Meyer III (Marty) is Director of PRISSM – the Partnership of Regional Institutions for Sage Scrub Monitoring, which in addition to butterflies, includes monitoring of plants, birds, other vertebrates, and weather. Marty is also Director of the Claremont Colleges’ Bernard Biological Field Station and Assistant Professor of Biology at Pomona College. Marty’s research explores the fields of conservation biology, invasion biology, biogeography and ecology, including aspects of population, community and ecosystem ecology. Currently his work is focused on understanding how and why the species composition of local biotas are changing and how such changes directly and indirectly affect ecosystem-level processes and properties, as well as preservation and restoration of sage scrub ecosystems.
