Response curves for environmental variables that provided greatest contributions to species distribution models for F. rusticus (A–D) and P. clarkii (E–H). Response curves analyze the range of a single variable’s values on the predictive power of a model. Curves show the mean response of the 10 replicate MaxEnt runs with occurrences from predictive models represented as “X” at 0.0 on the Y-axis.
