山东半岛与辽东半岛蚯蚓生物多样性研究

于2009年在我国的山东半岛和辽东半岛地区采用挖掘法对这些地区不同类型生境采集到的蚯蚓的生物多样性进行了系统调查。野外采集到的蚯蚓置于潮湿土壤带回驻地,在采集当日用70%酒精处死,保存于95%酒精以备研究。部分形态分类特征明显的蚯蚓个体作为模式标本保存于10%福尔马林溶液。本研究据此提供了该地区最新的蚯蚓资源名录。在山东半岛发现陆栖蚯蚓3科6属13种,以巨蚓科(占种类总数的39%)、正蚓科(占种类总数的39%)为主;在辽东半岛调查共发现3科7属16种,以正蚓科(占种类总数的44%)、巨蚓科(占种类总数的31%)为主。作为蠕虫养殖业中的赤子爱胜蚓,在野外环境中也有分布。

Study of biodiversity of earthworm in Shandong and Liaodong Peninsulas

The Shandong (SD) and Liaodong (LD) Peninsulas are connected to the Asian mainland and the Korean Peninsula,respectively.Biodiversity of earthworm was systematically investigated in different habitats by digging in SD and LD in 2009.Earthworms were killed in 70% ethanol and then preserved in 95% ethanol for further research.A portion of the worms was transferred to 10% formalin for preservation as voucher specimens.An up-to-date inventory of the earthworms in SD and LD were presented based on this study.In total,13 species were collected in SD,mostly of the Megascolecidae (39% of total) and Lumbricidae (39% of total) families,while 16 species were sampled in LD,most of which belonged to the Lumbricidae (44% of total) and Megascolecidae (31% of total) families.Eisenia fetida (Savigny,1826),which was harvested intensely for the vermiculture industry,was also collected in free-living habitats.
