The recognition of patchy and heterogeneous landscapes has been important in the ecology of communities, this has allowed to evaluate in a more realistic way their dynamics and structure in a hierarchy of interrelated spatial scales (local and regional) within a scheme of metacommunities, where species in local communities potentially...
Dispersal is a main component if plant populations and community invasiveness. Feasibility of propagles to reach safe sites for establishment depends on dispersal. Besides, it allows species persistence in low-density patches, habitat recolonization, and it promotes genetic and species diversity in metacommunities. In this dissertation I present species and local...
