Encelia

There are multiple hypotheses for the spectacular plant diversity found in deserts. We explore how different factors, including the roles of ecological opportunity and selection, pro- mote diversification and disparification in Encelia, a lineage of …

Natural selection is an important driver of genetic and phenotypic differentiation between species. For species in which potential gene flow is high but realized gene flow is low, adaptation via natural selection may be a particularly important force …

New paper shows how multiple ecological axes contribute to gradients of selection
