Fragmentation
can cause isolation of patches from other remnant patches. The time since isolation,
the distance from other remnants, the degree of connectivity and the characteristics
of the surrounding landscape, are important for determining the effect of isolation.
Simply
the presence of species in a remnant is no guarantee of its continued existence
there. It may be necessary to look at the age structure of species to determine
whether it is likely to survive in a remnant.
Isolated remnants will have lost some original species(or be losing them) and gained some invading ones (or be gaining them). Therefore, it is important to look at species composition as well as species numbers to examine the full effect of isolation
