释义	biogeography /ˌbʌɪəʊdʒɪˈɒɡrəfi / /ˌbʌɪəʊˈdʒɒɡrəfi/ noun [mass noun] The branch of biology that deals with the geographical distribution of plants and animals.Alexander von Humboldt of course made lasting contributions to the fields of physical geography and biogeography, adding to our knowledge of plants, animals, and the earth.... Historical biogeography deals with phylogenetic patterns among species and higher lineages attributable to relatively ancient events in earth history. So long as its shortcomings are recognized, this book has a wealth of information on the distribution and ecological biogeography of birds. Derivatives biogeographer noun ... The objective is to bring ecologists, paleontologists, geneticists, biogeographers, and others together to think ambitiously and work on evolutionary problems on a broad scale. Most cladistic biogeographers have not been so explicit but have nevertheless implicitly assumed that correspondence to a general pattern implies that individual lineages existed at the same time. A phenomenon which fascinated Wallace, and has occupied generations of biogeographers ever since, is the sudden change in flora and fauna that occurs in the twenty-mile wide channel between the small islands of Bali and Lombok. biogeographic /ˌbʌɪəʊdʒɪəˈɡrafɪk/ adjective ... There are a variety of phylogenetic biogeographic methods. But because they do not advocate this practice, they review island biogeography and biogeographic principles of reserve design in separate, widely spaced chapters. Second, the results of standard cladistic biogeographic analyses, which may combine groups of different ages, cannot be unambiguously attributed to any particular cause. biogeographical /ˌbʌɪəʊdʒɪəˈɡrafɪk(ə)l/ adjective ... Finally, we propose a biogeographical hypothesis of speciation events within the N. mediocris species complex. However, robust inferences can be made from a combination of molecular genetic, biogeographical and palaeontological studies. The biogeographical affinities of the fauna are thus not clear. biogeographically /ˌbʌɪəʊdʒɪəˈɡrafɪkli/ adverb ... This paper is the first in a series of studies re-describing echinoderm taxa from these biogeographically important Paleozoic assemblages. These taxa are biostratigraphically and biogeographically significant and are discussed more fully below. Furthermore, trilobite faunas in the Early Cambrian were already differentiated biogeographically.
