Download or read book Shorebird Ecology Conservation and Management written by Dr. Mark A. Colwell and published by Univ of California Press. This book was released on 2010-11-16 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shorebirds are model organisms for illustrating the principles of ecology and excellent subjects for research. Their mating systems are as diverse as any avian group, their migrations push the limits of endurance, and their foraging is easily studied in the open habitats of estuaries and freshwater wetlands. This comprehensive text explores the ecology, conservation, and management of these fascinating birds. Beginning chapters examine phylogenetic relationships between shorebirds and other birds, and cover shorebird morphology, anatomy, and physiology. A section on breeding biology looks in detail at their reproductive biology. Because shorebirds spend much of their time away from breeding areas, a substantial section on non-breeding biology covers migration, foraging ecology, and social behavior. The text also covers shorebird demography, population size, and management issues related to habitat, predators, and human disturbances. Throughout, it emphasizes applying scientific knowledge to the conservation of shorebird populations, many of which are unfortunately in decline.
Download or read book Mudflat Ecology written by Peter G. Beninger and published by Springer. This book was released on 2019-02-13 with total page 429 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intertidal mudflats are distinct, highly-productive marine habitats which provide important ecosystem services to the land-sea interface. In contrast to other marine habitats, and despite a large body of primary scientific literature, no comprehensive synthesis exists, such that the scattered knowledge base lacks an integrated conceptual framework. We attempt to provide this synthesis by pulling together and contextualizing the different disciplines, tools, and approaches used in the study of intertidal mudflats. The editor pays particular attention to relationships between the various components of the synthesis, both at the conceptual and the operational levels, validating these relationships through close interaction with the various authors.
Download or read book The Ecology and Conservation of Migratory Shorebirds Along the East Asian Australasian Flyway written by Tong Mu and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Investigating the factors shaping the diversified patterns of habitat use and long-distance movements of migratory species is not only fundamental to understanding the ecology and evolution of migration, but also has direct conservation implications to more effectively preserving globally declining migrant populations. In my dissertation, I used coastal shorebirds as the focal species, and investigated how an ecological understanding in their habitat preferences, habitat quality, as well as migratory movement and migration strategies may inform conservation practices for these rapidly declining species at different scales.In Chapter 1, I quantified the spatiotemporal distribution patterns of local shorebird populations, and found that the upper tidal flats provided more than 70% of the cumulative foraging time for most shorebird populations, disproportionately greater than the size of this stretch of tidal flat. The results could explain why the population decline rates of many shorebird species have far exceeded the overall rate of tidal habitat loss, highlighting the importance of protecting upper tidal flats for the conservation of migratory shorebirds.In Chapter 2, I devised an entirely field-based approach to quantitatively evaluate the quality of a major stopover site for the declining Red Knot. I estimated that the Nanpu tidal flat was operating below, but remarkably close to, its carrying capacity. This approach needs to be applied more broadly to more accurately evaluate how the Red Knot population may respond to changes in habitat quality.In Chapters 3 and 4, I tracked the annual migration of two small shorebird species, Red-necked Stint and Red-necked Phalaropes, using light-level geolocators. Tracking the annual movement of migratory species not only sheds light on the species-specific migration patterns, but also contributes to understanding the factors shaping migration strategies and the vulnerability of these strategies to different anthropogenic threats.Taken together, this dissertation investigated some of the key ecological questions regarding the migration and stopover ecology of migratory, with direct conservation implications in identifying the factors that affect the vulnerability of migratory species to various anthropogenic threats at different scales.
Download or read book Biology and Conservation of Horseshoe Crabs written by John T. Tanacredi and published by Springer Science & Business Media. This book was released on 2009-06-04 with total page 658 pages. Available in PDF, EPUB and Kindle. Book excerpt: Horseshoe crabs, those mysterious ancient mariners, lured me into the sea as a child along the beaches of New Jersey. Drawn to their shiny domed shells and spiked tails, I could not resist picking them up, turning them over and watching the wondrous mechanical movement of their glistening legs, articulating with one another as smoothly as the inner working of a clock. What was it like to be a horseshoe crab, I wondered? What did they eat? Did they always move around together? Why were some so large and others much smaller? How old were they, anyway? What must it feel like to live underwater? What else was out there, down there, in the cool, green depths that gave rise to such intriguing creatures? The only way to find out, I reasoned, would be to go into the ocean and see for myself, and so I did, and more than 60 years later, I still do.

