Co Thologie De La Reproduction Des Poissons

La formation des couples et la sélection sexuelle, l'accouplement et la ponte, les soins parentaux. Une subtile biologie de la sexualité et des comportements reproductifs d'une remarquable diversité, parmi les plus variés de tous les vertébrés. Bien que leurs mécanismes génétiques et leurs processus physiologiques soient communs à tous les vertébrés, les poissons se singularisent par d'étonnantes capacités à mettre en œuvre des tactiques et des stratégies reproductives convenablement adaptées aux variations spatiales et temporelles de leur environnement aquatique et aux fluctuations de leurs relations sociales. Une telle "inventivité" leur a permis de traverser jusqu'à nous les diverses ères géologiques, quelles qu'aient été les conditions environnementales, et d'occuper, de nos jours, tous les systèmes aquatiques. Éco-éthologie de la reproduction des poissons fait le point sur l'état des connaissances actuelles relatives à la biologie, à l'écologie et à l'éthologie de la reproduction, à la lumière des travaux les plus récents, réalisés, à la fois, par des observations en milieu naturel et en conditions expérimentales de laboratoire. Il permettra au lecteur de se persuader que, loin d'être des vertébrés "inférieurs" comme le présuppose leur position dans la "systématique" du règne animal, les poissons sont des organismes dont de nombreux comportements reproductifs peuvent être fort complexes, à l'image de ceux des anguilles, des saumons, des bouvières, des amphiprions. Cet ouvrage est destiné aux enseignants et étudiants de 2e et 3e cycles en biologie, écologie, éthologie, hydrobiologie, environnement, ainsi qu'aux ingénieurs et techniciens chargés de l'aménagement et de la protection des milieux naturels. Il sera également d'un grand intérêt pour les responsables des aquariums publics et les aquariophiles, les aquaculteurs, les pêcheurs et les écologistes.

The interactions between wild bird populations (many protected by law) and fish, particularly those under commercial culture or part of a fishery is subject of much controversy. Ecological, environmental and conservation pressures run alongside commercial pressures on exploited fish populations. This exciting book draws together contributions from all over the world to provide a fascinating insight into many case studies and conflicts in managed situations as well as looking at the overall ecology of such interactions in normal un-managed ecosystems.

Intertidal Fishes describes the fishes inhabiting the narrow strip of habitat between the high and low tide marks along the rocky coastlines of the world. It analyzes the specialized traits of these fishes that have adapted to living in the dynamic and challenging space where they are alternately exposed to the air and submerged in water with the ebb and flow of the tides. This book provides a comprehensive account of fishes largely overlooked in many previous studies of intertidal organisms and emphasizes how they differ from fishes living in other deeper-water habitats. Coverage includes air breathing, movements and homing, sensory systems, spawning and parental care, feeding habits, community structure, systematic relationships, distribution patterns, and the fossil record in the intertidal zone. Written by an international team of 21 experts on intertidal fish biology Worldwide coverage of intertidal fishes Comprehensive phylogenetic listing of all fish families with intertidal members Global biogeographic analysis involving over 700 species from 86 sites Outlines field and laboratory methods pertinent to studying intertidal fishes Thorough ecological coverage with chapters on vertical distribution, movements and homing, reproduction, feeding, and community structure Covers the physiology of aerial and aquatic respiration, osmoregulation, and sensory systems

Sea urchins are a major component of the world ocean. They are important ecologically and often greatly affect marine communities. They have an excellent fossil record and consequently are of interest to paleontologists. Research has increased in recent years stimulated first by a recognition of their ecological importance and then because of their economic importance. Scientists around the world are actively investigating their potential for aquaculture. This book is designed to provide a broad understanding of the biology and ecology of sea urchins. Synthetic chapters consider biology of sea urchins as a whole to give a broad view. The topics of these chapters include reproduction, metabolism, endocrinology, larval ecology, growth, digestion, carotenoids, disease and nutrition. Subsequent chapters consider the ecology of individual species that are of major importance ecologically and economically. These include species from Japan, New Zealand, Australia, Europe, North America, South America and Africa. * First comprehensive book devoted to the biology and ecology of sea urchins * NEW chapter on Nutrition of Sea Urchins and Ecology of Diadema * Brand NEW illustrations * Hot NEW topic: Immunology of the Sea Urchin * Chapters written by internationally recognized experts * Each chapter revised and updated from the first edition * Biological chapters include reproduction, endocrinology, carotenoids and disease * Ecological chapters include species of major economic interest for fisheries and aquaculture

Vols. for 1871-76, 1913-14 include an extra number, The Christmas bookseller, separately paged and not included in the consecutive numbering of the regular series.
