Abstract |
The general ecology of Eleocharis acicularis (L.) R. and S. was studied with special emphasis placed on its relation to acid polluted streams. Distribution and vigor appear to be related to the pH and P levels of the water and substrate. In laboratory experiments, growth was optimal in the pH range of 3.6 to 5.0 and inversely proportional to P concentration. Other mineral factors appear to be unrelated to E. acicularis distribution. Reciprocal transplants and microscopic examination of the culm confirmed the identity of the sterile-aquatic form and the fertile-terrestrial form. The abundance of aufwuchs and certain insect larvae point to the importance of E. acicularis in providing suitable substrate and shelter for other organisms. |
