Natural selection on the genetical component of variance in body condition in a wild bird population

Abstract:

Although there is substantial evidence that skeletal measures of body size are heritable in wild animal populations, it is frequently assumed that the nonskeletal component of body weight (or 'condition') is determined primarily by environmental factors, in particular nutritional state. We tested this assumption by quantifying the genetic and environmental components of variance in fledgling body condition index (= relative body weight) in a natural population of collared flycatchers (Ficedul...
