Book Synopsis Visual Behavior in Salamanders by : Professor of Zoology/Director of Brain Research Institute Gerhard Roth
Download or read book Visual Behavior in Salamanders written by Professor of Zoology/Director of Brain Research Institute Gerhard Roth. This book was released on 1987-08-18. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with vision and visually guided behavior in salamanders, with special emphasis on feeding behavior. The underlying neural mechanisms, functional morphology, as well as ecological and evolutionary aspects of salamander behavior are studied. The extensive data comprises experiments on visually guided behavior, the influence of learning and imprinting on feeding behavior, the anatomy of the salamander eye and brain, and the morphology and development of the visual and visiomotor centers. This book also presents mechanisms and models of processing visual information within the salamander eye and brain, of object recognition, depth perception and sensory-motor interface problems in amphibians. This book will be invaluable to all scientists working on visually guided behavior, amphibian neurophysiology and ecologically induced behavior.

Book Synopsis Visual Behavior in Salamanders by : Gerhard Roth
Download or read book Visual Behavior in Salamanders written by Gerhard Roth. This book was released on 2012-12-06. Available in PDF, EPUB and Kindle. Book excerpt: Salamanders are subject to misconceptions even among vertebrate zoologists and physiologists. They are often said to exist only in northern temperate zones, being bound to aquatic or very moist cool habitats. In reality, more than half of all salamander species live in subtropical and tropical zones, ex clusively in the New World. Again, more than half of the salamand~r species have become totally independent of aquatic habitats following the loss of a free larval stage. Many of the subtropical and tropical salamanders have become adapted to rather high temperatures up to 26-28 DC. The brain and the sensory systems of salamanders are often considered to be primitive, and their behavior is thought to be simple and uninfluenced by learning. However, careful studies show that the salamander brain possesses virtually all the ana tomical and functional properties found in anurans, which are usually regarded as being much more evolved with respect to the guidance of comparable behavior. Most of the salamander species not only possess a highly efficient visual system, which is the topic of the present work, but can orient themselves almost as effectively by means of olfaction, vibration sense, and electroreception. Furthermore, it has recently been shown that at least part of their behavior, especially that concerned with feeding and prey preferences, is strongly influenced by individual experience.

Book Synopsis Behavioral Ecology of the Eastern Red-backed Salamander by : Robert G. Jaeger
Download or read book Behavioral Ecology of the Eastern Red-backed Salamander written by Robert G. Jaeger. This book was released on 2016-08-04. Available in PDF, EPUB and Kindle. Book excerpt: The small, terrestrial eastern red-backed salamander is abundant on many forest floors of northeastern North America. Dr. Robert Jaeger and many of his graduate students spent over 50 years studying this species in New York and Virginia, using ecological techniques in forests and behavioral experiments in laboratory chambers in an attempt to understand how this species interacts with other species in the forest and the components of its intra- and intersexual social behaviors. The competitive and social behaviors of this species are unusually complex for an amphibian. This species is highly aggressive towards other similar-size species where they cohabit in forests, often leading to very little geographic overlap between the species. The authors examine the fascinating behavioral traits of this species including social monogamy, mutual mate guarding, sexual coercion, inter-species communication, and conflict resolution.

Book excerpt: In Waterton Lakes National Park, located in southwest Alberta, Canada, under-road crossing structures were installed in 2008 to protect a population of long-toed salamander (Ambystoma macrodactylum) at Linnet Lake from mortality during breeding migrations that intersected with the park's entrance road. This compilation first investigates orientation and movement patterns of marked individuals at Linnet Lake in 2013 and 2014, and at a smaller, shallower wetland Stable Pond in 2014 to document in detail how long-toed salamanders used the terrestrial landscape around breeding sites during adult migration and juvenile dispersal. Following this, the authors use generalized linear models to model salamander occurrence and abundance in the Beaver Hills region of north-central Alberta as a function of land cover type and pocket gopher density. The authors go on to address whether any ecological barriers exist in the distribution range of the two newt species N. strauchii and N. crocatus. According to the findings of this study, an identity test was found to be significantly different from the null distribution, whereas a background test was not significantly different from the null distribution. The concluding chapter summarizes the processes by which light is converted into neural signals by rods and cones and then transmitted to downstream neurons in the retina, with a focus on salamander photoreceptors. The different types of photoreceptor cells and other light-sensitive cells in salamanders and their role in vision are also discussed.
