Download or read book Reproduction and Sexuality in Marine Fishes written by Kathleen S. Cole and published by Univ of California Press. This book was released on 2010-10-28 with total page 643 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine fishes represent astonishing diversity with respect to practically every aspect of their biology. Reproductive modes and sexual patterns are especially fascinating and provide deep insight into general evolutionary problems. In this volume, chapters focus on reproduction and sexuality among groups of fishes defined by habitat, taxon, and the reproductive processes that are critical for reproductive success. The book illustrates how knowledge of reproductive biology among marine fishes can help identify vulnerable and potentially vulnerable species in the face of changing environmental conditions and increasing human-based pressures.

Book excerpt: The unprecedented level of diversity recorded among the clones of self-fertilizing gynogenetic unisexuals and self-fertilizing simultaneous hermaphrodites challenges current ideas on the predominant role of recombination in promoting evolution of biological diversity. Though limited to a few species, the existence of self-fertilizing and cycli
Download or read book Reproductive Biology of Teleost Fishes written by Robert J. Wootton and published by John Wiley & Sons. This book was released on 2014-12-03 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reproductive Biology of Teleost Fishes is the first integrated review of the reproductive biology of the bony fishes, which are the most species-rich and diversified group of vertebrates. Teleosts display remarkable variation in their modes of reproduction, and this volume is intended to provide a framework for understanding the remarkable reproductive diversity of this group. It describes their reproductive biology using, wherever possible, phylogenetic analyses and life-history theory as a means to interpret the information. The book addresses the genetic, physiological, behavioural, ecological, evolutionary and applied aspects of teleost reproduction in a comparative framework that emphasises the adaptive basis of reproductive diversity. Reproductive Biology of Teleost Fishes provides a comprehensive synthesis of fish reproduction that will be of great interest to life scientists, particularly ecologists, evolutionary biologists, physiologists and advanced undergraduates, postgraduates and research workers requiring a comprehensive overview of fish reproduction. The book is suitable for courses in fish biology and ecology, reproductive physiology and reproductive genetics. It also addresses applied questions and will be of value for courses on fisheries science and aquaculture. Libraries in all universities and research establishments where biological sciences, fisheries science and aquaculture are studied and taught should have several copies of this important book on their shelves.

