soup is made from the flesh of the turtle. The soup is prevalent in some cultures and is viewed as a luxury (turtle soup is recommended by alternative medicinal practitioners like Sheng-Nong (Shen-Nong.com, an online Chinese Medicine guide) for menopausal symptoms such as night sweats, hot flashes, and irritability). The Green Sea Turtle was commonly used for turtle soup in the United States. Turtle soup was U.S . President William Howard Taft’s favorite food. A cup of cooked soft shell turtle meat has about 220 calories and 9 gm of fat. In addition to being a good source of protein, soft-shelled turtles are high in calcium, with vitamins A (2%), B1, B2, and B6 and phosphorous and zinc. There are 89 calories in a turtle leg serving of turtle meat (Total fat 0.5 g, cholesterol 50 mg, potassium 230 mg, sodium 68 mg, total carbo-

hydrate 0 mg, protein 20 mg). Although turtle protection laws exist, they are sometimes weak, under-regulated, or more significantly, not well enforced. As members of CITES (the Convention on International Trade in Endangered Species of Wild Fauna and Flora), many countries have agreed to safeguard wild species from international trade. In spite of laws of shielding sea turtles in most countries, the illegal trade of eggs, meat, and shells of turtles continues to be a threat. In different parts of the world, these animals are collected for their meat and eggs which are used for human consumption. In many countries, the trade in turtle eggs is so large that it provides a significant income to many people. In September 2013 the Border Security Force of India (BSF) seized 952 Indian Star Tortoises (Geochelone elegans; 7 days to 7 years old) packed in burlap bags and worth 31.9 million rupees (Rs) that were being smuggled to Bangladesh from near the Tentulberia Border Outpost in West Bengal. In November 2013 again BSF seized 40 million Rs worth of star tortoises; and the Bidhanagar police arrested three people and seized 70 sacks of turtles and star tortoises. Flapshell Turtles (Lissemys punctata) are also smuggled from Uttar Pradesh to West Bengal and out of India. Women from South and North 24 Parganas are involved in smuggling the turtles bought for 2,000 Rs per kg from Etawah, Oriah, Manpura, Sikurabad, Farukabad and Jaunpur districts of Uttar Pradesh and sold for 10,000 Rs per kg. The first such arrest of seven women was made at Kanpur Central station when on a tip-off the Railway Protection Force found 400 live turtles. The current rate of totally unsustainable consumption of turtles and tortoises in India could lead to

rapid extinction of several species. Conservation and protection of turtle from anthropogenic pressure is the toughest task. Training in-country students and supporting personnel is essential to encourage younger generations all over the world to become passionate about biodiversity, mostly their local biodiversity. Workshops should be organized for students and young researchers. Publication of field guides in local languages for local people and students is needed. The sign boards displayed by the West Bengal Forest Department prohibiting trade of turtles and turtle

products mention the protection of marine species only. There is a serious need for a critical assessment of the population structure and habitat of the species of freshwater turtles to see whether any species needing protection have been left out.

Key paper published on the Diversity and Conservation of Amphibians in South and Southeast Asia Suman Pratihar, Department of Science and Technology, New Delhi, India, Vidyasagar University; pratihar_vu@rediffmail.com Howard O.

A total of 19,232 species were discovered as new to science in the year 2009. The majority these were

