This book was released on 2018 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this dissertation, I use phenotypic data on age and life-history trait expression from long-lived Nazca boobies (Sula granti, a seabird) breeding in Galápagos to understand cause and effect relationships underlying variation in reproduction, survival, and ageing patterns. In the first chapter, age-specific demographic data spanning the loss of a preferred prey item were used to forecast the response of the Nazca booby population to future exclusion of the key prey species (sardines, Sardinops sagax), by ocean warming, from the foraging envelope. Breeding success was dramatically reduced when sardines were not available. Adult female survival increased, but not enough to keep the population growth rate from falling below 1, indicating a shrinking population. Population growth may not recover because predicted ocean warming around Galápagos should displace sardines permanently from the boobies' island-constrained foraging range. In the second chapter, I test the expectation, made by the life history theories of ageing, that increased senescence should follow relatively high reproductive effort. In Nazca boobies, females recruit earlier and breed more often, predicting more intense actuarial and reproductive senescence in that sex. Females did show stronger senescence for survival and offspring production, but a causal link between sex differences in early reproduction and sex-differences in ageing was not supported because, within each sex, individual reproductive effort positively predicted late-life performance. Absent evidence for early reproductive effort trading off with late-life performance, patterns of sex differences in senescence may result from age- and condition-dependent mate-choice interacting with this population’s male-biased sex ratio and mate rotation. Finally, in the third chapter, I show that age and current environment may interact to determine breeding responses to environmental change. Young and old Nazca booby females had lower performance than middle-age birds for all reproductive traits, and these age effects sometimes increased under a challenging environment. Environmental quality was assessed with respect to the El Niño-Southern Oscillation (ENSO). Surprisingly, Nazca booby responses to the ENSO were not in step with ENSO-forced changes in primary productivity within the boobies' foraging envelope. Instead, trophic interactions with subsurface predators may influence Nazca booby responses to oceanographic variables. As a whole, this dissertation shows the ability of long-term, individual-based, ecological studies to address important topics from ecology and evolutionary biology, including ageing, trophic interactions, and the responses of individuals and populations to environmental change.

Book excerpt: The Encyclopedia of Animal Behavior, Three Volume Set has engaged with great success the efforts of many of the best behavioral biologists of the 21st century. Section editors drawn from the most accomplished behavioral scientists of their generation have enrolled an international cast of highly respected thinkers and writers all of whom have taken great care and joy in illuminating every imaginable corner of animal behavior. This comprehensive work covers not only the usual topics such as communication, learning, sexual selection, navigation, and the history of the field, but also emerging topics in cognition, animal welfare, conservation, and applications of animal behavior. The large section on animal cognition brings together many of the world's experts on the subject to provide a comprehensive overview of this rapidly developing area. Chapters relating to animal welfare give a full view of behavioral interactions of humans with companion animals, farm animals, and animals in the wild. The key role of animal behavior in conservation biology receives broad attention, including chapters on topics such as the effects of noise pollution, captive breeding, and how the behavioral effects of parasites interacts with conservation issues. Animal behavior in environmental biology is highlighted in chapters on the effects of endocrine disruptors on behavior and a large number of chapters on key species, such as wolves, chimpanzees, hyenas and sharks. Clear, accessible writing complements a wealth of information for undergraduate college students about the essential concepts of animal behavior and the application of those concepts across the field. In-depth coverage of concepts, methods, and exemplar organisms serves the needs of graduate students and professionals in the field. From the use of behavior in assessing the welfare of pigs to the social behavior of insects, from animal empathy to bat brains, this authoritative reference, with its in-depth introductory articles, rich array of illustrations, interactive cross-referenced links, and numerous suggested readings, can guide the student or the professional to an expanded appreciation of the far-flung world of animal behavior. An invaluable tool for teaching and a source of enrichment and detail for any topic covered in an animal behavior course, the Encyclopedia of Animal Behavior is the definitive reference work in its field and will be for years to come. Comprehensive work which covers the usual topics along with emerging areas of animal behavior This encyclopedia contains clear, accessible writing and is well illustrated, including an online video, complimenting a wealth of information As an online reference, this work will be subject to period updating. This ensures that the work always remains current Contains in-depth introductions to the material that make each well-illustrated section come alive with the best the new content the discipline has to offer Glossary includes a compendium of behavioral terms that form a succinct mosaic of virtually every concept and phenomenon related to animal behavior Section editors, drawn from around the world, represent the best and the brightest among today's behavioral biologists and have recruited a broad range of internationally recognized experts Editors-in-Chief are experienced scientists and writers who between them have authored or edited eight books and teach courses in animal behavior at their respective universities

This book was released on with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the great challenges in ecophysiology is linking physiological measures in wild animal populations with changes in individual fitness. Physiological variables that indicate nutritional state, stress, disease, or injury are used extensively in veterinary practice and captive settings to assess the health and likelihood of reproductive success of many animals. The development and refinement of sampling methods that limit disturbance of animals, coupled with advancements in analytical methods have allowed researchers to begin to examine the relevance of these physiological parameters in wild animals for predicting population trends and response to environmental perturbations. However, despite extensive research in this field, consistent correlations between fitness and/or population health and physiological measures remain rare.

Book excerpt: This book provides the first collection of chapters written by scientists who have contributed to the understanding of disease ecology in the Galapagos Islands, an iconic and historic natural site. The Galapagos Archipelago straddles the equator in the eastern Pacific Ocean, almost 1000 km off the coast of Ecuador, and includes 13 major islands, numerous smaller satellite islands, and many more even smaller islets. The wildlife on the Galapagos Islands today represents one of the best-preserved wild communities of plants and animals in the world, owing to the location of the islands at the intersection of major ocean currents, the commitment by Ecuador for the vast majority of the area to be left undeveloped, and the protection provided by the Galapagos National Park. Most of the animal species in Galapagos are endemic, occurring nowhere else. But they are descendants of ancestors that colonized earlier, and then, isolated from their mainland origins, evolved into forms that are recognized as distinct today. Since 2001, many of the authors of this book have been part of a four-institution partnership investigating the threats posed by pathogens to Galapagos avifauna. They approach the topic of disease ecology in a novel manner, starting with the history of arrival of both the birds themselves and the pathogens. This synthetic approach requires the integration of themes from veterinary medicine, epidemiology, population genetics, and phylogenetics.

Available in PDF, EPUB and Kindle. Book excerpt: Detecting physiological decline in old age that underlies declines in survival and reproduction in a wild population can be challenging. This applies especially to long-lived species that require marking around birth in order to recognize elderly individuals perhaps decades later. Here, we used bite force of known-age, long-lived Nazca boobies (Sula granti) as a functional measure of muscle strength. Elderly Nazca boobies show declining survival and reproduction (senescence). Identifying muscle strength as a candidate physiological contributor to this decline, we predicted a parallel age-related decline in muscle strength from middle to old age. Data were collected from 349 nonbreeding adults using a force transducer during the breeding season in November 2017 on Isla Española, Galápagos. Both sexes showed the predicted drop in bite force in the second half of the lifespan. The decline began at a younger age in females, in parallel with sex-specific schedules of actuarial and reproductive senescence documented in an earlier study. Understanding which physiological traits show decline in old age contributes to an integrative portrait of the senescence process in wild animals.
