Environmental sensitivity in relation to size and sex in birds: meta-regression analysis.
Studies of animals often report a greater sensitivity of one sex to poor rearing environments. However, it is unclear whether size differences associated with sex, sex itself, or other factors are responsible for differences in performance. While the greater nutritional requirement of the larger sex is a plausible explanation for increased sensitivity (i.e., size-dependent vulnerability), other hypotheses suggest that size-independent traits may have effects on the fitness of offspring (i.e.,...Expand abstract
