Bird Hormones And Bird Migrations: Analyzing Hormones in Droppings And Egg-yolks And Assessing Adaptations in the Long-distance Migration
de et al.(Ed. New York Academy of Sciences) Isbn : 1573315761
123.5 €
The analysis of hormones in feces or excrement presented in the first part of this volume is a relatively new noninvasive method for gaining insight into an animal′s physiology. Endocrinological cycles of free–living animals can be studied without the stress caused by capture. Hence, this noninvasive technique may be helpful in a wide range of research fields relating to physiology, behavioral ecology, ethnology, and wildlife conservation. The reports presented in the second part of the volume expand the general understanding of migration over long distances. Three key issues in the search for adaptive syndromes are addressed: acquisition and use of endogenous resources, circadian rhythms, and adaptations in metabolism. The papers included in this volume will provide access t...

The Adelie Penguin: Bellwether of Climate Change
de David G. Ainley(Ed. Columbia Univ Pr) Isbn : 0231123078
Prix : NC
The Adélie penguin is one of the best-studied birds in the world and is the subject of research programs from a dozen nations interested in monitoring changes in the environment and the food webs of the Southern Ocean. This species´ population has been changing dramatically over the past few decades coincident with a general warming of the maritime portion of Antarctica. When the sea-ice is seen to decline so does the population of Adélie penguins. Further south, however, the population is increasing. This book summarizes our present ecological knowledge of this polar seabird. In so doing, David Ainley describes the ecological factors important to its life history and details the mechanisms by which it is responding to climate change. The author also chronicles the history of research on A...
