Biogeography may be defined simply as the study of the geographical
distribution of organisms, but this simple definition hides the
great complexity of the subject. Biogeography transcends classical
subject areas and involves a range of scientific disciplines that
includes geogra phy, geology and biology. Not surprisingly,
therefore, it means rather different things to different people.
Historically, the study of biogeogra phy has been concentrated into
compartments at separate points along a spatio-temporal gradient.
At one end of the gradient, ecological biogeography is concerned
with ecological processes occurring over short temporal and small
spatial scales, whilst at the other end, historical biogeography is
concerned with evolutionary processes over millions of years on a
large, often global scale. Between these end points lies a third
major compartment concerned with the profound effects of
Pleistocene glaciations and how these have affected the
distribution of recent organisms. Within each of these compartments
along the scale gradient, a large number of theories, hypotheses
and models have been proposed in an attempt to explain the present
and past biotic distribution patterns. To a large extent, these
compartments of the subject have been non-interactive, which is
understandable from the different interests and backgrounds of the
various researchers. Nevertheless, the distribu tions of organisms
across the globe cannot be fully understood without a knowledge of
the full spectrum of ecological and historical processes. There are
no degrees in biogeography and today's biogeographers are primarily
born out of some other discipline."
