Biodiversity of Macadamias and Relatives

Macadamias and their relatives in the southern hemisphere plant family Proteaceae include 3 of the 10 largest flowering plant genera in Australia (Grevillea, Hakea, and Banksia). With colleagues in Australia, the lab is inferring a time-calibrated phylogeny for the group with which we are addressing hypotheses related to its biogeography and the evolution of ecologically relevant traits (e.g., those involved in pollination, dispersal, and phosphorus homeostasis).
