影响因子Biogeography may be defined simply as the study of the geographical distribution of organisms, but this simple defmition 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 pat

W. Wunderlich,H. Springer,W. Goebelsequence of this is that, again in general, larger areas will contain more species than smaller areas. However, the species—area relationship is not simply a reflection of different distribution patterns. As will be seen, it can also arise from sampling a set of species all with the same distributions but with different abundances.

E. Stein,K.-H. Lambertz,L. Plankiogeographers, evolutionary biologists and ecologists in general. Whilst both plants and animals can be endemic, this chapter will use plants as examples although notable differences do exist (Harper, 1968). A historical discussion of plant endemism is given by Prentice (1976).

Valid Discretization via Renewal Theory,1986). Among fossilizable marine organisms about 72% of the families (2 400 of 3 300) and 78% of the genera (9 250 of 11 800) are known to be extinct (Raup and Sepkoski, 1982, 1986). It is estimated that 63 species and 52 subspecies of mammals, and 88 species and 83 subspecies of birds have become extinct since AD 1600 (Diamond, 1984c).

Species diversityal patterns of species diversity, but the latitudinal gradient from the teeming richness of the tropics to the stark barrenness of the poles remains one of the most striking features of the distribution of life on earth — and one of the least well understood.
