Rio Camarones Oraganic Matter input

I study decomposition in aquatic systems, and most research in this area focuses on leaves as the major source of outside input of organic matter into these systems.  However, in tropical systems, flower and fruit material can make up a substantial portion of OM input in streams, as discuss in Tropical Steam Ecology and evidenced in this photograph.

While sampling, flower parts rained into Rio Camarones in Sirena, completely covering the surface.  And, just like in Ohio, the stream was filled with abundant crustaceans, probably acting as shredders!
