Mark A Ricca
I have spent my USGS career focused on addressing science needs of resource managers and agencies across a wide range of ecosystems by integrating concepts from population, community, and ecosystem ecology.
My experience spans ecological systems ranging from desert wetlands in California to sub-arctic islands in Alaska to rangelands of the American West. I now help facilitate science production for principal investigators at FRESC.
