Abstract

Dispersal involves the movement of individuals between established populations or colonisation of uninhabited areas and is a key organising process underpinning patterns in populations and communities. Dispersal is a fundamental component of metapopulation and metacommunity theory, central to explaining the underlying the patterns of abundance and distribution of species, both spatially and temporally. Furthermore, dispersal is a main determinant of community assembly, governing how communities are constructed and maintained through immigration. Barriers that limit or prevent species from dispersing to a location can have a major influence on population dynamics and how communities assemble..
