宜蘭縣蚯蚓種類與分佈
The Species Composition and Distribution of Earthworms in Ilan
摘要
本調查為宜蘭縣第一次蚯蚓普查，從2002 年1 月至2002 年12 月，為期一年，共採得42 種標本，分別屬3 科4 屬，其中2 種新種、13 種已知種，其餘27 種則無法確定種類。蚯蚓種類分佈明顯受人為開發程度影響。新發現的種類大多採集於南澳、棲蘭及明池等地，因此推測在其他交通不便，尚少人為開發利用的地區，應仍有許多新的蚯蚓種類尚待發現。外來種蚯蚓南美鞍帶蚓Pontoscolex corethrurus 在宜蘭縣分佈廣泛，除少數人為干擾較少的地區外，均可發現其蹤跡，連離島的龜山島及保留區的福山植物園皆有分佈，顯見其在台灣擴散的程度已經非常廣泛。部分採集點甚至僅能採得此種蚯蚓，顯示其可能已影響到台灣原生蚯蚓的生態。
並列摘要
This investigation is the first time to survey of the earthworm fauna in Ilan county. In this survey, we found 42 species belonging to 4 genera and 3 families in Ilan. In addition to the 2 new species and 13 known species, the other 27 species could not be identified. Earthworm distribution in Ilan is significantly affected by human activities. Because most of the unknown species were collected in Nanau Shiang and Datung Shiang , which most area remain under-development, we suspected that there will be many new species in the place without exploitation. The exotic earthworm, Pontoscolex corethrurus, is widely distributed in Ilan. We can find them in many places, including Fu-Shan Research Station and Kuei-Shan Island. In some place, the exotic earthworm would appear alone without any other earthworm species. It shows the exotic earthworm might make impact on earthworm ecology in Taiwan already.
