Description

Over the last 20 years, loss of seagrass beds, often related with increased eutrophication, became a common problem worldwide. In the Mondego estuary (Portugal), eutrophication has triggered serious biological changes, which led to an overall increase in primary production and to a progressive replacement of seagrass Zostera noltii beds by coarser sediments and opportunistic macroalgae. http://www.sciencedirect.com/science/article/B6T8F-4B76GY1-1/1/2f9baf58e9f5bc8689beab357620d6a8