plants and insects, but amongst the remaining species, 148 were amphibians (Hance 2012). Despite a global decline in the number of amphibians over the past 25 years, the number of species has skyrocketed. David Wake, a biology professor at the University of California, described the 7,000th amphibian taxon in July of 2012 according to the catalogue maintained by Frost (2013), a project which since 2000 has been striving to document every extant amphibian taxon on earth. The ‘new’ species total of about 3000 means that scientists have defined a previously unknown amphibian every two and a half days since 1987. Nevertheless, about 41 percent of amphibian species are at risk of extinction, according to an assessment by the International Union for the Conservation of Nature and Natural Resources (IUCN) in June of 2012. Some of them are already extinct. Over the past few years, 50 new species of amphibians were discovered in Sri Lanka alone (Pethiyagoda and Manamendra-Arachchi 1998). In recent times, Brazil, Peru, India, and China have taken the lead in claiming the most new species. Three new species were being discovered per week, and a total of about 100 new species were described in 2012. Most of the new species, however, have yet to be carefully evaluated. They are poorly known, often only from a single population, and many are from areas with limited habitats that are under intense pressure due to land conversion and other factors. 2013 was a dynamic year for amphibians and Frost (2013) added 146 new taxa, 944 new photos, 30 new call recordings, and 62 new species accounts. The current number of amphibian species is 7,215 as of 22 December 2013 (Frost 2013). Pratihar et al. (2014) discuss the diversity and conservation of amphibians in South and Southeast Asia. They have documented the updated and available information (also included is a checklist with the red list statuses of amphibians in this region) on the diversity of amphibians in South and Southeast Asia and China.

Water, water everywhere and not a drop to drink: Dehydration in Sea Snakes Summary By Dave Bertelsen, member, Tucson Herpetological Society

C onventional wisdom tells us that creatures living in the ocean derive the water they need from the sea

with the help of organs such as salt glands or through processes such as osmosis. Convention wisdom is often wrong, as shown by several species of sea snakes, including Hydrophis platurus, yellow-belly (pelagic) sea snake, widely distributed in the Indian and Pacific Oceans. Lillywhite et al. (2014) studied 500 Hydrophis platurus individuals captured off the coast of Costa Rica and found they require fresh water, most likely obtained from freshwater lenses forming on the ocean surface during heavy precipitation. Since precipitation usually falls over land, however, the ocean can be a veritable desert in the dry season. As a result Hydrophis dehydrates during such periods and may remain in a dehydrated state for over six months. Total body water content in hydrated snakes was about 80% and in dehydrated individuals, about 74%. (This compares to approximately 68-77% in freshwater snakes.) Snakes captured at the end of the dry season had significantly lower total body water. Those drinking freshwater after capture had a significantly lower body condition index (BCI); the amount of water they drank varied inversely with BCI. The authors suggest the snakes have a dehydration threshold above which fresh water is needed to maintain body condition.

In a recent article for Natural History, Lillywhite (no date) describes his long interest in sea snakes and their need for fresh water. He notes that four of five distinct lineages of sea snakes are known to require fresh water (the fifth lineage is not well-studied), including such species as Marine File Snakes (Acrochordus granulatus), Yellow-lipped Sea Kraits (Laticauda colubrina), and Blue-banded Sea Kraits (L. laticaudata). Perhaps we need to reconsider, as Lillywhite suggests, the conventional wisdom that sea turtles need only sea water since they can excrete excess salt from their salt glands.

Conventional wisdom tells us that creatures living in the ocean derive the water they need from the sea with the help of organs such as salt glands or through processes such as osmosis. Convention wisdom is often wrong, as shown by several species of sea snakes, including Hydrophis platurus.

term “author(s)” is in reference to the authors of the work being reviewed (op. cit.). The paragraphs preceding the section “Turtles in Sonora,” represent reviews of the respective chapters in the first major (introductory) section of the book, and a general review of the second major section of the book (the descriptions of families, genera, and species). The sections are headed in bold, while the paragraphs open with the titles of their representative chapters in italics. The section “Turtles in Sonora” reviews the eleven native turtle species occurring in Sonora related to specific points in the book, or those not mentioned. It follows the taxonomic order of the descriptive accounts. Turtles: A Paradigm of Variability, Venerability, and Vulnerability

