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.

Available in PDF, EPUB and Kindle. Book excerpt: Visual communication contributes to speciation through sexual selection in numerous, distantly related taxa. Sexual selection favors signals that are conspicuous to the intended receiver. The diverse African cichlid fishes offer a rich opportunity for investigating diversification. Although male cichlids appear conspicuous to the human eye, the spectral sensitivity and photic environment of cichlids differ from ours. In my dissertation I investigate cichlid color signals and the sensitivities of the retinas receiving these signals. First I ask whether male colors appear more conspicuous than female colors to cichlids in their environment. I use simple models of cichlid color space to compare cichlid colors and backgrounds that I measure with a spectrometer. Results indicate male colors are typically more conspicuous than female colors, consistent with the selective forces thought to act on each sex. However, in some species female colors are conspicuous, highlighting the need for further study of cichlid behavior. To facilitate analysis of numerous colors and backgrounds, the models assume cichlids are trichromatic. However, cichlid sensitivity may be more complex. Cichlids are known to express up to eight different opsin proteins in one retina, and this expression is influenced by the rearing light environment. Opsins help determine the spectral sensitivity of the photoreceptors in which they reside, yet their distribution in cichlid retinas is unknown. Using in situ hybridization and microspectrophotometry, I show that the cichlid Metriaclima zebra mixes different pairs of opsins in retinal regions that view distinct backgrounds. Opsin mixing increases sensitivity to the corresponding backgrounds, potentially aiding detection of dark objects. This is the first documentation of spectral tuning by opsin coexpression. However, my calculations show that coexpression of some opsins can hinder color discrimination, creating a trade-off between visual functions. By rearing M. zebra in different light conditions I found that the location as well as the relative proportion of opsins in the retina can be influenced by the environment. This suggests that developmental plasticity of opsin expression may contribute to the spectral tuning of retinal regions. Cichlids demonstrate that retinal sensitivity can be spatially heterogeneous and plastic and may affect signal evolution in undocumented ways.

Download or read book The Cichlid Fishes written by George Barlow and published by Basic Books. This book was released on 2008-12-15 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cichlid fishes are amazing creatures. In terms of sheer number of species, they are the most successful of all families of vertebrate animals, and the extent and speed with which they have evolved in some African lakes has made them the darlings of evolutionary biologists. But what truly captivates biologists like George Barlow -- not to mention thousands of aquarists the world over -- is the complexity of their social lives and their devotion to family (most species of cichlids are monogamous and many pairs share the responsibility of raising offspring). In this wonderful book, Barlow describes the unusually high intelligence of these fishes, their complex mating and parenting rituals, their bizarre feeding and fighting habits, and the unusual adaptations and explosive rate of speciation that have enabled them to proliferate and flourish. A celebration of their diversity, The Cichlid Fishes is also a marvelous exploration of how these unique animals might help resolve the age-old puzzle of how species arise and evolve.

Available in PDF, EPUB and Kindle. Book excerpt: The Lateral Line System provides an overview of the key concepts and issues surrounding the development, evolution, neurobiology, and function of the lateral line, a fascinating yet somewhat enigmatic flow-sensing system. The book examines the historical precedence for linking the auditory and lateral line systems, its structure and development, use of the lateral line system of zebrafish as a model system, physical principles governing the response properties of the lateral line, the behavioral relevance of this sensory system to the lives of fish, and an examination of how this information is shaped and encoded by the peripheral and central nervous systems.
