MORFOMETRÍA GEOMÉTRICA DE Brachionus plicatilis PRESENTE EN LA LAGUNA SALINA TEMPORAL “SALINA RICA”, ESTADO ZULIA-VENEZUELA.

The determination of the form of Brachionus plicatilis has generated controversy because a complex of 14 species with great fenotipic plasticity is considered at least. It is by that it was made a Biometric analysis and a Geometric Morfometric (GM) analysis to individuals of a unknown population, were collected in a lagoon hypersalt mine located in the city of Maracaibo. The Biometric analysis was based on measures of the anterodorsales thorns, wide and long of the loric. In Geometric Morfometric analysis 17 Landmarks were considered. These two studies were related to the biotic and abiotic variables of the lagoon, to find because was a morfometric variability. The result of the Biometry threw a change of significant size (Wilks’ λ= 0,13; F= 4,17; p<0,0001) the averages of the measurement of the length of the loric was of 123.33 µm and to the wide maximum of the loric was of 91.28 µm. For the GM change of general form was not obtained significants (Wilks λ = 1,0, F= 0,0, df= 430, p= 1,00).
