Book Synopsis Feeding Ecology of and Lead Exposure in a Top Predator by : Mirjam Nadjafzadeh
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.
Book Synopsis The Great Eagles by : Michael O'Neal Campbell
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.

Book Synopsis Environmental Chemistry by : Dr. Rajendra S. Gaikwad
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.

Book Synopsis Community Ecology by : Gary George Mittelbach
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.

Book Synopsis Lead Toxicity Mitigation: Sustainable Nexus Approaches by : Nitish Kumar
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.

Book Synopsis A History of Technology and Environment by : Edward L. Golding
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 Atlantic Cod written by George A. Rose and published by John Wiley & Sons. This book was released on 2019-02-26 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive handbook, covering all aspects of the Atlantic cod including the biology, ecology, life histories, behaviour, commercial exploitation and conservation Not only is Atlantic cod one of the most valuable food fish in the world’s oceans, it is an important component of North Atlantic ecosystems and has been subject to much research into its biology, ecology and exploitation. After hundreds of years of exploitation, overfishing in the last half of the 20th Century caused many stocks to collapse, most famously the Northern cod stock off Newfoundland and Labrador, Canada. Since then, most cod stocks have been better researched and managed, but remain in a variety of states, from fully recovered to continued decline. This book, written by world experts, describes that research and management, and the importance of cod and its fisheries on North Atlantic cultures and economies, with impacts well beyond the range of the species. Atlantic Cod: Bio-Ecology of the Fish offers insightful chapter coverage of cod nomenclature, taxonomy, phylogeny and morphology; physiology and ecophysiology; reproduction and spawning behavior; early life history and pre-recruitment processes; migrations, movements and stock identity; feeding, growth and energetics; the place of cod in the ecosystem; the exploitation of cod through history and present day commercial fisheries and precautionary management for sustainable fisheries; impacts of climate change on cod biology and ecology; and the future of the species and its fisheries. Discusses the major commercial importance of Atlantic cod through history Provides a comprehensive treatment of the bio-ecology of the most researched and highly exploited fully marine species Examines how the decline (and recovery) of cod stocks is of great political and scientific interest An essential purchase for marine fisheries scientists Atlantic Cod: Bio-Ecology of the Fish is a vital book for all fisheries scientists, managers and fish biologists.
