Phylogeography and environmental correlates of a cap on reproduction: teat number in a small marsupial, Antechinus agilis.

Molecular ecology - 1 Mar 2007

Beckman J, Banks S C, Sunnucks P, Lill A, Taylor A C

Abstract excerpt

Natural selection should optimize litter size in response to the distribution and abundance of resources during breeding. In semelparous, litter-bearing antechinuses, teat number limits litter size. Consequently adaptation has been inferred in explaining intraspecific, geographic variability in teat number for several Antechinus spp. The phylogeography of teat number variation and associated genetic divergence...
