| the use of two species of crayfish as environmental quality sentinels: the relationship between heavy metal content, cell and tissue biomarkers and physico-chemical characteristics of the environment. | in systems as heavily disturbed as rivers, the use of biological sentinels is a most interesting way of obtaining continuous assessment of environmental quality. this study seeks to establish the value of such sentinels of two species of crayfish: the native crayfish (austropotamobius pallipes, lereboullet 1858) and an introduced species, signal crayfish (pacifastacus leniusculus, dana 1852), by comparing the habitat quality (water and sediments) and heavy metal contents in crayfish with the deg ... | 2000 | 10803551 |
