Robert Fisher is a principal investigator and conservation biologist with the U.S. Geological Survey’s Western Ecological Research Center. His focus has been on how natural systems are responding to the Anthropocene, and what types of resiliency they have or lack as it relates to maintaining ecological integrity and biodiversity. Additionally, through understanding individual species and community responses to perturbations through modern monitoring techniques, he and his team can determine appropriate management experiments or options to possibly recover resiliency. His work focuses on southern California where urbanization has been a major driver of ecological change and the tropical islands of the Pacific Basin that have also been impacted by human change and are on the front line as extreme recent weather variability. He has received a Ph.D. in Population Biology from University of California, Davis and a M.S. in Zoology from University of California, Davis.
