Book excerpt: Excerpt from The Food Habits and Nesting Success of Wood Storks in Everglades National Park in 1974 Food of Wood Storks was determined by obtaining regurgitation samples from nest lings in colonies and from adults at feeding sites. Nestling storks regurgitate readily when handled. We found that when we used a helicopter to fly close to feeding adult storks, they would regurgitate food onto the ground before flying away. We then landed to collect the regurgitation and took several drop - trap or throw - trap samples of fish at the same place where regurgitation samples were obtained (fig. Thus we were able to compare the species and sizes of fish available to those taken by storks. The data collected at feeding sites were combined for analysis into three habitats coastal, mangrove headwaters, and Ever glades. Fishes collected during the study were preserved and later identified, counted, and measured for total length and dry weight. Aerial surveys, conducted two to four times per month, were used to locate feeding storks, follow storks from colony sites to feeding grounds, observe nesting colonies, census nests, and monitor stage of nesting. More detailed observations on the development of young, number of young in nests, survival of nestlings, and daily activity of adults were obtained by ground visits to the rookeries.

Download or read book Conservation by Proxy written by Tim Caro and published by Island Press. This book was released on 2010-06-23 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vast scope of conservation problems has forced biologists and managers to rely on "surrogate" species to serve as shortcuts to guide their decision making. These species-known by a host of different terms, including indicator, umbrella, and flagship species-act as proxies to represent larger conservation issues, such as the location of biodiversity hotspots or general ecosystem health. Synthesizing an immense body of literature, conservation biologist and field researcher Tim Caro offers systematic definitions of surrogate species concepts, explores biological theories that underlie them, considers how surrogate species are chosen, critically examines evidence for and against their utility, and makes recommendations for their continued use. The book clarifies terminology and contrasts how different terms are used in the real world considers the ecological, taxonomic, and political underpinnings of these shortcuts identifies criteria that make for good surrogate species outlines the circumstances where the application of the surrogate species concept shows promise Conservation by Proxy is a benchmark reference that provides clear definitions and common understanding of the evidence and theory behind surrogate species. It is the first book to review and bring together literature on more than fifteen types of surrogate species, enabling us to assess their role in conservation and offering guidelines on how they can be used most effectively.
Download or read book The Green Republic written by Sterling Evans and published by University of Texas Press. This book was released on 2010-06-28 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: With over 25 percent of its land set aside in national parks and other protected areas, Costa Rica is renowned worldwide as "the green republic." In this very readable history of conservation in Costa Rica, Sterling Evans explores the establishment of the country's national park system as a response to the rapid destruction of its tropical ecosystems due to the expansion of export-related agriculture. Drawing on interviews with key players in the conservation movement, as well as archival research, Evans traces the emergence of a conservation ethic among Costa Ricans and the tangible forms it has taken. In Part I, he describes the development of the national park system and "the grand contradiction" that conservation occurred simultaneously with massive deforestation in unprotected areas. In Part II, he examines other aspects of Costa Rica's conservation experience, including the important roles played by environmental education and nongovernmental organizations, campesino and indigenous movements, ecotourism, and the work of the National Biodiversity Institute.

This book was released on 2013-06-29 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: National parks and protected areas offer a wealth of ecological and social contributions or services to humans and life on earth. This book describes the strengths of national parks and protected areas in different parts of Europe and North America and the challenges to the full realization of their goals. It shows that they are useful not only in conserving rare species and biodiversity, but also in protecting water supply and other resources necessary to tourism and to economic and social development generally. Ideas and information on useful planning, management and decision-making arrangements are presented, and research needs are identified.
Download or read book Microbial Zoonoses and Sapronoses written by Zdenek Hubálek and published by Springer Science & Business Media. This book was released on 2010-11-25 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the state of art in the field of microbial zoonoses and sapronoses. It could be used as a textbook or manual in microbiology and medical zoology for students of human and veterinary medicine, including Ph.D. students, and for biomedicine scientists and medical practitioners and specialists as well. Surprisingly, severe zoonoses and sapronoses still appear that are either entirely new (e.g., SARS), newly recognized (Lyme borreliosis), resurging (West Nile fever in Europe), increasing in incidence (campylobacterosis), spatially expanding (West Nile fever in the Americas), with a changing range of hosts and/or vectors, with changing clinical manifestations or acquiring antibiotic resistance. The collective term for those diseases is (re)emerging infections, and most of them represent zoonoses and sapronoses (the rest are anthroponoses). The number of known zoonotic and sapronotic pathogens of humans is continually growing − over 800 today. In the introductory part, short characteristics are given of infectious and epidemic process, including the role of environmental factors, possibilities of their epidemiological surveillance, and control. Much emphasis is laid on ecological aspects of these diseases (haematophagous vectors and their life history; vertebrate hosts of zoonoses; habitats of the agents and their geographic distribution; natural focality of diseases). Particular zoonoses and sapronoses are then characterized in the following brief paragraphs: source of human infection; animal disease; transmission mode; human disease; epidemiology; diagnostics; therapy; geographic distribution.

Available in PDF, EPUB and Kindle. Book excerpt: Many books have now been published in the broad field of environmental toxicology. However, to date, none of have presented the often fascinating stories of the wildlife science, and the steps along the way from discovery of problems caused by environmental pollutants to the regulatory and non-regulatory efforts to address the problems. This book provides case by case examinations of how toxic chemical effects on wildlife have brought about policy and regulatory decisions, and positive changes in environmental conditions. Wild animal stories, whether they are about the disappearance of charismatic top predators, or of grossly deformed embryos or frogs, provide powerful symbols that can and have captured the public's imagination and have resulted in increased awareness by decision makers. It is the intent of this book to present factual and balanced overviews and summaries of the science and the subsequent regulatory processes that followed to effect change (or not). We cover a variety of chemicals and topics beginning with an update of the classic California coastal DDT story of eggshell thinning and avian reproduction to more recent cases, such as the veterinarian pharmaceutical that has brought three species of Asian vultures to the brink of extinction. Researchers, regulators, educators, NGOs and the general public will find valuable insights into the processes and mechanisms involved both in environmental scientific investigation and in efforts to effect positive change.
Download or read book Carrion Ecology and Management written by Pedro P. Olea and published by Springer. This book was released on 2019-07-22 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carrion, or dead animal matter, is an inherent component of aquatic and terrestrial ecosystems worldwide, and is exploited by a wide diversity of organisms from different trophic levels, including microbes, arthropods and vertebrates. Further, carrion consumption by scavengers, i.e. scavenging, supports key ecosystem functions and services such as recycling nutrients and energy, disposing of carcasses and regulating disease spread. Yet, unlike dead plant matter, dead animal decomposition has received little attention in the fields of ecology, wildlife conservation and environmental management, and as a result the management of carrion for maintaining biodiversity and functional ecosystems has been limited. This book addresses the main ecological patterns and processes relating to the generation and consumption of carrion both in terrestrial and aquatic ecosystems. It also discusses a number of conservation concerns and associated management issues, particularly regarding the increasing role of human-mediated carrion in ecosystems. Lastly, the book outlines future research lines in carrion ecology and management, and identifies the major challenges for scavengers and scavenging processes in the Anthropocene.
