Book Description
Small Carnivores: Evolution, Ecology, Behaviour, and Conservation This book focuses on the 232 species of the mammalian Order Carnivora with an average body mass 21.5 kg. Small carnivores inhabit virtually all of the Earth's ecosystems, adopting terrestrial, semi-fossorial, (semi-)arboreal or (semi-)aquatic lifestyles. They occupy multiple trophic levels and therefore play important roles in the regulation of ecosystems, such as natural pest control, seed dispersal and nutrient cycling. In areas where humans have extirpated large carnivores, small carnivores may become the dominant predators, which may increase their abundance ("mesopredator release") to the point that they can sometimes destabilize communities, drive local extirpations and reduce overall biodiversity. On the other hand, one third of the world's small carnivores are threatened or near threatened with extinction. This results from regionally burgeoning human populations' industrial and agricultural activities, causing habitat reduction, destruction, fragmentation and pollution. Overexploitation, persecution and the impacts of introduced predators, competitors, and pathogens have also negatively affected many small carnivore species. Although small carnivores have been intensively studied over the past decades, bibliometric studies showed that they have not received the same attention given to large carnivores. Furthermore, there is huge disparity in how research efforts on small carnivores have been distributed, with some species intensively studied and others superficially or not at all. This book aims at filling a gap in the scientific literature by elucidating the important roles of, and documenting the latest knowledge on, the world's small carnivores. p"This is a book that has been needed for decades. It is the first compendium of recent research on a group of mammals which has received almost no attention before the early 1970s. This book covers a wide range of subdisciplines and techniques and should be considered a solid baseline for further research on this little-known group of highly interesting mammals. As our knowledge regarding how ecosystems function increases, then the valuable role of small carnivores and the necessity for their conservation should be regarded as of paramount importance. The topics covered in this book should therefore be of great interest not only to academics and wildlife researchers, but also to the interested layman."

Book Description
The Australian continent provides a unique perspective on the evolution and ecology of carnivorous animals. In earlier ages, Australia provided the arena for a spectacular radiation of marsupial and reptilian predators. The causes of their extinctions are still the subject of debate. Since European settlement, Australia has seen the extinction of one large marsupial predator (the thylacine), another (the Tasmanian devil) is in danger of imminent extinction, and still others have suffered dramatic declines. By contrast, two recently-introduced predators, the fox and cat, have been spectacularly successful, with devastating impacts on the Australian fauna. Carnivores of Australia: Past, Present and Future explores Australia's unique predator communities from pre-historic, historic and current perspectives. It covers mammalian, reptilian and avian carnivores, both native and introduced to Australia. It also examines the debate surrounding how best to manage predators to protect livestock and native biodiversity. Readers will benefit from the most up-to-date synthesis by leading researchers and managers in the field of carnivore biology. By emphasising Australian carnivores as exemplars of flesh-eaters in other parts of the world, this book will be an important reference for researchers, wildlife managers and students worldwide.

Book Description
“Where were you when I laid the foundation of the earth?” God asks Job in the “Whirlwind Speech,” but Job cannot reply. This passage—which some environmentalists and religious scholars treat as a “green” creation myth—drives H. H. Shugart’s extraordinary investigation, in which he uses verses from God’s speech to Job to explore the planetary system, animal domestication, sea-level rise, evolution, biodiversity, weather phenomena, and climate change. Shugart calls attention to the rich resonance between the Earth’s natural history and the workings of religious feeling, the wisdom of Bible scripture, and the arguments of Bible ethicists. The divine questions that frame his study are quintessentially religious, and the global changes humans have wrought on the Earth operate in not only the physical, chemical, and biological spheres but also the spiritual realm. Shugart offers a universal framework for recognizing and confronting the global challenges humans now face: the relationship between human technology and large-scale environmental degradation; the effect of invasive species on the integrity of ecosystems; the role of humans in generating wide biotic extinctions; and the future functioning of our oceans and tides.

Book Description
Environmental conditions change considerably in the course of 24 h with respect to abiotic factors and intra- and interspecific interactions. These changes result in limited time windows of opportunity for animal activities and, hence, the question of when to do what is subject to fitness maximisation. This volume gives a current overview of theoretical considerations and empirical findings of activity patterns in small mammals, a group in which the energetic and ecological constraints are particularly severe and the diversity of activity patterns is particularly high. Following a comparative ecological approach, for the first time activity timing is consequently treated in terms of behavioural and evolutionary ecology, providing the conceptual framework for chronoecology as a new subdiscipline within behavioural ecology. An extensive Appendix gives an introduction to methods of activity modelling and to tools for statistical pattern analysis.

Book Description
The Emeryville Shellmound, on the east shore of San Francisco Bay, was excavated and subsequently destroyed in the early twentieth century. From its stratified deposits, which span the period 2600 to 700 years ago, the author identified 2,004 fish and 15,893 mammal specimens, and analyzed these and 2,302 avian remains previously identified by Hildegarde Howard in the 1920s. A battery of independent tests derived from foraging theory supports the conclusion that human-induced impacts on vertebrate populations caused declines in the efficiency of foraging across the time that the Emeryville locality was occupied.
