The conservation of Indian reptiles: an approach with molecular aspects V.M. Sathish Kumar Southern Regional Centre, 130 Santhome High Road, Zoological Survey of India, Chennai, Tamil Nadu 600028, India Email: drsathishkumarvm@gmail.com

Taxonomy and Conservation India’s colossal biological diversity can be credited to the vast array of ecological habitats ranging from tropical, sub-tropical, temperate, alpine to desert. According to the World Biodiversity Classification, India represents two biodiversity hotspots (Western Ghats and northeastern India) and has the richest vertebrate fauna in Asia. According to Ramakrishana & Alfred (2006), the reptile fauna of India consists of about 460 species; with 244 snakes, 178 lizards, three crocodiles, and 35 turtles. Among these, 33 are considered threatened. Das (2003) reported 506 species within the political boundaries of the Republic of India. Aengals et al. (2011) accounted 518 species of reptiles which includes 3 species of crocodiles, 34 species of turtles and tortoises, 202 species of lizards and 279 species of snakes belonging to 28 families. Molur & Walker (1998) accounted about 95 endemic reptile taxa in the Western Ghats of which 62 are reported as vulnerable. However, the information on Indian reptiles is still introductory

as alpha taxonomy with the conventional outlook is yet to absorb the modern molecular trends in systematics and conservation. A large number of Institutions and Museums in the country suffer from lack of funding resources to pursue various molecular researches and many of the species predicted to be taxonomically enigmatic, or similar to known species are still awaiting formal detection using modern techniques. The Zoological Survey of India, the premier institution, has played an important role in promoting animal systematics in the country. But the National Zoological Collection housed at the Zoological Survey of India which holds the largest reptile collections in the country dates back to the early part of the 19th century; has yet to be fully entered into electronic databases. The Indian Wildlife Protection Act (1972) that legally denies permission to export any biological sample materials outside India also hinders the research activities of other developed countries on Indian reptile groups. Moreover, most species are known from very few localities and from few adults; a situation that impedes both traditional taxonomic advancement 2

and conservation efforts. In addition, the genetic information required for extensive systematic revisions for most genera is lacking. The introduction of “New Systematics” by Huxley (1940) and Mayr (1942) made/helped zoologists realise the importance of other characters to supplement the morphological characters for precise identification. This is very significant for the identification of unknown biological material when using a combination of evidences (morphology, behaviour, molecules, etc.) instead of relying on onedimensional taxonomy (Bond & Sierwald 2003; Seberg et al. 2003; Lee 2004; Will & Rubinoff 2004). Several recent studies have applied mitochondrial DNA (mtDNA) markers in phylogeographic studies to geographically widespread taxa to determine distinctive and unrecognized evolutionary lineages (e.g., Avise et al. 1992; Zamudio et al. 1997). Also, elucidation of phylogenetic relationships among closely-related taxa is critical to correctly infer a taxon (e.g. Arnold 1993; Harvey et al. 1996; Roderick & Gillespie 1998). Taxonomic studies by means of molecular techniques have contributed significantly to our perceptive of lineages contained by species or species groups. They have endorsed for revisions of taxonomically difficult groups, often re­vealing unrecognized taxa and smoothened the


REPTILE RAP #14, June 2012 progress of recognition of isolated or distinctive lineages. Molecular systematics through PCR amplification and sequencing makes the use of various molecular techniques: such as allozyme, isozyme, mitochondrial DNA (mtDNA) to provide information on the ge­ netics of wide-ranging species or species groups in isolated habitat. Therefore, molecular techniques are crucial for studies in phylogeography, because it is “the field of study concerned with the principles and processes of genealogical lineages, especially those within and among closelyrelated speciesâ€? as stated by Avise (2000). Such studies can be carried out with Indian lizard families Gekkonidae and Lacertidae as its exact phylogeny has not fully been established yet. Also, with mtDNA sequence, data, we can investigate the systematic relationships within genera or species by using the rapidly evolving control region of the mitochondrial genome. Because it has proven reliable in resolving intraspecific variation in many vertebrates including turtles (Stewart & Baker 1994; Encalada et al. 1996; Shaffer & McKnight 1996), accurately identifies closely related emydid turtle species (Lamb et al. 1994). Besides, animal genome data with potentially endless supply of evolutionary and systematic information can obviously be used to infer species diagnosis, description and identification. Consequently, the taxonomy of most organisms is better

worked out for taxa occurring in Europe and America than the tropics. Therefore, some of the current names for tropical taxa could be the first approximation to a complex biological reality. The sampling of subspecies within a species does not promise the sampling of significant variation. Phylogenetic studies of congeneric species should therefore be shared with phylogeographic surveys of haplotype dissimilarity, so that the monophyly of populations of a putative species with respect to others can be tested. As stated by Ball & Avise (1992), the discussion about the levels of intraspecific or interspecific variation necessary to distinguish species and subspecies limits has received considerable notice in the last several decades. Several current studies that have discussed the border line among inter and intraspecific variation have utilised molecular information, mostly to test existing hypotheses of species-level relationships and boundaries. At the same time, a number of formerly documented subspecies genetically match though morphologically they overlap, implying that they probably should not be recognized at any taxonomic level. Parallel work on the snake Pituophis melanoleucus points that the conventional outlook suggested by Conant (1956) for the single polytypic species is conflicting with the molecular evidence, and 3

