"A synthetic account of the diversity and ecology of wild parrots, distilling knowledge from the author's own research and from her review of more than 2,400 published scientific studies. The text covers parrots' evolutionary history, foraging, mating, and social behavior, innate intelligence, and conservation status. The book is enhanced by an array of illustrations, including photos of parrots taken exclusively in their natural habitat"--Provided by publisher.
Parasitic relationships are among the most common yet complex associations found in nature. This book makes an important contribution toward integrating parasitology into the mainstream of ecological and evolutionary studies. It delves into a number of key questions: to what extent are parasite-host interactions an escalating evolutionary conflict and, conversely, to what extent has evolution modified this process to facilitate co-existence? The first section of the book deals with whole organisms and populations, since the effects of parasitism are dependent on the densities and distributions of hosts and parasites. The next section considers special cases, such as herbivores and plants. The third part is devoted to physiological and immunological aspects, and the book concludes with an overview from the perspectives of ecology, evolution, and physiology. The work will interest ecologists, evolutionary biologists, parasitologists, entomologists, and epidemiologists.
Cockatoos are large, intelligent and attractive birds. Of the twenty-one recognized species, fourteen occur in Australia, with three of these also found in New Guinea. Seven species are distributed across the islands of south-east Asia. While many species are common or abundant, an increasing number face extinction due to habitat loss, the illegal bird trade and global warming.
