Available in PDF, EPUB and Kindle. Book excerpt: This book comprehensively summarizes the biological mechanisms of coloration and pattern formation of animals at molecular and cellular level, offering up-to-date knowledge derived from remarkable progress in the last 10 years. The brilliant coloration, conspicuous patterns and spectacular color changes displayed by some vertebrates and invertebrates are generally their strategies of the utmost importance for survival. Consists of mainly three parts, starts with introductory chapter, such as Pigments and Pigment Organelles, Developmental Genetics of Pigment Cell Formation, Adult Pigment Patterns, and Color Changes, this book introduces new pigment compounds in addition to classically known pigments and organelles, explains how the generation of multiple types of pigment cell is genetically controlled, describes the mechanisms underlying the zebrafish stripe formation as well as other animals and also summarizes the mechanism of physiological and morphological color changes of teleost, amphibian and cephalopod. Written by experts in the field, this book will be essential reading for graduate students and researchers in biological fields who are interested in pigmentation mechanisms of animals.

Download or read book Body Size Evolution and Diversity of Fishes Using the Neotropical Cichlids Cichlinae as a Model System written by Sarah Elizabeth Steele and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The influence of body size on an organism's physiology, morphology, ecology, and life history has been considered one of the most fundamental relationships in ecology and evolution. The ray-finned fishes are a highly diverse group of vertebrates. Yet, our understanding of diversification in this group is incomplete, and the role of body size in creating this diversity is largely unknown. I examined body size in Neotropical cichlids (Cichlinae) to elucidate the large- and small-scale factors affecting body size diversity and distribution, and how body size shapes species, morphological, and ecological diversity in fishes. Characterization of body size distributions across the phylogeny of Neotropical cichlids revealed considerable overlap in body size, particularly in intermediate-sized fishes, with few, species-poor lineages exhibiting extreme body size. Three potential peaks of adaptive evolution in body size were identified within Cichlinae. I found freshwater fishes globally tend to be smaller and their distributions more diverse and right-skewed than marine counterparts, irrespective of taxonomy and clade age, with a strengthening of these trends in riverine systems. Comparisons of Neotropical cichlid body size diversity and distribution to this broader context shows that body size patterns are largely abnormal compared to most freshwater fishes, particularly those of the Neotropics. This implies that small body size is rarer in Cichlinae, despite several independent cases of body size decrease in this lineage. I found that these small-bodied lineages are miniaturized cichlids, exhibiting strong reduction in body size, as well as paedomorphic characters and ontogenetic truncation compared to their sister taxa. Further examination of ontogenies across Neotropical cichlids found considerable shape conservatism over ontogeny and phylogeny, with cichlids following similar ontogenetic trajectories. Therefore, ontogenetic pathways do not contribute considerably to morphological divergence seen in adults, with divergence likely occurring in the larval stage or perhaps during embryology. The evolution of ontogeny, body size, and shape did not correspond to a unique adaptive peak in miniatures, or three body size optima predicted from the distribution of size across the phylogeny. Rather, it is complex and, like early trait divergence previously seen, diversifies early in the phylogeny across the major lineages of Neotropical cichlids.

Download or read book Historical Biogeography of Neotropical Freshwater Fishes written by James S. Albert and published by Univ of California Press. This book was released on 2011-03-08 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fish faunas of continental South and Central America constitute one of the greatest concentrations of aquatic diversity on Earth, consisting of about 10 percent of all living vertebrate species. Historical Biogeography of Neotropical Freshwater Fishes explores the evolutionary origins of this unique ecosystem. The chapters address central themes in the study of tropical biodiversity: why is the Amazon basin home to so many distinct evolutionary lineages? What roles do ecological specialization, speciation, and extinction play in the formation of regional assemblages? How do dispersal barriers contribute to isolation and diversification? Focusing on whole faunas rather than individual taxonomic groups, this volume shows that the area’s high regional diversity is not the result of recent diversification in lowland tropical rainforests. Rather, it is the product of species accumulating over tens of millions of years and across a continental arena.

Available in PDF, EPUB and Kindle. Book excerpt: This volume constitutes the most recent and most comprehensive consideration of the largest family of bony fishes, the Cichlidae. This book offers an integrated perspective of cichlid fishes ranging from conservation of threatened species to management of cichlids as invasive species themselves. Long-standing models of taxonomy and systematics are subjected to the most recent applications and interpretations of molecular evidence and multivariate analyses; and cichlid adaptive radiations at different scales are elucidated. The incredible diversity of endemic cichlid species in African lakes is revisited as possible examples of sympatric speciation and as serious cases for management in complex anthropogenic environments. Extreme hydrology and bathymetry as driver of micro-allopatric speciation is explored in the African riverine hotspot of diversity of the lower Congo River. Dramatic new molecular evidence draws attention to the complex taxonomy and systematics of Neotropical cichlids including the crater lakes of Central America. Molecular genetics, genomics, imaging tools and field study techniques assess the roles of natural, sexual and kin selection in shaping cichlid traits and beyond. The complex behavioral adaptations of cichlids are considered from a number of sub-disciplines including sensory biology, neurobiology, development, and evolutionary ecology. Most importantly, this volume puts forth a wealth of new interpretations, explanatory hypotheses and proposals for practical management and applications that will shape the future for these remarkable fishes in nature as well as their use as models for the study of biology.
