Book Synopsis Conservation of Endangered Species in Captivity by : Edward F. Gibbons Jr.
Download or read book Conservation of Endangered Species in Captivity written by Edward F. Gibbons Jr. and published by State University of New York Press. This book was released on 1995-08-31 with total page 832 pages. Available in PDF, EPUB and Kindle. Book excerpt: This multi-disciplinary approach to conservation of endangered species in captivity is organized taxonomically and by scientific discipline. The seven taxonomic groups included are invertebrates; fish, reptiles and amphibians, birds, marine mammals, primates, and other mammals. Within each taxonomic group, four scientific disciplines are explored: conservation, reproductive physiology, behavior, and captive design. Conservation chapters summarize the status of the taxonomic group both in the wild and in captivity. Reviewed in the reproductive physiology chapters are anatomy, endocrinology and physiology for females and males of the taxonomic group. In the section on behavior the functions of captive animal research, the methods used, and the problems encountered are discussed. And, in examining captive design the authors provide a general historical outline of the philosophies, trends, and scientific issues for the targeted taxonomic group.

Book Synopsis North Pacific Right Whale Calling Behavior and Habitat Characterization in the Southeastern Bering Sea by : Lisa Marie Munger
Download or read book North Pacific Right Whale Calling Behavior and Habitat Characterization in the Southeastern Bering Sea written by Lisa Marie Munger and published by . This book was released on 2007 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "North Pacific right whales (Eubalaena japonica) are critically endangered due to intensive commercial whaling in the 1800s and illegal whaling in the 1960s. Currently the eastern subpopulation probably numbers in the dozens of animals, and little is known about their behavioral ecology. The majority of sightings within the past 50 years have been in the southeastern Bering Sea (SEBS), in shallow waters (200 m) over the continental shelf. Moored, passive acoustic recorders were deployed in the SEBS in 2001, 2002, 2004, and 2005 to monitor the middle shelf for right whale calls and recorded for 2 - 11 months per instrument. Deployments were at or near subsurface moorings that recorded oceanographic data including temperature, salinity, and chlorophyll fluorescence. Techniques were developed for efficiently detecting right whale calls in a large data set, and calling behavior was investigated on daily and seasonal scales. Acoustic properties of right whale calls and their propagation on the SEBS shelf were estimated and temporal patterns in right whale calling were examined in relation to oceanographic variables. Automated call detection was useful at guiding analysts to bouts of right whale calling and additional calls were found by manually searching. Right whales occurred in the SEBS as early as May and as late as December. Calling rates were significantly higher during darkness than during daylight, suggesting a relationship to behavior that may vary diurnally, such as foraging. Right whale call source levels were within ranges reported for other balaenid whale species, and calls propagated for long distances (100 km) on the SEBS middle shelf. Right whales were detected earlier in years with early ice retreat and a late spring bloom and intermittently throughout summer and fall in all years with recording effort. Peak right whale calling rates and the most days per month with calls were in late summer. We hypothesize that right whale occurrence is linked to environmental variables via bottom-up control on production and distribution of copepods, their primary prey. These results are relevant to conservation and form the basis for future investigations of right whale calling behavior and its relationship to habitat use"--Leaves xvi-xvii

Download or read book The Dusky Dolphin written by Bernd Würsig and published by Academic Press. This book was released on 2009-07-17 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Dusky Dolphin: Master Acrobat Off Different Shores covers various topics about the dusky dolphin, including its taxonomy, history and demography, ecology, and behavior. After introducing the dusky dolphin as a member of the genus Lagenorhynchus under the family Delphinidae, the book continues by describing its life history, its demographic patterns, and its role in the food web considering predation, parasitism, and competition. The book also includes chapters that discuss the interaction of the dusky dolphin with its habitats, such as the dusky dolphin’s sound production, its foraging at night and in daylight, its survival strategies in response to predator threats, the mating habits of New Zealand duskies, calf rearing, sexual segregation, and genetic relationships. Other chapters address the interaction of dusky dolphins with humans. This book offers information about dusky dolphins off Southern Africa and discussions about the patterns of sympatry in Lagenorhynchus and Cephalorhynchus. Finally, comparisons between dusky dolphins and great apes as large-brained mammals are also reviewed in this book. Only book fully devoted to the southern hemisphere "dusky" dolphin Heavily illustrated with charts, figures, tables, and all color photos Written by a cadre of experts intimately familiar with dolphin field work Written in an accurate yet accessible style for the scientist and natural historian alike

