This book provides a comprehensive survey of the diversity and biology of metazoan parasites affecting small mammals, of their impact on host individuals and populations, and of the management implications of these parasites for conservation biology and human welfare. Designed for a broad, multidisciplinary audience, the book is an essential resource for researchers, students, and practitioners alike.
Compiles and interprets information on the diversity, distribution, and adaptations of parasitic arthropods that provides the basis for studies on the evolution of biological relationships between parasites and hosts. Focuses on obligate, permanent parasites of the Insecta and Acari--including Anoplura, Mallophaga, Siphonaptera and miscellaneous parasitic insects, mites, and ticks. Coevolutionary theories are reviewed and new models are presented for the evolution of parasitic arthropods and mammals.
Many mites possess extremely intricate life styles in close association with plant and animal hosts. Their polymorphism has made classification a challenge, and their ability to reproduce both sexually and asexually has made efforts to control their populations difficult. This, however, has given rise to theories to explain the origin and function of sexual reproduction in general. In numbers of species and geographic distribution, mites may even surpass the insects. In soils, they are a major component in the system for cycling nutrients. Unlike insects, they have invaded the marine environment. These and a number of other topics are explored in Mites. Because of their extremely small size, mites have been ignored during the development of major evolutionary and ecological theories. Yet mites routinely violate fundamental concepts such as heterochrony, sexual selection, the evolution of sex ratio, and ontogeny. Recent research methodologies have made it practical for the first time to perform experimental work with mites, and since they offer short generation times and rapid research results, they are excellent model systems. Mites announces these results and should appeal to professionals in entomology, acarology, ecology, population genetics, and evolutionary biology.
Bats are highly gregarious mammals that have been extensively studied for their ability to echolocate (i.e., gain information from the echoes of ultrasonic calls) to navigate and find food. Perhaps less well studied are social vocalizations, which bats use to communicate with conspecifics. Some bat species have been shown to possess rich vocal repertoires, supporting intricate social interactions. While the roost is likely where the majority of a bat's social interactions occur, on account of higher densities, there are also behavioral contexts that occur predominantly, if not solely in flight, that are associated with social calls. Bats exhibit an extensive range in social group size, social group organization, and mating systems, making them interesting for comparative, phylogenetically controlled analyses. Group size is often correlated with vocal complexity, as more complex vocalizations can encode more information about individual identity. Vocal learning has been observed in some species of bats. The full vocal repertoires of relatively few bat species have been studied thus far, as they are nocturnal, volant animals that produce predominately ultrasonic vocalizations. With more data available, bats would be a very useful taxon for studying the evolution of social communication, as they exhibit not only a high diversity of social group size and complexity but also sophisticated vocalizations. Social vocalizations can be structurally diverse and are highly important for bat sociality. Calls often vary notably between species. Research in this field has barely scratched the surface, and there is still much to learn about social communication in bats.
PreliminaryThis volume provides comprehensive overviews of each European bat species’ biology including palaeontology, physiology, genetics, reproduction and development, ecology, habitat, diet, mortality and age determination. Their economic significance and management, as well as future challenges for research and conservation are also addressed. Each chapter includes a distribution map, a photograph of the animal and key literature. This authoritative volume of the Handbook of the Mammals of Europe is a timely and detailed compilation of all European bats and will appeal to academics, students and professionals in mammal research.
