Available in PDF, EPUB and Kindle. Book excerpt: "The Rock Rattlesnake (Crotalus lepidus) is a small-to-medium sized rattlesnake that inhibits [sic] the mountainous rocky areas of the United States in western Texas, southern New Mexico, and southeastern Arizona. It is highly variable, not only in color, but in pattern as well ... the purpose of this project is to provide, through the compilation of hundreds of photographs of 52 localities and over 240 snakes, as well as photos that date back over a quarter-of-a-century, the first complete summary of that noteworthy variability, but the very habitats they have adapted to. Basically, this is a book of eye-candy!"--P. 4.

Smith and published by . This book was released on 2013 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: In New Jersey, italicCrotalus horridusitalic, a state-endangered species, and italicPituophis melanoleucusitalic, a state-threatened species, are vulnerable to extirpation due to habitat loss and direct human impacts. I used radio-telemetry to determine the spatial ecology of these two species at the Warren Grove Range (WGR). italicCrotalus horridusitalic had no significant differences in home range size, seasonal activity, core activity area, range length, distance traveled per day, or seasonal differences in distance traveled per day between male and female snakes. They utilized hardwood swamp habitat the greatest proportion of use as compared to the six other habitat types identified at WGR. italicPituophis melanoleucusitalic had no significant differences in home range size, core activity area, range length, or distance traveled per day, between sexes or between locations in or outside of the target zone. italicPituophis melanoleucusitalic tracked in 2005 and 2006 traveled larger total distance, larger distance per day, and had larger home range compared to snakes in 2003 and 2004. There were no significant differences in maximum distance dispersed or location of hibernacula within home range by year or sex for italicP. melanoleucusitalic, which moved in all potential directions away from their hibernaculum, up to 2764.1 m away. A circular buffer around a hibernation site, based on dispersal distances, encompasses 2388 ha of land need to protect habitat and resources for the subpopulations of each hibernaculum. A minimum of 2388 ha, should be protected around hibernacula to support the current population of italicP. melanoleucusitalic. The WGR is an important location for snakes because the landscape is protected, relatively inaccessible, and free of negative impacts associated with urban development, agriculture, and high-use paved roadways. These data on the spatial ecology of these two snakes are important as baselines for evaluating threats to these snakes and can aid in developing mitigation and conservation strategies in light of the continued development in the Pine Barrens.

Download or read book Habitat Suitability and Selection of Northern Pacific Rattlesnakes Crotalus Oreganus Oreganus at Multiple Spatial Scales written by Lee Joseph Hecker and published by . This book was released on 2015 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Habitat modeling techniques are widely used to determine where species occur on the landscape and what habitat or environmental factors influence their presence. These techniques are particularly useful for rattlesnakes, which have life history traits that make them difficult to study in the field. Additionally, rattlesnakes like the northern Pacific rattlesnake (Crotalus oreganus oreganus) occupy a widespread and diverse range, making their environmental constraints difficult to determine. I used MaxEnt to create an environmental niche model (ENM) at two spatial scales to estimate where the suitable habitat for this species occurs in the Pacific Northwest and, more specifically, in coastal northern California. My results indicate selection for warmer habitats throughout the Pacific Northwest and drier environments within coastal northern California. I also examined the selection of a key aspect of the habitat of C. o. oreganus, the hibernaculum. I used a paired resource selection function to determine microhabitat differences between rocky outcrops used as hibernacula and outcrops that are visually similar, but unoccupied by the rattlesnakes. My top models reveal selection for outcrops with more crevices, fewer cover objects, and slopes facing due south (180° from North) for use as hibernacula. Additionally, temperatures loggers deployed at the hibernacula and their paired sites revealed that hibernacula are consistently warmer, particularly when rattlesnakes emerge in the spring. Lastly, I mapped the landslide activity within the vicinity of the hibernacula, which revealed a positive correlation between landslide presence and hibernacula. Combining these observations with the results of my models paint a comprehensive picture of where the suitable habitat for C. o. oreganus occurs in the Pacific Northwest.

Download or read book Snakes written by Stephen J. Mullin and published by Cornell University Press. This book was released on 2011-08-15 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
