Eutrophication, Fisheries, and Consumer-Resource Dynamics In Marine Pelagic Ecosystems

摘要

Anthropogenic nutrient enrichment and fishing influence marine ecosystems worldwide by altering resource availability and food-web structure. Meta- analyses of 47 marine mesocosm experiments manipulating nutrients and consumers, and of time series data of nutrients, plankton, and fishes from 20 natural marine systems, revealed that nutrients generally enhance phytoplank ton biomass and carnivores depress herbivore biomass.
