DOWNLOAD EBOOKPresenting a multidisciplinary perspective in a concise format, Principles of Ecotoxicology, Third Edition discusses the fundamental chemical and ecological nature of pollution processes while identifying the major classes of pollutants and their environmental fate. The first edition was originally created to fill the need for a textbook that covered the basic principles of a developing and wide-ranging field and the second edition expanded on that theme. Keeping the focus on principles over practice that has made each incarnation of this textbook so popular, the third edition brings the text up to date and strengthens coverage in areas that have come to the forefront of the field. The third edition features new material on pollutants that are receiving closer scrutiny, naturally occurring poisons, the history of chemical warfare, population risk assessment, community structure, neonicotinoids, endocrine disruption, and neurotoxicity. A new section on extrapolating from molecular interaction to the consequent population changes highlights the molecules to ecosystem approach and provides the groundwork for discussions on the employment of biomarker strategies in field studies. A major theme of the new material is how the concepts discussed can contribute to improved methods of environmental risk assessment. With updates to every chapter, this text provides essential information for students in easy to use and understandable format.

DOWNLOAD EBOOKNests, Eggs, and Incubation brings together a global team of leading authorities to provide a comprehensive overview of the fascinating and diverse field of avian reproduction. Starting with a new assessment of the evolution of avian reproductive biology in light of recent research, the book goes on to cover four broad areas: the nest, the egg, incubation, and the study of avian reproduction. New research on nest structures, egg traits, and life history is incorporated, whilst contemporary methodologies such as self-contained temperature probes and citizen science are also discussed. Applied chapters describe how biological knowledge can be applied to challenges such as urbanisation and climate change. The book concludes by suggesting priorities for future research. This book builds upon the foundations laid down by Charles Deeming's 2002 work Avian Incubation (available for readers of this book to access online for free), much of which remains relevant today. Read in conjunction with this previous volume, it provides an up-to-date and thorough review of egg biology, nest function, and incubation behaviour, which will be an essential resource for students of avian biology, as well as both professional and amateur ornithologists working in the field of avian reproduction.

DOWNLOAD EBOOKFrom the brilliantly green and glossy eggs of the Elegant Crested Tinamou—said to be among the most beautiful in the world—to the small brown eggs of the house sparrow that makes its nest in a lamppost and the uniformly brown or white chickens’ eggs found by the dozen in any corner grocery, birds’ eggs have inspired countless biologists, ecologists, and ornithologists, as well as artists, from John James Audubon to the contemporary photographer Rosamond Purcell. For scientists, these vibrant vessels are the source of an array of interesting topics, from the factors responsible for egg coloration to the curious practice of “brood parasitism,” in which the eggs of cuckoos mimic those of other bird species in order to be cunningly concealed among the clutches of unsuspecting foster parents. The Book of Eggs introduces readers to eggs from six hundred species—some endangered or extinct—from around the world and housed mostly at Chicago’s Field Museum of Natural History. Organized by habitat and taxonomy, the entries include newly commissioned photographs that reproduce each egg in full color and at actual size, as well as distribution maps and drawings and descriptions of the birds and their nests where the eggs are kept warm. Birds’ eggs are some of the most colorful and variable natural products in the wild, and each entry is also accompanied by a brief description that includes evolutionary explanations for the wide variety of colors and patterns, from camouflage designed to protect against predation, to thermoregulatory adaptations, to adjustments for the circumstances of a particular habitat or season. Throughout the book are fascinating facts to pique the curiosity of binocular-toting birdwatchers and budding amateurs alike. Female mallards, for instance, invest more energy to produce larger eggs when faced with the genetic windfall of an attractive mate. Some seabirds, like the cliff-dwelling guillemot, have adapted to produce long, pointed eggs, whose uneven weight distribution prevents them from rolling off rocky ledges into the sea. A visually stunning and scientifically engaging guide to six hundred of the most intriguing eggs, from the pea-sized progeny of the smallest of hummingbirds to the eggs of the largest living bird, the ostrich, which can weigh up to five pounds, The Book of Eggs offers readers a rare, up-close look at these remarkable forms of animal life.
