[Influence of the aquatic vegetation on the distribution of river mollusks on the Isle of Youth].
A study is made in 24 bodies of water in the Isle of Youth, which are considered the most representative, since they include dams, lagoons, seasonal ponds, and marshes. The indicators of abundance and coverage of mollusks and plants, respectively, are determined. It was found that the first varies according to the second. Some vital functions of mollusks (nutrition, oviposition, and support substratum) are closely related to vegetation. It was found that P. paludosa inhabits bodies of water with T. domingensis, a plant used for oviposition and that pulmonates, on the other hand, require floating wide-leaved vegetation such as N. grayanum and N. advena. P. paludosa does not have strict requirements as regards the plants used in feeding, while planorbids require soft-leaved plants such as Chara sp., Cabomba sp., Lemma sp., and U. mixta.
