sympatric populations of species with similar ecological niches
As you study two closely related predatory insect species, the two-spot and the
three-spot avenger beetles, you notice that each species seeks prey at dawn in areas
without the other species. However, where their ranges overlap, the two-spot avenger
beetle hunts at night and the three-spot hunts in the morning. When you bring them
into the laboratory and isolate the two different species, you discover that the
offspring of both species are found to be nocturnal. What have you discovered an

In some rocky intertidal habitats, the barnacle Chthamalus can survive across the
same depths as can the barnacle Balanus. However, where the two occur together,
Chthamalus adults are found only in the more stressful upper portions of the habitat
where they are more prone to desiccation. What is this is an example of?
