“…Since maintenance of a tolerance mechanism may be energetically expensive, `costs of tolerance' have frequently been suggested as a possible consequence of being tolerant (Holloway et al, 1990 ;Klerks & Levinton, 1989 ;Posthuma & Van Straalen, 1993 ;Wilson, 1988) . As in other cases of lowered fitness for tolerant individuals cultured in clean environments (Cook et al, 1972 ;Cox & Hutchinson, 1981 ;Hickey & McNeilly, 1975 ;Weis & Weis, 1989), the lowered larval growth rate of the iron tolerant population Westerloo could also indicate such costs .…”

Key words : Chironomus riparius, metal tolerance, Cd, Zn, Fe Abstract Metal tolerance in Chironomus riparius (Diptera) populations from contaminated streams was studied by comparing the effects of cadmium, zinc and iron on first generation laboratory reared midges . First instar larvae were exposed for four days, after which surviving larvae were counted and their length measured . Larvae from two highly polluted sites, kept under control conditions, grew substantially slower than those from other populations . All populations showed the same growth responses to increased zinc concentrations, but differences were found in the responses to both cadmium and iron . Since population differentiation was demonstrated in first generation laboratory animals, it is suggested that the differences between populations of C . riparius have a genetic basis .

“…However, in experiments on cadmium-adapted chironomids cultured in the absence of cadmium no indications were found for a lowered age of reproduction (Postma et al 1995b). On the other hand, results demonstrated a reduced fitness under clean conditions, which is commonly explained as costs of being tolerant (Cook et al 1972;Cox & Hutchinson 1981;Holloway et al 1990). Both larval mortality and larval development time were shown to be increased compared to reference populations (Rl & R2), when cadmium-tolerant midges (PI & P2) were cultured in a clean environment (figure 1.2).…”

“…There are suggestions that geographical variations in the annual cyclic levels of pollutants put selection pressure on organisms to overcome a range of negative effects of pollutants (Holloway et al 1990, Forbes and Calow 1997, Johansson et al 2001). There is not any extensivestudy exploring level of adaptation of the same amphibian species to varying levels of ammonium-nitrate.…”
