Figure 6 in Odorants Differentiate Australian Rattus with Increased Complexity in Sympatry

Figure 6. Variation in chemical complexity of preputial gland extracts among four subspecies of Rattus fuscipes and R. leucopus based on 80 quantitated compounds. (A) Box and whisker plots of the number of chemical compounds detected in each subspecies. (B) Box and whisker plots of the total abundance of chemical compounds detected in each subspecies. In both, asterisks above pairwise comparisons of conspecific subspecies indicate significantly higher values (p <0.01) with a one-way Mann-Whitney U Test for all sympatric to allopatric comparisons.
