Book Synopsis The North American Sea Ducks by : Paul Johnsgard
Download or read book The North American Sea Ducks written by Paul Johnsgard and published by Lulu.com. This book was released on 2016-11-09 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 21 species of sea ducks are one of the larger subgroups (Tribe Mergini) of the waterfowl family Anatidae, and the 16 species (one historically extinct) that are native to North America represent the largest number to be found on any continent, and also the largest number of endemic sea duck species native to any continent. Although generally not important as game birds, the sea ducks include some economically important birds such as the eiders, the basis for the Arctic eiderdown industry and a historically important food source for some Native American cultures. They also include what is probably the most northerly breeding species of all waterfowl and an icon of Arctic bird life, the long-tailed duck. The sea ducks also include species having some of the most complex and diverse pair-forming postural and acoustic displays of all waterfowl (goldeneyes and bufflehead), and some of the deepest diving species of all waterfowl (scoters and long-tailed duck). Sea ducks are highly prone to population disasters caused by oil spills and other water contaminants and, like other seabirds, are among the first bird groups that are being affected by current global warming trends in polar regions. This book is an effort to summarize succinctly our current knowledge of sea duck biology and to provide a convenient survey of the vast technical literature on the group, with over 900 literature references. It also includes 90,000 words of text (more than 40 percent of which is new), 15 updated range maps, 11 black & white and 20 color photographs, over 30 ink drawings, and nearly 150 sketches. Lastly, the North American sea ducks include the now extinct Labrador duck, the only northern hemisphere waterfowl species to have gone extinct in modern times. I have gratefully reprinted a Labrador duck watercolor by Sir Peter Scott. Considering recent population crashes in other sea ducks, such as the Steller's eider and spectacled eider, it should also offer a sobering reminder of the fragility of our natural world and its inhabitants, including us.

Book Synopsis Conservation Palaeobiology of Marine Ecosystems by : R. Nawrot
Download or read book Conservation Palaeobiology of Marine Ecosystems written by R. Nawrot and published by Geological Society of London Special Publications. This book was released on 2023-07-03 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conservation palaeobiology tracks the history of ecosystems based on the fossil record to guide conservation decisions and contribute to the theoretical foundations of conservation biology. The accelerating pace of global change requires better understanding of the long-term resilience and adaptive capacities of ecosystems. Fossil assemblages in outcrops and cores, together with surface accumulations of skeletal remains, represent unique archives of past ecosystem dynamics and baseline community states prior to anthropogenic impacts. However, as biological data retrieved from fossil and death assemblages cannot be treated in isolation, conservation palaeobiology integrates palaeontological and geological tools to account for the nature of the stratigraphic record. This volume brings together studies that demonstrate how combining marine palaeoecological records with other types of geohistorical data (taphonomic, sedimentological, geochronological, geochemical) can inform biodiversity conservation and ecosystem management. The papers highlight novel approaches and challenges in applying geohistorical data to conservation problems, discuss the limitations imposed by time averaging, and offer both deep- and near-time perspectives on conservation palaeobiology of marine ecosystems.

Book Synopsis Avian Malaria and Related Parasites in the Tropics by : Diego Santiago-Alarcon
Download or read book Avian Malaria and Related Parasites in the Tropics written by Diego Santiago-Alarcon and published by Springer Nature. This book was released on 2020-10-19 with total page 575 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Tropics are home to the greatest biodiversity in the world, but tropical species are at risk due to anthropogenic activities, mainly land use change, habitat loss, invasive species, and pathogens. Over the past 20 years, the avian malaria and related parasites (Order: Haemosporida) systems have received increased attention in the tropical regions from a diverse array of research perspectives. However, to date no attempts have been made to synthesize the available information and to propose new lines of research. This book provides such a synthesis by not only focusing on the antagonistic interactions, but also by providing conceptual chapters on topics going from avian haemosporidians life cycles and study techniques, to chapters addressing current concepts on ecology and evolution. For example, a chapter synthesizing basic biogeography and ecological niche model concepts is presented, followed by one on the island biogeography of avian haemosporidians. Accordingly, researchers and professionals interested in these antagonistic interaction systems will find both an overview of the field with special emphasis on the tropics, and access to the necessary conceptual framework for various topics in ecology, evolution and systematics. Given its conceptual perspective, the book will appeal not only to readers interested in avian haemosporidians, but also to those more generally interested in the ecology, evolution and systematics of host-parasite interactions.
Book Synopsis Avian Malaria Parasites and other Haemosporidia by : Gediminas Valkiunas
Download or read book Avian Malaria Parasites and other Haemosporidia written by Gediminas Valkiunas and published by CRC Press. This book was released on 2004-10-28 with total page 946 pages. Available in PDF, EPUB and Kindle. Book excerpt: When studying the effects of parasites on natural populations, the avian haematozoa fulfills many of the specifications of an ideal model. Featuring a multitude of tables and illustrations, Avian Malaria Parasites and Other Haemosporidia summarizes more than a century of research on bird haemosporidians. For a long time, bird blood parasites served as important models in studying human diseases. Although now largely replaced, the wealth of data and research remain. With chapters addressing life cycles and morphology, pathogenicity, ultrastructure, geographical distribution, and illustrated keys to all known species of the parasites, this book is a masterful assessment of the biology of bird haemosporidian parasites.
Book Synopsis Responding to Oil Spills in the U.S. Arctic Marine Environment by : National Research Council
Download or read book Responding to Oil Spills in the U.S. Arctic Marine Environment written by National Research Council and published by National Academies Press. This book was released on 2014-08-01 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: U.S. Arctic waters north of the Bering Strait and west of the Canadian border encompass a vast area that is usually ice covered for much of the year, but is increasingly experiencing longer periods and larger areas of open water due to climate change. Sparsely inhabited with a wide variety of ecosystems found nowhere else, this region is vulnerable to damage from human activities. As oil and gas, shipping, and tourism activities increase, the possibilities of an oil spill also increase. How can we best prepare to respond to such an event in this challenging environment? Responding to Oil Spills in the U.S. Arctic Marine Environment reviews the current state of the science regarding oil spill response and environmental assessment in the Arctic region north of the Bering Strait, with emphasis on the potential impacts in U.S. waters. This report describes the unique ecosystems and environment of the Arctic and makes recommendations to provide an effective response effort in these challenging conditions. According to Responding to Oil Spills in the U.S. Arctic Marine Environment, a full range of proven oil spill response technologies is needed in order to minimize the impacts on people and sensitive ecosystems. This report identifies key oil spill research priorities, critical data and monitoring needs, mitigation strategies, and important operational and logistical issues. The Arctic acts as an integrating, regulating, and mediating component of the physical, atmospheric and cryospheric systems that govern life on Earth. Not only does the Arctic serve as regulator of many of the Earth's large-scale systems and processes, but it is also an area where choices made have substantial impact on life and choices everywhere on planet Earth. This report's recommendations will assist environmentalists, industry, state and local policymakers, and anyone interested in the future of this special region to preserve and protect it from damaging oil spills.
