If your work involves ecology, evolution or conservation biology, it's quite likely that you've heard of Professor Rosemary Gillespie of the University of California, Berkeley.But if you're working in the field of island biogeography, it's almost certain you know her.Rosie is a brilliant and highly prolific scientist, uniting a rare combination of big-picture thinking and mastery of details.Her contributions to the literature include several hundred research papers, numerous reviews, book chapters and several influential books (e.g., Gillespie and Clague 2009).These publications span an impressive diversity of topics and include many groundbreaking findings and textbook examples taught in biogeography classes around the world.Rosie's work has encompassed multiple groups of organisms and many different island ecosystems, but her true love undeniably lies in the Hawaiian Islands and their diverse spider communities.