Painted Turtles Chrysemys picta present an additional outstanding prospect to explore the question of species boundaries within a widespread species complex. According to Bishop & Schmidt (1931), the genus Chrysemys as currently recognized contains a single extant species, C. picta. Four subspecies are generally recognized: Chrysemys picta bellii, C.p. dorsalis, C.p. marginata, and C.p. picta. Thus, decisions regarding species and subspecies boundaries can, and do have dramatic impacts on species conservation and management (Shaffer et al. 2000). After almost three centuries of herpetological work in India, a good number of research papers have been published. Though, the main comprehensive works would indisputably have been by Malcolm A. Smith, and there is no wonder that it took more than twelve years for him to produce these three separate volumes on Indian reptiles. Smith (1931) systematically placed the crocodiles and turtles in Volume I, the lizards in Volume II (1935), and the snakes in Volume III (1943). These precious classics have long been regarded as fundamental references in the library of any herpetologist interested in Indian regions. Further contributions were made by Tiwari & Biswas (1973), Sharma (1977, 1978, 1981, 1998, 2002, 2007), Murthy (1985, 1994, 2010), Das (1991, 1994, 1996, 1997

(2007), Mukherjee and Bhupathy (2007), Sharma (2007), Thorpe et. al. (2007), Giri (2008), Giri & Bauer (2008), Das & Vijayakumar (2009), Giri et al. (2009a), Giri et al.

Today, about 518 species of reptiles which includes three species of crocodiles, 34 species of turtles and tortoises, 202 species of lizards and 279 species of snakes belonging to 28 families (Aengals et al. 2011) are found in India. The poorly resolved taxonomies among some families (e.g. Uropeltidae, Agamidae) has created some confusion in Indian reptile taxonomy than in other vertebrates of the more complex groups and numerous new species sit in laboratories/collection halls awaiting more detailed studies based on genetic data. The recent taxonomic revisions have elevated the number of endemic uropeltid species to 47 (based on morphology). For instance, David (2003) stated that the taxonomy of uropeltids is unstable and is likely to be substantially revised in future. For such groups, interspecific hybridisation could be very common. Therefore,

very apparent as they are terrestrial. Forest species are more vulnerable due to their lack of ability to resist the high temper­atures of open formations. Most common and widely distributed species are more resistant, but many will disappear when their habitats are totally eliminated. Moreover, people fear or dislike snakes; they tend to be killed whenever they are seen. Crocodiles and turtles are hunted for their meat and eggs. Construction of hydroelectric dams alters the entire habitat in the area of the reservoir, thus should be treated as a real local threat. Even as animals run away, large numbers are rescued and dumped in nearby forests, even though the impacts on the ecology and biology of the nearby populations are mostly unknown as stated by Pavan (2002). Dams are likely to cause huge potential impacts on the reproductive bi­ology of the turtle and crocodile populations downstream and on the population formation of lizards and snakes even though these impacts may not be instantly evident. The smaller forest reptiles are very vulnerable to mi­ croclimate changes. Agro­ chemicals are another major threat and may be especially serious in small protected areas surrounded by agricul­ tural land. The long-term Principal threats effects of these threats need Habitat alteration is the to be understood in order to major threat. The impacts delineate appropriate conser­ on lizards and snakes are vation strategies. Therefore, according to biological species concept, the whole group is to be placed and treated under a complex species. Since many subspecies are not distinct species, they are reproductively compatible and will periodically interbreed with adjacent subspecies. These breeds pose several problems to the evolutionary zoologist and could be misidentified as a new species adding up to more confusion. This could be because the zoologists confined their studies mainly to the morphological characters, ignoring the detailed analysis of the interspecific and intergeneric breeds and most of their descriptions were based on single “type” specimens. Members of a subspecies share a unique geographical range or habitat, a group of recognizable genetically controlled characteristics, morphological or molecular, and a unique natural history as compared to other subspecies. Accordingly, those who adhere to purely morphological species concept should also refer to the genetic characteristics before assigning any taxonomic status to the sample. However, bear in mind that all subspecies have the potential to suitable adaptations to their specific ecological habitat and also have the potential to evolve in to a new species.

should also include finding out the effects of geographic barriers, such as larger rivers, mountains or national highways which could restrict the movements of reptiles between populations, thus preventing any genetic exchange between them. The absence of data is not a firm basis for being indifferent to claims of reptilian declines. One simple response is to call for immediate monitoring programs, but this requires additional consideration of, for example, how monitoring should be undertaken and which species and habitats should be investigated. To begin to address these questions, more fundamental research in reptilian biology is needed. In particular, geneticbased research will improve the knowledge of reptilian biology and will dramatically increase the chances of identifying instances of possible decline that merit dedicated study. Species that have not been reported for many years, often since their initial description, should be the main concern for accurate and precise revisions of conservation-status data. The key in conservation assessment is to find out isolated or patchy populations in order to formulate conservation strategies. Therefore, gaining an understanding of diversity pat­ terns, monitoring the genetic variability of populations in fragments, and comparing them to populations isolated at different times in the

