Ecological niche similarity tests: a Background similarity tests were developed in a series of two-way comparisons. Occurrences (y-axis) were compared against the backgrounds of each other species (x-axis). Gray fill indicates that the null hypothesis of no difference between niches was not rejected (p > 0.05), and white squares denote hypothesis rejected; b Convex polyhedrons derived from occurrences of each rodent species (yellow) and human HPS cases (red) in a multidimensional environmental space (principal components 1, 2, and 3, obtained from the original bioclimatic layers). Note that the environmental space occupied by human cases are contained within the set of environments used by the rodent species
