Biogeography should be outlined easily because the research of the geographical distribution of organisms, yet this straightforward defmition hides the nice complexity of the topic. Biogeography transcends classical topic parts and includes quite a number clinical disciplines that incorporates geogra­ phy, geology and biology. no longer unusually, for that reason, it skill really various things to varied humans. traditionally, the examine of biogeogra­ phy has been centred into cubicles at separate issues alongside a spatio-temporal gradient. At one finish of the gradient, ecological biogeography is worried with ecological strategies taking place over brief temporal and small spatial scales, when on the different finish, historic biogeography is anxious with evolutionary procedures over hundreds of thousands of years on a wide, usually international scale. among those finish issues lies a 3rd significant compartment involved in the profound results of Pleistocene glaciations and the way those have affected the distribution of modern organisms. inside every one of those cubicles alongside the dimensions gradient, numerous theories, hypotheses and versions were proposed in an try and clarify the current and prior biotic distribution styles. To a wide volume, those cubicles of the topic were non-interactive, that is comprehensible from the several pursuits and backgrounds of some of the researchers. however, the distribu­ tions of organisms around the globe can't be absolutely understood and not using a wisdom of the whole spectrum of ecological and old tactics. There are not any levels in biogeography and this day' s biogeographers are essentially born out of a few different discipline.

Assumptions are the basis of modelling, and modelling is a fundamental part of science. As it would seem to be impossible to collect data and infer patterns without reference to some kind of model, we should acknowledge the value of modelling, though at the same time we must try to make our models internally consistent, modifying or rejecting them as quickly and open-mindedly as possible in the light of further investigation. Some of A perceptual overview 31 this investigation may take the form of testing, whether by induction or deduction, and some will consist of explorations and improvements to the theoretical side of the model.

This state of affairs is all too familiar in biogeography. A concerted attempt to perceive biogeographical processes as a whole, but at the same time to be aware of levels within the biogeographical investigation when studying a particular problem, would undoubtedly help to clarify and unify biogeography. Three important examples of level are taxonomic rank, time scales and spatial scales. By analogy with mechanics, in which vectors can be resolved along any axis we choose, we can similarly resolve biogeographical processes on any scale we choose and direct our researches accordingly.
