Snakes, Sunrises, and Shakespeare: How Evolution Shapes Our Loves and Fears

Snakes, Sunrises, and Shakespeare: How Evolution Shapes Our Loves and Fears Description:

Our breath catches and we jump in fear at the sight of a snake We pause and marvel at the sublime beauty of a sunrise These reactions are no accident in fact many of our human responses to nature are steeped in our deep evolutionary past we fear snakes because of the danger of venom or constriction and we welcome the assurances of the sunrise as the predatory dangers of the dark night disappear Many of our aesthetic preferences from the kinds of gardens we build to the foods we enjoy and the entertainment we seek are the lingering result of natural selection br br In this ambitious and unusual work evolutionary biologist Gordon H Orians explores the role of evolution in human responses to the environment beginning with why we have emotions and ending with evolutionary approaches to aesthetics Orians reveals how our emotional lives today are shaped by decisions our ancestors made centuries ago on African savannas as they selected places to live sought food and safety and socialized in small hunter gatherer groups During this time our likes and dislikes became wired in our brains as the appropriate responses to the environment meant the difference between survival or death His rich analysis explains why we mimic the tropical savannas of our ancestors in our parks and gardens why we are simultaneously attracted to danger and approach it cautiously and how paying close attention to nature s sounds has resulted in us being an unusually musical species We also learn why we have developed discriminating palates for wine and why we have strong reactions to some odors and why we enjoy classifying almost everything br br By applying biological perspectives ranging from Darwin to current neuroscience to analyses of our aesthetic preferences for landscapes sounds smells plants and animals i Snakes Sunrises and Shakespeare i transforms how we view our experience of the natural world and how we relate to each other

Biodiversity And Ecosystem Processes In Tropical Forests

Biodiversity And Ecosystem Processes In Tropical Forests Description:

Although biologists have directed much attention to estimating the extent and causes of species losses the consequences for ecosystem functioning have been little studied br This book examines the impact of biodiversity on ecosystem processes in tropical forests one of the most species rich and at the same time most endangered ecosystems on earth It covers the relationships between biodiversity and primary production secondary production biogeochemical cycles soil processes plant life forms responses to disturbance and resistance to invasion The analyses focus on the key ecological interfaces where the loss of keystone species is most likely to influence the rate and stability of ecosystem processes

Some Adaptations of Marsh-Nesting Blackbirds. (Mpb-14)

Some Adaptations of Marsh-Nesting Blackbirds. (Mpb-14) Description:

br The variety of social systems among the New World blackbirds Family Icteridae and the structural simplicity of their foraging environment provide excellent opportunities for testing theorics about the adaptive significance of their behavior Here Gordon Orians presents the results of his many years of research on how blackbirds utilize their marsh environments during the breeding season These results stem from information he gathered on three species during ten breeding seasons in the Pacific Northwest on Red winged blackbirds during two breeding seasons in Costa Rica and on three species during one breeding season in Argentina br The author uses models derived from Darwin s theory of natural selection to predict the behavior and morphology of individuals as well as the statistical properties of their populations First he tests models that predict habitat selection foraging behavior territoriality and mate selection Then he considers some population patterns especially range of use of environmental resources and overlap among species that may result from those individual attributes Professor Orianns concludes with an overview of the structure of bird communities in marshes of the world and the relation of these patterns to overall source availability in these simple but productive habitats br

The Preservation and Valuation of Biological Resources

The Preservation and Valuation of Biological Resources Description:

Human activities are threatening the extinction of a substantial number of species living on earth The immense scale of the impending extinction crisis means that hard choices must be made about what to conserve with limited resources How can we estimate the value of species in natural ecosystems their value in terms of the products and services they provide and their role in enhancing the quality of human life Answers to these questions are necessary for the development of wise policies concerning the allocation of societal resources for the preservation and management of the planet s living resources br br In this book a distiguished group of biologists economists and resource managers presents a mutlidisciplinary approach to the importance of the earth s biological richness The six major chapters focus on methods of preserving genetic resources both in the laboratory and in the field the biological value of species richness both genetic and ecological management of biological resources and economic methods of assessing the value of species The essays are accompanied by commentaries and summaries written by specialists from a variety of disciplines A final chapter provides an overview culminating in suggestions for needed research
