Excerpt from Systematic and Ecological Relationships of the Water Snakes Natrix Sipedon and N. Fasciata in Alabama and the Florida Panhandle It has been reported that the range of pleuralis overlaps that of confluens throughout part of the Mississippi River Valley (rhoads, 1895z376; Parker, -85; Woodman, Clay (1936 218) could find no Specimens intermediate between the two forms, but postulated that they do occur. Woodman stated that there was no evidence of intergradation between pleuralis and con fluens in the highlands of Arkansas, although both were collected in the same river on the same day; however, only two specimens, one of each, were taken from the river. Smith (1961z261) suggested confluens influence in occasional specimens of pleuralis from south ern Illinois. He noted that no specimens had been examined which were not clearly referable to either pleuralis or confluens. Anderson (1965 151) noted that the two forms appear to be ecologically sepa rated in Missouri. Barbour stated that confluens was found only in extreme southwestern Kentucky and that it preferred large shallow bodies of water. He noted that pleuralis occurs in southwestern Kentucky, but prefers flowing water. Webb 271) indicated an overlap in. The ranges of pleuralis and confluens in Oklahoma. Gordon reported pleuralis in the same drainage with confluens and N. F. Fasciata. Neill (1946z256, 1954z85) also found pleuralis within the range Of N. F. Fasciata in Alabama, the Florida Panhandle, and Georgia. Neither of these workers found intermediates between the forms in question. Gordon suggested that future studies might reveal distinct habitat differences which per mit overlapping of the range.

Many people fear snakes, and watersnakes in particular have one of the worst reputations of any snake found in North America. Some species are commonly mistaken for venomous cottonmouths, and a few may eat popular game fishes. Unfortunately, few people realize the important roles many watersnakes play in natural ecosystems and, consequently, they are still persecuted in many regions today. Seeking to overcome common misperceptions, J. Whitfield Gibbons and Michael E. Dorcas have compiled North American Watersnakes, the first comprehensive study of all fourteen species of watersnakes found in the United States, Canada, Mexico, and Cuba. Individual species accounts explore all aspects of the natural history of watersnakes in North America, including their behavior, physiology, life history, ecology, and conservation. Almost 100 color photographs accompany the text, illustrating all 14 species and nearly all subspecies. Supplementing the species accounts are detailed color maps depicting each species distribution and stunning black-and-white drawings by Peri Mason. Easy-to-use keys help readers to identify specimens at hand.

Destruction of habitat due to urban sprawl, pollution, and deforestation has caused population declines or even extinction of many of the world's approximately 2,600 snake species. Furthermore, misconceptions about snakes have made them among the most persecuted of all animals, despite the fact that less than a quarter of all species are venomous and most species are beneficial because they control rodent pests. It has become increasingly urgent, therefore, to develop viable conservation strategies for snakes and to investigate their importance as monitors of ecosystem health and indicators of habitat sustainability. In the first book on snakes written with a focus on conservation, editors Stephen J. Mullin and Richard A. Seigel bring together leading herpetologists to review and synthesize the ecology, conservation, and management of snakes worldwide. These experts report on advances in current research and summarize the primary literature, presenting the most important concepts and techniques in snake ecology and conservation. The common thread of conservation unites the twelve chapters, each of which addresses a major subdiscipline within snake ecology. Applied topics such as methods and modeling and strategies such as captive rearing and translocation are also covered. Each chapter provides an essential framework and indicates specific directions for future research, making this a critical reference for anyone interested in vertebrate conservation generally or for anyone implementing conservation and management policies concerning snake populations.
