Aplicación de rasgos morfométricos tradicionales y geométricos para el análisis del complejo Achnanthidium minutissimum (Kützing) Czarnecki (Bacillariophyceae) en lagos de la cordillera oriental de Colombia

Abstract

The Achnanthidium minutissimum (Kützing) Czarnecki (Bacillariophyceae) complex is one of the most complex diatoms in terms of its taxonomy and nomenclatural history, due to the small size of the leaflets and intraspecific morphological differences related to the ecological response (Potapova and Hamilton, 2007). In order to study the morphological variation of the Achnanthidium minutissimum complex in lakes of the Eastern mountain range of Colombia, the analysis of traditional morphometry and geometric morphometry was used, applying this analysis to the five morphotypes identified and found within the Aquitaine Black Lagoons, Los PNN Pisba ducks. , Laguna Amarilla, Laguna Peña negra and Laguna los Pozos. These two methods allowed for a clearer and more precise differentiation for the identification of individuals.
