Experimental Manipulation of Model Ecosystems
Ecosystems have been described as the “functional units of the landscape” (Odum, 1971), where organisms interact with their physical-chemical environment and with other organisms. For limnologists, lakes, ponds, streams, and rivers and their associated drainage basins represent the ecosystems of interest. However, these ecosystems are large and complex, and thus it is difficult to decipher the various interactions that occur within them.
