Download or read book Behavioral Ecology of the Eastern Red backed Salamander written by Robert G. Jaeger and published by Oxford University Press. This book was released on 2016-08-04 with total page 249 pages. 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.

Download or read book Epigenetic Mechanisms of the Cambrian Explosion written by Nelson R Cabej and published by Academic Press. This book was released on 2019-10-12 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Epigenetic Mechanisms of the Cambrian Explosion provides readers with a basic biological knowledge and epigenetic explanation of the biological puzzle of the Cambrian explosion, the unprecedented rapid diversification of animals that began 542 million years ago. During an evolutionarily instant of ~10 million years, which represents only 0.3% of the time of existence of life on Earth, or less than 2% of the time of existence of metazoans, all of the 30 extant body plans, major animal groups (phyla) and several extinct groups appeared. The work helps address this phenomena and tries to answer remaining questions for evolutionary biology, epigenetics, and scientific researchers. The book recognizes and presents objective representations of alternative theories for epigenetic evolution in this period, with the author drawing on his epigenetic theory of evolution to explain the causal basis of the Cambrian explosion. Both empirical evidence and theoretical arguments are presented in support of this thought-provoking epigenetic theory. - Explains the Cambrian explosion from an entirely epigenetic view - Takes a causal rather than descriptive approach to the phenomenon - Allows for a broad readership, including those with only a basic biological knowledge, while maintaining scientific rigor

Download or read book Epigenetic Principles of Evolution written by Nelson R Cabej and published by Elsevier. This book was released on 2011-11-22 with total page 847 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first and only book, so far, to deal with the causal basis of evolution from an epigenetic view. By revealing the epigenetic "user" of the "genetic toolkit", this book demonstrates the primacy of epigenetic mechanisms and epigenetic information in generating evolutionary novelties. The author convincingly supports his theory with a host of examples from the most varied fields of biology, by emphasizing changes in developmental pathways as the basic source of evolutionary change in metazoans. - Original and thought provoking--a radically new theory that overcomes the present difficulties of the theory of evolution - Is the first and only theory that uses epigenetic mechanisms and principles for explaining evolution of metazoans - Takes an integrative approach and shows a wide range of learning

Download or read book Hierarchical Modeling and Inference in Ecology written by J. Andrew Royle and published by Elsevier. This book was released on 2008-10-15 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: A guide to data collection, modeling and inference strategies for biological survey data using Bayesian and classical statistical methods.This book describes a general and flexible framework for modeling and inference in ecological systems based on hierarchical models, with a strict focus on the use of probability models and parametric inference. Hierarchical models represent a paradigm shift in the application of statistics to ecological inference problems because they combine explicit models of ecological system structure or dynamics with models of how ecological systems are observed. The principles of hierarchical modeling are developed and applied to problems in population, metapopulation, community, and metacommunity systems. The book provides the first synthetic treatment of many recent methodological advances in ecological modeling and unifies disparate methods and procedures.The authors apply principles of hierarchical modeling to ecological problems, including * occurrence or occupancy models for estimating species distribution* abundance models based on many sampling protocols, including distance sampling* capture-recapture models with individual effects* spatial capture-recapture models based on camera trapping and related methods* population and metapopulation dynamic models* models of biodiversity, community structure and dynamics - Wide variety of examples involving many taxa (birds, amphibians, mammals, insects, plants) - Development of classical, likelihood-based procedures for inference, as well as Bayesian methods of analysis - Detailed explanations describing the implementation of hierarchical models using freely available software such as R and WinBUGS - Computing support in technical appendices in an online companion web site

Download or read book Neuroendocrine Regulation of Animal Vocalization written by Cheryl S. Rosenfeld and published by Academic Press. This book was released on 2020-12-04 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neuroendocrine Regulation of Animal Vocalization: Mechanisms and Anthropogenic Factors in Animal Communication examines the underpinning neuroendocrine (NE) mechanisms that drive animal communication across taxa. Written by international subject experts, the book focuses on the importance of animal communication in survival and reproduction at an individual and species level, and the impact that increased production and accumulation of endocrine-disrupting chemicals (EDCs) can have on these regulatory processes. This book discusses sound production, perception, processing, and response across a range of animals. This includes insects, fish, bats, birds, nonhuman primates, infant humans, and many others. Some chapters analyze how neuroactive substances, endocrine control, and chemical pollution affect the physiology of the animal's perceptive and sound-producing organs, as well as their auditory and vocal receptors and pathways. Other chapters address the recent approaches governments have taken to protect against the endocrine disruption of animal (vocal) behaviors. The book is a valuable resource for researchers and advanced students seeking first-rate material on neuroendocrinological effects on animal behavior and communication. - Serves as the most comprehensive cross-taxa study of its kind, revolutionary in its focus on the impacts of EDCs on the processes guiding animal communication - Emphasizes the importance of production, perception and processing of acoustic vocalization for survival - Analyzes recent governmental policies and protections against the effects of EDCs on humans and wildlife
