| short-term physiological responses to a severe acid stress in three macroinvertebrate species: a comparative study. | the present study focuses on the sensitivity among freshwater invertebrate species to acidic stress. three common macroinvertebrate species in the vosges mountains (north-eastern france), gammarus fossarum (amphipoda), hydropsyche pellucidula (trichoptera) and dinocras cephalotes (plecoptera) were exposed for 24, 72 and 120 h to natural acidified water (ph=4.73+/-0.08, [ca2+]=39.1+/-0.6 micromol l(-1), [al(tot)]=28.4+/-1 micromol l(-1)). short-term exposure to acid stress caused significant decr ... | 2006 | 16303164 |
