Climate is generally considered the main factor determining the global distribution of plant and animal species.Climate changes, depending on their rapidity and intensity, can give rise to events of (local, regionalor global) extinction, redistribution of flora and fauna, population genetic divergence, ecotype differentiation or even speciation. That is, climate changes reflect on both ecosystem structure and function, as well as on spatial organisation of the borders between biogeographic units, and eventually also on the genesis of both ecosystems and biogeographic units itsel.Specific physical conditions working at a local scale (microclimate), such as rocky cliffs, watercourses or special types of rock, can enable the persistence of species in territories where the macroclimate is no longer appropriate for their occurrence.