Records of Indian Egg Eater Snake Elachistodon westermanni in the localities of Shegaon, District Buldhana, Maharashtra, India Abhishek Narayanan Project Coordinator, Rescue, Conservation and Education, Wildlife SOS 48, Ayodhya Nagar, Near Vatika, Shegaon, Buldhana, Maharashtra 444203, India Email: narayanan.abhishek@gmail.com

The following record is completely accidental and no systemic survey technique or search method was utilized for the same. The Indian Egg Eater Snake is the only snake of the genus Elachistodon recorded in the Indian subcontinent. As the name suggests, its diet primarily consists of eggs though not exclusively (known to eat geckos in captivity) (Gans & Williams 1954). Similar to its African counterpart, a snake belonging to genus Dyspeltis, it has elongated inferior processes of the anterior thoracic vertebrae. They are not only coated with enamel, but also penetrate the esophagus, which assists these snakes to break the egg shell inside the throat, and release the protein-rich yolk inside the gut (Boulenger 1890). Indian Egg Eater Snake was thought to be extinct by Murthy et all. (1993). According to Malcolm smith et al. about five specimens were recorded until late 1943 from the areas surrounding Jalpaiguri District in northern Bengal Smith (1943). Captain et al. (2005) recorded it for the first time in Wardha

District of Maharashtra based on a dead specimen. Thirteen specimens (seven live, six dead) were recorded in and around Amravati District by Nande et al. (2007). Apart from this there have been several unpublished records the snake in certain localities of Vidharbha region of Maharashtra. Raju Vyas also published some photographic records in 2010 of this snake in Gujarat. Considered extremely rare, and from isolated locations (as detailed in Table 1) it was considered as one of the least found snake species on the Indian subcontinent (Khaire 2010). Its behavior and habits are relatively unknown (Dandge 2007), and only its diet and

description is available in the existing literature (Khaire 2010). A snake was rescued late night at around 1100hr in the garden of a house in the locality of Shivaji Nagar, Shegaon, Maharashtra (2109’43”N & 7904’ 47”E) by Karan Thakur of Snake Rescue Volunteers, a local NGO working in the area of study. Being unable to identify the snake on the first instance, it was decided to keep the snake for later identification provisionally being identified as an ‘Indian Egg Eater’ on the basis of descriptive photos given in the Handbook by Khaire (2010). Till then the snake was kept in a plastic translucent box with holes on the lid and adequate hiding was provided. The snake was measured, photographed and the scales counted. The snake was identified as Indian Egg Eater Elachistodon westermanni based on the holotype descriptions in the literature (Wall 1913; Gans & Williams 1954; Rosenberg & Gans 1976). For confirmation

Inference: The snake has been previously recorded from Man Khettra, Junagarh District; Sasan-Gir and Surat in Gujarat followed by Amravati and Wardha districts in Maharashtra. This current record thus fills in the gap in the distribution from the south-western borders of Gujarat to north-eastern borders of Maharashtra comprised of Saurashtra region, around Vadodara District in East Gujarat, South Gujarat and entire stretch of Vidharbha Region. This land is

An observation on death of Python molurus feeding on a male Spotted Deer Axis axis

morning of 02 July 2011 we were on our way to check the results of a camera trap device that we had placed in the Gara-Amgadi region of the park for monitoring leopards and tigers. There was some strange stench

Ecological studies on python have showed that they feed on a variety of animals including frogs, rodents, wild cats, peafowl and ungulates like Barking Deer, Chinkara and Spotted Deer (Daniel 1983) There have been several cases where python death occurred due to movement of the prey in the gut region due to suffocation or the body is pierced by horns and antlers (Sharma 2004) We observed one such incidence in the Chilla range of Rajaji National Park, Uttarakhand in July 2011. I was working on a summer training project on monitoring of mammals in

in the area and following the source of the smell, we observed a pair of antlers in the nearby bushes. On moving closer to the site we saw a dead python, with an approximate length of 3.5– 4 m and a dead adult male Spotted Deer (Image 1). The male Spotted Deer had been killed by the python, but was swallowed partially till the neck region (Images 2–3). The antler and the jaw bones of the Spotted Deer could be seen as they had pierced the body (posterior oral region) of the python. We suspect that the python must have tried to swallow its prey, but maybe as a result of

a sudden sideways movement to facilitate swallowing or a sudden injury by the rock present beside the body of the python, the antlers and the jaws must have pierced through the body (Image 4). The oral cavity of the python was left wide open as the head region of the deer was found entangled in the oral region of the python (Image 5). The incident must be a day or two old as beetles and flies had already started scavenging and decay of several body parts was prominent. References Daniel, J.C. (1983). The Book of Indian Reptiles.

