für 29.32€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Our species has transitioned from being one among millions on Earth to the species that is single-handedly transforming the entire planet to suit its own needs. In order to meet the daunting challenges of environmental sustainability, ecologists have begun to think differently about the interdependencies between humans and the natural world. Oswald Schmitz describes how the science of ecology is evolving to provide a better understanding of how human agency is shaping the natural world, often in never-before-seen ways. The new ecology emphasizes the importance of conserving species diversity, because it can offer a portfolio of options to keep our ecosystems resilient in the face of environmental change. It envisions humans taking on new roles as thoughtful stewards of the environment to ensure that ecosystems have the enduring capacity to supply the environmental services on which our economic well-being - and our very existence - depend. It offers the ecological know-how to maintain and enhance our planets environmental performance and ecosystem production for the benefit of current and future generations. ····· 1017675545
für 30.52€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Les poissons Téléostéens constituent un potentiel halieutique important le long des côtes algériennes L`exploitation durable de ce potentiel nécessite de comprendre la nature et la qualité des habitats de ponte. Une des nouvelles méthodes utilisées en halieutique dans l`évaluation des stocks est le suivi spatio-temporel de l`ichtyoplancton. Elle est utilisée pour estimer la taille d`un stock reproducteur à partir des ufs produits. En Algérie à l`exception des travaux de MARINARO 1970 peu de travaux ont porté sur l`étude de l`ichtyoplancton Il semble alors très important d`actualiser les connaissances sur la ponte et le fonctionnement des zones de frayères. Malgré la diversité spécifique de ces poissons, nous avons pu déterminer les ufs de 14 espèces appartenant à 11 familles Ces ufs présentent les mêmes caractéristiques décrites dans la littérature, les différences résident dans leur répartition spatio-temporelle. Enfin, il paraît nécessaire de mettre en uvre des travaux plus détaillés pour avoir des informations sur la répartition et les variations spatio-temporelles de l`ichtyoplancton, qui est une composante très utilisée dans les nouvelles méthodes d`évaluation des stocks. ····· 1017631299
für 40.93€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Grain production is a complex phenomenon, entailing several contributing factors. These factors influence grain production both directly and indirectly and the breeder is naturally interested in investigating the extent and type of association of such traits. Towards a clear understanding of the type of association, correlation, path and divergence analysis are logical steps. Studies like heritability estimates could also be helpful to know the performance of parents in hybrids. Similarly, Knowledge on the extent and the pattern of genetic variability present in a population is essential for further improvement of any crop. At present, there is lack of detailed information pertaining to these aspects. Therefore, this book intends to show comprehensive logical steps that a plant scientist should follow to reach a concrete conclusion on the variability and genetic relation of different characters taking an experiment conducted in bread wheat as an example. The book is important for plant breeders and other plant scientists interested in learning more about the ways of crop improvement. ····· 1017626200
für 52.95€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Im Rahmen dieser Arbeit wird eine neue Methodik zur flächendeckenden Ermittlung belastbarer Daten für anthropogene Emissionen entwickelt. Dabei wird explizit die Verfügbarkeit von Ausgangsdaten, bedingt durch Datenschutz, Nichterhebung etc., berücksichtigt. Die aufgezeigten Möglichkeiten zur Generierung von Emissionsdaten bilden eine wesentliche Grundlage für die Erstellung von nationalen und internationalen Emissionskatastern. Sie dienen somit als Basis für die Umsetzung von Emissionsminderungsstrategien sowie als nichtmonetäre Datenbasis einer Umweltberichterstattung, etwa innerhalb einer Umweltökonomischen Gesamtrechnung. Als ein besonders emissionsrelevanter Beispielsektor wurde die Energieerzeugung ausgewählt. ····· 101767027
