Reproductive Biology and Phylogeny of Lizards and Tuatara is a remarkable compendium of chapters written by the world's leading experts from over four continents. The book begins with a chapter recounting historical discoveries in reproductive biology and a review of phylogenetics and up-to-date hypotheses concerning evolutionary relationships amon

In clear, engaging prose, "Snakes" provides an up-to-date summary of every facet of the natural history of snakes--their diversity, evolution, and conservation--and, at the same time, makes a personal statement about why these animals are so compelling. 215 color photos. 3 tables.
This monograph addresses questions concerning the evolutionary history of advanced snakes using molecular phylogenetic data. Viperids are the sister group of the other clades examined. Atractaspis may share a lineage with elapids. The study concludes that, because of sampling problems, many generalizations concerning snake evolution derived from the fossil record, particularly those about the age of lineages, are probably in error.
While there are many more species of reptiles in the tropics than in temperate latitudes, relatively little is known about the natural history of tropical species of snakes. Even basic information, such as reproductive ecology and behavior, is lacking. Patterns of reproduction in tropical species differ from patterns in temperate species in important ways, such as the duration of gonadal activity and environmental factors that influence the frequency and timing of reproductive bouts. One tropical species, the brown tree snake (Boiga irregularis), was accidentally brought to the island of Guam and quickly became established throughout the island. Although this population has been monitored for over twenty years, many aspects of its basic biology, including its reproductive cycle, have yet to be described. The purpose of this dissertation research was to describe the reproductive biology and behavior of brown tree snakes on Guam. I used aggregation and shelter choice trials to determine whether females show aggregation behavior and to identify the cues that elicit aggregation. Reproductive state of the test snakes did not affect their response to the scent of a single male or female, but did change their response to multiple female scents. Measurements of gonad development and steroid hormones over a four-month period from captive snakes on Guam were compared to those obtained over the same time period from free-living snakes. Reproduction on Guam was found to be extended but seasonal, with females becoming vitellogenic in the latter part of the dry season and into the wet season. I also found that the corticosterone stress response did not vary with sex, size, or body condition, but the response of gonad sex hormones to acute stress was greater in larger snakes. I measured the body condition index and corticosterone levels of brown tree snakes on Guam to determine whether that population still showed the chronic stress and poor condition apparent in an earlier study. Significantly lower levels of corticosterone in all snakes in 2003 suggests that although juveniles did not have significantly improved energy stores they, along with mature males and females, were no longer under chronic levels of stress.
Snakes are creatures of mystery, arousing fear in many people but fascination in a few. Recent research has transformed our understanding of the behaviour and ecology of these animals, revealed their important roles in diverse ecosystems, and discovered new and effective ways to conserve their populations and to promote coexistence between snakes and people. One of the leading contributors to that scientific revolution has been Prof Rick Shine. Based in Australia, whose snake fauna is diverse and often dangerous, his experiences and anecdotes will inspire a new generation of serpent scientists. Spellbinding stories highlight the challenges, frustrations, and joys of discovery, and give the reader a greater appreciation of these often-slandered slithering reptiles. Key Features Documents the important role played by a preeminent herpetologist. Focuses on research conducted in Australia, especially on snakes. Summarizes highly influential conservation studies. Explores the ways in which research has deepened our understanding of snakes.