Download or read book Site Selection by Migratory Shorebirds in Oregon Estuaries Over Broad and Fine Spatial Scales written by and published by . This book was released on 2012 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many migratory shorebirds rely on estuaries as stop-over sites to refuel during migration, and the loss of stop-over sites is a primary threat to shorebird populations on the West Coast of the United States (e.g. Calidris alpina pacifica, C. mauri). Conservation and research has focused on the largest of these sites; however, smaller estuaries also host thousands of migratory shorebirds. Furthermore, the reasons for site selection are largely unknown. Estuarine inter-tidal microhabitats are non-uniform and both abiotic and biotic factors may serve as predictors of whether an abundance of shorebirds will use a site. I investigated shorebird site selection on broad and fine scales within Oregon estuaries. To identify factors that relate to shorebird abundance on large spatial scales, I compiled shorebird abundance data from estuaries throughout the Pacific Northwest as well as data on site quality factors. To investigate site selection on a finer scale I measured shorebird abundance, habitat characteristics, and food resources―invertebrates and a newly considered source, biofilm―within two Oregon estuaries during the fall migration period. Finally, I examined whether channels are preferentially used by foraging Calidrid shorebirds by conducting observations during the spring migration. I investigated whether channels may be superior foraging habitat possibly because prey are more abundant, are found at shallower depths, or because sediments are more penetrable (increasing the opportunity for shorebird probing) by taking infauna cores and measuring force required to probe in the sediment at channel and open mudflat sites. Among estuaries, shorebird densities in spring were best predicted by estuary size, as opposed to the amount of any one habitat. During fall migration, the amount of grassland in the surrounding watershed was also a good predictor, pointing to the probable importance of roost sites as well as feeding grounds. The amount of infauna also related to the density of shorebirds using a site. Within estuaries, shorebird distribution in the inter-tidal region was not generally predicted by prey abundance. Channels were used preferentially by shorebirds, and infauna abundance along channels was greater than in the surrounding mudflats. The more penetrable sediments of the channel also made it easier for shorebirds to probe and capture prey. Identification of these large-scale and fine-scale factors that influence site quality for migratory shorebirds will assist land and wildlife managers' efforts to protect these species.
Download or read book The Population Ecology and Conservation of Charadrius Plovers written by Mark A. Colwell and published by CRC Press. This book was released on 2019-04-26 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 40 or so species of beach-loving plovers (genus Charadrius) comprise a diverse group of shorebirds found around the world. Most of these species are challenged by changing climates and other human-related development activities, yet they provide key insights into basic ecological and evolutionary processes. The expert international contributors take a comparative approach, presenting examples from many worldwide plover studies and synthesizing the group’s most pressing and important topics. The book further presents an emphasis on full life-cycle biology, including the importance of examining migratory connectivity issues, even for non-migratory plovers.

Available in PDF, EPUB and Kindle. Book excerpt: This open access book reviews the importance of ecological functioning within rangelands considering the complex inter-relationships of production agriculture, ecosystem services, biodiversity, and wildlife habitat. More than half of all lands worldwide, and up to 70% of the western USA, are classified as rangelands—uncultivated lands that often support grazing by domestic livestock. The rangelands of North America provide a vast array of goods and services, including significant economic benefit to local communities, while providing critical habitat for hundreds of species of fish and wildlife. This book provides compendium of recent data and synthesis from more than 100 experts in wildlife and rangeland ecology in Western North America. It provides a current and in-depth synthesis of knowledge related to wildlife ecology in rangeland ecosystems, and the tools used to manage them, to serve current and future wildlife biologists and rangeland managers in the working landscapes of the West. The book also identifies information gaps and serves as a jumping-off point for future research of wildlife in rangeland ecosystems. While the content focuses on wildlife ecology and management in rangelands of Western North America, the material has important implications for rangeland ecosystems worldwide.

Download or read book Birds of Two Worlds written by Russell Greenberg and published by JHU Press. This book was released on 2005-05-02 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: For centuries biologists have tried to understand the underpinnings of avian migration: where birds go and why, why some migrate and some do not, how they adapt to a changing environment, and how migratory systems evolve. Twenty-five years ago the answers to many of these questions were addressed by a collection of migration experts in Keast and Morton's classic work Migrant Birds in the Neotropics. In 1992, Hagan and Johnston published a follow-up book, Ecology and Conservation of Neotropical Migrant Landbirds. In Birds of Two Worlds Russell Greenberg and Peter Marra bring together the world's experts on avian migration to discuss its ecology and evolution. The contributors move the discussion of migration to a global stage, looking at all avian migration systems and delving deeper into the evolutionary foundations of migratory behavior. Readers interested in the biology, behavior, ecology, and evolution of birds have waited a decade to see a worthy successor to the earlier classics. Birds of Two Worlds will complete the trilogy and become indispensable for ornithologists, evolutionary biologists, serious birders, and public and academic libraries.
Download or read book Connectivity Conservation written by Kevin R. Crooks and published by Cambridge University Press. This book was released on 2006-11-02 with total page 675 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the biggest threats to the survival of many plant and animal species is the destruction or fragmentation of their natural habitats. The conservation of landscape connections, where animals, plants, and ecological processes can move freely from one habitat to another, is therefore an essential part of any new conservation or environmental protection plan. In practice, however, maintaining, creating, and protecting connectivity in our increasingly dissected world is a daunting challenge. This fascinating volume provides a synthesis on the current status and literature of connectivity conservation research and implementation. It shows the challenges involved in applying existing knowledge to real-world examples and highlights areas in need of further study. Containing contributions from leading scientists and practitioners, this topical and thought-provoking volume will be essential reading for graduate students, researchers, and practitioners working in conservation biology and natural resource management.
