Download or read book The Evolution of Primary Sexual Characters in Animals written by Janet Leonard and published by Oxford University Press. This book was released on 2010-07-16 with total page 550 pages. Available in PDF, EPUB and Kindle. Book excerpt: Primary sexual traits, those structures and processes directly involved in reproduction, are some of the most diverse, specialized, and bizarre in the animal kingdom. Moreover, reproductive traits are often species-specific, suggesting that they evolved very rapidly. This diversity, long the province of taxonomists, has recently attracted broader interest from evolutionary biologists, especially those interested in sexual selection and the evolution of reproductive strategies. Primary sexual characters were long assumed to be the product of natural selection, exclusively. A recent alternative suggests that sexual selection explains much of the diversity of "primary" sexual characters. A third approach to the evolution of reproductive interactions after copulation or insemination has been to consider the process one of sexual conflict. That is, the reproductive processes of a species may reflect, as does the mating system, evolution acting on males and on females, but in different directions. In this volume, authors explore a wide variety of primary sexual characters and selective pressures that have shaped them, from natural selection for offspring survival to species-isolating mechanisms, sperm competition, cryptic female choice and sexual arms races. Exploring diverse reproductive adaptations from a theoretical and practical perspective, The Evolution of Primary Sexual Characters will provide an unparalleled overview of sexual diversity in many taxa and an introduction to the issues in sexual selection that are changing our view of sexual processes.
Download or read book Ecology of small mammals written by D.M. Stoddart and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: From their largely descriptive beginnings about a half century ago, studies on the ecology of small mammals have mushroomed in number, scope, content and complexity. Yet strangely, or perhaps not so strangely if one considers the extent and complexity of ecological interactions, the main problems for which the early workers sought answers still defy complete analysis, and basic hypotheses remain untested if not even untestable. The same holds true for so many branches of animal ecology that it seems to be the complexity of the concepts that frustrates efforts rather than the subject species. Like all branches of science, small mammal ecology has been subject to a series of fashionable approaches, one following another as tech nology penetrates previously impregnable regions. Doubtless the future development of our science will be punctuated by wave upon wave of new endeavour in whole fields that are perhaps even yet unidentified. Answers to the complex questions which ecologists ask do not come easily. Increasingly though, they arise in direct proportion to the efforts expended upon their elucidation. Many studies have achieved such a high level of elegance, in terms of manpower and apparatus, that there is a feeling that questions asked when such resources are unavailable are not worth asking. Nothing could be further from the truth. Many a complex model has failed fully to explain the phenomenon for which it was construc ted because of a lack of basic field data on the species' natural h~story.

Download or read book Rotifera X written by Alois Herzig and published by Springer Science & Business Media. This book was released on 2006-02-27 with total page 578 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume reflects the latest developments in the research of a global community of rotifer researchers, who came together at Illmitz, Austria in 2003. Contributions are manifold and span fields from phylogeny and evolution of the phylum Rotifera to practical aspects of aquaculture and ecotoxicology. Major issues include phylogeny and evolution, genetics and molecular ecology, new aspects of rotifer anatomy through the application of confocal laser-scanning microscopy, anhydrobiosis, long-term studies in lakes and rivers, population dynamics and community ecology, trophic relationships between copepods and rotifers, alongside biodiversity studies based on classical taxonomic concepts and molecular approaches. Although primarily focussed on one taxonomic group, the scientific outcome of this meeting is of relevance to the study of other aquatic microinvertebrates as well.
Download or read book Thinking Like a Parrot written by Alan B. Bond and published by University of Chicago Press. This book was released on 2021-12-06 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: From two experts on wild parrot cognition, a close look at the intelligence, social behavior, and conservation of these widely threatened birds. People form enduring emotional bonds with other animal species, such as dogs, cats, and horses. For the most part, these are domesticated animals, with one notable exception: many people form close and supportive relationships with parrots, even though these amusing and curious birds remain thoroughly wild creatures. What enables this unique group of animals to form social bonds with people, and what does this mean for their survival? In Thinking like a Parrot, Alan B. Bond and Judy Diamond look beyond much of the standard work on captive parrots to the mischievous, inquisitive, and astonishingly vocal parrots of the wild. Focusing on the psychology and ecology of wild parrots, Bond and Diamond document their distinctive social behavior, sophisticated cognition, and extraordinary vocal abilities. Also included are short vignettes—field notes on the natural history and behavior of both rare and widely distributed species, from the neotropical crimson-fronted parakeet to New Zealand’s flightless, ground-dwelling kākāpō. This composite approach makes clear that the behavior of captive parrots is grounded in the birds’ wild ecology and evolution, revealing that parrots’ ability to bond with people is an evolutionary accident, a by-product of the intense sociality and flexible behavior that characterize their lives. Despite their adaptability and intelligence, however, nearly all large parrot species are rare, threatened, or endangered. To successfully manage and restore these wild populations, Bond and Diamond argue, we must develop a fuller understanding of their biology and the complex set of ecological and behavioral traits that has led to their vulnerability. Spanning the global distribution of parrot species, Thinking like a Parrot is rich with surprising insights into parrot intelligence, flexibility, and—even in the face of threats—resilience.

Download or read book A Checklist of Host Parasite Interactions of the Order Crocodylia written by Marisa Tellez and published by Univ of California Press. This book was released on 2014-05-15 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: Records of parasitism in crocodilians date back to the early 1800s, distributed among various types of published and unpublished materials. Analyzing parasite-host specificity, geographic distribution, and taxonomy can provide otherwise cryptic details about crocodilian ecology and evolution, as well as their local food web dynamics. This information is critical for improved conservation tactics for both crocodilians and their habitat. As climate change, anthropogenic conflict, and environmental pollution endanger crocodilian ecosystems, there is a need for organized information on crocodile, alligator, caiman, and gharial infectious diseases. This volume meets this need by delivering the first checklist of crocodilians and their parasites for researchers and scholars in biology, herpetology, and ecology in order to further the knowledge and study of crocodilian-parasite dynamics and improve our understanding of human impacts on ecosystems.

Available in PDF, EPUB and Kindle. Book excerpt: For many years the Keys have provided a working tool to those within the field and laboratory needing to know "what is this worm?" They have also helped to establish a classification, using associations of characters, that gives real insight into nematode relationships across the group and their lines of evolution. This supplementary volume is designed to complement the original CIH Keys, now reprinted as one volume, with the additional convenience of reordering into superfamily. The supplement includes revised and redescribed taxa and draws attention to new taxa, to generic level, published by many authors after the original Keys were complete. It also identifies the current position of some of the older genera not included in the original Keys.
