"Integrating multiple classes of data to reconstruct past events - from the first communities of multicellular organisms in the Ediacaran to Holocene Extinction on the California Coast"
Abstract: Synthetic reconstruction of biological processes and events in their geologic context provides new research opportunities. However, there are often communication and pedagogical challenges given the differences in approaches in biology and geology, and the different training of biologists and geologists. Here, I explore a series of vignettes that hopefully illustrate some of these opportunities and challenges: 1) Are oxygen and cold the same thing in evolution? Placing events in earth history including the Ediacaran/Cambrian radiation, Phanerozoic mass extinction, and anthropogenic climate change in a common framework; 2) Sequencing and isotope investigation of dead ducks, implications for endangerment of the living and reconstructing the impacts of extinct forms on California Coastal Ecology; and 3) Historic landscape processes and modern Estuaries and Lagoons.
