A geographical division based on the characteristics of the biota in each region. It varies somewhat depending on the animal, plant, and taxonomic group, and is generally called a zoogeographical region for animals and a flora region for plants. Classically, taxonomic geographical divisions were made based on taxonomy, but in recent years ecological factors have also come to be taken into consideration. This is because the distribution of living things is both geographical (locational) and ecological (environmental). In addition, biological divisions of the oceans are also made based on marine life, ocean currents, water temperature zones, etc. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
各地の生物相の特徴を基にした地理的区分。動物,植物,さらにその分類群によって多少異なり,一般に動物の場合は動物地理区,植物の場合は植物区系と呼ばれる。古典的には分類学に基づき分類地理学的な区分がなされたが,近年では生態学的要素も考慮されるようになってきた。生物の分布が,地理的(場所的)であるとともに生態的(環境的)であるからである。なお,海洋についても,海洋生物,海流,水温帯などから,生物学的海区区分がなされる。
