Download or read book Hormones and Reproduction of Vertebrates written by David O. Norris and published by Academic Press. This book was released on 2010-11-25 with total page 1681 pages. Available in PDF, EPUB and Kindle. Book excerpt: This series of volumes represents a comprehensive and integrated treatment of reproduction in vertebrates from fishes of all sorts through mammals. It is designed to provide a readable, coordinated description of reproductive basics in each group of vertebrates as well as an introduction to the latest trends in reproductive research and our understanding of reproductive events. Whereas each chapter and each volume is intended to stand alone as a review of that topic or vertebrate group, respectively, the volumes are prepared so as to provide a thorough topical treatment across the vertebrates. Terminology has been standardized across the volumes to reduce confusion where multiple names exist in the literature, and a comprehensive glossary of these terms and their alternative names is provided. A complete, essential and up to date reference for research scientists working on vertebrate hormones and reproduction - and on animlals as models in human reproductive research Covers the endocrinology, neuroendocrinology, physiology, behaviour and anatomy of vertebrate reproduction Structured coverage of the major themes for all five vertebrate groups allows a consistent treatment for all Special chapters elaborate on features specific to individual vertebrate groups and to comparative aspects, similarities and differences between them

This book was released on 2023-07-25 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: Temperature plays a critical role in animal survival and climate warming is one of the greatest threats to global biodiversity in the future. It is already affecting species and communities with severe impacts and it is predicted that climate warming will cause species extinctions and distributional shifts in the coming decades. The impact of climate warming is expected to be particularly severe on ectothermic animals, including fishes, amphibians, and reptiles. Thus, assessing species’ responses to ongoing climate warming and determining what conservation actions should be taken are among the most significant and controversial challenges for ecologists. Identifying the most vulnerable species to extinction as a result of climate warming is an appropriate first step in mitigating the impacts of a changing world. An organism’s vulnerability to climate warming depends on its sensitivity to environmental changes, its exposure to the change, and its ability to recover from and potential to adapt to change. The interaction of these factors makes predicting the effects of climate warming on species a complex and major challenge for ecologists. Developing a deeper knowledge of ectotherms’ vulnerability to climate warming is crucial to enhance our understanding of extinction processes and significantly contribute to conservation efforts by guiding the implementation of better policies and management strategies to prevent the extinction of remaining populations. Investigations of climate warming vulnerability are likely to benefit from measurements of environmental conditions taken at the scale at which organisms experience them. Therefore, the main objective of this interdisciplinary Research Topic is to bring together research on how ectotherms respond to climate warming at various levels. We will particularly focus on the life-history, energy strategy, physiological response, etc. We encourage inter-and multidisciplinary research approaches linking molecular biology, thermal physiology (and ecology), behavioral ecology, functional ecology, evolutionary genetics, and bioenergetics.

Download or read book Choosing Sexes written by Kristen J. Navara and published by Springer. This book was released on 2018-02-01 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is extensive evidence that vertebrates of all classes have the ability to control the sexes of the offspring they produce. Despite dramatic differences in the mechanisms by which different taxa determine the initial sex of offspring, each group has found its own way of adjusting offspring sex ratios in response to social and environmental cues. For example, stress is a well-known modulator of offspring sex in members of all groups studied to date. Food availability, and limitation in particular, is another common cue that stimulates biases in offspring sex ratios in a wide variety of species. Offspring sex can be adjusted at the primary level, which occurs prior to conception, or at the secondary level, during embryonic development. While the mechanistic pathways that ultimately result in sex ratio biases and the developmental time-points sensitive to those mechanisms likely differ among taxa, the key involvement of steroid hormones in the process of sex ratio adjustment appears to be pervasive throughout. This book reviews the systems of sex determination at play in different vertebrate groups, summarizes the evidence that members of all vertebrate taxa can facultatively adjust offspring sex, and discusses when and how these adjustments can take place.

Book excerpt: Begins with an overview of amphibians and reptiles as organisms, explaining their roles in modern ecosystems, and progressively builds an appreciation of these animals as diverse and successful organisms, emphasizing the common challenges the face and the diversity of responses they have evolved. Considers the phylogenetic relationships of amphibians, examines gametogenesis and reproductive cycles, discusses their communication methods, and talks about the impact we have had on them through environmental pollution, commercial exploitation, and more.
