Evolution on the Pacific Coast-from Oceanography and Tectonics to Endangerment and Restoration in Estuaries
Wednesday — February 17, 2010
Pacific Forum — 3:00 p.m.
My presentation starts with a few images of this range of work including gene expression in jellyfish sensory structures from our ongoing Evolution and Development work but the major theme will be a succession of treatments at increasingly more recent temporal scales relating to the origins of biodiversity and genetic structure along the Pacific Coast. These start with an argument that aspects of the unique faunal diversity of the temperate northeast Pacific are the product/relict of the crescendo of upwelling that occurs in the late Miocene. Geologic and molecular data are then integrated to explain evolution of aspects of the endemic fauna of the Gulf of California in their tectonic and seaway connectivity contexts. Details of genetic structure of estuarine taxa are then associated with the more recent evolution of the California coast and the critical importance of historical ecology in the restoration of California estuaries is treated.
