1913Jrnl. Ecology I. 20 These climate-zones..are limited by biochores or plant-climate boundaries as suggested by Köppen. 1934A. G. Tansley in tr. Raunkiaer's Life Forms of Plants p. xiii, The ‘biochore’.., originally Köppen's term and analogous to the climatological terms isotherm and isohyet, is the line passing through all the areas whose floras show the same percentage number of a characteristic life-form: biochores can only be determined by the analysis of a large number of adjacent local floras. 1937Allee & Schmidt tr. Hesse's Ecol. Animal Geogr. ix. 137 Regions with a general similarity of habitus are recognized as biochores, which may be united as superbiochores or subdivided into subbiochores; areas within the biochores which have uniform external habitat conditions are biotopes. 1957P. Dansereau Biogeography iii. 125 The biochore is the geographical environment where certain dominant life-forms appear to be adapted to a particular conjunction of meteorological factors... Each biochore is characterized by a major type of vegetation... Within each biochore there develops one or more formations which extend over an entire province. |
