Over the past two decades, comparative biological analyses have undergone profound
changes with the incorporation of rigorous evolutionary perspectives and phylogenetic …

Life‐history traits in birds, such as lifespan, age at maturity, and rate of reproduction, vary
across environments and in combinations imposed by trade‐offs and limitations of …

Aim Physiology is emerging as a basis for understanding the distribution and diversity of
organisms, and ultimately for predicting their responses to climate change. Here we review …

This book offers a concise but comprehensive introduction to desert ecology and adopts a
strong evolutionary focus. As with other titles in the Biology of Habitats Series, the emphasis …

The basal rate of metabolism (BMR) in 533 species of birds, when examined with ANCOVA,
principally correlates with body mass, most of the residual variation correlating with food …

Diversifying selection on metabolic pathways can reduce intraspecific gene flow and
promote population divergence. An opportunity to explore this arises from mitonuclear …

Metabolic rate is a key aspect of organismal biology and the identification of selective factors
that have led to species differences is a major goal of evolutionary physiology. We tested …

Energy expenditure in animals scales allometrically with body mass, but residual variation is
not well understood. We examine the existing data on field metabolic rates (FMR) in …

As ecosystems undergo global changes, there is increasing interest in understanding how
organisms respond to changing environments. Recent evidence drawn from available …

Physiological performance declines precipitously at high body temperature (T b), but little
attention has been paid to adaptive variation in upper T b limits among endotherms. We …
