A deep-time perspective on macroecology
My talk will unite paleontological and neontological data to disentangle the long-term evolutionary responses of species to environmental change. Examining species’ responses on both short and long time scales is vital for elucidating the mechanisms controlling evolutionary processes, and for assessing how current and future climatic changes will impact Earth’s biodiversity.
More specifically, I will focus on empirical and simulation research that examines (1) the degree to which coarse scale abiotic environmental tolerances of species evolve through time within lineages; (2) whether the impact of ecological traits on diversification is dependent on rates of environmental change; and (3) the causal mechanisms responsible for latitudinal diversity gradients. Such studies provide a bottom-up perspective on the generation and maintenance of biodiversity under climate change, offering a better understanding of the interaction of species’ intrinsic macroecological characteristics with a dynamic extrinsic climate.
