Evolutionary responses to environmental heterogeneity in central american echinoid larvae: plastic versus constant phenotypes.

Abstract excerpt

Do changes in food resources lead to evolutionary changes in phenotypic plasticity or in different constant phenotypes? I addressed this question by studying plasticity of larval feeding arms for "geminate species pairs" in three echinoid genera. These closely related species were geographically isolated when the Panamanian Isthmus raised 2.8-3.1 million years ago, creating two different food level environments:...
