Download or read book Biologie des poissons d eau douce europ ens 2e d written by BRUSLÉ Jacques and published by Lavoisier. This book was released on 2013-07-01 with total page 802 pages. 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.

This book was released on 2007 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: Un objectif récurrent en écologie concerne la connaissance des traits d’histoire de vie et de leur variabilité. En eau douce, les contraintes environnementales sont omniprésentes pour les poissons et jouent un rôle important dans la variabilité des traits d’histoire de vie des organismes. Dans ce cadre, l’objectif principal de cette thèse consiste à étudier les liens entre les traits des poissons d’eau douce européens et l’environnement en privilégient une approche à plusieurs niveaux biologiques (population et espèce) et échelles spatiales (continentale, régionale et locale). Grâce à une importante somme de données biologiques et environnementales acquises à la fois par une vaste recherche bibliographique à l’échelle de l’Europe et un important travail de terrain sur le bassin Rhodanien, ce travail illustre (1) un effet de la température à l’échelle continentale et régionale sur plusieurs traits de populations, qui ne se confirme cependant pas pour toutes les espèces et (2) un effet très faible de l’hydraulique à l’échelle continentale et régionale sur les traits des populations. A l’opposé, au niveau de l’espèce, les relations entre les traits et l’hydraulique semblent prédominer sur les relations entre les traits et la température. L’hydraulique à l’échelle du micro-habitat joue un rôle d’ "habitat template" pour les stratégies des espèces, les milieux peu profonds et rapides sélectionnant les espèces à stratégie démographique opportuniste. La comparaison entre la variabilité intraspécifique et la variabilité interspécifique des traits illustre la pertinence d’utiliser dans les approches comparatives interspécifiques et inter-communautés des traits d’espèces mesurés à l’échelle régionale et des traits d’espèces issus de la littérature comme la fécondité et les traits liés à la taille, et cela malgré leur variabilité intraspécifique. En intégrant la variabilité de nombreux traits à plusieurs niveaux biologiques et échelles spatiales, ma thèse apporte des éléments de réflexion aux écologues de différentes disciplines telles que la dynamique et la biologie des populations, la biologie des espèces, l’écologie des communautés et l’écologie évolutive

Available in PDF, EPUB and Kindle. Book excerpt: Sex is the queen of problems in evolutionary biology. Generations of researchers have investigated one of the last remaining evolutionary paradoxes: why sex exists at all. Given that sexual reproduction is costly from an evolutionary point of view, one could wonder why not all animals and plants reproduce asexually. Dozens of contemporary hypotheses attempt to explain the prevalence of sex and its advantages and predict the early extinction of fully asexual lineages. The major theme of this book is: what is the fate of animal and plant groups in which sex is lost? Initial chapters discuss theory behind asexual life: what major disadvantages do asexual groups have to face, what are the genetic and ecological consequences and what does this theory predict for more applied aspects of asexual life, for example in agricultural pests, diseases as well as in cultural crops such as grapes. Cases studies in many animals (focusing on both invertebrates and vertebrates) and plants reveal parallel, but also singularly novel adaptations to the absence of meiosis and syngamy. And last but not least, are asexuals really doomed to early extinction or do genuine ancient asexuals exist? This book assembles contributions from the most important research groups dealing with asexual evolution in eukaryotes. It is a milestone in research on parthenogenesis and will be useful to undergraduate as well as graduate students and to senior researchers in all fields of evolutionary biology, as the paradox of sex remains its queen of problems.
Download or read book Traditional Forest Related Knowledge written by John A. Parrotta and published by Springer Science & Business Media. This book was released on 2011-10-14 with total page 639 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exploring a topic of vital and ongoing importance, Traditional Forest Knowledge examines the history, current status and trends in the development and application of traditional forest knowledge by local and indigenous communities worldwide. It considers the interplay between traditional beliefs and practices and formal forest science and interrogates the often uneasy relationship between these different knowledge systems. The contents also highlight efforts to conserve and promote traditional forest management practices that balance the environmental, economic and social objectives of forest management. It places these efforts in the context of recent trends towards the devolution of forest management authority in many parts of the world. The book includes regional chapters covering North America, South America, Africa, Europe, Asia and the Australia-Pacific region. As well as relating the general factors mentioned above to these specific areas, these chapters cover issues of special regional significance, such as the importance of traditional knowledge and practices for food security, economic development and cultural identity. Other chapters examine topics ranging from key policy issues to the significant programs of regional and international organisations, and from research ethics and best practices for scientific study of traditional knowledge to the adaptation of traditional forest knowledge to climate change and globalisation.
