Book Description
This book is the monograph of the eastern diamondback rattlesnake by D. Bruce Means. Its publication is a culmination of over 40 years of long-term, in-depth study of the world's largest rattlesnake, Crotalus adamanteus. In the preface Means writes, "The limited biological knowledge available for this species is all the more amazing when one considers the economic impact of Crotalus adamanteus. Because of its large size and highly toxic venom, it is arguably the most dangerous venomous snake in the United States and Canada, accounting for more human mortality than any other species (Klauber 1972; Parrish 1980). Its ecological importance may be even more significant, however. The eastern diamondback is a major predator of the cotton rat (Sigmodon hispidus), a significant crop pest that is probably the most abundant rodent in the southeastern United States (Lowery 1974). Moreover, the eastern diamondback, which weighs up to about thirteen pounds (5.9 kilograms), is the largest cold-blooded terrestrial vertebrate living in the temperate zones of the earth (Means 1985)."

Book Description
The aim of this project was to analyze relationships among populations of Crotalus adamanteus (Eastern Diamondback Rattlesnake) and to compare phylogeographic patterns across different classes of genes. The objective was to determine the effect of selective pressures on the detection of barriers to gene flow. For example, venom genes are under strong positive selection and allow an analysis of the rate of allele exchange in a gene that directly affects the fitness of an individual. This selection might drive alleles through phylogeographic barriers that limit the spread of neutral alleles. The relationship between nontoxin genes and fitness is not as clear and can be difficult to establish. However, most variation in these genes is neutral and determined by stochastic events. The type of selection on a gene will affect the phylogeographic pattern displayed. Prior phylogeographic studies have used either neutral markers (e.g., microsatellites) or genes not directly involved in specific adaptations (e.g., mitochondrial genes). One venom gene, two mitochondrial genes, one nuclear gene, and one pseudogene were compared for patterns of adaptation and the presence of geographic barriers to gene flow. This novel approach to studying gene flow could have an impact on defining taxonomic groups and conservation efforts, as well as serve as a guide for choosing appropriate genetic markers for other species. In the venom gene that was analyzed, it appeared the high level of selection led to alleles being driven across the barriers to gene flow of alleles under neutral selection.

Book Description
The ominous rattle of the timber rattlesnake is a chilling shorthand for imminent danger, and a reminder of the countless ways that nature can suddenly snuff us out. Though they're found in thirty-one states, and near many major cities, in contemporary America timber rattlesnakes are creatures mostly of imagination and innate fear. Levin takes us from labs where the secrets of the snake's evolutionary history are being unlocked to far-flung habitats to explore the painful struggles involved in protecting and preserving its natural world.
