Joanne Burkholder and Larry Crowd- 

 er speculate that an overabundance of 

 nutrients such as nitrogen and phos- 

 phorus causes excessive amounts of 

 algae to grow on the plants. The algae 

 shades the grasses from the sun and 

 photosynthesis is slowed. Eventually 

 the grasses die. The researchers also will 

 test the correlations between small 

 grazing marine animals and the algae.