Introduction includes the objective: to be a reference (vade mecum) rather than a cover-to-cover read and intended “for those who will study and learn new things about Mexican turtles and turtles in general.” The authors hope “the book will also foster communication among persons who study turtles as a hobby and those who consider it a profession.” The general defining feature of the book is the morphologic identification keys intended for whole specimens, and a collection of natural history and distributional information. With regard to recent taxonomic work, taxonomy and nomenclature is conservative. Also included here is: a history of turtle study in México; previous books on turtles including the only other treatment of Mexican turtles by Smith and Smith [1979]; definition, origin, and phylogeny of turtles, although it does not include the recent discovery of Eunotosaurus which pre-dates Proganochelys by 40 to 50 million years as the possible earliest ancestor to chelonians; classification used in the book; biogeography, climate, and topography; and Cenozoic paleogeography (the most recent 65 million years, involving various connections and disconnections between North and South America, which was integral in the formation of the biota of the New World tropics). Materials and Methods Used for This Book defines the their terminology, acronyms, abbreviations, and description of species geographic ranges/maps. Structure and Function describes the skeleton, vital organs and systems, senses, locomotion. One learns about the many things that make turtles physiologically unique beyond the well known shell-as-fortified external ribcage. Here are some highlights. Integument covers barbels (pimple-like elements) on the skin of aquatic turtles sensitive to external stimulus like water flow changes potentially indicative of prey, predators, mates, etc; and musk glands that produce predator repellants, and territorial and mating pheromones. Periodic Plastral Kinesis and Large Eggs documents the dilation of the posterior shell and pelvic opening for passage of large eggs, including fibrous connective tissue but-

tressing the plastron that allows for this. In Circulatory System one learns of the cardiopulmonary benefits to turtles via an “imperfectly” four-chambered heart that are not possible in birds and mammals: during a dive when the lungs are not in use, turtles are able to economize the use of oxygenated blood (from their last breath) by partially bypassing the pulmonary circuit. In Respiration one learns of other adaptations that augment aquatic life: by pumping water over highly vascularized regions in the cloaca, gut, and the mouth cavity, turtles can capture the dissolved oxygen in water. Most impressive is The Chelonian Ear and Vocalization. The first author has pioneered new research in this area. Until recently turtles were thought to have “poor” hearing and that only males vocalized during mating. Other sounds were thought to be involuntary via exhalations. It is now known that turtles have a wide repertoire of vocalizations. The authors present anecdotal and documented super- and subsonic communication in North American freshwater turtles, Australasian snake-necked turtles, and South American river turtles. Most compelling is the documentation of sounds made by Podocnemis expansa, seemingly to maintain groups (alerting each other, synchronized nesting/nest emergence). Emerging/surfacing hatchlings increase vocalization during migration to the water from their nest to expectant mothers (also vocalizing). Mothers and hatchlings are observed surfacing and vocalizing together. Natural History covers reproduction, eggs, temperature-dependent sex determination, hatchlings, ontogeny, sexual dimorphism, ecology, shell algae and iron deposits, growth rings, and longevity. Most fascinating would be plasticity of growth reflected in growth rings and lack thereof in old specimens; the ability of females to store sperm up to at least 4 years from mating with a male (Terrapene sp.) and produce fertile eggs, and the algae Basicladia which almost exclusively grows on the carapace of turtles and is able to survive long periods of desiccation. Turtles, Humans, and Research describes the exploitation of turtles in industrialized Mexico, including turtle farms intended to mitigate the harvest of wild turtles; Mexican laws and the general permitting process needed to work with turtles; and the Comparative Quality of Turtle Flesh describing the preparation and taste of freshwater turtle meat in Mexico. A short review or commentary of turtles in the pre-Columbian world with iconography would have been nice since they played some part in the food and culture of the first American peoples and ergo some species were/likely were distributed in this manner (Mills 1970). Field and Laboratory Techniques is a “how to” on standard measurements, terms, and nomenclature; capture methods (including the aid of dogs); stomach flushing for dietary analysis; egg incubation; dissection; and museum preparation of turtles. Radio-telemetry is not discussed, however the authors must assume the read

“For those who will study and learn new things about Mexican turtles and turtles in general.” The authors hope “the book will also foster communication among persons who study turtles as a hobby and those who consider it a profession.”

er/researcher can defer to other specific works. Modern Taxonomic Studies and Techniques lists the attributes of morphological and phylogenetic taxonomies of turtles, and advocates for the use of both techniques using carefully chosen traits to support each method. Ergo the gross taxonomy of turtles used is the authors’ interpretation and at odds with a recent turtle phylogeny (Spinks and Schaffer 2013). Accounts of Taxonomic Groups