Mumbai (formerly known as Bombay), considered to be the economical capital of India, is a unique city where two kinds of jungles – a concrete jungle and a real forest co-exist with each other. Despite the increasing habitat destruction resulting from mounting population in the city of Mumbai, it still has rich biodiversity. Mumbai’s biodiversity is a product of confluence of Arabian Sea to the west and the Western Ghats to the east. Vidyanagari campus of University of Mumbai (19004’18.5”N & 72051’21.5”E) is situated at Kalina, Santacruz which is a central suburb of Mumbai City having an area of 230 acres. In spite of the number of development and construction activities going on in the University campus, it still possesses a good vegetation cover providing habitat for a variety of fauna. Although a few attempts have been made by Jadhav et al. (2007) and Upadhye et al. (2008) to study floral and avifaunal diversity of the campus, respectively, there is absolutely no scientific report focusing exclusively on herpetofaunal diversity of the campus. Considering the ecological importance of

herpetofauna, the present study was undertaken. Methods The study was carried out for a total duration of 24 months from May 2008 to April 2010. Amphibians and reptiles encountered during extensive field trips were captured, photographed (whenever possible) and carefully identified with the help of field guides (Daniel, 1983; Das 2002; Whitaker & Captain 2004) before release. Snakes were identified using scale count as described by Smith (1943) and Daniel (1983). Nomenclature adopted here is as given by Das (1994) and Dutta (1997) for reptiles and amphibians, respectively. Venomous snakes were released away from the human settlements at the

outskirts of the campus where there is vast, unused land with thick vegetation. Record of specimens killed under vehicles and by humans was also made. The status of each species was observed in four categories on the basis of total number of each species encountered or sighted during the entire survey. The category values were: rare (1–4), uncommon (5–14), common (15–29) and abundant (greater than 29). Results Amphibians: Six species of amphibians were recorded at the campus during the study period. Only three specimens of Narrow-mouthed Frog were spotted during the study while the Common Indian Toad Duttaphrynus melanostictus and Skittering Frog Euphlyctis cyanophlyctis were abundantly seen and remaining three species of amphibians (one species of toad and two of frogs) were common (Table 1). The Common Indian Toads were frequently found hiding under the platforms in classrooms. Reptiles: The status of the 21 species of reptiles belonging to 17 genera and

specimens of Indian Flapshell Turtle Lissemys punctata were rescued from the road bordering the vast marshy wetlands in the monsoon, which may have come accidentally onto the road (on land) for laying eggs. They were released safely back into the adjacent riverine habitat. Among the 12 species of snakes recorded on the campus, nine were found to belong to the family Colubridae, out of which only one was semi-venomous and the rest were non-venomous. Rat Snake, Checkered Keelback and Buff-striped Keelback were seen abundantly on the campus. Buff-striped Keelbacks were seen in great numbers in monsoon season as they gathered for mating. Checkered Keelbacks were sighted near the pond and in the canals of the campus, mainly near water resources. Couple of road-killed specimens of Checkered Keelbacks were seen. A number of nonvenomous Rat Snakes were rescued from the academic buildings during the study and released. The longest specimen measured just over 2.4m. Rat Snakes were also found to be killed by grass cutters in the campus as these are commonly mistaken for the venomous Spectacled Cobra. Even though, two of the big fours in India—Russell’s’ Viper and Spectacled Cobra—were found to be quite common at the campus, fortunately no human bite cases have been recorded.

Discussion The present results indicate that Vidyanagari campus of Mumbai University is considerably richer in terms of its herpetofaunal diversity when compared to observationsmade by Wadatkar (2004) in the campus of University of Amravati. The investigator reported 12 species of snakes, two species of geckos, three species of skinks and one species of Calotes in his study. These observations are significantly important when considering the fact that unlike that of Vidyanagari campus of Mumbai University the Amravati University campus is covered by hilly forested area and

therefore, ideally expected to be richer in herpetofauna. However, Bengal Monitor Varanus bengalensis which was reported to be common at Amravati campus was found to be totally absent at Mumbai University campus. The significance of herpetofauna in ecology needs no emphasis. The insect populations are regulated by amphibians such as toads and frogs along with reptiles like lizards and skinks. Snakes are of tremendous importance in the food chain as they keep the population of rats and mice under check. Nowadays, biodiversity in urban areas is threatened by urbanization, pollution, habitat destruction, climate change, introduction of alien species and extinction cascade where extinction of one species causes extinction of other (Jadhav et al. 2007). The rich herpetofaunal diversity observed in the present survey could be attributed to the suitable habitats such as gardens, marshy wetlands, grasslands, ponds, canals and to the presence of variety of plant types like herbs, shrubs, trees, bamboos etc. (over 292 plant species: Jadhav et al. 2007) in the University campus providing shelter and food for a vast array of species. The need for green spaces like Vidyanagari campus which provides a safe haven for various species cannot be overemphasized. The present study which is the first ever study of herpetofauna of the campus,

is hoped to be useful for the scientific community, students and to the teaching and nonteaching staff of the campus to add to the present knowledge. Awareness lectures are being arranged at the campus for a better consciousness about herpetofauna and for requesting people not to kill herpetofauna, especially snakes. References Daniel, J.C.

