The Center for Tropical Research has recently developed new models in California to determine the amount of intraspecific genetic variation present in an area. Recently, we tested this new approach in the Santa Monica Mountains National Recreational Area (SMNRA), part of the southern subunit (2) of the California Landscape Conservation Cooperative.
The Partnership for International Research and Education project seeks to develop an integrated framework for conserving central African biodiversity under climate change that is both evolutionary-informed and grounded in the socioeconomic constraints of the region.
Region:Africa (Cameroon, Equatorial Guinea, Ivory Coast), Australia, South America (Ecuador) These projects seek to understand the mechanisms important in generating rainforest biodiversity. Results from research on birds in Cameroon and…
Ever since Darwin’s “The Origin of Species,” biologists have been studying the causes of diversification and speciation. Speciation may be driven by sexual or ecological selection or random drift, and…