This book was released on 1998 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: CETTE THESE S'APPUIE SUR UN ENSEMBLE DE TRAVAUX PERSONNELS, PUBLIES DE 1975 A 1992, SUR LA MODIFICATION EXPERIMENTALE DES MODALITES DE LA REPRODUCTION CHEZ LES POISSONS SALMONIDES. LE PREMIER CHAPITRE EST INTRODUIT PAR L'EXAMEN DE L'EVOLUTION DES IDEES SUR LE DETERMINISME DU SEXE CHEZ LES POISSONS DEPUIS LE DEBUT DU SIECLE. LES TRAVAUX EXPERIMENTAUX PERSONNELS REALISES CHEZ LA TRUITE ARC-EN-CIEL (ONCORHYNCHUS MYKISS) ET LA TRUITE COMMUNE (SALMO TRUTTA) SONT ENSUITE EXPOSES. ILS ONT PORTE D'UNE PART SUR L'INVERSION HORMONALE PARTIELLE (PRODUCTION D'HERMAPHRODITES) OU TOTALE DU PHENOTYPE SEXUEL, D'AUTRE PART SUR L'INDUCTION DE LA GYNOGENESE DIPLOIDE. L'ETUDE DES SEX-RATIOS DES GROUPES D'ANIMAUX RESULTANT DE CES TRAITEMENTS A PERMIS DE CONCLURE NETTEMENT A L'EXISTENCE D'UN MODELE DE DETERMINISME GENETIQUE DU SEXE DU TYPE MALE HETEROGAMETIQUE CHEZ CES ESPECES. LA FIN DU CHAPITRE SITUE CE MODELE PAR RAPPORT AUX DONNEES BIBLIOGRAPHIQUES RECENTES ET PROPOSE UNE LECTURE EVOLUTIVE DE LA DIVERSITE DES PHENOTYPES SEXUELS DES POISSONS. LE SECOND CHAPITRE DEBUTE PAR UNE REVUE DES OBSERVATIONS D'HYBRIDES ET DE POLYPLOIDES NATURELS, EN EXAMINANT PLUS PARTICULIEREMENT LE CAS OU CES GENOTYPES SONT OBSERVES A UNE FREQUENCE RELATIVEMENT ELEVEE. IL SE POURSUIT PAR UNE PRESENTATION DES RESULTATS PERSONNELS OBTENUS SUR L'INDUCTION DE LA TRIPLOIDIE ET DE LA TETRAPLOIDIE ET SUR LA CARACTERISATION DES ANIMAUX OBTENUS, EN TERMES DE VIABILITE, CROISSANCE ET FERTILITE. LES NOMBREUSES EXPERIENCES REALISEES POUR PRECISER LES POSSIBILITES D'HYBRIDATION INTERSPECIFIQUE CHEZ LES SALMONIDES SONT ENSUITE RELATEES. HYBRIDATION ET INDUCTION DE LA TRIPLOIDIE SONT ENFIN COMBINEES POUR OBTENIR ET CARACTERISER DES HYBRIDES TRIPLOIDES VIABLES ENTRE LA TRUITE ARC-EN-CIEL FEMELLE ET PLUSIEURS AUTRES SALMONIDES UTILISES COMME MALES. L'INTERET DE CES METHODES POUR OBTENIR DES ANIMAUX STERILES RESISTANT AUX VIROSES EST PARTICULIEREMENT SOULIGNE. LE CHAPITRE EXAMINE POUR FINIR L'IMPORTANCE DE LA DEPRESSION DE TRIPLOIDIE RELATEE DANS LA LITTERATURE SUR DIVERSES ESPECES ET LES MECANISMES RESPONSABLES DE CETTE DEPRESSION. LES FACTEURS CONDUISANT A LA VIABILITE ET A LA STERILITE DES HYBRIDES SONT EGALEMENT DISCUTES.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Biologie des poissons d’eau douce européens, par son champ d’étude vaste et ambitieux, est un ouvrage de référence en ichtyologie dulçaquicole. Couvrant l’ensemble des aspects écologiques, écobiologiques, écophysiologiques et éthologiques, il dresse une présentation détaillée de 88 espèces auto- ou allochtones : morphologie, anatomie, distribution géographique, habitats, modes de vie et activités physiologiques. 453 autres espèces sont également répertoriées. Cette 2e édition a été largement revue et augmentée, compte tenu de l’importance des données scientifiques récentes. Outre des compléments utiles portant sur les habitats et les modes de vie, cet ouvrage s’enrichit des nombreux apports génétiques qui ont parfois « révolutionné » les concepts anciens relatifs aux origines paléo-historiques et paléo-géographiques des espèces. Des extensions ou des réductions de répartitions géographiques ont été consécutives à des transferts d’origine anthropique, à des dégradations physiques et chimiques et à la récente influence du Global Warming, sans oublier les changements de statut dans le domaine de la systématique. Au fil d’un livre d’une grande rigueur scientifique, abondamment illustré (dont 64 aquarelles originales et plus de 70 cartes géographiques pertinentes) et complété par un glossaire et une importante bibliographie, le lecteur abordera la connaissance des poissons européens d’une façon à la fois originale et attrayante. Cet ouvrage s’adresse à un large public : étudiants de 2e et 3e cycles en biologie, zoologie, écologie, hydrobiologie, environnement, ingénieurs et techniciens chargés de l’aménagement, de la gestion, de la qualité et de la protection des milieux aquatiques (services vétérinaires, de l’Environnement, de l’Agriculture, de l’Équipement…) auxquels il apportera les bases fondamentales nécessaires à leur action, et plus largement tous les passionnés d’ichtyofaune.

Download or read book Reproductive Biology of Invertebrates Accessory Sex Glands written by and published by John Wiley & Sons. This book was released on 1993-03-02 with total page 550 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reproductive Biology of Invertebrates Volume III Accessory Sex Glands Edited by K. G. Adiyodi Accessory Sex Glands is the third volume in the encyclopaedic series and provides very valuable information, some hitherto unpublished, on the distribution, structure, origin physiology, biochemistry, pharmacology and evolution of the accessory sex glands in different groups of invertebrates. Volumes I and II of this series (published by Wiley) have given detailed accounts of the structure, origin, composition and physiology of female and male gametes and also provided some information on the mechanisms controlling their production. The secretions of accessory sex glands are indispensable for several key aspects of gamete physiology and for successful fertilization and development in many internally fertilizing invertebrates. Interestingly enough, accessory sex gland secretions are produced, in some species at least, under the influence of gonadotrophic hormones as are the gametes themselves. The data on invertebrate accessory sex glands are scattered in various journals and have not been so far collected, critically evaluated and published in book form. This volume thus fills a void and serves as an indispensable corollary and companion to the two volumes that have already appeared on gametology in the series.