Available in PDF, EPUB and Kindle. Book excerpt: In this book, an international team of leading marine mammal scientists, with a remarkably diverse set of backgrounds and areas of expertise, lead you through a synthesis of current knowledge on baleen whales. Baleen whales are the largest animals ever to have lived on this planet. They also have the lowest and most intense voices on Earth, most likely evolved to take advantage of ocean acoustic transmission conditions so as to be detectable across ocean basins. Some baleen whales can live to be 150-200 years old. They migrate many thousands of kilometers between feeding and breeding areas. They produce songs and calls that serve as behavioral foundations for establishing, maintaining and expanding their cultural identities. To conclude that we know the behavioral limits of these large brained, long-lived animals would be naïve. As baleen whale scientists, we are still beginning to comprehend the enormous complexities and natural histories of these remarkable animals. Today, the fact that whales sing is known throughout much of the world. This awareness started 50 years ago with the publication and popularization of a collection of humpback song recordings that motivated research into baleen whale behavioral ethology. In this book’s chapters, a reader’s experiences will stretch from learning about baleen whale laryngeal anatomy associated with their different voices to learning about the vast ocean areas over which their voices can be heard and the emerging complexities of their culturally defined societies. These are accompanied by chapters on the fundamental ethological contexts of socializing, migrating, and foraging. Two common themes permeate the book. One theme highlights the phenomenal increase in scientific knowledge achieved through technological advancements. The other theme recognizes the impacts of human-made activities on ocean acoustic environments and the resultant influences on the health and survival of individual whales and their populations. Although the book is intentionally ambitious in its scope, as scientists, we fully recognize that baleen whale science is still in its infancy. Many profound revelations await discovery by cohorts of young, multi-talented explorers, some of whom are stretching their wings in this volume and some of whom are reading these scientific stories for the first time.

Download or read book Distribution Ecology written by Marcelo Hernán Cassini and published by Springer Science & Business Media. This book was released on 2013-03-02 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together a set of approaches to the study of individual-species ecology based on the analysis of spatial variations of abundance. Distribution ecology assumes that ecological phenomena can be understood when analyzing the extrinsic (environmental) or intrinsic (physiological constraints, population mechanisms) that correlate with this spatial variation. Ecological processes depend on geographical scales, so their analysis requires following environmental heterogeneity. At small scales, the effects of biotic factors of ecosystems are strong, while at large scales, abiotic factors such as climate, govern ecological functioning. Responses of organisms also depend on scales: at small scales, adaptations dominate, i.e. the ability of organisms to respond adaptively using habitat decision rules that maximize their fitness; at large scales, limiting traits dominate, i.e., tolerance ranges to environmental conditions.

Book Synopsis Habitat Use of Calling Baleen Whales in the Southern California Current Ecosystem by : Elizabeth Tram Anh Vu

This book was released on 2015 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: The extent to which temporal, spatial, environmental, and physiological factors influence baleen whale acoustic occurrence was investigated in the southern California Current Ecosystem, a highly productive, upwelling-driven ecosystem that hosts a large abundance of top predators. By combining data sets from ten years of passive acoustic monitoring and concurrent environmental sampling, this dissertation presents detailed intra-annual and mesoscale spatial patterns previously unknown. Analyses of temporal acoustic patterns revealed different acoustic occupancy by three species: blue whale (Balaenoptera musculus), humpback whale (Megaptera novaeangliae), and fin whale (Balaenoptera physalus). The temporal separation between blue whale feeding and breeding call types showed a shift between behavioral states throughout the year. The temporal separation between blue and humpback whale reproductive calls showed different displays of reproductive calling behavior despite their overlapping migratory and seasonal reproductive cycles. Spatial patterns revealed different onshore and offshore occupancy, dependent on season, for each species. The reconciliation between acoustic and visual seasonal abundance demonstrated an increase in individual-level acoustic reproductive display during or approaching the mating season of each species. Analyses of habitat factors on call types from each species identified association of seasonality, bathymetry, sea surface temperature, and mixed layer depth with calling behavior. Generalized additive mixed models of acoustic calling revealed significant responses to seasonality and bathymetry at three different spatial scales, indicating the importance of these factors in explaining baleen whale distribution at broad scales. Lastly, a possible physiological driver of acoustic behavior was investigated by quantifying seasonal hormone concentrations in humpback whale blubber. The results of this research advance scientific understanding of yearlong acoustic cetacean occurrence in a productive oceanographic habitat and provide additional insight into the reproduction and migration of these species.
