The abundance of earthworm in the agroecosystem of Sunyu Island was estimated on the basis of 1,025 individuals collected in August and October, 2007. Material were collected from litter layers and soils by hand sorting and digging. They encompassed 12 species, 4 genera, and 3 families. Species composition and abundance were as follows: Amynthas heteropodus 29.7%, Aporrectodea tuberculata 22.6%, Aporrectodea caliginosa 19.5%, Drawida japonica 11.3%, Amynthasagrestis 5.0%, Amynthas hupeiensis 3.6%, Aporrectodea sp. 3.5%, Amynthas corticis 2.0%, Bimastos parvus 1.6%, Amynthas koreanus 0.8%, Amynthas hilgendorfi 0.2%, and Amynthas sp. 0.2%. Of 537 individuals, A. heteropodus, and A. tuberculata were the most numerous members with abundance of 52.4%. The clitellate vs. aclitellate ratio of the earthworm was approximately 1:1.1. |
