odd Esque has been a Research Ecologist with the Western Ecological Research Center, USGS since 1996. He leads and collaborates on a variety of projects in arid systems involving disturbance ecology herpetology, plant demography, fire ecology, habitat modeling, and landscape ecology. Many of his current projects are interdisciplinary in nature and include: determining the influences of renewable energy and recreation on natural resources; quantifying the impacts of international border activities on biota and their habitats; designing and implementing projects to determine the efficacy of mitigation measures for surface-disturbing activities;

and consulting on a variety of landscape-scale interagency initiatives (e.g., State Wildlife Action Plans, Landscape Conservation Cooperative, and Rapid Ecoregional Assessments). Species-centric work includes: determining pathways and rates of disease transmission, quantifying physiological stress, detecting gene expression of stress, and dietary and habitat needs of healthy desert tortoises. Although challenging in a variety of ways, the integrated research approach is often necessary to tackle difficult resource issues that confront society today. Todd enjoys nature photography, flying experimental aircraft, and growing desert plants.

Herping Arizona—2011 in Review

t is the sincere wish of this author that the Tucson Herpetological Society—as it exists today—had been in full swing in 1981. Had this been the case, it is likely that said author would have been better prepared to face the events that followed. 1981 is the year that he arrived in Arizona. He wanted nothing more than fellowship with those of like mind in herpetological matters. But there was nobody for him at the time. Whatever herpetological cliques there may have been were secretive—impossible to penetrate by the staunch and non-inclusive invisibility of the herpetologists of that era. When it came to befriending the local herpers, the great poet and songwriter Jim Morrison Image of an in situ adult Gila Monster (Heloderma suspectum) sharing a shelter with a could not have put it better: “People juvenile Western Diamond-backed Rattlesnake (Crotalus atrox). 2011 was a good year are strange, when you’re a stranger...” for encountering both species.

Between January through June, the Tucson International Airport received a paltry 0.58 inches (14.73 mm) of rain. This is the second driest period for that duration in local weather history! And we had zero measurable rain from 10 April until 29 June. These 81 days were the fourth longest dry spell in weather history for Tucson. What then followed was the abysmal monsoon season.

highlight the fact that the 12.23 inches (310.64 mm) of precipitation at Tucson International Airport ranks as the second highest total for the 12 year time period of this century. That being thusly highlighted, we move on to the good stuff. When addressing the herps on this table, we are first going to break tradition here, and talk about a lizard not on the chart. We speak of the Long-nosed Leopard Lizard (Gambelia wislizenii). The number of these encountered in 2011 was a big, fat goose egg! Zip! Zero. That is the first time that this has happened during the time period under discussion. I have seen as many as 16 in 2001, and as few as 1 in 2006. I have recorded a total of 94 through the 12 years, allowing for an average of 8 (actual = 7.83) encounters per year. Wow! What happened? The actual question should be, “What didn’t happen, and why?” To answer the possible why of that situation, we need to look at the numbers of their prey base (lizards), while examining the results of other herps that rely on lizards as their primary prey base as well. At a miserable total of 144, the Zebra-tailed Lizard (Callisaurus draconoides) encounters hit rock bottom.

To put that number in perspective, in both 2001 and 2008, I saw more than that in one day! While lizard fluctuations are expected, a crash like this one is an eye-opening experience. Coupled with the fact that the Common Side-blotched Lizards (Uta stansburiana) encounters were down to their second lowest numbers of the century, the double crash is noteworthy. Their numbers are always the first thing that I go for when determining whether a year is good or bad in the herpetological sense. While I am grateful for the above average number of whiptails (Aspidoscelis sp.) seen, the knowledge that 146 of the total came from three trips to the east Rincon Mountains in July taints that picture. That leaves us with a total of 171 remaining for the rest of the year, which would fall more in line with what the numbers for the other species tell us. At an abysmal total of 21, the worst-ever column also embraces the Desert Spiny Lizards (Sceloporus magister). Only 21? Ouch! The slightly above average number of Regal Horned Lizards (Phrynosoma solare) is a good thing, but likely falls under the category “more luck than brains.” I found four on 9 July, and three more flat out

below average numbers. That number could have been much worse. During the month of May alone, 309 Ornate Tree Lizards (Urosaurus ornatus), and 68 whiptails were encountered in a canyon that I seldom visit. But such numbers as this are the reason why I add the “Total All” wildcards to my chart. The total number of 283 of “All Snakes” allows for the first above-average year since 2008. And the below-average number of “Total Both” of 1,666 puts the year of 2011 close to the middle of the 12 year period under discussion. In this regard, “Total Both” ranks in 7th place.

