Brain Size and the Diversification of Body Size in Birds

The American Naturalist, 2008
Large brains are associated with increased cognitive skills, enabling animals to use new environments and resources more successfully. Such behavioral flexibility is theoretically expected to have macroevolutionary consequences. First, populations of big-brained individuals should more easily become established in new locations, increasing ...

Pelvic dimorphism in relation to body size and body size dimorphism in humans

Journal of Human Evolution, 2011
Many mammalian species display sexual dimorphism in the pelvis, where females possess larger dimensions of the obstetric (pelvic) canal than males. This is contrary to the general pattern of body size dimorphism, where males are larger than females.

On body size of infected mice

Acta Tropica, 2007
Coutinho et al.'s experimental observation reveals that infected mice gain higher body weight. A theoretical analysis is given to explain the phenomenon, the result agrees remarkably well with Coutinho et al.'s experimental data (Acta Tropica 101, 2007, pp. 15-24).

Body size

1995
Abstract Variation in body size has been widely studied by evolutionary biologists, in part because it is relatively easy to measure. In diverse animal taxa, especially those with indeterminate growth, an individual’s size is an overwhelming predictor of its social status, relative fecundity, or probability of survival.

Body Size Estimation in Bulimia

British Journal of Psychiatry, 1986
Body size estimation was studied in 22 patients with bulimia and 20 normal controls. Two methods of body size estimation were used, a distorting television image method (DTIM) and the image marking method (IMM). The subjects estimated body size of a dummy as well as their own body on the DTIM.

Body size, mortality, and longevity

Journal of Theoretical Biology, 1983
The body-size dependent relationships of mortality and longevity are examined for birds and eutherian mammals. Differences between mass exponents for maximum recorded longevity and survival times for fractions of original adult populations confirm the age-dependence of mortality in both classes and a size-dependency of population-age distribution.

Some consequences of body size

American Journal of Physiology-Heart and Circulatory Physiology, 1984
The question of the proper size denominator for metabolic indices is addressed. Metabolic rate among different species is proportional to the 3/4 power of body weight, not surface area. Muscle power also varies with the 3/4 power of weight, suggesting that metabolic rate is determined mainly by muscle power.
