Available in PDF, EPUB and Kindle. Book excerpt: “Authoritative and comprehensive—provides an up-to-date description of the tool box of methods for inventorying and monitoring the diverse spectrum of reptiles. All biodiversity scientists will want to have it during project planning and as study progresses. A must for field biologists, conservation planners, and biodiversity managers.”—Jay M. Savage, San Diego State University “Kudos to the editors and contributors to this book. From the perspective of a non-ecologist such as myself, who only occasionally needs to intensively sample a particular site or habitat, the quality and clarity of this book has been well worth the wait.”—Jack W. Sites, Jr.

Download or read book Behavioral and Metabolic Responses of Juvenile Spotted Salamanders Ambystoma Maculatum to Alarm Cues from Damaged Skin and Predator Diet written by Robert L. Hunt and published by . This book was released on 2011 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fitness can be maximized for individuals that are able to assess the level of predation risk and perform appropriate antipredator behaviors when predation risk is high. I investigated the ability of lab-reared juvenile spotted salamanders, Ambystoma maculatum, to assess predation risk via chemical alarm cues and substrate markings from predators fed different diets. In the alarm-cue experiment, salamanders avoided substrates marked with alarm cues but not from noninjured conspecifics or alarm stimuli from heterospecifics. Snakes that had recently consumed salamanders might represent a greater threat than snakes that had consumed other prey, but salamanders did not discriminate between markings of water snake predators fed different diets in any of the three experiments (i.e., no differences in avoidance, foraging or oxygen consumption). However, salamanders tended to avoid (P = 0.054) cues from water snakes regardless of diet and showed longer latencies to feed when exposed to chemical stimuli from snakes. Data for oxygen consumption are only preliminary due to low sample size; additional data are required before definitive conclusions can be made. Overall, chemical cues associated with predation risk are likely to play an important role in the ecology of post-metamorphic spotted salamanders.

This book was released on 2016 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Predator detection and assessment of predation risk have important survival consequences for animals. However, responses to predatory threats can vary with different stimuli. Chemical cues are important for predator recognition but visual cues may elicit defensive responses. Cottonmouths (Agkistrodon piscivorus) exhibit an array of antipredatory behaviors that have been thoroughly characterized in response to human aggressors, but their responses to cues from other predators are poorly known. I conducted three experiments to evaluate cottonmouth responses to visual and chemical stimuli from predators and non-predators. Snakes exposed to predator chemical cues exhibited elevated tongue-flick rates compared to controls but did not perform any antipredatory behaviors. Snakes exposed to mobile silhouettes of predators and nonpredators performed significantly more defensive displays in response to red-tailed hawk models than controls. However, snakes exposed to visual models of terrestrial predators and non-predators exhibited elevated responses to taxidermed mink and muskrat compared to an inanimate object of similar size and color. My results are consistent with risk-sensitivity predictions in that cottonmouths can use chemical cues to recognize predators and use visual cues to distinguish predatory bird silhouettes from those of nonpredatory birds. However, snakes generalized their antipredator responses to stationary mammals based on visual cues alone.
Download or read book Temperature Biology of Animals written by Andrew Cossins and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: Temperature is one facet in the mosaic of physical and biotic factors that describes the niche of an animal. Ofthe physical factors it is ecologically the most important. for it is a factor that is all-pervasive and one that. in most environments. lacks spatial or temporal constancy. Evolution has produced a wide variety of adaptive strategies and tactics to exploit or deal with this variable environmental factor. The ease with which temperature can be measured. and controlled experimentally. together with its widespread influence on the affairs of animals. has understandably led to a large. dispersed literature. In spite of this no recent book provides a comprehensive treatment of the biology of animals in relation to temperature. Our intention in writing this book was to fill that gap. We hope we have provided a modern statement with a critical synthesis of this diverse field. which will be suitable and stimulating for both advanced undergraduate and post graduate students of biology. This book is emphatically not intended as a monographical review. as thermal biology is such a diverse. developed discipline that it could not be encompassed within the confines of a book of this size.

Available in PDF, EPUB and Kindle. Book excerpt: The Fernow Watershed Acidification Study is a long-term, paired watershed acidification study. This book describes the responses to chronic N and S amendments by deciduous hardwood forests, one of the few studies to focus on hardwood forest ecosystems. Intensive monitoring of soil solution and stream chemistry, along with measurements of soil chemistry, and vegetation growth and chemistry, provide insights into the acidification process in forested watersheds.
