  Stepping stones are a series of discontinuous small patches that provide resting places and food for species in movement, increasing structural connectivity between large fragments. They also increase landscape heterogeneity, stimulating bouncy movements for many species’ dispersal, especially birds.

Habitat Fragmentation and evolution[]

Once habitat fragmentation is one of the major threats to biodiversity, understanding dispersal effects of species is important to understand their evolution. 


Stepping stones and corridors are strategies used to manage the effects of habitat fragmentation, such as the decrease in gene flow between populations. With connectivity between fragments, the higher is the rate of gene flow. Thus the less will be the subpopulation isolation, the inbreeding and extinction rate.
