Lemna and the Lake Eutophication.

Lemna commonly known as Duck weed or Duck meat is a genus with eight species. It is a minute aquatic plant belonging to family Lemnaceae, which includes Spirodela, Wolffia and Wolffiella other than Lemna. Lemna is an important source of food for aquatic fauna but becomes a havoc when its population explodes due to eutrophication. Eutrophication pollutes the aquatic environment and hence is responsible for the death of the aquatic fauna. In order to overcome the menace of this problem it is necessary to interrupt the life cycles of aquatic plants. Scientists have been trying to do this in a number of eutropic lakes but the problem immediately demands identifying the aquatic plants and also studying their characteristics and interpreting the relationships between the different taxa. The species in the genus Lemna although are similar in general form but have certain distinct morphological differences in terms of some distinct or uniquely derived characters. Genera like Wolffia are also difficult to separate from Lemna. Some species possess fruiting fronds that help them to propagate more readily while others have persistent roots that don’t wither soon, so such species are rather difficult to get rid of. An effort has been made to differentiate species within Lemna and on the basis of certain distinct ecological, morphological and genetic traits and it is found that they are separated by distinct autapomorphies. Also, the role played by Lemna in enhancing eutrophication of lakes has been studied.