Water is the fundamental need of all living organisms. Without water, life is impossible. Depending on the type of wetland, many species of life forms i.e. high biological diversity is found in and around them. Wetlands are classified on the basis of quality and quantity of the water. The lack of easy availability of this liquid gold i.e. water, either in terms of quality or the quantity or both parameters, has led us (human beings) to search other alternatives to fulfill our water requirements. Presently, it has been noted that the species diversity of inland water ecosystems is most threatened and in many parts of the world, it is in continuous and accelerating decline (MEA 2006). In India, as elsewhere in the world, freshwater and freshwaterdependent ecosystems provide a range of ecological services for humans like drinking water, fish, flood protection and wildlife (Postel 1998; Revenga & Kura 2003). As population and associated water demands increase, balancing the requirement between

the aquatic environment and developmental needs is becoming critical in many of the world’s river basins, India being no exception (WII 2010). To fulfill our basic needs and requirements, we develop or construct a new water body, either as a dam on river systems, or as rainwater collected in artificial earthen depressions or by creating water reservoirs or by other alternatives like the use of ground water by constructing wells, hand pumps and other such extraction mechanisms. Such kind of man-made water bodies are the results of alteration of a large area of habitat; either the forestlands or scrublands getting submerged in water. These kinds of water bodies support many types of biodiversity. We know the irrigation and agricultural values, but are still ignorant about the types of biodiversity actually/ directly supported by such kind of man-made water bodies. Therefore, we explored five representative manmade water bodies in central and northern Gujarat, with a 21

view to prepare an inventory of biodiversity, especially herpetofauna found in and around the man-made water bodies. We have also tried to assess the true significance of the water bodies other than the agricultural importance. Objectives The study was carried out with the following objectives, (i) To collect the base line information of reptiles and amphibians in and around the water bodies, (ii) To study the status of herpetofauna from these areas, (iii) To know the importance of such kind of water bodies from the viewpoint of biodiversity conservation, (iv) To suggest multipurpose management for versatile use without the violation of original objectives and purpose of the water bodies. Study area There are various sizes of man-made water bodies available in various biodiversity zones. It is also found that they are either surrounded with agricultural fields or share boundaries with protected areas of the state. Therefore, the study was conducted in five man-made water bodies, namely: (i) Hathmati dam, (ii) Dantiwada dam, (iii) Deo dam, (iv) Kanewal water tank and (v) Pariej water tank (Fig. 1). The first three water bodies are “dam� type water bodies and are built on river systems, namely Hathmati

River, Banas River and DevDhadhar River, respectively and the remaining two water bodies; Kanewal and Pariej are “water tank” type water bodies and are filled by the waters of Mahi and Narmada irrigation canals of Vanakbori Dam and Sardar Sarovar (Narmada Dam). First three water bodies are for irrigation purpose, whereas the waters of Kanewal and Pariej water tanks are utilized for irrigational purpose and as drinking water by the surrounding towns and villages. The topographic, salient features and other

relevant details of the water bodies are mentioned in Table 1. Methods All these five water bodies were surveyed in various seasons, during 2004 and 2005. A total of 30 field days were spent for the study, to find out the estimate of species of amphibian and reptiles surviving in and around these water bodies. This is considering the area around the water body as ‘500m area from the demarcation of high water marks of the particular water 22

body’. Each one of the identified water bodies was surveyed through a rapid survey and various potential areas were selected surrounding the water bodies for the aspect of availability of amphibians and reptilian species. These habitats were intensively explored (especially microhabitats) through repeated visits in various seasons. During the study, all the important species have been documented through the colored photographs and as and when close examination was required, the animals were caught with various known methods of catching amphibians and reptiles. All caught animals were released in the same habitat after recording the necessary data. All collected specimens were examined and carefully identified by using the diagnostic keys, given by Smith (1935, 1943) and Daniel (1963a, 1963b and 1975) & Daniels (1997) and nomenclatures adopted here are those of Das (1994 & 2003), Dutta (1997) and Frost et al. (2006) for reptiles and amphibians, respectively. Field surveys: (a) visual encounter surveys, (b) watching aquatic reptilian species through the field binoculars (10x50), and (c) recording the species through indirect evidences like shell, molt/moult and sound.

gathered from local people of surrounding villages, staff of forest department and irrigation department. Other wildlife enthusiasts were also inquired about the presence of different species of amphibians and reptiles by showing the colour pictures of the species. Results and Discussion During the study period, we were able to collect information about the availability of nine species of amphibians belonging to four families (Table 2) and 25 species of reptiles belonging to 14 families (Table 3) from in and around the earlier mentioned five water bodies of Gujarat State. Of which, nine species are toads and frogs, one species of crocodile, two species of turtles, twelve species of lizards and ten species of snakes. The record of availability of herpetofauna at each water body shows that the highest number of amphibians and reptilian species were recorded from

The Common Indian Wolf Snake Lycodon aulicus was recorded at Kanewal water tank only. Present study indicates a good amphibian and reptilian diversity supported by manmade water bodies. The amphibian and reptilian diversity is dependant on the surrounding habitat of these water bodies. The highest diversity was recorded at Deo and Dantiwada dams because both the water bodies are situated very close to the protected areas and in river basin areas which included agricultural fields also. Whereas, lower diversity was recorded at Kanewal and Pariej water

tanks because both the wetlands are situated on the plains with earthen bunds

on their periphery and are surrounded by agricultural fields. These two wetlands are far away from the forests and protected areas. Here, we come across a valuable suggestion after the present study that Gujarat State has over 300 manmade water bodies ranging from small to large sizes. The concerned criteria for further actions should not only be the utility of the water and the size of these reservoirs but also the overall biodiversity existent in and around the water body. Our experience with the department of irrigation suggests that they consider a solitary point of view and that point is the

