翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Acacia aneura ： ウィキペディア英語版 Acacia aneura ''Acacia aneura'', commonly known as mulga or true mulga, is a shrub or small tree native to arid outback areas of Australia, such as the Western Australian mulga shrublands. ==Description== Mulga is highly variable, in form, in height, and in shape of phyllodes and seed pods. It can form dense forests up to 15 metres high, or small, almost heath-like low shrubs spread well apart. Most commonly, it is a tall shrub. Because it is so variable, the taxonomy of the mulga has been studied extensively, and although it is likely to be split into several species eventually, there is as yet no consensus on how or even if this should be done. Although generally small in size, mulga is long-lived, a typical life span for a tree undisturbed by fire is on the order of 200 to 300 years. Mulga has developed extensive adaptations to the Australian desert. Like many ''Acacia'' species, it has thick-skinned phyllodes. These are optimised for low water loss, with a high oil content, sunken stomata, and a profusion of tiny hairs to reduce transpiration. During dry periods, a mulga drops much of its foliage to the ground, which provides an extra layer of mulch and from where the nutrients can be recycled. Like most Australian ''Acacia'' species, mulga is thornless.〔(Arid Zone Trees )〕 The needle-like phyllodes stand erect to avoid as much of the midday sun as possible and capture the cooler morning and evening light. Any rain that falls is channeled down the phyllodes and branches to be collected in the soil immediately next to the trunk, providing the tree with a more than threefold increase in effective rainfall. Mulga roots penetrate far into the soil to find deep moisture. The roots also harbour bacteria that fix atmospheric nitrogen and thus help deal with the very old, nutrient-poor soils in which the species grows. 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「Acacia aneura」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.
