WIKELSKI, Martin C; Princeton University: Migration ecology of New World Thrushes: energetics and orientation in the wild George A. Bartholomew pioneered the investigation of physiological mechanisms in natural settings and sparked an amazing diversity of research directions. However, the migration physiology of free-flying songbirds is still largely unknown because adequate methodology to study it was […]

WAINWRIGHT, P.C.; Univ. of California, Davis: Making diversity: the evolution of feeding mechanics in fishes Biological diversity is not only about the number of taxa on earth, but also their morphological and functional diversity. My research program is aimed at understanding how functional diversity arises through studies of the feeding mechanism of fishes. We have […]

HUEY, R.B.*; HOFMANN, G.E.; Univ. of Washington, Seattle; Univ. of California, Santa Barbara: Introduction to the Bartholomew Award and Symposium We describe the rationale and history of the G. A. Bartholomew Award, and introduct the Symposium.

BLOCK, BA; Stanford University: Hot Tuna in Cold Seas: The Ecological Physiology and Conservation of Giant Bluefin Tuna have historically been a challenge to study due to their size, speed and range over the vast oceanic habitat. Electronic tagging and remote sensing technologies are revolutionizing the study of tunas in the open ocean. Critical information […]

DAWSON, W.R.; Univ. of Michigan, Ann Arbor: George A. Bartholomew’s contributions to integrative and comparative biology The Bartholomew Award has now completed a decade of recognizing outstanding young investigators in comparative physiology and biochemistry or in related fields of functional and integrative biology. It honors Professor George A. Bartholomew (�Bart� to his many students and […]

SUMMERS, A.P.; Univ. Of California, Irvine: Felling trees with a sock full of custard ? the evolution of durophagy in cartilaginous fishes Chimaeras, sharks and rays abandoned a bony skeleton in favor of one of mineralized and unmineralized cartilage. Though reports on the material properties of shark cartilage are rare it is clear that mammalian […]

SECOR, S.M; University of Alabama, Tuscaloosa: Evolutionary and proximate mechanisms of intestinal adaptation Vertebrates display a broad spectrum of adaptive responses of their digestive system to feeding and fasting. This is exemplified among amphibians and reptiles from species that feed relatively frequently and experience modest fluctuations in intestinal performance to those species that feed infrequently […]

HAYES, Tyrone B.; Univ. of California, Berkeley: Evolutionary Developmental Endocrinology: Evolution of Mechanisms and Mechanisms of Evolution As in all vertebrates, hormones are critical in amphibian growth and development. Thyroid hormones regulate larval development and metamorphosis and have a permissive role in sexual development, glucocorticoids modulate thyroid hormone activity and effect immune function and somatic […]