This is the bulk of the book. Minor breaks/inconsistencies in font size and bolding made it difficult to find taxa by paging through the taxonomic sectioning without consulting the pagination at the head of each family/chapter. One of the surprising observations, however is that the monotypic Central American River Turtle, American Mud Turtles and Musk Turtles, and North American Softshell Turtles are placed under the superfamily Trionychoidea (Softshell Turtles). Taxonomic historical prologues where applicable, etymologies, and common names make reading especially enjoyable. Common names generally follow the ones encountered by the authors’ work, and other authors where applicable. With the exception of the monotypic Dermatemys mawi, species keys are composed by their respective family and found in the introduction to each family/chapter. Species accounts are divided by their respective species groups where applicable, and usually listed alphabetically. Turtles in Sonora Superfamily Trionychoidea: Family Kinosernidae: Subfamily Kinoserninae (Mud and Musk Turtles)

Some interesting traits occur in this group. A clawlike scale tipping the tail is present and generally pronounced in males, aiding insertion during coitus. Kinosternids also produce sounds in three ways. The first is perhaps an artifact of the “clasping organs”: patches of rough, keratinized skin on the posterior of the thigh and calf, highly developed in males, that facilitate grasping the female and sometimes results in sound production during mating. These clasping organs are absent in the Kinosternon scorpioides species group. The last two sounds are produced when the turtle is frightened or upset, either by an exhalation (grunt or squeak), or by the grating of the mandible against the maxilla. While some species are more adapted to permanent water than others, all have the ability to withstand periods of dryness by burying themselves until a suitable body of water is found or replenished (aestivation). Sonoran Kinosternon are largely diurnal, however many species can be crepuscular with the onset of rain. Kinosternon flavescens Species Group (Yellow Mud Turtle)

The authors treat K. arizonense, K. flavescens, K. durangoense, K. bauri, and K. subrubrum as a group based on

Iverson (1998; the former two occur in Sonora, the latter two don’t occur in Mexico). Thyrosternon is a generic name previously used by Agassiz (1857), available for the group should someone propose it, further supporting the monophyly of the group. Recently Iverson et al. (2013) further supports it, albeit referred to as the “subrubrum group”. Of the four Sonoran Kinosternon, the most distinct are K. arizonense and K. flavescens. They have a generally round, broad carapace, lighter dorsal coloration, unmottled face, and yellow or cream colored lateral and ventral region of the face and neck. They are closely allopatric, being separated by the San Pedro where distributions come closest to meeting on the US-México border. K. arizonense is found in much of Sonora, while K. flavescens enters extreme northeastern Sonora in the Sierra San Luis (Minkcley, field notes 2012) from Chihuahuan desert/grassland corridors. K. flavescens is known to brumate with other species of turtles (Carpenter 1957 in work reviewed). While chiefly restricted to permanent water, terrestrial mating has been observed in K. flavescens (the authors). K. hirtipes Species Group (Rough-footed Mud Turtle)

Comprised of K. hirtipes, and K. sonoriense, only the latter (including both of its described subspecies) is found in Sonora. The authors postulate K. sonoriense speciated from hirtipes during the formation of the Sonoran and Chihuahuan deserts with which they are respectively associated (the authors), however both may be found in oak woodland which could mean the possibility of K. hirtipes in extreme northeastern Sonora via oak woodland corridors. Their genetic relatedness is supported recently by Iverson et al. (2013). K. sonoriense can be sympatric with the rest of its congeners in Sonora, albeit tenuously with K. alamosae and K. integrum. Its distinguishing features are the weakly formed lateral lines within the mottling of the head, and the presence of clasping organs. Much research has been conducted on K. sonoriense, and the subspecies K. s. longifemorale is restricted to a small area on the Arizona-Sonora border. While chiefly restricted to permanent water, Stone (2006) notes “terrestrial flight” behavior occurring ~30 minutes after hand capture wherein the turtle crawls up the nearest, steepest slope. The authors cite the International Union for the Conservation of Nature’s 2006 rating of “Vulnerable” for K. sonoriense due to the consumption of limited water resources. However, K. sonoriense is now listed in the preceding, less sensitive category “Near Threatened” (van Dijk 2011).

