"This volume summarizes new developments in understanding the longest-lived icehouse period in Phanerozoic Earth history, the late Paleozoic ice age. Resolving the Late Paleozoic Ice Age in Time and Space provides summaries of existing and new data from the various Gondwanan continental relics, and also reviews stratigraphic successions from the paleotropical and temperate regions of Laurussia that preserve an indirect record of glaciation. It addresses the extent to which records of glaciation indicate protracted, long-term climatic austerity, as opposed to fluctuating, more dynamic climate, and provides new constraints on the timing of glaciation. Additionally, it tackles questions of synchroneity of glaciation across the various Gondwanan continental relics, and timing relationships between near-field and far-field records at greater levels of resolution than has been possible previously. Results point toward a dynamic icehouse regime that is comparable to the Cenozoic icehouse, and away from traditional interpretations of the late Paleozoic ice age as a single, protracted event that involved stable, long-lived ice centers."--Publisher's website.
Sturkie's Avian Physiology, Seventh Edition is the classic comprehensive single volume on the physiology of domestic as well as wild birds. This latest edition is thoroughly revised and updated and features several new chapters with entirely new content on such topics as vision, sensory taste, pain reception, evolution, and domestication. Chapters throughout have been greatly expanded due to the many recent advances in the field. This book is written by international experts in different aspects of avian physiology. For easy reading and searches, this book is structured under a series of themes, beginning with genomic studies, sensory biology and nervous systems, and major organs. The chapters then move on to investigate metabolism, endocrine physiology, reproduction, and finally cross-cutting themes such as stress and rhythms. New chapters on feathers and skin are featured as well. Sturkie's Avian Physiology, Seventh Edition is an important resource for ornithologists, poultry scientists, and other researchers in avian studies. It is also useful for students in avian or poultry physiology, as well as avian veterinarians. - Stands out as the only single volume devoted to bird physiology - Features updates, revisions, or additions to each chapter - Written and edited by international leaders in avian studies
"After drawing its first breath every newborn mammal turns his or her complete attention to obtaining milk. This simple act was once thought to stem from a basic fact - milk provides the initial source of calories and nutrients for all mammalian young. That truth, however, is only a piece of the story. Milk, it turns out, is an extremely complex biochemical cocktail. The authors of this fascinating book, biologists Michael L. Power and Jay Schulkin, reveal milk's ancient history and show how the ingredients of mother's milk have evolved over many mammalian generations. Power and Schulkin walk us through the evolutionary origins of the mammary gland and describe the incredible diversification of milk among the various mammalian lineages, culminating in a discussion of the history of humans and milk. Once the roots of lactation are revealed, the authors describe the long list of substances that naturally occur in milk. They discuss all of the biological functions of milk - functions that reach far beyond being a baby's first food. Mothers, it turn out, pass along numerous biochemical signals to their babies through milk. The authors describe how milk boosts an infant's immune system, affects an infant's metabolism and physiology, and even helps inoculate and feed the baby's gut microbiome. Throughout the book the authors weave in stories from studies of other species, explaining how comparative research sheds light on human lactation. The authors then turn their attention to the fascinating topic of cross-species milk consumption"--