The Malabar Pit Viper, Trimeresurus malabaricus (Jerdon, 1854) is a mediumsized snake, endemic to the tropical rainforests of the Western Ghats occurring between 123m and 2134m above sea level on bushes, trees and rocks, often in close proximity to forest streams (Whitaker & Captain

2008; Sawant et al. 2010). Being polymorphic, the basic colour profile of a Malabar Pit Viper varies between green, olive, brown, yellow, blue, reddish-brown and maroon, speckled with black and brown spots which may form a zigzag pattern (Whitaker & Captain 2008). In this note we describe the sighting of

a morph of T. malabaricus from the semi-evergreen forests of the Vazhachal Forest Division (10019’48.5”N & 76040’8.4”E) in the Kerala region of Western Ghats. Our sighting was made at an elevation of 694m, and the viper was found resting on a dry twig, 9cm from the forest floor, with relatively little undergrowth, beside a forest path at 1650hr on 15th January 2011. The specimen was orange yellow in color and was without the typical brown or black spots on the body, characteristic of the other morphs (Whitaker & Captain 2008). In this specimen, the prominent spots were replaced by a darker orange tone forming a zigzag pattern identical to the other variations. The

coloration on the head was uniform and without the usual speckled appearance (Images 1 & 2). The individual was identified as T. malabaricus by its large and distinct triangular head, weak keels on dorsal scales, 19 dorsal scales at midbody, nine supralabials and 11 infralabials. Many vipers in India like the Saw-scaled Viper Echis carinatus, Humpnosed Pit Viper Hypnale hypnale, Cantor’s Pit Viper Trimeresurus cantor, and Malabar Pit Viper exhibit polymorphism (Whitaker & Captain 2008). The reason for polymorphism, however, has not been investigated in any of these species. Pit vipers from the Goa region of the Western Ghats have

been suggested to be habitat specific, their distribution being affected by seasonal changes in temperature and humidity (Sawant et al. 2010). If this distribution is unaffected by detectability of the species due to seasonal difference, polymorphism exhibited by the Malabar Pit Viper may not be due to thermoregulation but rather for camouflage. Additional factors such as locality (see Kark et al. 1997) and wider habitat use (Sawant et al. 2010) may also influence polymorphism. References Kark, S., I. Warburg & Y.L. Werner (1997).

Sightings of King Cobra Ophiophagus hannah in northern coastal Andhra Pradesh K.L.N. Murthy 1 & K.V. Ramana Murthy 2 1 Biologist, Indira Gandhi Zoological Park, Visakhapatnam, Andhra Pradesh 530040, India 2 Executive Director, Green Mercy, Srikakulam, Andhra Pradesh, India Email: 1 klnmurthy25@gmail.com, 2 green333mercy@gmail.com

The King Cobra Ophiophagus hannah Cantor, 1836, is the largest venomous snake in the world, reaching to a length of up to 5.85m (Aagaard 1924). Although not a common snake, the species has a wide distribution (David & Vogel 1996). This monotypic genus of the family Elapidae is considered as a species complex by Das (2002), as the species varies in coloration, scalation and body proportion throughout its range. In India, the distribution range of the species is recorded as Western Ghats, Uttar Pradesh (Terai), Bihar, Orissa, West Bengal, northeastern India and also the Andaman Islands (Whitaker & Captain 2004). In its distributional range, the species is recorded from various habitat types such as lowland, wet tropical forest, coastal rainforest, tropical and subtropical wet montane forest, dry forest, swamps and marshes, open scrubland, plantation and cultivated areas, alluvial and terai grassland, mangrove swamps, open country and disturbed areas, and near human habitations (Narayan & Rosalind 1989; David & Vogel 1996; Selich & Këstle

2002; Leviton et al. 2003). The King Cobra is listed under Schedule II of the Indian Wildlife (Protection) Act, 1972; Appendix II of CITES; and in the Vulnerable category by IUCN (2010) which also recommends research into, and monitoring of the population status of this species to gain a better understanding of how the population responds to threats and conservation. In the present paper, we report the sightings of Ophiophagus hannah from different locations

in the northern coastal Andhra Pradesh region (18012’10.83” & 83004’30.95” to 18048’38.31”N & 0 83 48’52.44”N approximately) over the last few years (Image 1). Two large male King Cobras were even killed by locals on two separate occasions in this region which encompasses three districts of Srikakulam, Vizianagaram and Visakhapatnam respectively. A 4.26m long male King Cobra (Images 2 & 3) was spotted dead by volunteers of Green Mercy (an NGO working for wildlife conservation in the three districts) on 28th July 2009, at Sitampeta forest area 18040’33.96”N & 83048’27.11”E in Srikakulam (Murthy & Murthy 2010). The dead King Cobra weighed about 6.5kg and as the specimen was decomposing

fast, it was carried to a nearby science college and preserved in 10% formalin solution. On enquiring, it was learnt that the snake was killed by people from surrounding villages. In another incident, a 3.84m long male King Cobra weighing 5.7kg was stoned to death by locals (Images 4 & 5) at Kapusompuram,

a small village near S. Kota Town 18006’57.67”N & 0 83 04’35.23”E. This incident took place on 30 October 2010. King Cobras have been sighted here by locals, forest department personnel and members of Green Mercy Organization in the recent past. The geographic region of 30

