An organism's size is perhaps its most apparent characteristic. The recent outpouring of
studies on the influence of body size on all aspects of biology and evolution and the …

It is generally recognized that larger animals eat more, live longer, have larger offspring, and
so on; but it is unusual to see these commonplace observations as a basis for scientific …

B ody size is probably the single attribute of animal species most studied in the ecological
and evolutionary literatures, and with good reason. Most life history traits of an animal …

On average, large-bodied species live at lower densities than small-bodied ones. Early
studies suggested that population densities might scale so that the energy use of a …

An organism's size affects virtually all aspects of its physiology and ecology. There are
presently no theoretical models which can explain the broad patterns of shape and …

Age has traditionally been the categorical variable used in demographic models of
vertebrate populations (76, 87, 89, 132). This may be due in part to the historical …

The effort necessary to measure the differences in lifetime reproductive success in nature
has already been described convincingly (20). All impregnations, births, and deaths that …

On average, small-bodied organisms are more abundant than large ones (Elton 1927). This
relationship between individual body mass and population density (hereafter referred to as …

Allometric scaling, a widely used approach for studying the relationship between size,
shape, and function in organisms, is examined in both concept and application. Several …

Increase in the mean size of individuals during evolution is a widespread phenomenon,
affecting many very different groups throughout the animal kingdom. This trend has been …
