Maternal nutritional condition and genetic differentiation affect brood size and offspring body size in Nicrophorus.

Abstract excerpt

In most animal species, brood size and body size exhibit some variation within and between populations. This is also true for burying beetles (genus Nicrophorus), a group in which the body size of offspring depends critically on the number of offspring competing for food due to the discrete nature of resource used for larval nutrition (vertebrate carcasses). In one species, brood size and body size are correlated...
