Eutrophication: top-down or bottom-up control?

Start Date: 

22 Jun 2011 (All day)

Nutrient enrichment has been shown to have potentially dramatic effects on aquatic and wetland systems. Shifts from a state with good water quality and high biodiversity to states with anoxia, fish kills, and loss of species have been found worldwide. 
The mechanisms behind the phenomena are becoming more clear. The symposium will highlight such mechanisms, emphasizing the role of bottom-up control (nutrient cycling in the system) as well as top-down control (food-web relations).
