Life-history traits of extinction-prone and invasive fish species
My collaborators at Kansas State University (Keith Gido and Walter Dodds) and I developed a database of quantitative estimates of 14 life-history traits (e.g. size at maturation, egg size, clutch size, growth rates, longevity) for more than 100 fish species recorded in Kansas since 1885. Using this comprehensive database, we are examining patterns of life-history variation among different ecological classifications for these Great Plains taxa, and have developed predictive models which identify specific traits and non-linear combinations of traits that render species extinction-prone or facilitate establishment of non-natives in two Great Plains basins of western Kansas.
