| antioxidant response to natural organic matter (nom) exposure in three baikalean amphipod species from contrasting habitats. | the aim of the present work is to comparatively evaluate the oxidative stress response on exposure to natural organic matter (nom) in three amphipod (crustacea, amphipoda) species from different taxonomic groups and different habitats of lake baikal. endemic species from lake baikal were used: the shallow-water dwelling gmelinoides fasciatus (dyb.), pallasea cancelloides (gerstf.), and the deep-layer inhabitant ommatogammarus flavus (dyb.). three key enzymes, catalase (cat), peroxidase (pod), an ... | 2006 | 16914340 |
