​This volume provides comprehensive overviews of the biology of each European carnivoran species, 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 Carnivora and will appeal to academics, students and professionals in mammal research.

The fundamental concept of The Biology and Identification of the Coccidia (Apicomplexa) of Carnivores of the World is to provide an up-to-date reference guide to the identification, taxonomy, and known biology of apicomplexan intestinal and tissue parasites of carnivores including, but not limited to, geographic distribution, prevalence, sporulation, prepatent and patent periods, site(s) of infection in the definitive and (if known) intermediate hosts, endogenous development, cross-transmission, pathology, phylogeny, and (if known) their treatments. These data will allow easy parasite recognition with a summation of virtually everything now known about the biology of each parasite species covered. The last (very modest) and only treatise published on this subject was in 1981 so this book fills a fundamental gap in our knowledge of what is now known, and what is not, about the coccidian parasites that infect and sometimes kill carnivores and/or their prey that can harbor intermediate stages, including many domestic and game animals.

Offers line drawings and photomicrographs of many parasite species that will allow easy diagnosis and identification by both laypersons and professionals (veterinarians, wildlife biologists, etc.) Presents a complete historical rendition of all known publications on carnivore coccidia for all carnivore families and evaluates the scientific and scholarly merit of each apicomplexan species relative to the current body of knowledge Provides a complete species analysis and their known biology of all coccidia described from each carnivore lineage and species Reviews the most current taxonomy of carnivores and their phylogenetic relationships to help assess host-specificity patterns that may be apparent Evaluates what little cross-transmission work is available to help understand the complexities of those coccidians that use two hosts (e.g., Sarcocystis, Besnoitia, and others) Provides known treatments for the various parasite genera/species

The Atlantic Walrus: Multidisciplinary insights into human-animal interactions addresses the key dimensions of long-term human walrus interactions across the Atlantic Arctic and subarctic regions, over the past millennia. This book brings together research from across the social and natural sciences to explore walrus biology, human culture, environmental conditions and their reciprocal effects. Together, 13 chapters of this book reconstruct the early evolution of walruses, walrus biology, the cultural significance and ecological impact of prehistoric and indigenous hunting practices, as well as the effects of commercial hunting and international trade. This book also examines historic and ongoing management strategies and, the importance of new research methodologies in revealing hitherto unknown details of the past, and concludes by discussing the future for Atlantic walruses in the face of climate change and increased human activities in the Arctic.

This volume is an ideal resource for those who are seeking to understand an iconic Arctic species and its long and complex relationship with humans. This includes individuals and researchers with a personal or professional connection to walruses or the Arctic, as well as marine biologists, zoologists, conservationists, paleontologists, archaeologists, anthropologists, historians, indigenous communities, natural resource managers and government agencies.

Provides succinct overviews of the biology of the Atlantic Walrus (Odobenus rosmarus rosmarus) as well as human cultures within the North Atlantic Arctic and the surrounding region by consolidating research which until now has been scattered across fields and academic publications Editorial team of inter-disciplinary researchers ensuring the breadth, depth and integration of material covered throughout the volume Thirteen chapters, each authored by leading international researchers and experts on the Atlantic Walrus Considers the inter-relatedness and complexity of species biology, ecological change, human culture, and anthropogenic pressures onto the Atlantic Walrus, all while remaining accessible to readers from different disciplines or a more generalist audience Draws upon the latest methods in marine mammal and archaeological research Assesses historical management of the species, while also considering current and future conservation efforts in light of human activities and climate change Text supported by striking and insightful new maps and scientific illustrations, ideal for teaching and outreach

The new edition of the Field Guide to Illinois Mammals is a pocket-sized handbook on the state's sixty-one species. Joyce Hofmann provides entries with extensive physical descriptions, and information on lookalike species, behaviors, habitats, tracks and scat, and population status, and range. More than 200 color photos, drawings, and illustrations aid at-a-glance identification while distribution maps show where each species is known to occur in the state.Designed to use in the field or the backyard, Field Guide to Illinois Mammals updates a singular reference for wildlife biologists, ecologists, hikers, armchair adventurers, and anyone else fascinated by the state's wildlife.

A growing body of evidence has begun to reveal flaws in the traditional assumption of female passivity and lack of discrimination after copulation has begun. William Eberhard has compiled an impressive array of research on the ability of females to shape the outcome of mating. He describes studies of many different cryptic mechanisms by which a female can accept a male for copulation but nevertheless reject him as a father. Evidence from various fields indicates that such selectivity by females may be the norm rather than the exception. Because most post-copulatory competition between males for paternity is played out within the bodies of females, female behavior, morphology, and physiology probably often influence male success in these contests. Eberhard draws examples from a diversity of organisms, ranging from ctenophores to scorpions, nematodes to frogs, and crickets to humans. Cryptic female choice establishes a new bridge between sexual selection theory and reproductive physiology, in particular the physiological effects of male seminal products on female reproductive processes, such as sperm transport, oviposition, and remating.Eberhard interweaves his review of previous studies with speculation on the consequences of this theoretical development, and indicates promising new directions for future research.

With only 5,000 surviving, the African wild dog (Lycaon pictus) is one of the world's most endangered large carnivores--and one of the most remarkable. This comprehensive portrait of wild dogs incorporates previously scattered information with important new findings from a six-year study in Tanzania's Selous Game Reserve, Africa's largest protected area. The book emphasizes ecology, concentrating on why wild dogs fare poorly in protected areas that maintain healthy populations of lions, hyenas, or other top carnivores. In addition to conservation issues, it covers fascinating aspects of wild dog behavior and social evolution. The Creels use demographic, behavioral, endocrine, and genetic approaches to examine how and why nonbreeding pack mates help breeding pairs raise their litters. They also present the largest data set ever collected on mammalian predator-prey interactions and the evolution of cooperative hunting, allowing them to account for wild dogs' prowess as hunters. By using a large sample size and sophisticated analytical tools, the authors step well beyond previous research.Their results include some surprises that will cause even specialists to rethink certain propositions, such as the idea that wild dogs are unusually vulnerable to infectious disease. Several findings apply broadly to the management of other protected areas. Of clear appeal to ecologists studying predation and cooperation in any population, this book collects and expands a cache of information useful to anyone studying conservation as well as to amateurs intrigued by the once-maligned but extraordinary wild dog.
