Hi everyone,
I thought I would just mention a paper that appeared recently in Nature
(Myers et al. 2000 Biodiversity hotspots for conservation priorities
403:853-858). It identifies biodiversity hotspots around the globe with
the aim of using a significant amount of conservation money to conserve
just these highly diverse regions. To qualify as a hotspot a region had to
contain .5% of the worlds plant species as endemics. The only Aus region
was SW Australia which contains by their measures 4331 endemic plants or
1.4% of the world total. They find that 44% of the worlds plants and 35%
of the vertebrates are found in only 1.4% of the land mass. They suggest
that significant conservation activities should be funnelled towards these
spots which are mostly under significant threat. It is a very interesting
article, not only for the conservation perspective but for the lists of
endemic vertebrates in each region. For instance they list the tropical
andes as containing a staggering 677 endemic bird species and wallacea as
249 endemic birds and 123 endemic mammals ( I could not work out which
taxonomies they were using but it is cetainly BSC and they don't consider
those elusive ultrataxons). If you can find a copy of Nature have a look.
Best Wishes
