From the temptation of Eve to the venomous murder of the mighty Thor, the serpent appears throughout time and cultures as a figure of mischief and misery. The worldwide prominence of snakes in religion, myth, and folklore underscores our deep connection to the serpent—but why, when so few of us have firsthand experience? The surprising answer, this book suggests, lies in the singular impact of snakes on primate evolution. Predation pressure from snakes, Lynne Isbell tells us, is ultimately responsible for the superior vision and large brains of primates—and for a critical aspect of human evolution.
Drawing on extensive research, Isbell further speculates how snakes could have influenced the development of a distinctively human behavior: our ability to point for the purpose of directing attention. A social activity (no one points when alone) dependent on fast and accurate localization, pointing would have reduced deadly snake bites among our hominin ancestors. It might have also figured in later human behavior: snakes, this book eloquently argues, may well have given bipedal hominins, already equipped with a non-human primate communication system, the evolutionary nudge to point to communicate for social good, a critical step toward the evolution of language, and all that followed.
The Definitive Guide to Alabama’s Reptilian Wildlife.
Lizards and Snakes of Alabama is the most comprehensive taxonomy gathered since Robert H. Mount’s seminal 1975 volume on the reptiles and amphibians of Alabama. This richly illustrated guide provides an up-to-date summary of the taxonomy and life history of lizards and snakes native to, or introduced to, the state.
Alabama possesses one of the most species-rich biotas in north temperate areas and this richness is reflected in some groups of lizards, such as skinks, and especially in snakes. The authors examine all known species within the state and describe important regional variations in each species, including changes in species across the many habitats that comprise the state. Significant field studies, especially of Alabama’s threatened and endangered species, have been performed and are used to inform discussion of each account.
The life-history entry for each species is comprised of scientific and common names, full-color photographs, a morphological description, discussion of habits and life cycle, and a distribution map depicting the species range throughout the state, as well as notes on conservation and management practices. The illustrated taxonomic keys provided for families, genera, species, and subspecies are of particular value to herpetologists.
This extensive guide will serve as a single resource for understanding the rich natural history of Alabama by shedding light on an important component of that biodiversity. Accessible to all, this volume is valuable to both the professional herpetologist and the general reader interested in snakes and lizards.
In 2005 Kate Jackson ventured into the remote swamp forests of the northern Congo to collect reptiles and amphibians. Her camping equipment was rudimentary, her knowledge of Congolese customs even more so. She knew how to string a net and set a pitfall trap, but she never imagined the physical and cultural difficulties that awaited her.
Culled from the mud-spattered pages of her journals, Mean and Lowly Things reads like a fast-paced adventure story. It is Jackson’s unvarnished account of her research on the front lines of the global biodiversity crisis—coping with interminable delays in obtaining permits, learning to outrun advancing army ants, subsisting on a diet of Spam and manioc, and ultimately falling in love with the strangely beautiful flooded forest.
The reptile fauna of the Republic of Congo was all but undescribed, and Jackson’s mission was to carry out the most basic study of the amphibians and reptiles of the swamp forest: to create a simple list of the species that exist there—a crucial first step toward efforts to protect them. When the snakes evaded her carefully set traps, Jackson enlisted people from the villages to bring her specimens. She trained her guide to tag frogs and skinks and to fix them in formalin. As her expensive camera rusted and her Western soap melted, Jackson learned what it took to swim with the snakes—and that there’s a right way and a wrong way to get a baby cobra out of a bottle.
From the rare and docile massasauga, which relies on camouflage to remain unnoticed, to the more familiar bullsnake, which defends itself by hissing loudly and vibrating its tail from an S-shaped striking position, to the eastern racer, often seen crawling at more than three miles an hour during daytime, snakes are beautiful animals with habits both fascinating and beneficial to humans. Their relatives the lizards, most of which are more easily seen and identified, exhibit similarly fascinating behavior. This colorful addition to our series of laminated guides informs both amateur and professional herpetologists about twenty-seven species of snakes and six species of lizards in the Upper Midwest states of Minnesota, Wisconsin, Illinois, Indiana, Michigan, Ohio, South Dakota, North Dakota, Kansas, Nebraska, Iowa, and Missouri.
Terry VanDeWalle provides a complete description of each species, both adult and young, as well as distinguishing characteristics for thirty-two subspecies of snakes and two subspecies of lizards: length, color, head and neck patterns, scales, and so on. Also included is information about habitat preferences: forests, wet meadows, and sand prairies, for example. Most helpful for identifying snakes and lizards in the field are his comparisons of similar species and his comprehensive key.
Superb photographs by Suzanne Collins of adult and, when needed for identification, young snakes and lizards make this guide the perfect companion for hikers in all kinds of environments whenever a snake ripples across your path or a lizard darts into the underbrush.
