Condition: Hervorragend. Zustand: Hervorragend | Sprache: Deutsch | Produktart: Bücher | Die Ernährung von Fischen ist für die Regulierungsprozesse aquatischer Ökosysteme von größter Bedeutung, da sie nicht so sehr die Verfügbarkeit der im Lebensraum verteilten Nahrung, sondern vielmehr die von den Individuen getroffenen Entscheidungen widerspiegelt. Diese Studie wurde in zwei Bächen im Einzugsgebiet des Peixe - Boi / PA durchgeführt, die sich in unterschiedlichen Stadien der Anthropisierung befinden, mit dem Ziel, die Ernährung der Ichthyofauna zu vergleichen sowie die untersuchten Arten nach ihren Ernährungsgewohnheiten in Fleischfresser, Pflanzenfresser und Allesfresser zu klassifizieren, die Herkunft der Gegenstände, von denen sich diese Tiere ernähren, zu identifizieren, ob sie allochthon oder autochthon sind, und zu charakterisieren, wie diese Beobachtungen in Bezug auf die in den Bächen vorhandenen Fischarten gemacht werden können. Die absolute Bedeutung der Nahrungsbestandteile lässt sich aus dem Grad der Integrität der Gewässer ableiten. Bei insgesamt 58 Individuen wurde der Mageninhalt analysiert, wobei jedes Element gewogen und bis zum kleinstmöglichen Taxon identifiziert wurde, was die Berechnung der Häufigkeit des Vorkommens (Fi), des Index der volumetrischen Analyse (Vi) und des Index der absoluten Bedeutung (AIi) ermöglichte.…

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Studies of herbivory provide important insights into fundamental questions in many areas of the biological sciences. The focus on natural systems is more effective for the prediction of potential changes in ecosystems, given that agricultural systems are designed to create an equilibrium that optimizes the productive process. Given the ramifications of the processes related to herbivory, studies based on complementary approaches are necessary for a better understanding of the different aspects of the ecological process. This book attempts to expand on these different aspects of herbivory by presenting a multidisciplinary approach to a number of different themes, focusing on topics that range from basic research in natural habitats to the intrinsic relationships between animals and plants in agricultural systems. 88 pp. Englisch.…
