Iron-reducing bacteria from a copper-contaminated sediment were more tolerant of copper adsorbed to hydrous ferric oxide (HFO) than were pristine-sediment bacteria (Markwiese et al. 1998). Copper-tolerant bacteria were more efficient in reducing contaminated HFO, with greater potential for copper mobilization in aquatic sediments (Markwiese et al. 1998). 

Crayfish, Cambarus bartoni, copper-tolerant strain exposed to 19 (controls), 125, 250, or 500 gg/L for 4 weeks concentrations in controls (mg/kg DW) vs. all experimental groups (mg/kg DW) ... 

Increased tolerance to copper was observed in fathead minnows after prolonged exposure to sublethal concentrations, but tolerance was not sustained on removal to clean water. Copper tolerance in fathead minnows is attributed to increased production of metallothioneins (Benson and Birge 1985). Copper tolerance in rainbow trout seems dependent on changes in sodium transport and permeability (Lauren and McDonald 1987a). 

Mechanisms of copper tolerance or acclimatization to high doses of copper (ATSDR 1990)... 

Numerous and disparate copper criteria are proposed for protecting the health of agricultural crops, aquatic life, terrestrial invertebrates, poultry, laboratory white rats, and humans (Table 3.8) however, no copper criteria are now available for protection of avian and mammalian wildlife, and this needs to be rectified. Several of the proposed criteria do not adequately protect sensitive species of plants and animals and need to be reexamined. Other research areas that merit additional effort include biomarkers of early copper stress copper interactions with interrelated trace elements in cases of deficiency and excess copper status effects on disease resistance, cancer, mutagenicity, and birth defects mechanisms of copper tolerance or acclimatization and chemical speciation of copper, including measurement of flux rates of ionic copper from metallic copper.

Fig. 1. DE-52 elution profile of extracts of copper-tolerant Mimulus guttatus roots grown in jq Long Ashton Solution plus added metal ions, for 4 weeks (solutions changed every 4 days to maintain the metal concentration). The column was eluted with a linear gradient of 0 to 1 m KC1 in 10 itim HEPES, pH 6.5. Fractions were collected and measured for metal (- -) and conductivity (-0-)- Metal ions were added as sulphates. A, From roots grown in 4 xm copper. B, From roots grown in 2 p.M cadmium.