Accounts of taxonomic groups: this is the bulk of the book. Taxonomic historical prologues where applicable, etymologies, and common names make reading especially enjoyable.

K. scorpioides Species Group (Scorpion or Redcheeked Mud Turtle)

This group is found in most of tropical Mexico and comprises K. acutum, K. alamosae, K. chimalhuaca, K. creaseri, K. integrum, and K. oaxacae. K. integrum is found from central Sonora down the Pacific coast of Mexico

SONORAN HERPETOLOGIST 27 (2) 2014

and eastward across the southern Central Mexican Plateau and Valley of Mexico to the Atlantic versant (not reaching the coast). It ranks with K. hirtipes as the largest Kinosternon in Mexico and the most widespread endemic of the genus. The authors subscribe to previous work inferring the speciation of K. alamosae and K. chimalhuaca into their respective restricted ranges during a northward migration of K. integrum, however Iverson et al. (2013) finds their relationship within the group, and historic biogeography, unresolved. K. alamosae and K. integrum are found sympatrically in Sonora and are the northernmost members of their group. They are distinguished from Sonoran Kinosternon by the lack of clasping organs (see above), otherwise looking alike. K. alamosae has a bell-shaped head shield, and a single pair of barbels on the chin. K. integrum has two pairs of chin barbels, as well as two or more on the throat. A specimen of K. alamosae 200 km north of the main range of the species was likely released by humans. The distribution of K. integrum generally follows thornscrub in Sonora, and is found ca. 116 miles further north than stated (Río Mátape) at 27 km east of Baviácora in a transition zone with oak woodland (Enderson et al. 2007). Not mentioned in the book is the recent documentation of K. integrum as an introduced species to Baja California Sur (Luja et al. 2007). Both K. alamosae and K. integrum are chiefly found in temporary water, and the authors state K. alamosae has the lowest evaporative water loss of any xeric-adapted Kinosternon. Superfamily Testudinoidea: Family Emydidae: Genus Terrapene (North American Box Turtles): Terrapene ornata Species Group

In Sonora both of the species in the T. ornata group occur (as subspecies: T. nelsoni klauberi and T. ornata luteola). The two taxa represent what is generally accepted as a western or T. ornata species complex (including extinct T. longifemorale) distinct from the rest of the the genus in eastern North America. The authors present this scenario for the evolution of the T. ornata complex: populations of T. longifemorale or similar taxon expanded and contracted with the grasslands as tropical forests infringed and receded during the Pliocene and Pleistocene. Eventually T. ornata was derived, and further T. nelsoni derived from T. ornata, migrating into the tropics making it sister to T. ornata. While Minx (1996) contends that T. nelsoni sports enough primitive traits to be considered evolutionarily older, Martin et al. (2013; based on two genes) supports the sister status of T. nelsoni. Additionally they do not support of the subspecific status of a luteola subspecies, contradicting Herrmann and Rosen (2009). Specimens of T. ornata extend the southernmost distribution in Sonora stated by the authors from the Nogales-Imuris area to the vicinity of Arizpe and Nacozari (Charles H. Lowe:

UAZ1397-9, and Barry M. Campbell: UMMZ 78467). While the authors discount the presence of T. nelsoni in Chihuahua, its presence is now verified (LemosEspinal, Smith, and Chizar 2001). A first record from the Río Moctezuma is known (Lavin-Murcio et al. In prep.). Near Soyopa, a person told Buskirk (personal communication) that T. nelsoni is a hybrid between a Heloderma (Gila Monster or Beaded Lizard) and another turtle (Gopherus or Kinosternon). In Jalisco, this turtle is eaten as traditional medicine for asthma, stomach inflammation, suppression of “ética”, a “hunger not leading to obesity.” (Jimenez, pers. comm.). Genus Trachemys (Sliders)

