Document Summary

Set of subpopulations that are connected by dispersal or movements in and out of the region. There is always a core population where dispersal is the highest and emigration and it has the lowest risk of extinction. Metapopulation as a whole never changes but minor changes in sub pop. Suitable habitat that occurs in discrete patches:- it has to be large enough to support breeding populations: subpopulation cannot be too isolated, every subpopulation is substantially at risk of extinction ( including the largest subpop) 4. dynamics of subpopulation is not synchronized otherwise it will be one big pop. 3. if one pop goes extinct then it gets recolonized by a diffind of diff populations move into that one. If the immigration rate is high they wont distinct they will be function as one continuous population. If you have a large patch compared to small patch forest fire in small patch will destroy everything.
