Book Synopsis Causes and Consequences of Sex Ratio Bias in Nazca Boobies (Sula Granti) by : Terri J. Maness
Download or read book Causes and Consequences of Sex Ratio Bias in Nazca Boobies (Sula Granti) written by Terri J. Maness and published by . This book was released on 2008 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nazca boobies are socially and genetically monogamous, long-lived pelagic seabirds with bi-parental care and similar parental roles. A large colony on the island of Española, Galápagos has been the focus of long-term reproductive and demographic studies. The adult sex ratio at this colony has been significantly male biased for more than twenty years. Knowledge of the ontogeny of this bias provides critical context that allows proper framing of hypotheses regarding parental sex allocation, the relative reproductive value of sons and daughters, mating systems, individual fitness and endangered species management. Nazca booby parents might adaptively alter the sex of their offspring according to current environmental or demographic conditions, or sex-specific mortality may occur in poor food years. Genetic sex determination of nestlings and fledglings showed that these processes could not account for the male-biased adult sex ratio in this population. Instead, the sex ratio bias arose after the period of parental care ended, during the juvenile/subadult stage between fledging and return to the colony. The deficit of female recruits is apparently a consequence of sex-specific post-fledging mortality. This finding has important implications for mate competition. The proportional representation of males among the adults ready to mate in a population at a given moment is a central concept in explaining variation in sex roles, the intensity of mating competition, and mate choice. Given the extensive period (approximately six months) of parental care in Nazca boobies, both males and females should benefit from choosiness in mate selection. The sex ratio bias in this population should allow females to choose the best available partner from a pool of potential mates. Behavioral observations and analysis of long-term mating patterns revealed that divorce was more common in this population than is typically expected for monogamous seabirds. Costs of reproduction provided a basis for females to adaptively switch mates, replacing a temporarily depleted male for a current non-breeder in better condition. Behavioral observations revealed that mate choice and divorce were driven primarily by female choice. Females appeared to use several long-term indicators of health and nutritional status to distinguish among potential mates. Males selected as mates were in better body condition, had lower circulating immunoglobulin G levels, and, as a group, had lower variance in serum albumin concentration than did unselected males. This body of work included the most complete documentation of the ontogeny of the sex ratio across the lifespan for any wild bird species, provided evidence for a previously undescribed mating system, uniquely investigated the behavior of mated pairs and non-breeding adults prior to divorce, and was the first study to examine the morphological and hematological parameters of individuals during the process of mate selection in a wild population.

Download or read book Seabird Ecology written by R. W. Furness and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last few years there has been an excltmg upsurge in seabird research. There are several reasons for this. Man's increased ex ploitation of natural resources has led to a greater awareness of the potential conflicts with seabirds, and of the use of seabirds to indicate the damage we might be doing to our environment. Many seabird populations have increased dramatically in numbers and so seem more likely to conflict with man, for example through competition for food or transmission of diseases. Oil exploration and production has resulted in major studies of seabird distributions and ecology in relation to oil pollution. The possibility that seabirds may provide information on fish stock biology is now being critically investigated. Some seabird species have suffered serious declines in numbers and require conservation action to be taken to reduce the chances that they will become extinct. This requires an understanding of the factors determining their population size and dynamics.

Book Synopsis Conservation of Tropical Birds by : Navjot S. Sodhi
Download or read book Conservation of Tropical Birds written by Navjot S. Sodhi and published by John Wiley & Sons. This book was released on 2011-02-23 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conservation of Tropical Birds has been written by four conservation biologists whose expertise spans all the tropical regions of the world. It is the first book to cover all the major issues in tropical bird conservation. Current problems faced by tropical bird conservationists are summarised and potential solutions outlined based on the results of case studies. Birds are key indicators of ecosystem health, and such a well-studied group of organisms, that they provide an excellent lens through which to examine global conservation problems caused by phenomena such as climate change, declines in ecosystem services, habitat loss, fires, overexploitation, and invasive species. Therefore, the book also provides an engaging synopsis of the general issues in conservation and the problems faced by other wildlife. This book serves as an important resource and companion to all people interested in observing and conserving birds in the tropics and elsewhere.
Book Synopsis Science and Conservation in the Galapagos Islands by : Stephen J. Walsh
Download or read book Science and Conservation in the Galapagos Islands written by Stephen J. Walsh and published by Springer Science & Business Media. This book was released on 2012-12-05 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this launch of the Galapagos series, this book provides a broad “framing” assessment of the current status of social and ecological systems in the Galapagos Islands, and the feedback that explicitly links people to the environment. It also highlights the challenges to conservation imposed by tourism in the Galapagos Islands and the attendant migration of people from mainland Ecuador to service the burgeoning tourism industry. Further, there is an emphasize on the status of the terrestrial and marine environments that form the very foundation of the deep attraction to the Islands by tourists, residents, scholars, and conservationists.

Book Synopsis Tidal Mixing and Plankton Dynamics by : Malcolm J. Bowman
Download or read book Tidal Mixing and Plankton Dynamics written by Malcolm J. Bowman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book represents an outgrowth of an interdisciplinary session held at the Seventh International Estuarine Research Federation Conference held at Virginia Beach, Virginia, OCLober 1983. At that meeting, the participants agreed to contribute to and develop a monograph entitled "Tidal Mixing and Plankton Dynamics" by inviting an expanded group of authors to contribute chapters on this theme. The emphasis would be to review and summarize the considerable body of knowledge that has accumulated over the last decade or so on the fundamental role tidal mixing plays in energetic shallow seas and estuaries in stimulating and controlling biological production. We have attempted to provide a mix of contributions, composed of reviews of the state-of-the-art, reports on current research activi ties, summaries of the design and testing of a new generation of innovative instruments for biological and chemical sampling and sorting, and some imaginative ideas for future experiments on stimulated mixing in continental shelf seas. We encouraged the contributors to present critical and thought provoking assessments of current wisdom specifying the sorts of techniques and observational strategies needed to validate the various hypotheses linking physical structure, mixing and circulation to plankton biomass and production. We hope this volume will appeal to incoming research students and established scholars alike. We certainly have enjoyed working with all the authors in compiling this book. We thank the numerous scientists who have served as reviewers, P. Boisvert for typing the manuscripts and W. Bellows for proofreading.
Book Synopsis Sexual Segregation in Vertebrates by : Kathreen Ruckstuhl
Download or read book Sexual Segregation in Vertebrates written by Kathreen Ruckstuhl and published by Cambridge University Press. This book was released on 2005 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: Males and females of many species can, and do, live separately for long periods of time. This sexual segregation is widespread and can be on social, spatial or habitat scales. An understanding of sexual segregation is important in the explanation of life history and social preference, population dynamics and the conservation of rare species. Sexual Segregation in Vertebrates explores the reasons why this behaviour has evolved and what factors contribute to it.
