1. Multi-population systems. In recent times more than before, human populations expand and require larger areas for agriculture and other land-use goals, often at the expense of natural ecosystems. Many organisms have to face large-scale habitat destruction and fragmentation of larger populations. CONCEPTUALDOMAINAND METAPOPULATIONAPPROACHES A fundamental assumption of the original metapopulation concept (Levins, 1969a) is that space is discrete and that it is possible and useful to distinguish between habitat patches that are suitable for the focal species and the rest of the environment, often called the matrix.

Metapopulations are conceived as spatially structured populations consisting of distinct units (subpopulations), separated by space or barriers, and connected by dispersal movements. Metapopulations characteristically demonstrate a turnover of local populations going extinct and becoming re-established, resulting in a distribution pattern that
