Figure 1
(Upper) Two sympatric species with broadly overlapping distributions of resource use. If resources are limiting, then natural selection may favor individuals in each species with traits that allow each of them to use that portion of the resource spectrum not used by the other species, as indicated by the arrows. (Lower) The result may be that the species diverge in trait value and resource use, thus minimizing competition for resources.

Body size (as represented by snout-vent length) in allopatric and sympatric populations of the two species. In allopatry, populations are similar in size, but in sympatry, P. hoffmani is larger and P. cinereus is smaller (data courtesy of D. C. Adams).