north Coastal Andhra has varied habitats ranging from coasts to dry, thorny, scrub to dry, deciduous forests and sal forests. Small pockets of semi-evergreen and moist deciduous forests do exist in Makkuva, Duggeru and Salur forest blocks of Vizianagaram Division. This division occupies a very strategic position owing to the fact that many wild animals including elephants wander into this district from the adjacent state of Orissa on a regular basis. There are unconfirmed occasional sightings of King Cobras by locals from this region and also few other locations in Srikakulam and Visakhapatnam divisions as well. Direct evidence like actual sightings, killings by humans as well as indirect evidence in the form of shed skins, skeletal remains, tracks, and deserted leaf nests clearly suggests the occurrence of the species in this region. Furthermore, there have been reports in the local electronic and print media about sightings and killings of King Cobras with visuals. The species was also sighted by locals near Sunnapu Gedda Waterfalls in the adjoining Sitampet mandal of Srikakulam District which lies at Andhra-Orissa border (K.V. Ramana Murthy, Green Mercy, 25-08-2010 pers. comm. ). There is an apparent dearth of information regarding the exact distributional status of the species in northern coastal Andhra Pradesh due

to paucity of herpetological surveys. Invariably, it is a serious impediment for chalking out conservation management strategies. Lack of awareness and prevalent myths lead to unnecessary killing of these majestic serpents. Perhaps, habitat destruction, poaching and redundant killings by locals are taking a heavy toll on the resident King Cobra

population. Developing interlinking corridors between forest areas i.e., from S.Kota – Araku-Salur – Duggeru– Parvathipuram and Sitampeta regions could be useful for the long-term survival of King Cobra populations in Andhra Pradesh. Therefore, we recommend that immediate intensive surveys be carried out in all the three districts of northern 31

The Kerala Agricultural University (KAU) main campus is located at Vellanikkara, Thrissur District, Kerala (Fig. 1 & Image 1). The campus has a total area of 391.44ha having garden lands, botanical garden, plantations of Coconut Cocos nucifera, Rubber Hevea braziliensis, Arecanut Areca catechu, Cocoa Theobroma cacao, Plantain Musa paradisiaca, and orchards of Mango Mangifera indica, Jack Artocarpus heterophyllus, Sapota Manilkara achras and Guava Psidium guajava and Fodder Grasses Pennisetum pedicellatum. The KAU campus is very near to the Peechi-Vazhani Wildlife Sanctuary, Western Ghats, the aerial distance of which is not more than 4–5 km. KAU campus is located south of the Palghat Gap. KAU campus enjoys a moderate climate. The main source of atmospheric precipitation is the south-west and north-east monsoons. The greater portion of the rain is from south-west monsoon between June and September. The 10-year mean minimum temperature is 23.30C and 10-year mean

maximum of 31.80C. The mean annual rainfall is 2763mm. The mean number of rainy days per year is 110 days (KAU weather station, 2010). Out of the 275 species of snakes of India (Whitaker & Captain 2004), Kerala has 102 species (Palot & Radhakrishnan 2011). Family Elapidae is represented by 17 species in six genera in India, out of which seven species in four genera are known from Kerala. Among the five species of coral snakes known to occur in India, four belong to the genus Calliophis and all these are found in peninsular India (Deepak et al. 2010)

and all the four species are known from Kerala too. They are Calliophis beddomei, C. bibroni, C. nigrescens and C. melanurus (Palot & Radhakrishnan 2011). Present observation During the course of the ongoing herpetological survey in the KAU campus we discovered a Slender Coral Snake Calliophis melanurus on 16 June 2011. The specimen has a total length of 155mm, including the tail length of 15mm. This is much smaller than the total length measurements given in Smith (1943), indicating that it was probably a juvenile individual. The morphometric details of the snake including the scalation are given in Table 1. The scalation details of Slender Coral Snake obtained from KAU campus were compared with the scalation details for the Slender Coral Snake given in Smith (1943) and Whitaker & Captain (2004). The KAU

specimen has 38 subcaudal scales and based on this it can be concluded that it was a male individual. The GPS readings of the location from where the specimen was obtained are 76016’45.4”E and 10032’46.6”N, at an altitude of 43m. Description Slender Coral Snake is an extremely slender bodied, mildly venomous snake with smooth scales (Images 2 & 3). The head and neck black, back light brown, tail brown with two black rings, one at the base and other near the tip of the tail, under side coral red. The snake when disturbed raised and coiled the tail.

Distribution Smith (1943) gives the distribution range of Slender Coral Snake from Bengal, Nagpur, Bombay, Dharwar, Malabar, Coimbatore, Anamalais and Sri Lanka. Molur & Walker (1998), give the distribution range of Calliophis melanurus as

Maharastra, Karnataka, Tamil Nadu and West Bengal. Whitaker & Captain (2004) give the Slender Coral Snakes definite records from Gujarat, Maharashtra, Karnataka, Tamil Nadu and West Bengal. There is a single record from Dhar, Madhya Pradesh (Vyas & Vyas 1981) and Nallamala,

northern Andhra Pradesh (Sharma 1971; Sanyal et al. 1993). Recently Guptha & Rajasekhar (2011) reported Calliophis melanurus from the Eastern Ghats. Thus the present record of the Calliophis melanurus from the Kerala Agricultural University campus, Vellanikkara, Thrissur District, in Kerala is of interest. As this is the first record of this species from south of the Palghat Gap, Western Ghats. All other published records of this species were from north of Palghat Gap. References

