Plants show rapid adaptation towards resistance against heavy metals. In contrast, tests examining the local adaptation of insect herbivores to heavy metal pollution are lacking. Here we test whether the autumnal moth Epirrita autumnata, living in a heavy metal contaminated area, shows local adaptation in the growth rate and immune function. We gathered male moths from control and polluted area...
Estuaries are well known for their potential in removing metal from fresh water to provide micro-nutrients to aquatic life. In the present investigation, we have tried to bring out the metal removal potential of estuaries during accidental spills. For this purpose artificial river water containing high concentration of Mn, Cu, Zn, Ni and Pb were mixed with sea water at different salinity regime...