Inferred on historical biogeography of northwestern Mexican fish, the authors treat the two native sliders of Sonora as subspecies of T. scripta despite a molecular phylogeny that recognizes the Yaqui Slider as a species (T. yaquia), and the Fuerte Slider (T. n. hiltoni) as a subspecies of the Baja California Slider (T. nebulosa) (Seidel 2002). The theories of the origin of slider turtles on the Baja California Peninsula remains conflicted between human-introduced or not (the authors, and Grismer [2002] respectively). However, their monophyly with the Fuerte Slider on the mainland is generally agreed upon. Grismer (2002) recognizes the Baja California Slider as a species (T. nebulosa), citing the accounts of 18th century missionaries who mention freshwater and land turtles, possibly precluding their initial transport from the mainland by humans. However, the authors support pre-missionary transplantation of turtles to the BCP. More genetic work determining the establishment of sliders on the BCP will dictate the appropriate taxonomy/nomenclature of the two populations. Modern transplanting of turtles from to the BCP is now well known and further complicates genetic studies. Family Geoemydidae: Rhinoclemmys pulcherrima rogerbarbouri (Western Mexican Wood Turtle)

Little is known about this species (much less about this subspecies) in the wild. The northern limit of this species is that of this subspecies in southern Sonora. Rosen (Fig. 1) observed a captive eating earth, presumably for lack of minerals in its diet (Esque and Peters 1994). Peculiar courting and mating behaviors described in the book are taken from observations of wild and captive R. p. incisa (Hidalgo 1982). This included the female biting the male after his vertical head and neck vibrations; and profuse salivation and regurgitation of food by the male apart from vocalizations typical during coitus. In the state of Jalisco, people believe R. p. rogerbarbouri to be venomous and kill them (Jimenez, personal communication).

The theories of the origin of slider turtles on the Baja California Peninsula remains conflicted between human-introduced or not (the authors, and Grismer [2002] respectively). However, their monophyly with the Fuerte Slider on the mainland is generally agreed upon.

important modus operandi, we can now thankfully avoid euthanasia with the advent of strict legal protection, photo vouchers, and less destructive techniques now possible because of museum specimens. While no large treatise is perfect, the omission of pertinent historical, taxonomic, and natural history references was surprising (e.g. Gadow 1905; Bour 2007; Lovich et al. 2010; and others [Buskirk, pers. comm.]). While the publisher’s price may be challenging, online retailers are offering it at lower prices. The electronic version is reduced in price at a well-known online book retailer and further may facilitate its use in the field with the aid of laptop computers/electronic tablets.

Family: Testudinidae: Genus Gopherus (Gopher Tortoises): Sonoran Desert Tortoise (Gopherus morafkai)

While not using the new name for Sonoran Desert forms of Desert Tortoise (G. morafkai; Murphy et al. 2011), the authors recognize the unique status of those forms, as well as those in the thornscrub and tropical deciduous forest. This is likely due to the timing of manuscript production and publication. They predict that eventually three to five taxa may ultimately be described within extant Desert Tortoise populations. Interestingly the jaguar (Panthera onca) is omitted from the varied list of predators (reported by Brown and Lopez Gonzalez 2001). Indeed chelonians comprise part of the jaguar diet throughout its range. Desert Tortoises encountered on the Baja California peninsula were once thought to be a distinct species (Xerobates lepidocephalus; Ottley and Velásquez-Solis 1989) but now considered human introductions. Grismer (2002) suggests a dwindling human-established population of the Desert Tortoise on the southern BCP, and that they may have been relictual in the northern peninsula based on the proximity of extant populations, and 18th century accounts. While the authors discount this taxon’s presence in Chihuahua, its presence is now verified (Smith et al. 2004). Conclusion

This book includes morphometric and natural history data collected over decades of field studies and correspondence by the authors, much of it previously unpublished (albeit somewhat dated). It presents a collection of photographs that may act as series displaying the variation in Mexican turtles, albeit with some of poor quality, and erroneously acknowledged or omitted photographers (Buskirk, pers. comm.). Somewhat disturbing are the written and photographic references to large series of turtles killed for museum collections. While historically being the scientifically
