报告人简介：
Dr. Dolph Schluter now is working at Zoology Department, University of British Columbia as a Professor and Tier I Canada Research Chair. He got his Ph. D at University of Michigan and did his postdoctoral research at University of California, Davis and University of British Columbia. He is a foreign fellow of US National Academy of Sciences, member of American Academy of Arts and Sciences, fellow of The Royal Society of Canada. He is also the president of American Society of Naturalists and Society for the Study of Evolution. Prof. Schluter’s research is mainly focused on evolutionary ecology and quantitative methods in ecology. He has published a great number of papers in top ranking journals, especially in Science and Nature. He has also published several books such as THE ANALYSIS OF BIOLOGICAL DATA and SPECIATION AND PATTERNS OF DIVERSITY. For more information, welcome to his website:

报告内容简介:
Evolutionary processes have shaped the development of Earth's major biodiversity gradients, such as the latitudinal gradient in species richness. Evolutionary hypotheses to explain such global patterns are based on the idea that rates of origin of new species (speciation), and rates of new species accumulation (diversification), are highest where species diversity is greatest. However, a review of existing evidence suggests that diversification rates are similar between latitudes, and that speciation rates might be highest where species diversity is low. I attempt to reconcile these ideas and observations with our understanding of the dynamic history of biodiversity gradients.
