Correlates of male fitness in captive zebra finches--a comparison of methods to disentangle genetic and environmental effects.

BMC evolutionary biology - 8 Nov 2011

Bolund Elisabeth, Schielzeth Holger, Forstmeier Wolfgang

Abstract excerpt

BACKGROUND: It is a common observation in evolutionary studies that larger, more ornamented or earlier breeding individuals have higher fitness, but that body size, ornamentation or breeding time does not change despite of sometimes substantial heritability for these traits. A possible explanation for this is that these traits do not causally affect fitness, but rather happen to be indirectly correlated with...
