Book Biologie des poissons d eau douce europ  ens  2e   d

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.

Book Limnology  Climatology and Paleoclimatology of the East African Lakes

Download or read book Limnology Climatology and Paleoclimatology of the East African Lakes written by Thomas C Johnson and published by Routledge. This book was released on 2019-08-13 with total page 679 pages. Available in PDF, EPUB and Kindle. Book excerpt: The large lakes of the East African Rift Valley are among the oldest on Earth, and are vital resources for the people of their basins. They are unique among the large lakes of the world in terms of their sensitivity to climatic change, rich and diverse populations of endemic species, circulation dynamics and water-column chemistry, and long, continuous records of past climatic change. A comprehensive study of the large African lakes is long overdue. The scientific justification for such an effort is noted in the previous paragraph and is illustrated in great detail in this volume. Societal need for the sustainable utilization of these lakes offers an even more compelling reason for examination of biological food webs, water quality, and past climate variability in East Africa. The lakes provide the most important source of protein for the people of the African Rift Valley, and fish populations are shifting dramatically in response to fishing pressure, introduction of exotic species, land use impact on water quality, and perhaps climatic change. Current estimates of primary productivity, the underpinning of the food resource, are extremely crude and based on only a few spot measurements.

Book Invasive Alien Species

Download or read book Invasive Alien Species written by Michael R. Ielmini and published by John Wiley & Sons. This book was released on 2021-04-21 with total page 1488 pages. Available in PDF, EPUB and Kindle. Book excerpt: Jedes Jahr breiten sich invasive gebietsfremde Arten in neue Ökosysteme aus. Die von den Eindringlingen verursachten Auswirkungen können sich in kürzester Zeit bemerkbar machen und verheerend sein. Das Thema der invasiven gebietsfremden Arten ist umfassend, komplex und auf verschiedenen Ebenen von globaler Bedeutung. Verschärft wird es durch die Globalisierung der Weltwirtschaft und den zunehmenden Handel, durch den die natürlichen Barrieren für den Transfer von Arten durchbrochen werden. Invasive gebietsfremde Arten bedrohen die weltweite Nahrungsmittelversorgung, die Qualität und Verfügbarkeit von Trinkwasser sowie die Stromproduktion und -versorgung. Zusammen mit den zusätzlichen Risiken durch den globalen Klimawandel ist die weltweite Homogenisierung von Pflanzen, Tieren und Mikroben ein wesentlicher Faktor für den sich verschlechternden Gesundheitszustand der Ökosysteme und die nachlassenden Ökosystemdienstleistungen überall auf der Welt. Um dieser Entwicklung entgegenzuwirken, besteht die dringende Notwendigkeit einer einheitlichen Ausrichtung von Regierungen, Kulturen und Programmen und einer besseren grenzüberschreitenden Koordination. Nur so lassen sich die vielfältigen Bedrohungen durch invasive gebietsfremde Arten für die Umwelt, die Wirtschaft und die Gesundheit von Pflanzen und Tieren sowie insbesondere die menschliche Gesundheit effektiv bekämpfen. Dieses vierbändige Werk ist das erste, das einen umfassenden Satz nützlicher Materialien zu den zentralen Themen bereitstellt, um die gesamte globale Bedrohung durch invasive gebietsfremde Arten sowie die vielfältigen Probleme in verschiedenen Teilen der Welt deutlich zu machen, und es enthält Material, in dem potenziell replizierbare Lösungen zur Überwindung dieser Bedrohungen aufgezeigt werden. Das Werk betont die Bedrohung durch invasive gebietsfremde Arten auch im Sinne eines globalen ?Aufrufs zum Handeln?. Invasive Arten kennen keine Grenzen. Daher hoffen wir, dass wir durch die Zusammenstellung von Material, das unterschiedliche wissenschaftliche und gesellschaftliche Standpunkte aus aller Welt berücksichtigt, sowie durch die Vermittlung von Erkenntnissen und Beispielen zu einer Vielzahl damit zusammenhängender Themen das globale Bewusstsein stärken und einheitliche nationale Reaktionen auf die Bedrohung durch invasive gebietsfremde Arten fördern können.
