Mechanisms of seasonal phenotypic flexibility of metabolism in small birds. Small birds wintering in cold climates generally show substantial improvements in cold hardiness in winter relative to summer and this improvement in cold hardiness is largely metabolic in nature. Another major focus of my laboratory is to examine the mechanistic basis of these seasonal improvements in cold hardiness. We take an integrative approach to addressing these mechanistic questions by looking at seasonal changes occurring over multiple levels of organization. Examples include thermogenic capacity and basal metabolic rate at the organismal level; mass changes in organs and tissues; and mobilization, transport and catabolic capacities for metabolic substrates in storage tissues, plasma and muscle cells. By studying winter acclimatization at these various levels we hope to discern both fundamental and variable responses promoting cold adjustment in small birds.
