Available in PDF, EPUB and Kindle. Book excerpt: This book integrates three decades of owl monkey research conducted since 1994 when the first and only book focused on the genus Aotus was published. Owl monkeys were one of the least understood primates then; knowledge from wild populations was only beginning to emerge and there had been some substantial research in colonies of captive individuals. The situation is very different today. Research on captive owl monkeys has continued to develop, with valuable contributions to the health and medical sciences. And there is now enough information on the behavior, ecology, conservation, and biogeography of the genus that merits a synthesis. The book synthesizes new field data on the biogeography, behavioral ecology, circadian biology, population biology and demography spanning their entire continental range from Panamá to Argentina. It includes theoretical perspectives drawn from evolutionary biology, biological anthropology, anatomy, morphology and physiology, genetics, endocrinology and conservation biology to examine a specic set of adaptations that have allowed owl monkeys to exploit the nocturnal niche while functioning in a pair-living sexually monogamous system with remarkable patterns of paternal care. The author, with 30 years of research experience with both captive and wild primates, has directed the longest project on any owl monkey species and has conducted extensive original research on their biology, adaptive radiation and behavioral ecology. His expertise and published record on both wild populations and laboratory colonies makes this book one of a kind; it presents information from both captive and wild primates and explores questions through the integration of both approaches. The volume offers some additional features that make it novel in its approach: (1) brings together a combination of senior researchers who during four decades have established captive owl monkeys as a system of study with a new generation of younger scientists who have, for the last 10-20 years, been spearheading their study in the wild, (2) presents the work of a remarkably diverse range of authors representing all countries where owl monkeys are present, as well as researchers from the U.S and Europe, and (3) offers “synthesis” chapters; in doing so, it will surely become a reference book for those specifically drawn to owl monkeys, as well as for those interested in the research topics that are covered.

Available in PDF, EPUB and Kindle. Book excerpt: Research in biology and all basic sciences has undergone profound transformations in recent decades. We have seen the development of extremely sophisticated techniques, allowing us to study, in an objective manner, questions that were still considered science fiction at the end of the 20th century. All of this has allowed us to develop an in-depth knowledge of vast subjects, such as the biology of the brain, for example. Fifty Years of Evolution in Biological Research presents a panorama of these different technical advances. However, at the same time, there has been an increase in the number of constraints on researchers, a monetization of research and a correlative pressure to continually publish in more prestigious journals. This has resulted in a certain degradation of the quality of research activity. This book analyzes this evolution and proposes solutions.

This book was released on 2017-04-10 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our world and bodies are becoming increasingly polluted with chemicals capable of interfering with our hormones and thus, possibly, our present and future neural and mental health. As authors Heather Patisaul and Scott Belcher outline, there is a large lack of data and evidence in this causal relationship, which begs a need for further study to accelerate progress in the endocrinology and neuroendocrinology fields. Endocrine Disruptors, Brain, and Behavior focuses on if and how these chemicals, known as endocrine disrupting compounds (EDCs), affect the development and function of the brain and might be contributing to neural disorders rapidly rising in prevalence. The book provides an overall synthesis of the EDC field, including its historical roots, major hypotheses, key findings, and research gaps. The authors explain why even the concept of endocrine disruption is controversial in some circles, how differing definitions of endocrine disruption and what constitutes an "adverse" outcome on the brain shape public policy, and where the current capacity by different stakeholders (industry, academia, regulatory agencies) to evaluate chemicals for safety in a regulatory context begins and ends. The book concludes with suggestions for future research needs and a summary of emerging technology which might prove capable of more effectively evaluating existing and emerging chemicals for endocrine disrupting properties. As such, it provides the context for interdisciplinary and innovative input from a broad spectrum of fields, including those well-schooled in neuroscience, evolutionary biology, brain, behavior, sex differences, and neuroendocrinology.

