This Friday at 3PM, Bruce MacFadden will be giving a joint EEB/EES seminar about “Miocene Mammals from Panama: Tropical Refugium or Cradle of Biodiversity?”  MacFadden is an expert on “paleobiology, macroevolution, and paleoecology of Neogene mammals (particularly herbivores) of the Americas.”  His diverse research efforts have produced important insights on the biotic impacts of global climate change (DeSantis et al. 2009), discovery and description of new fossil taxa (MacFadden 2009), and a high profile review of the evolutionary history of iconic fossil horses (MacFadden 2005).
