黃頸透鈣蚓入侵森林生態系之影響文獻回顧

A Review on the Impacts of the Invasive Earthworm, Pontoscolex Corethrurus, on Forest Ecosystems

摘要


外來生物的入侵是造成生物多樣性喪失及生態系劣化的一個重要因子;然而此議題多半忽略地底下的入侵生物,例如入侵蚯蚓。近年來發現一種原產熱帶美洲的蚯蚓-黃頸透鈣蚓(Pontoscolex corethrurus)也已入侵台灣,其對台灣本地蚯蚓及生態系的影響目前並不清楚。本文回顧國外黃頸透鈣蚓入侵對森林生態系造成的衝擊,包括土壤物理結構、碳氮循環、土壤生物相等,並且認為其對台灣森林生態系的影響不容忽視。因此建議應儘速對其分布及影響進行評估,以做為相關單位未來進行管理與防治之依據。

並列摘要


Invasive species is an important cause for loss of biodiversity and degradation of ecosystems. However, researches on invasive species often ignore the belowground invasive species, for example, the earthworms. In recent years, an invasive earthworm, Pontoscolex corethrurus, originated from South America has been found and widely distributed in Taiwan. This paper reviews studies on the impacts of P. corethrurus on forest ecosystems, including those on soil physics, nutrient cycling, and soil biota. We suggest the potential impacts of this invasive earthworm on Taiwan’s forest ecosystems should not be ignored and urge for assessments on its distribution and impacts on the ecosystems for future management.
