BLANCO, Marcela Adriana. Morphometric characters of Difflugia corona (Testacea, Difflugidae) in lentic environments of Chaco, Argentina. Iheringia, Sér. Zool. [online]. 2001, n.91, pp.79-83. ISSN 0073-4721.

Morphometric characters of two populations of Difflugia corona Wallich, 1864 collected in two climatic stations (Spring, Autumn) in lentic environments of Chaco Province, Argentina, are studied. In the first climatic station it was registered specimens of bigger size; in the second, the size of the individuals was very below the minimum values registered. It is suggested a possible relationship between the size of the organisms and the availability of the inhabitable vegetable substratum.

Keywords : Difflugia; morphometric characters; Chaco; Argentina.