Book excerpt: "A book about the influence of estrogens on memory would have been unthinkable as recently as 30 years ago. Although a few small studies in the late 1970's reported a beneficial effect of estrogens on memory in human women (Hackman and Galbraith, 1976; Fedor-Freybergh, 1977), examination of the role of estrogens in memory did not truly capture more widespread attention until the pioneering work of Barbara Sherwin and colleagues in 1988 and beyond. In her initial paper, Sherwin showed that bilateral removal of the ovaries (aka surgical menopause) led to impaired short-term and long-term memory, whereas treatment of surgically menopausal women with estradiol alone, testosterone alone, or estradiol plus testosterone prevented this decline (Sherwin, 1988). As a search for the terms "estrogen" and "memory" in PubMed illustrates, well over 2000 papers have been published on the subject of estrogens and memory in the ensuing decades. The vast majority of these studies have focused on the hippocampus, a bilateral medial temporal lobe structure essential for the formation of episodic memories, particularly those with spatial, contextual, relational, temporal, and recognition components (Olton et al., 1979; Morris et al., 1982; Kim and Fanselow, 1992; Squire, 1992; Cohen and Stackman, 2015; Tonegawa et al., 2015; Eichenbaum, 2017). Although various forms of learning and memory are mediated by numerous brain regions, including the prefrontal cortex, medial temporal lobe cortices, amygdala, striatum, and cerebellum, the hippocampus has received the lion's share of attention due to its central importance for episodic memory formation. Hippocampal damage produces profound retrograde amnesia for facts and events, as well as anterograde amnesia for new information and impairments in spatial navigation (Winocur, 1990; Anagnostaras et al., 2001; Clark et al., 2002; Gilboa et al., 2006). Hippocampal dysfunction in middle-aged and aged subjects is a primary contributor to age-related memory decline (Golumb et al., 1996; Grady et al., 2003; Apostolova et al., 2010; Burke and Barnes, 2010; Small et al., 2011; Yassa et al., 2011), and has also been implicated in the cognitive impairments observed in diseases such as schizophrenia and depression (Small et al., 2011; Nakahara et al., 2018; Santos et al., 2018; Ott et al., 2019). Moreover, the hippocampi of patients with Alzheimer's disease are substantially atrophied and burdened with copious amounts of amyloid plaques and neurofibrillary tangles, the hallmark pathologies of this insidious disease (Hyman et al., 1984; Walsh and Selkoe, 2004; Selkoe and Hardy, 2016). As such, understanding how estrogens influence hippocampal functioning may provide important insights not only about the fundamental neurobiology of memory processes, but also into the etiology of neuropsychiatric and neurodegenerative diseases"--

Available in PDF, EPUB and Kindle. Book excerpt: Stress: Neuroendocrinology and Neurobiology: Handbook of Stress Series, Volume 2, focuses on neuroendocrinology, the discipline that deals with the way that the brain controls hormonal secretion, and in turn, the way that hormones control the brain. There have been significant advances in our understanding of neuroendocrine molecular and epigenetic mechanisms, especially in the way in which stress-induced hormonal and neurochemical changes affect brain plasticity, neuronal connectivity, and synaptic function. The book features the topic of epigenetics, and how it enables stress and other external factors to affect genetic transmission and expression without changes in DNA sequence. Integrated closely with new behavioral findings and relevance to human disorders, the concepts and data in this volume offer the reader cutting-edge information on the neuroendocrinology of stress. Volume 2 is of prime interest to neuroscientists, clinicians, researchers, academics, and graduate students in neuroendocrinology, neuroscience, biomedicine, endocrinology, psychology, psychiatry, and in some areas of the social sciences, including stress and its management in the workplace. - Includes chapters that offer impressive scope with topics addressing the neuroendocrinology and endocrinology of stress - Presents articles carefully selected by eminent stress researchers and prepared by contributors that represent outstanding scholarship in the field - Richly illustrated, with explanatory figures and tables

