Every species occupies a niche in its native ecosystem; some species fill large and varied roles, while others are highly specialized. Some invading species fill niches that are not used by native species, and they also can create new niches .To avoid intense temperatures, the majority of small desert mammals are nocturnal, and form burrows in which they live in. These burrows help maintain the mammals temperature due to the cooler environment from the soil. An example of this type of mammal is a desert centipede.