In March of 2001, Gordon Schuett and I joined forces to begin a radiotelemetry study on a smallish outlier hill that previously earned the name “Iron Mine Hill.” Neither of us ever dreamed that we would continue this study any longer than a couple of years. But 2011 brought about our tenyear anniversary. There have been but a few such studies with that sort of duration in the herpetological history of Arizona.

spectrum, we observed two full out acts of coitus, as well as a total of 14 pairings. We leave out much with discussion on efforts of both the herps and ourselves to stay alive in 2011 with this review. But in my mind, the most exciting event to happen at Iron Mine Hill was finding the secondever Mojave Rattlesnake (Crotalus scutulatus) there. The first was found in 2010. That one got off lightly. The one in 2011 year did not. In short, we gave this snake the gift that keeps on giving. We stuck a transmitter in him! When one is involved in investigating a patch of ground for 19 years, (this author has been visiting Iron Mine Hill since 1992), one often wonders, “What am I missing?” Was it possible that a population of C. scutulatus had gone unnoticed? By sticking a transmitter in this prime-of-life male, we hoped to find the answer to that question. For the first two weeks of tracking, he was a homeboy. He stayed close to his capture site. And then, he took off. Indeed, we lost him for a period of 2 weeks. When we found him again, he had traveled 2.6 miles (4.2 km) in a northwesterly direction. Then we lost him again. When we found him again, he was an astounding 3.6 miles (5.8 km) from his capture spot! It was here that he settled down. I thoroughly enjoyed the game of cat and mouse with this wayward snake. And the place that he led us is a patch of heaven on earth. The saguaros are tall and mighty, the hedgehog are knee high. The soil is absolutely pock-marked with small rodent burrows. We have to be careful where we trod, lest we fall through. It is a quiet and serene place, well off the beaten path. We see a future here, with the possibility of radio-tracking some more C. scutulatus, as well as C. atrox and, perhaps, some C. cerastes. Getting back to the original question, have we missed a population of C. scutulatus on our plot? If we can base our answer on our boy, the answer would be “no.” Here we had a male snake that made his big adventure, and he found us at the end of his road. I’ll bet that he can’t believe his good fortune! As we close the books on 2011, we have 5 venomous species of herp under scrutiny. We have 1 female Black-tailed Rattlesnake, 3 female Western Diamond-
backed Rattlesnakes, 2 male and 1 female Tiger Rattlesnakes, and our wayward male Mojave Rattlesnake. There is no other study in the state of Arizona with this sort of diversity that I know about. We earnestly look forward to beefing up some of our numbers in 2012, and seeing what we can learn about the ecological niche patterns of each. The Wrap Up—and Looking Ahead In review, 2011 was a below par herp year. The exceptional rainfall that we had from September through December did appear to do the landscape some good. At the date of this writing, (6 February 2012), the desert does have a verdant carpet of annuals sprouting. But the last rain that we had was on 16 January, and then two long-lasting high pressure areas have brought us delightfully warm, but very dry conditions. This is not good. What appears to be happening is the flowers are blooming prematurely. Without some sustained rains, we will wind up with bunches of tiny plants in full bloom. As the forecast shows no sign of rain in the near future, I foresee another drought ahead. Nevertheless, we wait in earnest for the spring egress of the herps under our watch. Time will tell what 2012 will give us. This author wishes to acknowledge 3 people by name. The first is David L. Hardy, Sr. Without him, there would not be a Tucson Herpetological Society. The second is Gordon W. Schuett, who saw fit to team up with a machine shop foreman to do a formal telemetry study on the animals we both love. Dianna L. Repp continues to be a wonderful spouse, who not only encourages my passion, but helps me with it. Last, but not least, I owe a huge debt of gratitude to those of you who have shared life’s greatest moments with me. I fear trying to name you all, lest I forget someone. So, whoever you all are, C’mon! Let’s do it again! This here is Roger Repp, signing off from Southern Arizona, where the turtles are strong, the snakes are handsome, and the lizards are all above average. Thanks for your indulgence.

Russell’s Viper (Daboia russelii; formerly Vipera russelii) was killed at a construction work site due to lack of awareness and widespread panic upon seeing the snake. The amount of venom produced by individual specimens is considerable. Reported venom yields for adult specimens range 0.0007-0.009 oz (21-268 mg). The species is not constrained to any particular habitat, but tends to avoid dense forests. The snake is frequently found in open, grassy, or bushy areas, but may also be found in second growth forests (scrub jungles), on forested plantations, and farmland. They are most common in plains, coastal lowlands, and hills of suitable habitat. Humid environments, such as marshes, swamps, and rain forests, are avoided. This adult Russell’s Viper (Daboia It feeds primarily on rodents. However, russelii; Shaw and Nodder 1797) was they will eat just about anything, includkilled by labors of a construction work site. The mass of the viper was ing rats, mice, shrews, squirrels, land crabs, 6.6 lbs (3 kg) and 5 feet (1.5 m) in scorpions, and other arthropods. Juveniles are length. Note the pattern on its skin: crepuscular, feeding on lizards and foraging brown patches bordered by deep actively. As they grow and become adults, they black circle. Some circles are also fused. Photos by Suman Pratihar. begin to specialize on rodents. To prevent further loss of wildlife, education programs are needed to bring awareness of and respect for our herpetofauna. Unnecessary eradication of reptiles and amphibians on the landscape by the actions of the human population has the potential to result in significant loss of biodiversity. With a little education, conservation of herpetfaunal species is possible.
Call for Proposals: Charles H. Lowe, Jr., Herpetological Research Fund
T he Charles H. Lowe, Jr., Herpetological Research Fund is accepting proposals to support research that