Available in PDF, EPUB and Kindle. Book excerpt: Current Therapy in Medicine of Australian Mammals provides an update on Australian mammal medicine. Although much of the companion volume, Medicine of Australian Mammals, is still relevant and current, there have been significant advances in Australian mammal medicine and surgery since its publication in 2008. The two texts together remain the most comprehensive source of information available in this field. This volume is divided into two sections. The first includes comprehensive chapters on general topics and topics relevant to multiple taxa. Several new topics are presented including: wildlife health in Australia and the important role veterinarians play in Australia’s biosecurity systems; medical aspects of native mammal reintroductions and translocations; disease risk analysis; wildlife rehabilitation practices in Australia with an emphasis on welfare of animals undergoing rehabilitation; management of overabundant populations; immunology; and stress physiology. The second section provides updates on current knowledge relevant to specific taxa. Several appendices provide useful reference data and information on clinical reference ranges, recommended venipuncture sites, chemical restraint agent doses and regimens, a drug formulary and dental charts. Written by Australian experts, Current Therapy in Medicine of Australian Mammals is clinically oriented, with emphasis on practical content with easy-to-use reference material. It is a must-have for veterinarians, students, biologists, zoologists and wildlife carers and other wildlife professionals. This volume also complements, updates and utilises the resources of other books such as Radiology of Australian Mammals (Vogelnest and Allan 2015), Pathology of Australian Native Wildlife (Ladds 2009), Haematology of Australian Mammals (Clark 2004) and Australian Mammals: Biology and Captive Management (Jackson 2003), all CSIRO Publishing publications.

Available in PDF, EPUB and Kindle. Book excerpt: Feathers are amazing structures unique to birds and, for a variety of reasons, they need to be renewed periodically as a whole in a process called moult. During this process, all of the functions of plumage are impaired and most aspects of a bird's life are affected. Every moult determines a bird's appearance anew, and restores plumage efficacy for flight and insulation. Moult profoundly affects physiology and the organization of the annual cycle, and it constrains reproduction and migration. Given these major impacts, which are equal to the other annual challenges of reproduction and migration, it is surprising that research on moult has largely been so neglected a subject. Lukas Jenni and Raffael Winkler have brought together the widely scattered results of studies on the processes and consequences of moult in birds. This book opens with an overview of the functions of plumage, and of feather maintenance and feather wear, and then introduces the two functions of moult: replacement of worn feathers and adjustment of plumage characteristics and appearance. The body of the book then examines feather-growth and the physiology, energetics and control of moult, and how various other physiological processes interact with moult and may compensate for its costs. Significantly, the authors explain how variations in moult and feather quality affect a bird's overall plumage quality, and they highlight the resulting consequences in terms of physical performance, appearance and signalling. Finally, there is a review of all the various solutions that birds have developed to fit moult into the annual cycle. This long-awaited book covers for the first time all aspects of the biology of moult and fills an important gap in the literature, completing our understanding of how the most important annual events in a bird's life fit together into a coherent whole. It draws on a wide range of information – from penguins to small passerines, from raptors to wildfowl – to highlight the variety of the subject and to pinpoint the many gaps in our knowledge along with avenues for fruitful further research.

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.

Available in PDF, EPUB and Kindle. Book excerpt: In this fascinating book, Jacques Balthazart presents a simple description of the biological mechanisms that are involved in the determination of sexual orientation in animals and also presumably in humans. Using scientific studies published over the last few decades, he argues that sexual orientation, both homosexual and heterosexual, is under the control of embryonic endocrine and genetic phenomena in which there is little room for individual choice. The author begins with animal studies of the hormonal and neural mechanisms that control the so-called instinctive behaviors and analyzes how this animal work may potentially apply to humans. The book does not focus exclusively on homosexuality, however. Instead, the book acts as a broader guide to the biological basis of sexual orientation, and also discusses important gender differences that may influence sexual orientation. While firmly grounded in the scientific literature, this text is developed for a broader audience and will be of interest to psychologists, researchers, students, and anyone interested in the biological factors that determine our sexuality.
