att completed his B.S. in Biological Science at the University of Vermont in 1992. After graduation Matt spent a summer as a research assistant on a small island in the Lesser Antilles studying the ecological and evolutionary aspects of lizard malaria in a population of Anolis lizards. In 1993 Matt came to Tucson to see the west and take herpetology in the desert. After a few months in town he was hired as a research technician in the University of Arizona’s Laboratory Molecular Systematics and Evolution. In this capacity Matt provided technical support and training to a wide assortment of researchers working on projects in the field of evolutionary genetics.
Number 14
After a year Matt entered the doctoral program in the Department of Ecology and Evolutionary Biology where he began his work on Sceloporus jarrovii that he will be discussing during the program. As a graduate research assistant to Dr. Michael Hammer, Matt worked on several research projects using the Y chromosome and mitochondrial DNA to investigate the population genetics and population history of human populations. In the fall of 1999 Matt started a collaborative project between the University of Arizona and Family Tree DNA in Dr. Hammer’s laboratory testing DNA for genealogical reconstruction. Over the following five years this project grew at a very rapid rate, testing tens of thousands of individuals. In April of 2005 Family Tree DNA and the University of Arizona teamed up to provide all of the public DNA testing for National Geographic and IBM’s Genographic Project. In 2010 when the work on the human DNA testing slowed, Matt shifted his focus back to his work on Sceloporus jarrovii and completed his doctorate this past December. Tonight Matt will share with us the findings of his doctoral dissertation, “Population structure of Yarrow’s Spiny Lizard, Sceloporus jarrovii, and its malarial parasite, Plasmodium chiricahuae.”

Book review
Life in Cold Lane: Hibernation in Anurans Howard O. Clark, Jr., Sonoran Herpetologist; editor.sonoran.herp@gmail.com Suman Pratihar and Jayanta Kumar Kundu; Paperback: 136 pages; $81.00. Publisher: LAP LAMBERT Academic Publishing (January 31, 2011); Language: English; ISBN-10: 3844303006; ISBN-13: 978-3844303001 Summary from Amazon.com: Amphibians watched the dinosaurs come and go, but today almost half of them are threatened with extinction. Amphibian species diversity is highest in the tropics. Hibernation is usually thought of as a resting condition in which an animal exists in a state of complete or partial torpidity. This is associated with low temperature. During this time animal’s dramatically slowing heart and breathing rates, lowering body temperature, going for long periods without eating. Biochemical and physiological parameters played a very crucial role during hibernation. Antioxidant activity, enzyme expression pattern, and RT-PCR analysis helped to understand the biology of hibernation.
Sducedumana publication Pratihar and Jayanta Kumar Kundu have prothat focuses on the hibernation of
anurans, with an overarching theme of global amphibian decline. The first part of the publication contains an assessment of possible and confirmed causes for amphibian decline, a comprehensive list of anuran species occurring in India, and another list specific to the West Midnapore region. The book’s focus species is the Indian Common Toad, Duttaphrynus melanostictus, and the authors provide a detailed species account to supplement the future chapters (see Pratihar and Kumar Kundu 2011). The next section details the biology of hibernation. Here, the authors provide a literature review and summary of what research has already been conducted on hibernating animals. Various terms are used to describe animals that go into a lower state of metabolism, including hibernation, aestivation, torpidity, and brumation. The authors explore these terms and provide relative definitions to allow the reader access to a full understanding of their differences and similarities. Following the hibernation section, the authors document the methods they used to study hibernation in the Indian Common Toad, including heartbeat recording, metabolic rate, blood urea, serum cholesterol, and white blood cell count. In all, thirty-six tests were conducted, demonstrating how complex hibernation actually is. Ten non-hibernating and ten hibernating toads (80-100 g) were tested. The remaining 11 chapters document the results of the tests with each chapter divided into these parts: introduction, animals tested, results and discussion. These 11 chapters are difficult to follow if the reader is not well versed in
physiology, cellular and molecular biology, biochemistry, and related fields. The final chapter is the conclusion section. Here, the authors summarize the entire volume into a comprehensive narrative. Some of the major conclusions are: • Heart rate, metabolic rate, and body weight of the hibernating toads decreased significantly during the hibernation period. • Significant seasonal variations in plasma protein, plasma glucose, and serum lipid profile were found in hibernating toads. • There is a strong link between elevated urea levels and cryoprotection during hibernation. • During hibernation the immunity of the toad was specifically antibody dependant. • Superoxide dismutase and catalase activities in liver and heart tissues significantly increased and glutathione activity was significantly reduced in response to the decreased temperature in hibernating toads.
Suman Pratihar and Jayanta Kumar Kundu have produced a publication that focuses on the hibernation of Anurans, with an overarching theme of global amphibian decline.
Overall the publication provides additional information regarding the hibernation of anurans, specifically the Common Indian Toad. One item that could have been expanded on is the relationship between hibernation in amphibians and amphibian declines. How does global climate change impact hibernating amphibians? How will hibernation and the associated physiology combat disease when the amphibians are vulnerable? Another chapter focusing on these and related questions would have been very helpful and is warranted in today’s rapid climate-focused world. Here are a few caveats regarding this review: the copy I received was a pre-press copy and some editing was still needed. Hopefully these errors were corrected prior to the volume going to press. In addition, the publication is not a book in the classic sense; it appears

