Download or read book Feeding Ecology of and Lead Exposure in a Top Predator written by Mirjam Nadjafzadeh and published by Logos Verlag Berlin GmbH. This book was released on 2011 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the feeding ecology of raptors has attracted the attention of many scientists, aspects such as diet selection and foraging strategy are still poorly understood. This is particularly true for large species such as the white-tailed eagle. Representative assessments of the contribution of food sources containing toxins such as lead to raptor diets are scarce but are essential for optimising conservation efforts. This dissertation investigated the feeding ecology of white-tailed eagles to shed light on the interaction of such top predators with their environment and to improve the conservation management of this lead-exposed species. A use of complementary methods identified the most effective approach for dietary investigations on free-ranging raptors. The findings revealed that the foraging strategy of white-tailed eagles is influenced by both individual and environmental factors and corresponds to an efficient food intake in terms of optimal foraging theory. The main sources of lead fragments that induce fatal lead poisoning are shot mammalian carcasses which constitute important alternative diet components for white-tailed eagles during the hunting season. One approach to solve the lead poisoning problem can be the use of lead-free bullets by hunters that fragment into sufficiently large particles which would be avoided by scavenging eagles and birds with similar feeding behaviour.
Download or read book The Great Eagles written by Michael O'Neal Campbell and published by CRC Press. This book was released on 2022-05-19 with total page 648 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines the current literature and knowledge on the evolution and ecology of all the birds named as eagles, with particular emphasis on the larger species. It also examines the past and current relations between eagles and people, including habitat change and conservation issues. Eagle ecologies and conservation are currently seriously impacted by human activities such as industrialization, urbanization, pollution, deforestation and hunting. Some eagle species have consequently experienced extreme population changes. There are, however, some positive developments. Eagles have a strong, historic bond with human civilization, due to their status as the world’s most charismatic birds. Conservation policies have also been successful in repopulating some ecosystems with breeding eagles. Therefore, despite the complexity of this relationship, there may yet be hope for this unique species group, frequently rated as the kings of birds, and symbolic of human power, ambition, royalty, nationality, and even concepts of God. It is hoped that this book will contribute to the further understanding of these unique and fantastic birds.

Download or read book Environmental Chemistry written by Dr. Rajendra S. Gaikwad and published by Ashok Yakkaldevi. This book was released on 2022-12-31 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every year, pollution in the environment rises, causing serious and irreparable harm to the world. There are many different kinds of pollution, including air, water, soil, noise, and light-weight pollution. The living system is harmed as a result of these. There has been a significant shift in how pollution affects public health, environmental medicine, and the environment. Environmental pollution was neither a medical or public health issue nor was it discussed in clinical settings until recent oil spills in the Yellowstone River, Alaska's tundra, and Enbridge (Wisconsin) demonstrate how pollution can affect man's health directly or indirectly. Environmental medicine has become more widely discussed since the 1950s as a result of increased awareness in public health and preventive medicine; despite the fact that occupational medicine is now the primary focus. However, environmental and occupational medicine are typically thought of as a combined field with an emphasis on industrial issues. As a result of the pollutant's low complexity, degradability (such as biodegradable organics), and lack of industrialization, pollution issues were, without a doubt, recognized in the distant past.

Download or read book Community Ecology written by Gary George Mittelbach and published by . This book was released on 2019 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Community ecology has undergone a transformation in recent years, from a discipline largely focused on processes occurring within a local area to a discipline encompassing a much richer domain of study, including the linkages between communities separated in space (metacommunity dynamics), niche and neutral theory, the interplay between ecology and evolution (eco-evolutionary dynamics), and the influence of historical and regional processes in shaping patterns of biodiversity. To fully understand these new developments, however, students continue to need a strong foundation in the study of species interactions and how these interactions are assembled into food webs and other ecological networks. This new edition fulfils the book's original aims, both as a much-needed up-to-date and accessible introduction to modern community ecology, and in identifying the important questions that are yet to be answered. This research-driven textbook introduces state-of-the-art community ecology to a new generation of students, adopting reasoned and balanced perspectives on as-yet-unresolved issues. Community Ecology is suitable for advanced undergraduates, graduate students, and researchers seeking a broad, up-to-date coverage of ecological concepts at the community level.
Download or read book Rotifers written by Atsushi Hagiwara and published by Springer. This book was released on 2017-09-22 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights the latest advances in rotifer studies in various fields including aquaculture, ecology, gerontology and ecotoxicology. The genus Brachionus are an indispensable type of zooplankton, having served as an initial live food for marine larval rearing since the 1960s. Their mass culture techniques have been intensively studied, and some essential achievements have been made – regarding high density culture, employment of valuable dietary algae, automated culture systems, and effective production of resting eggs. These have in turn supported stable and efficient aquatic seedling production for numerous important marine fish species including flounder, sea bream, and bluefin tuna. Further, this group is considered to be a suitable model for studying various aspects in ecology. A series of aquaculture and basic science studies have significantly advanced our understanding of the life history evolution. The studies in these two fields are closely linked, and provide readers with comprehensive information on how rotifers are now being employed in biological investigations.

