Available in PDF, EPUB and Kindle. Book excerpt: Tracking Animal Migration with Stable Isotopes, Second Edition, provides a complete introduction to new and powerful isotopic tools and applications that track animal migration, reviewing where isotope tracers fit in the modern toolbox of tracking methods. The book provides background information on a broad range of migration scenarios in terrestrial and aquatic systems and summarizes the most cutting-edge developments in the field that are revolutionizing the way migrant individuals and populations are assigned to their true origins. It allows undergraduates, graduate students and non-specialist scientists to adopt and apply isotopes to migration research, and also serves as a useful reference for scientists. The new edition thoroughly updates the information available to the reader on current applications of this technique and provides new tools for the isotopic assignment of individuals to origins, including geostatistical multi-isotope approaches and the ways in which researchers can combine isotopes with routine data in a Bayesian framework to provide best estimates of animal origins. Four new chapters include contributions on applications to the movements of terrestrial mammals, with particular emphasis on how aspects of animal physiology can influence stable isotope values. Includes an animal physiology component that is an in-depth overview of the cautions and caveats related to this technique Covers marine and aquatic isoscapes and methods to track marine organisms for researchers trying to apply isotopic tracking to animals in these environments Features state-of-the-art statistical treatments for assignment and combining diverse datasets

Download or read book Stable Isotope Analyses of Bat Fur: Applications for Investigating North American Bat Migration written by Erin Elizabeth Fraser and published by . This book was released on 2011 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most North American bats undertake seasonal migrations and many aspects of bat migration are not well documented. Stable isotope analyses of animal tissues can elucidate migratory origin, but this technique has not been widely applied to bats. The objectives of this dissertation were i) to investigate North American bat migration using stable isotope analyses of fur and ii) to highlight some of the strengths and weaknesses of this analytical technique when applied to bat systems. I conducted stable hydrogen (D), carbon (13C), and nitrogen (15N) isotope analyses on fur samples from five bat species. First, I documented Dfur heterogeneity in summer resident populations of little brown bats (Myotis lucifugus), eastern red bats (Lasiurus borealis), hoary bats (Lasiurus cinereus) and silver-haired bats (Lasionycteris noctivagans). In some species, Dfur composition varied systematically within and among individual bats, age groups, species, sites, and over time. Future investigations should standardize fur collection according to the above variables and data from multiple species should not be pooled. Bats from proximate colonies can be discriminated using multiple stable isotopes and stable isotope correlations existed in some species. Multi-isotope studies may be used to detect population mixing. Second, I investigated the origins of fall migrant L. noctivagans and L. borealis passing through an Ontario migration monitoring station. There was no stable isotope evidence that migrant L. noctivagans originated from a wide range of latitudes, or that latitudinal origin varied with time or migrant wave. Lasiurus borealis stable isotope results were variable between years and further work is required before stable isotope results can be used to draw ecological conclusions about this species. Third, I investigated the annual migratory movements of tri-colored bats (Perimyotis subflavus), a presumed regional migrant. Stable hydrogen isotope results indicated that>30% of males migrated south in the fall. Only 16% of females migrated south and their movements were shorter than the male movements. Most of the migrants were captured at the northern and southern extremes of the species' range. I concluded that these bats engage in a pattern of partial and differential latitudinal migration that has previously not been described for this species.

This book was released on 2015 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: New technologies are allowing researchers to more accurately quantify migratory movement and stopover behavior for a variety of species, including bats. Better understanding of the spatial and temporal scale of migration can inform conservation decisions related to sensitivity of particular locations for migratory species, especially in the face of ongoing development and climate change. Improved quantification of movement corridors can lead to proactive strategies for conservation by prioritizing areas that facilitate movement. Using passive and active telemetry, we were able to identify movement patterns of long distance migrants from east to west along Lake Erie's western basin and determine stopover duration for Lasiurus borealis and Lasiurus noctivagans (5.6 and 1 days respectively) during spring migration. Bats were more likely to move east to west along the shoreline of Lake Erie as opposed to flying long distances over open water. Departures of migratory bats were more likely to occur on nights with higher barometric pressure, higher dew point, and a lower wind differential (difference between wind gust and sustained wind speed). In addition, we used stable isotope analysis of bat fur to learn more about the ecology of bats captured in the western basin of Lake Erie. We determined that big brown, silver-haired, and red bats were isotopically distinct in carbon and nitrogen, while migrant and resident eastern red bats (as determined by telemetry) were not. This study adds to our knowledge of bat migration and should be useful for future decisions related to conservation and management of natural resources within the western basin of Lake Erie.

This book was released on 2015-12-07 with total page 601 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on central themes related to the conservation of bats. It details their response to land-use change and management practices, intensified urbanization and roost disturbance and loss. Increasing interactions between humans and bats as a result of hunting, disease relationships, occupation of human dwellings, and conflict over fruit crops are explored in depth. Finally, contributors highlight the roles that taxonomy, conservation networks and conservation psychology have to play in conserving this imperilled but vital taxon. With over 1300 species, bats are the second largest order of mammals, yet as the Anthropocene dawns, bat populations around the world are in decline. Greater understanding of the anthropogenic drivers of this decline and exploration of possible mitigation measures are urgently needed if we are to retain global bat diversity in the coming decades. This book brings together teams of international experts to provide a global review of current understanding and recommend directions for future research and mitigation.

Download or read book Bat Ecology written by Thomas H. Kunz and published by University of Chicago Press. This book was released on 2005 with total page 799 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years researchers have discovered that bats play key roles in many ecosystems as insect predators, seed dispersers, and pollinators. Bats also display astonishing ecological and evolutionary diversity and serve as important models for studies of a wide variety of topics, including food webs, biogeography, and emerging diseases. In Bat Ecology, world-renowned bat scholars present an up-to-date, comprehensive, and authoritative review of this ongoing research. The first part of the book covers the life history and behavioral ecology of bats, from migration to sperm competition and natural selection. The next section focuses on functional ecology, including ecomorphology, feeding, and physiology. In the third section, contributors explore macroecological issues such as the evolution of ecological diversity, range size, and infectious diseases (including rabies) in bats. A final chapter discusses conservation challenges facing these fascinating flying mammals. Bat Ecology is the most comprehensive state-of-the-field collection for scientists and researchers.

Available in PDF, EPUB and Kindle. Book excerpt: 4.1.1 Demographic significance Confined populations grow more rapidly than populations from which dispersal is permitted (Lidicker, 1975; Krebs, 1979; Tamarin et at., 1984), and demography in island populations where dispersal is restricted differs greatly from nearby mainland populations (Lidicker, 1973; Tamarin, 1977, 1978; Gliwicz, 1980), clearly demonstrating the demographic signi ficance of dispersal. The prevalence of dispersal in rapidly expanding populations is held to be the best evidence for presaturation dispersal. Because dispersal reduces the growth rate of source populations, it is generally believed that emigration is not balanced by immigration, and that mortality of emigrants occurs as a result of movement into a 'sink' of unfavourable habitat. If such dispersal is age- or sex-biased, the demo graphy of the population is markedly affected, as a consequence of differ ences in mortality in the dispersive sex or age class. Habitat heterogeneity consequently underlies this interpretation of dispersal and its demographic consequences, although the spatial variability of environments is rarely assessed in dispersal studies.

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.
