Biology and Evolution of the Mexican Cavefish by Alex Keene,Masato Yoshizawa,Suzanne Elaine McGaugh Pdf

Biology and Evolution of the Mexican Cavefish features contributions by leading researchers in a comprehensive, unique work that examines a number of distinct areas of biology—evolution, development, ecology, and behavior—using the Mexican cavefish as a powerful model system to further understanding of basic biological processes such as eye degeneration, hearing, craniofacial development, sleep, and metabolic function. These fish are currently being used to better understand a number of issues related to human health, including age-related blindness, sleep, obesity, mood-related disorders, and aging. The recent sequencing of the cavefish genome broadens the interest of this system to groups working with diverse biological systems, and has helped researchers identify genes that regulate sleep, eye degeneration, and metabolic function. Mexican cavefish are particularly powerful for the study of biological processes because these fish evolved independently in twenty-nine caves in the Sierra de el Abra Region of Northeast Mexico. These fish have dramatic adaptations to the cave environment, and this can be used to identify genes involved in disease-related traits. This scholarly text will be of interest to researchers and students throughout diverse areas of biology and ecology. It includes photographs of animals and behavior in laboratory and natural settings that will also increase interest and accessibility to non-experts. Includes a mixture of images and illustrations such as the geographical distribution of cave pools and the developmental biology of the nervous system Features a companion site with geographical maps Fills a notable gap in the literature on a topic of broad interest to the scientific community Presents the recent sequencing of the cavefish genome as a groundbreaking development for researchers working with diverse biological systems

Evolution in the Dark by Horst Wilkens,Ulrike Strecker Pdf

This book provides fascinating insights into the development and genetics of evolutionary processes on the basis of animals living in the dark, such as the Astyanax cave fish. Biologically functionless traits show high variability, which results from neutral deleterious mutations no longer being eliminated by natural selection, which normally acts to preserve functional capability. These negative mutations accumulate until the traits they are responsible for become rudimentary or even lost. The random genetic basis of regressive evolution is in accordance with Nei’s Neutral Theory of Molecular Evolution, which applies to the molecular level. Such processes are particularly conspicuous in species living in constant darkness, where, for example in Astyanax, all traits depending on the exposure to light, like eyes, pigmentation, visually triggered aggressive behaviour, negative phototaxis, and several peripheral outcomes of circadian rhythmicity, are useless and diminish. In compensation constructive traits like taste, olfaction or the lateral line senses are improved by selection and do not show variability. Regressive and constructive traits inherit independently, proving that the rudimentation process is not driven by pleiotropic linkage between them. All these traits are subject to mosaic evolution and exhibit unproportional epistatic gene effects, which play an important role in evolutionary adaptation and improvement. Offering valuable evolutionary insights and supplemented by a wealth of illustrations, this book will appeal to evolutionary and developmental biologists alike.

The biology of hypogean fishes by Aldemaro Romero Pdf

Hypogean (cave, artesian) fishes have fascinated researchers even before they were described in the scientific literature in 1842. Since then, a number of scientists have used them to justify their own evolutionary ideas, from neo-Lamarckism to neo-Darwinism, from neutral evolution to selectionist approaches. Research in recent years has shown that these fishes are much more complex in their adaptations to the subterranean environment than previously believed: there are those with features expected from living in total darkness (complete blindness and depigmentation) and poor in nutrients (extremely low metabolic rates); others differ very little, if any, from their epigean (surface) ancestors in their morphology and physiology (but not so in their behavior). Some of them even live in nutrient-rich environments. Actually, one of the most overlooked facets of these animals is that there are more species of hypogean fishes without troglomorphisms (blindness, depigmentation) than with troglomorphic ones. The study of these apparently `unadapted' fishes is providing new insights into our understanding of the evolution of phenotypic characters, founding effect, behavioral, and physiological adaptations. The 86 species of troglomorphic fishes described so far belong to 18 different families, many of which would hardly fit the notion that they were 'preadapted' to conquer the underground environment. Further, many troglomorphic `species' show very little genotypic differentiation when compared with their putative ancestors, indicating that massive phenotype changes can be achieved via little genetic reorganization, a reorganization that mostly affects regulatory genes. These and many other topics are discussed in this volume containing 29 papers, written by 41 authors from 9 countries. Hopefully, this volume will convince many other researchers that hypogean fishes represent a unique opportunity to study a concept in evolutionary biology that is only superficially understood: convergent evolution.

Groundwater Ecology and Evolution by Florian Malard,Christian Griebler,Sylvie Retaux Pdf

Groundwater Ecology and Evolution, Second Edition is designed to meet a multitude of audience needs. The state of the art in the discipline is provided by the articulation of six sections. The first three sections successively carry the reader into the basic attributes of groundwater ecosystems (section 1), the drivers and patterns of biodiversity (section 2), and the roles of organisms in groundwater ecosystems (section 3). The next two sections are devoted to evolutionary processes driving the acquisition of subterranean biological traits (section 4) and the way these traits are differently expressed among groundwater organisms (section 5). Finally, section 6 shows how knowledge acquired among multiple research fields (sections 1 to 5) is used to manage groundwater biodiversity and ecosystem services in the face of future groundwater resource use scenarios. Emphasis on the coherence and prospects of the whole book is given in the introduction and conclusion. Provides a modern synthesis of research dedicated to the study of groundwater biodiversity and ecosystems Bridges the gap between community ecology, evolution, and functional ecology, three research fields that have long been presented isolated from each other Explains how this trans-disciplinary integration of research contributes to understanding and managing of groundwater ecosystem functions Reveals the contribution of groundwater ecology and evolution in solving scientific questions well beyond the frontiers of groundwater systems

Zebrafish, Medaka, and Other Small Fishes by Hiromi Hirata,Atsuo Iida Pdf

This book provides cutting-edge studies and technologies using small fishes, including zebrafish, medaka, and other fishes as new model animals for molecular biology, developmental biology, and medicine. It also introduces eccentric fish models that are pioneering new frontiers of biology. Zebrafish and medaka have been developed as lower vertebrate model organisms because these small fish are easy to raise in the laboratory and are useful for the live imaging of the morphology and activity of cells and tissues in intact animals. By virtue of those specific advantages, fish studies have demonstrated the common features of vertebrates and raised further questions toward understanding the mystery of life. The book consists of four parts: “Development and Cell Biology”, “Homeostasis and Reproduction”, “Clinical Models”, and “Eccentric Fish”. Together they describes the core area of small fish study – often considered mere zoology but which is actually proving to be the universal basis of life. Written by leading scientists, the book helps readers to understand small fishes, inspires scientists to utilize small fishes in their studies, and encourages anyone who wants to participate in the large and fantastic world of small fish.
