Erpobdella octoculata

Freshwater leech, Erpobdella octoculata, adults, Upstream (18 pg Zn/L) from zinc-polluted 116... [Pg.661]

Populations of freshwater oligochaetes and leeches were reduced in numbers of individuals and numbers of taxa in mine tailing effluents containing 146 to 213 pg Zn/L or sediments containing >20 g Zn/kg DW (Willis 1985b). Leeches (Erpobdella octoculata) experienced a reduction in density and reproductive capacity in streams containing 25 to 310 pg Zn/L from mine wastes and did not avoid these harmful concentrations (Willis 1989). [Pg.702]

Among freshwater leeches, the Old-World Erpobdella octoculata feeds on prey such as Tubifex spp., Chironomus spp., and Asellus aquaticus. Living and freshly killed larvae of Chironomus sp., Tubifex sp., and A. aquaticus attract these leeches. Amino acids such as histidine and glutamic acid are the active stimuli (Kreuter et al. 2008). [Pg.142]
