Paleontological Society of Washington: Fraser on climatic and biotic interchange

The Paleontological Society of Washington

7:00 pm, Wednesday, September 21

National Museum of Natural History, Constitutional Ave. entrance

The roles of climate and biotic interchange in the assembly of mammal communities

Danielle Fraser

Smithsonian National Museum of Natural History

Climate, speciation, extinction, and invasion are thought to structure patterns of species diversity. I use phylogenetic community assembly metrics to understand mammal responses to long-term climate and faunal changes during the Cenozoic (66 Ma – present). My research is a critical step in answering “What factors have led to the emergence of communities as we know them today?” and in generating predictions for the impact of human-driven extinction on modern community assembly.

Non-Smithsonian visitors will be escorted to the Q?rius auditorium at 6:50 and 6:55 p.m. Society members will host the speaker for dinner at the Elephant & Castle (1201 Pennsylvania Ave.) prior to the meeting. Members may meet at the restaurant or inside the Constitutional Ave. entrance of the NMNH at 5:00 and walk to the restaurant as a group.
