Document Summary
Meta populations are parts of a populations that are separate from each other in terms of area, location, etc. (a population of populations) Barriers may make it so that these populations cannot intermingle and they may have different behaviors. Some have more or less risk and variability in fitness. Escape locally bad conditions like overcrowding, vicious predators, or toxic environment. Patch size is largely relative to the species" mobility. Biggest impact that humans are having on the environment is fragmentation. Environments were not always patchy, but now they are . F = inbreeding coefficient = probably that 2 alleles are identical by descent. Fit = total for all populations (1- fit) = (1- fst)(1- fis) Higher fst higher differentiation among populations, so metapopulation is isolated.
