Hanski's model

Hanski's model describes how populations of species persist in fragmented habitats, called patches, over time. It suggests that successful species maintain a balance between local extinctions in individual patches and recolonizations from other patches. Factors like patch size, connectivity, and species dispersal abilities influence this balance. Larger or more connected patches are less likely to lose populations, while smaller or isolated patches face higher extinction risk. The model helps predict patterns of species distribution in fragmented landscapes and guides conservation efforts by highlighting the importance of maintaining habitat connectivity to support persistent populations.
