All of these studies involve interactions between species that could lead to competition, making them relevant for a community ecologist studying competitive interactions. Nest site selection can indicate competition for resources among birds, grass species preference shows potential food competition between antelope and bison, and stomach analysis of trout can reveal direct dietary overlaps indicating competition for food.
