Biotic factors influencing the unexpected distribution of a Humboldt marten (<i>Martes caurina humboldtensis</i>) population in a young coastal forest - Fig 5

Boxplots of inverse Simpson diversity index for A) all vertebrate species, B) potential Humboldt marten (Martes caurina humboldtensis) prey species (small mammals and birds) and C) carnivores and potential competitors, detected with camera traps across 4 vegetation types in coastal Oregon. The black lines denote the medians, x the average, and boxes the 25% and 50% quartiles.
