Dr. Wildhaber is a research ecologist and Quantitative Ecology Section Chief at the Columbia Environment Research Center. His research focuses on all areas of freshwater and marine aquatic ecology, fish biology, behavioral ecology, ecological modeling, ecotoxicology, and climate change in support of conservation, recovery, and restoration efforts and population estimation of crayfish, fish, birds, and mammals. His expertise includes: at-risk, threatened, endangered, and invasive fishes and crayfishes; reproductive ecology; bioenergetics; population, community, and ecosystem modeling with changing environments and stressors; population monitoring and experiment design; and Bayesian and non-Bayesian approaches data analysis. His research includes reproductive behavior and physiology and abiotic and biotic effects on reproduction of commercially valuable and/or at-risk, and federally-listed as threatened or endangered freshwater and marine organisms; effects of heavy metals and acidic contamination on riverine ecosystems; effects of water management riverine benthic fish communities; improved methods of counting mammals; identification of chemical attractants for control of invasive carp and crayfish through electro-olfactogram techniques and behavior; and spatial and temporal hierarchical fish population modeling using spatially-explicit and/or individual-based models under varying environmental conditions and/or contaminants in the context of global climate.
