Book excerpt: "We estimated that 264 000-452 000 Lesser Snow Geese Chen caerulescens caerulescens nested at Egg Riveron Banks Island, Northwest Territories, in 1995-1998. This was about twice as many geese as was reported nesting there in the 1980s, and we estimated that the nesting population grew by 4.2% per year from 1953 to 1998"--Abstract.

This book was released on 2006-01-01 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Une série de relevés d'oies, de bernaches et de cygnes a été menée dans la région entre 1989 et 2001 dans le but d'établir des estimations appropriées des populations actuelles qui serviront de point de comparaison dans l'avenir et permettront de gérer des récoltes viables à long terme. Les relevés enrichissent considérablement nos connaissances sur la répartition, l'abondance et la productivité des oies, des bernaches et des cygnes dans l'ouest de l'Arctique canadien. Les résultats sont interprétés à la lumière de ce que nous savons sur la situation de ces populations, de même que sur les prises d'oiseaux et sur la diversité des pressions environnementales auxquelles ces populations sont soumises, tant dans la région désignée des Inuvialuits qu'ailleurs en Amérique du Nord.

Download or read book Coviability of Social and Ecological Systems Reconnecting Mankind to the Biosphere in an Era of Global Change written by Olivier Barrière and published by Springer. This book was released on 2019-03-12 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: This second volume is the work of more than 55 authors from 15 different disciplines and includes complex systems science which studies the viability of components, and also the study of empirical situations. As readers will discover, the coviability of social and ecological systems is based on the contradiction between humanity, which adopts finalized objectives, and the biosphere, which refers to a ecological functions. We see how concrete situations shed light on the coviability’s determinants, and in this book the very nature of the coviability, presented as a concept-paradigm, is defined in a transversal and ontological ways. By adopting a systemic approach, without advocating any economic dogma (such as development) or dichotomizing between humans and nature, while emphasizing what is relevant to humans and what is not, this work neutrally contextualizes man’s place in the biosphere. It offers a new mode of thinking and positioning of the ecological imperative, and will appeal to all those working with social and ecological systems.

Available in PDF, EPUB and Kindle. Book excerpt: "This revised edition is not an expanded version of the original, summarizing, for example, the dozens of studies that hve been made of the productivity of various subpopulations of the "Giant Canada Goose" since its rediscovery. Rather, the main objectives of this revised, slightly enlarged edition are to redefine the range of this race as it was originally understood and to correct earlier assumptions based on the literature as to racial identity of peripheral populations."--Page xvii.