REPTILE RAP #14, June 2012

UGC Sponsored Major Research Project on Herpetofauna Project Title: “Herpetofaunal Diversity of Sonitpur District, Assam and Adjacent Arunachal Pradesh India with Special Reference to Ecobiology and Breeding Behaviour of Certain Rare Species” i. Principal Investigator: Dr. Mohini Mohan Borah Ii. Designation: Assistant Professor in Zoology iii. Address: a. Office: Chaiduar College, Gohpur, Sonitpur, Assam 784168 b. Residence: Ward No.-6, Madhya Chatrang, P.O- Gohpur, Sonitpur, Assam 784168 iv. UGC Approve No. & Date: F.No.-39-619/2010(SR) Dt. 12th January 2011. v. Duration of Project: 3 Years w. e. f. 01-02-2011. vi. PI in brief: The proposer of the project did his PhD on the topic “A study on distribution of amphibian fauna of Arunachal Pradesh with special reference to habitat ecology of tadpoles”. He has published 48 papers in different journals and national and international seminars. He has completed a UGC sponsored MRP on the topic “Exploration of aquatic fauna of Sonitpur District, Assam with emphasis on conservation measures” the result of which would be additional value of the proposed project. He has constant touch with famous herpetologists of the country and abroad. As these, he achieved a significant milestone in organising a programme at his own college on 07 may 2008 on the occasion of International Year of Frog, 2008 by the gracious participation of Prof. Dr. Annemarie Ohler, Curator of reptiles and amphibians, Museum National d’Histoire Naturelle, Paris, France and Dr. Stephans Grosjean, Assistant Professor of the same institute. The proposer is one of the contributor of the book “ Threatened Amphibians of the World ” published by, LYNX, Spain in 2008. vii. Executive summery of the ongoing Project: The northeastern region of India along with eastern Himalaya is recognized as one of the global bio-diversity hotspot region of the world. The eastern Himalayan region is unique in all aspects of bio-diversity, ecosystem, topography, climate and anthropological diversity. The region is a gateway to the Indian region for migration from Myanmar, China, Bangladesh, Nepal, Bhutan etc. Major portion of the region is still largely inaccessible and less degraded ecologically than the main land of India, but is rather extremely fragile, vulnerable and falls under the highly seismic zone. The National Conservation Strategy, 1992, outlines the policy action required to give greater attention to biodiversity conservation. The present study area ,i.e , Sonitpur District of Assam occupies 5,324km2 bordered with state of Arunachal Pradesh in the north and river Brahmaputra in the south. Though the study area comprises a significant portion of eastern Himalayan hotspot of biodiversity, and yet it is one amongst the least known. Various wild life surveys in the last decade mention mainly on mammals and birds. The reptilian species diversity in the present study site is still not fully understood except very few sporadic survey reports. Many of the checklist of amphibian and reptilian species of northeastern India need further authentication and many new species of Indo-Chinese elements are likely to occur. The aim of this ongoing project is to make a detailed investigation on amphibian and reptilian habitat of Sonitpur District of Assam and adjacent Arunachal Pradesh. A few physico-chemical parameter will be analysed in the diversed habitats of amphibians and reptilians of study site. The inhabitants over the years acquired unique knowledge about the use of amphibian and reptilian species as food, medicine and ornaments. A detailed ethnomedicozoological study may highlight various applications of animal species and could provide a scope of knowledge for developing indigenous economy and environmental security. The year 2008 has been declared as International Year of Frog because of their key role in ecological communities. They are considered as important bioindicators of global climatic chang. Significant declines and apparent extinctions among numerous species were noted by researchers all over the world since 1980. The pressure on amphibian and reptilian habitat can be recorded only when detailed investigations on ecology, food habit , biology and taxonomic study is available. Study of distributional pattern or zoogeography of a species provides information on ranges of their natural distribution and boundaries that help to find out the endemic status of a species. The use of different species of frogs, lizards, tortoises, snake etc. by a indigenous people as food and medicine indicate its potential for economic and academic importance. viii. Significance of the study: Initially any research and developmental programme survey and demarcation are basic necessities to be carried out in the beginning. Scientific knowledge on biodiversity in general and herpeto fauna in particular of the Sonitpur District is surprisingly deficient. Most of the area in the district is unique ecologically and faunastically. Another important consideration is a great variation in relationship of people to biodiversity and ecosystem which are social, economic, cultural and scientific importance. This project will help in bringing out first hand information and resources data base on the various aspects of biological studies on the lesser known herpetofauna of Sonitpur district of Assam and adjacent Arunachal Pradesh. The results of the project may provide useful information to the researchers, various state government departments, NGO’s, Indian Council of Medical Research, IUCN, Species Survival Group (SSG), Zoological Survey of India (ZSI), Indian Council of Agricultural Research (ICAR), Declining Amphibian Population Task Force (DAPTF), Bombay Natural History Society (BNHS), Zoo Outreach Organization (ZOO), Forest Research Institutes, Universities, Local entrepreneurs, etc.
