Fig. 1.

Mean proportions (± SE) of total mass consumed by mountain cottontails (Sylvilagus nuttalli, white bars) and pygmy rabbits (Brachylagus idahoensis, grey bars) from a feeding station consisting of a diet of commercial rabbit chow containing a single monoterpene paired with a diet containing a mixture of monoterpenes. When the single monoterpene constitutes a 0.50 proportion of total food consumed, rabbits are considered to have no preference. An asterisk above bars denotes proportions consumed of the single monoterpene that were significantly different from 0.5 for each species with α = 0.05. A plus sign above sets of bars denotes a significant difference between species in the proportion consumed of the single monoterpene
