Performance statistics of three top models of pathogen and toxicant exposure factors relating to ultimate cause of mortality for 67 fishers (Pekania pennanti) within the two isolated populations, northern California and southern Sierra Nevada.

The one factor in the final model was ARNUM (number of different types of anticoagulant rodenticides to which the fisher was exposed). TOXO_high refers to exposure to T. gondii using the isotype IgM.
