Document Summary
We can integrate the dynamics of populations, metapopulations and communities. We can study processes at the regional, or landscape, scale: moving back and forth from patches within metapopulations, 4 conditions that has to be satisfied of metapopulations. Metacommunities expand the concept of metapopulations: metacommunity is a set of local communities that are linked by the dispersal of multiple potential interacting species, range of different clich s. Species diversity is scale-dependent: measure and compare species diversities at the local scale, measure and compare species diversity at the regional scale. Patches experience different disturbances at different time. Patch size and species diversity correlation therefore influencing the diversity of metacommunity as a whole. Different time scales: alpha (local) diversity, gamma (regional) diversity. Which type of diversity do these graphs visualize: north america. How would a gyrfalcon or a butterfly experience their landscape: gyrfalcon perceives their environment differently from butterfly, butterfly uses smaller environment/smaller patch.
