Determining the Ecological Effects of Oil Pollution in Marine Ecosystems toxic to many organisms, current knowledge does not allow precise estimation of ecological damage resulting from oil pollution.

The Effects of Chemical Stress on Aquatic Species Composition and Community Structurecosystems are particularly responsive to chemical stress, because pollutants tend to be well-distributed throughout zones of active mixing, and because communities tend to be dominated by motile, short-lived species with high reproductive rates. Response to chemical stress often involves rapid chang作者: 使長胖 時間: 2025-3-22 12:57
