Fragmentation Flashcards
Smaller fragments result in an
Increased ratio of edge forest to core forest.
Fragmenting a stand of tropical forest may
Encourage speciation (Producing two distinct species).
The microclimate of the edge and core forest are
Very different - The interior forest microclimate is more stable than the forest edge.
The interior is less affected by
Changes in wind speed and fluctuations in temperature and humidity.
Some species are restricted to the forest core, some
To the forest edge.
Forest core species will be left isolated in
Smaller patches, with smaller population sizes, meaning they are at a higher risk of extinction by chance reductions in population, such as disease outbreak.
The reduction in population size can lead to
The loss of genetic variation, resulting in limited reproduction.
Fragmentation results in
Lower species richness and a reduction in breeding success of some species.
Circular fragments up to
12.6 ha (126’000 m2) have no core forest.