to be a research thesis that was published in book form by the publisher, LAP LAMBERT Academic Publishing, which is known for publishing theses and dissertations for students. Amphibians are declining at an alarming rate and further research is needed to address these declines as they relate to a variety of factors, including: habitat destruction, alteration, and fragmentation; introduced species; over-exploition of natural resources; climate change; UV-B radiation; chemical contamination; disease; deformities; and synergisms. With the publication of this thesis, I hope other graduate students take the lead and discover ways to conserve our amphibian species. About the Authors Suman Pratihar, M.Sc., zoology (Gold Medelist), Vidyasagar University, is presently interested in the molecular aspects of metabolic depression in the hibernating anuran. Jayanta Kumar Kundu is an associate professor in zoology at Vidyasagar University. They have published 16 research articles (biochemistry and molecular biology) in peer-reviewed journals and 6 review articles (genome evolution). Literature cited Pratihar, S., and J.

Frequency of Reproduction in Female Western Diamond-backed Rattlesnakes from the Sonoran Desert of Arizona is Variable in Individuals: Potential Role of Rainfall and Prey Densities G. W. Schuett, R. A. Repp, and S. K. Hoss; Journal of Zoology; Volume 284, Issue 2, pages 105–113, June 2011
I
n many species of snakes, particularly viperids from temperate regions, production of offspring by individuals occurs on a less-than-annual schedule. Accordingly, acquiring sufficient energy and nutrient reserves for reproduction in females often requires more than a single active season. This is termed capital mode. Yet, in some instances, annual reproduction occurs under conditions where foraging success is high and environmental factors are compliant. This is termed income mode. Here, the authors addressed the hypothesis of annual versus less-than-annual reproduction from a long-term radio-telemetric study involving female Western Diamond-backed Rattlesnakes, Crotalus atrox, from a population in the Sonoran Desert in Arizona. From 2001 to 2008, 16 of 20 radio-telemetered females produced 36 litters, of which 32 were informative in addressing the hypothesis of reproductive frequency. In 14 females, litters were produced on a biennial or at-least-biennial (≥biennial) cycle. However,
seven females demonstrated annual reproduction, of which several had previously reproduced on a biennial or greater cycle. Because their study was non-experimental, they were unable to unambiguously identify specific proximate factors that contributed to the shift in annual reproduction. Nonetheless, they established that greater annual rainfall was significantly correlated with shifts to annual reproduction. Based on other studies, they hypothesize that increased rainfall was causally linked with increases in rodent densities and the foraging success of female C. atrox, which in turn is linked to reproduction. They describe several characteristics of female C. atrox that appear to facilitate the potential for annual reproduction. In long-lived species, such as C. atrox, their research underscores the necessity to follow individuals for extended periods to gain insights on reproductive cycles not captured by point sampling methods, such as short-term field studies or reliance on museum specimens.
