Mark Wildhaber, PhD

Dr. Mark Wildhaber is a Research Ecologist at the Columbia Environmental Research Center.

Mark has worked at USGS, Columbia Environment Research Center since 1991. His major responsibilities include research in all areas of aquatic ecology, fish biology, behavioral ecology, ecological modeling, and climate change in understanding for and support of conservation and recovery efforts. His expertise includes: at-risk, threatened, and endangered fishes, reproductive ecology, bioenergetics and population, community, and ecosystem modeling and forecasting, population monitoring and experiment designs, and Bayesian and non-Bayesian approaches to analyzing fisheries data. Mark's research includes reproductive behavior and physiology and abiotic and biotic requirements for reproductive success of commercially valuable and/or federally-listed as threatened or endangered fishes; effects of heavy metals and acidic contamination on riverine ecosystems; effects of water management on the benthic fish community of riverine ecosystems; effects of organic and inorganic contamination on aquatic benthic invertebrate communities; and spatial and temporal hierarchical fish population modeling using spatially-explicit individual-based models that incorporate bioenergetics, foraging theory, and other models of habitat choice under varying environmental conditions in the context of global climate to guide conservation and recovery efforts.
