biography

Dr. Matthew Edwards is a coastal marine ecologist who specializes in rocky reef ecosystems throughout the Northeast Pacific Ocean. He received a BA in Aquatic Biology from UC Santa Barbara in 1990 and a MS in Marine Science from Moss Landing Marine Laboratories in 1996. He graduated with a Ph.D. from the University of California Santa Cruz in 2001 where he studied spatial scales of community organization in kelp forest ecosystems. He joined the faculty at San Diego State University in 2002 where he teaches courses in Marine Biology, Biostatistics, and General Ecology. His research has since focused on benthic ecology, with special attention tohow coastal ecosystems respond to environmental disturbances over broad geographic regionsand how ecosystem functioning is impacted by widespread losses of foundation species. His most recent work has focused on examining ways to sustainably harvest kelp in California and Chile for use in abalone aquaculture,and identifying land-based aquaculture techniques that will aid inreplenishing wild stocks of abalone that have declined in recent decades.This has involved working with aquaculture facilities to study how different parental diets and larval rearing conditions impact adult fecundity and larval settlement, respectively, and whether the ouplanting of laboratory-reared juvenile abalone is a viable method for enhancing their populations in the wild. He is also on the oversight committee for the new Aquaculture facility at Moss Landing Marine Laboratories, where they are establishing a place for the study of aquaculture in the California State University system.

 

Area of Interest

1)Marine ecology: scale-dependent regulation of subtidal kelp forests
2)Recruitment processes in marine macroalgae (with emphasis on the role of dormant stages)
3)Impacts of large  disturbances (El Niño-Southern Oscillations)
