St. Nick,
Generally the biodiversity hotspots are tropical or semi-tropical island
systems with very high mountains. Such sites have a large spread of unique
climatic and orthographic conditions. In addition, if by chance or migration
continental species land on such ecosystems they quickly speciate. An example:
the American robin landed in Hispanola and over hundreds of year speciated,
a to become the Laselle Thrush (Turdus swalesi), and more than 30% of the
flora on Hispanola is endemic including Salvia paryskii , a tree. The island
has 11 ecozones.
cheers Paul.
