Dieta de Pseudocorynopoma doriae (Characiformes: Characidae) en el arroyo La Choza, Buenos Aires, Argentina
In this paper the objective is to characterize the Pseudocorynopoma doriae diet of the La Choza stream, assessing the relative importance of the contribution of the terrestrial environment to it and compare it with mesopotamian lotic environments. In all environments studied this species presented an invertivorous feeding. In the case of La Choza stream, comparison of diet between sampling dates showed a low degree of similarity, nevertheless the food items were all related to the surface film of water. Latter also is found in mesopotamian streams. When comparing the results of the percentage composition of the diet of P. doriae, it has shown that in mesopotamian environments diet is dominated by allochthonous insects while in the case of La Choza, dominance is shared with autochthonous items.

En este trabajo, el objetivo es caracterizar la dieta Pseudocorynopoma doriae del arroyo La Choza, evaluando la importancia relativa de la contribución del medio ambiente terrestre a este y compararlo con los entornos lóticos mesopotámicos. En todos los ambientes estudiados esta especie presentó una alimentación invertívora. En el caso del arroyo La Choza, la comparación de la dieta entre las fechas de muestreo mostró un bajo grado de similitud, sin embargo, todos los alimentos estaban relacionados con la película superficial del agua. Este último también se encuentra en los arroyos mesopotámicos. Al comparar los resultados de la composición porcentual de la dieta de P. doriae, se ha demostrado que en los ambientes mesopotámicos la dieta está dominada por insectos alóctonos, mientras que, en el caso de La Choza, la dominancia se comparte con elementos autóctonos.
