''Banksia'' has a number of adaptations that have so far enabled the genus to survive despite dry, nutrient-poor soil, low rates of seed set, high rates of seed predation and low rates of seedling survival. These adaptations include proteoid roots and lignotubers; specialised floral structures that attract nectariferous animals and ensure effective pollen transfer; and the release of seed in response to bushfire. The arrival of Europeans in Australia has brought new ecological challenges. European colonisation of Australia has directly affected ''Banksia'' through deforestation, exploitation of flowers and changes to the fire regime. In addition, the accidental introduction and spread of plant pathogens such as ''Phytophthora cinnamomi'' (dieback) pose a serious threat to the genus's habitat and biodiversity. Various conservation measures have been put in place to mitigate these threats, but a number of taxa remain endangered. ==Background== (詳細はgenus of around 170 species in the plant family Proteaceae. An iconic Australian wildflower and popular garden plant, ''Banksia''s are most commonly associated with their elongate flower spikes and fruiting "cones", although less than half of ''Banksia'' species possess this feature. They grow in forms varying from prostrate woody shrubs to trees up to 30 metres tall, and occur in all but the most arid areas of Australia. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ecology of Banksia」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