Download or read book Lead Toxicity Mitigation Sustainable Nexus Approaches written by Nitish Kumar and published by Springer Nature. This book was released on 2024-01-13 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited book brings together a diverse group of researchers to address the challenges posed by global mass poisoning caused by lead contamination of soil and plants. Lead is among the elements that have been most extensively used by man over time. This has led to extensive pollution of surface soils on the local scale, mainly associated with mining and smelting of the metal and addition of organic lead compounds to petrol. Release of lead to the atmosphere from various high-temperature processes has led to surface contamination on the regional and even global scale. Lead is particularly strongly bound to humic matter in organic-rich soil and to iron oxides in mineral soil and is rather immobile in the soil unless present at very high concentrations. In addition, plants grown on lead-rich soils incorporate lead and thus the concentration of lead in crop plants may be increased. Lead enters in the food chain through consumption of plant material. A high concentration of lead has been found to be harmful to vegetation. As the lead concentration increases, it adversely affects several biological parameters and eventually renders the soil barren. The book sheds light on this global environmental issue and proposes solutions to contamination through multi-disciplinary approaches. This book contains three sections. First section describes the different sources and distribution of lead in soil and plant ecosystems. Second section explains the health risks linked to lead toxicity. Third section addresses sustainable lead toxicity mitigation strategies using the potential applications of recent biological technology. This book is a valuable resource to students, academics, researchers, and environmental professionals doing field work on contamination throughout the world.

Download or read book A History of Technology and Environment written by Edward L. Golding and published by Taylor & Francis. This book was released on 2016-12-08 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an accessible overview of the ways that key areas of technology have impacted global ecosystems and natural communities. It offers a new way of thinking about the overall origins of environmental problems. Combining approaches drawn from environmental biology and the history of science and technology, it describes the motivations behind many technical advances and the settings in which they occurred, before tracing their ultimate environmental impacts. Four broad areas of human activity are described: over-harvesting of natural resources using the examples of hunting, fishing and freshwater use; farming, population, land use, and migration; discovery, synthesis and use of manufactured chemicals; and development of sources of artificial energy and the widespread pollution caused by power generation and energy use. These innovations have been driven by various forces, but in most cases new technologies have emerged out of fascinating, psychologically rich, human experiences. This book provides an introduction to these complex developments and will be essential reading for students of science, technology and society, environmental history, and the history of science and technology.

Download or read book The Chimpanzees of the Ta Forest written by Christophe Boesch and published by . This book was released on 2000 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: The chimpanzees are the closest living evolutionary relatives to our own species, Homo sapiens. As such, they have long exerted a fascination over those with an interest in human evolution, and what makes humans unique. Chrisophe Boesch and Hedwige Boesch-Acherman undertook an incredible observational study of a group of wild chimpanzees of the Tai forest in Cote D'Ivoire, spending some fifteen years in the West African jungle with them. This fascinating book is the result of these years of painstaking research among the chimps. Chimpanzee behavior is documented here in all its impressive diversity and variety. Aggression, territoriality, social structure and relationships, reproductive strategies, hunting, tool use - each of these is given its own chapter, along with topics such as chimp intelligence, life histories, and demography. The authors take care to place their observations within the broader context of research in behavioral ecology, and to compare and contrast their findings with other important work on chimpanzee groups, such as that by Jane Goodall. The book concludes with a summary chapter relating the chimpanzee findings to our understanding of human evolution. Combining careful scientific observation with a store of entertaining anecdotes, this is a lively and readable book. It also succeeds in shedding light on some of the central questions around the evolutionary relationships between the primates, and in particular the affinity between chimpanzees and humans. 'This is a major contribution to the study of the great apes, and a significant addition to debates about human/ape evolution. It has all the makings of a classic monograph.
