Bird Hormones and Bird Migrations
Analyzing Hormones in Droppings and Egg Yolks and Assessing Adaptations in Long-Distance Migration, Volume 1046
Annals of the New York Academy of Sciences
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 to
techniques and methods that will result in more reliable studies
and more useful data. The results of these two meetings are timely
and important because environments are rapidly changing and we need
the means to study the impact of these changes on the physiology of
animals who are responding to these changes.
