The Birds of South America by Robert S. Ridgely,Tudor Guy Pdf

A land of incredible natural resources, the South American continent is rich in plant and animal species. Among birds alone, over 3,100 species are either resident or migrant. Birds are some of South America's treasures and also one of its most endangered resources. Hence the need for a descriptive record of South American birds that will serve both professional and amateur bird students and encourage conservation of these magnificent species. Although South American birds elicit much popular and scientific interest, they have never been completely or satisfactorily described and cataloged in a single, published source. The Birds of South America, projected to be a four-volume work, thus fills a critical void. Starting from a museum approach, the authors have examined specimens of each subspecies, comparing them visually and trying to discern the patterns in their plumage variation, both intra- and inter-specifically. They take a new look at bird systematics, reassessing relationships in light of new information. Perhaps most important, they combine this review and analysis with extensive field observations to give an accurate, incisive portrait of the birds in nature. At a time when rapid development is devastating millions of acres of tropical habitat in South America, this record of an endangered resource becomes crucial. If the birds and other plants and animals of South America are to be saved, they must first be known and appreciated. The Birds of South America is a major step in that direction. Volume I includes the Jays and Swallows; Wrens, Thrushes, and Allies; Vireos and Wood-warblers; Tanagers, Icterids, and Finches. The remaining volumes of The Birds of South America will be: Volume III: The Nonpasserines (Landbirds) Volume IV: The Nonpasserines (Waterbirds) No release date has been set for the remaining volumes.

Conservation Biology for All by Navjot S. Sodhi,Paul R. Ehrlich Pdf

Conservation Biology for All provides cutting-edge but basic conservation science to a global readership. A series of authoritative chapters have been written by the top names in conservation biology with the principal aim of disseminating cutting-edge conservation knowledge as widely as possible. Important topics such as balancing conversion and human needs, climate change, conservation planning, designing and analyzing conservation research, ecosystem services, endangered species management, extinctions, fire, habitat loss, and invasive species are covered. Numerous textboxes describing additional relevant material or case studies are also included. The global biodiversity crisis is now unstoppable; what can be saved in the developing world will require an educated constituency in both the developing and developed world. Habitat loss is particularly acute in developing countries, which is of special concern because it tends to be these locations where the greatest species diversity and richest centres of endemism are to be found. Sadly, developing world conservation scientists have found it difficult to access an authoritative textbook, which is particularly ironic since it is these countries where the potential benefits of knowledge application are greatest. There is now an urgent need to educate the next generation of scientists in developing countries, so that they are in a better position to protect their natural resources.

Correction Lines by Curt Meine Pdf

The last fifteen years have been a period of dramatic change, both in the world at large and within the fields of ecology and conservation. The end of the Cold War, the dot-com boom and bust, the globalizing economy, and the attacks of September 11, among other events and trends, have reshaped our worldview and the political environment in which we find ourselves. At the same time, emerging knowledge, needs, and opportunities have led to a rapid evolution in our understanding of the scientific foundations and social context of conservation. Correction Lines is a new collection of essays from one of our most thoughtful and eloquent writers on conservation, putting these recent changes into perspective and exploring the questions they raise about the past, present, and future of the conservation movement. The essays explore interrelated themes: the relationship between biological and social dimensions; the historic tension between utilitarian and preservationist approaches; the integration of varied cultural perspectives; the enduring legacy of Aldo Leopold; the contrasts and continuities between conservation and environmentalism; the importance of political reform; and the need to "retool" conservation to address twentyfirst-century realities. Collectively the essays assert that we have reached a critical juncture in conservation-a "correction line" of sorts. Correction Lines argues that we need a more coherent and comprehensive account of the past if we are to understand our present circumstances and move forward under unprecedented conditions. Meine brings together a deep sense of history with powerful language and compelling imagery, yielding new insights into the origins and development of contemporary conservation. Correction Lines will help us think more clearly about the forces that have changed, and are changing, conservation, and inspire us to address current realities and future needs.

Mixed-Species Groups of Animals by Eben Goodale,Guy Beauchamp,Graeme D. Ruxton Pdf

Mixed-Species Groups of Animals: Behavior, Community Structure, and Conservation presents a comprehensive discussion on the mixed-species groups of animals, a spectacular and accessible example of the complexity of species interactions. They are found in a wide range of animals, including invertebrates, fish, mammals and birds, and in different habitats, both terrestrial and aquatic, throughout the world. While there are more than 500 articles on this subject scattered in separate categories of journals, there has yet to be a general, cross-taxa book-length introduction to this subject that summarizes the behavior and community structure of these groups. The authors first survey the diversity of spatial associations among animals and then concentrate on moving groups. They review the major classes of theories that have been developed to explain their presence, particularly in how groups increase foraging efficiency and decrease predation. Finally, they explore the intricacies of species interactions, such as communication, that explain species roles in groups and discuss what implications these social systems have for conservation. Functions as a single resource for readers inside and outside of academia on mixed-species groups, serving as a foundation for future research in this field Begins with an empirical summary of mixed-species distribution and reviews how the theories explaining their adaptive benefits are supported by the evidence Includes many aspects of mixed-group behavior (e.g. foraging, communication, collective decision-making, dominance, social roles of species and leadership, relationship to conservation) that were not previously or easily accessible

Reed and Bush Warblers by Peter Kennerley,David Pearson Pdf

This detailed and comprehensive identification guide follows in the mould of Sylvia Warblers and Pipits and Wagtails. It primarily covers the genera Acrocephalus, Locustella, Cettia and Bradypterus, together with a few smaller related genera. To the uninitiated, these are the archetypal 'little brown jobs' and as if they weren't hard enough to identify anyway, many of them are hard to see as well! This authoritative handbook covers their identification in breathtaking detail, illustrated with line drawings, sonograms, wonderful colour plates and photographs. It is destined to become the ultimate reference for these challenging birds.

On the Move by Sue Boinski,Paul A. Garber Pdf

Examines social, cognitive, and ecological processes that underlie patterns and strategies of group travel. Chapters discuss how factors such as group size, resource distribution, and costs of travel affect individual and group exploitation of the environment. Most chapters focus on field studies of human and nonhuman primate groups, from squirrel monkeys to Turkana pastoralists. Chapters on other species provide a broad taxonomic perspective.
