Abstract
Aquatic ecosystems have many real problems due to anthropogenic impacts. Chemical pollution is one contributing factor to these problems. Population dynamics of the organisms are controlled by complex combinations of biotic interaction and abiotic environmental factors. Vulnerability to the toxic chemicals differs between each species, so the chemicals should induce different community structures. Moreover, the chemicals not only affect the individual survival or the reproduction rate, but also disturb the prey-predator interactions at very low concentrations. Here, we will introduce the recent studies focusing on the impacts of anthropogenic chemicals on
aquatic food webs.
