臺灣新紀錄外來種蚯蚓

Occurrence of the Exotic Earthworm Pontoscolex corethrurus (Muller) (Glossoscolecidae: Oligochaeta) in Taiwan

This paper describes Pontoscolex corethrurus (Muller), a new record of the glossoscolecid earthworm in Taiwan. This newly introduced species, originally endemic to tropic America, occurred in the coastal plain, piedmont and mountain (elevation to about 1,000m) regions of the island. It was a dominant earthworm in disturbed environments, such as banana plantations, betel nut plantations, fruit orchards, agricultural lands, and the Conservation Education Garden of Taiwan Endemic Species Research Institute. 本文描述一臺灣新紀錄種蚯蚓Pontoscolex corethrurus（Muller）。這個新引進物種原產於熱帶州，在臺灣自海岸平原至山麓地帶（海拔約至一千公尺）均有分布。在遭受人為干擾的環境，株香蕉園、檳榔園、果園、農耕地、生態園區之類的棲地中，此種蚯蚓常成為優勢物種。
