Efectos de las actividades antrópicas sobre parámetros metabólicos en un bivalvo invasor y otro nativo en el tramo inferior del río Paraná

The relationship between anthropogenic pollution, geochemistry and natural dynamics of freshwater ecosystems determine the spatial temporal patterns water quality. Human activities introduction exotic species are main causes decrease in biological diversity. spread invasive bivalve Corbicula fluminea endangers presence native Diplodon delodontus. Through oxidative stress indicators, it is possible to quantify response organisms changes physical-chemical, and/or variables. Therefore, objective was interpret effect physical-chemical variables, contaminants xenobiotics on metabolic responses C. D. delodontus Paraná de las Palmas river. Randomly, we established a sampling point collect individuals (60 10 bivalve) for assembly cages by placement site September 2018. In June 2019, five each were extracted at random. water, parameters metals measured, organs both species, protein concentration, glycogen, lipid damage, reduced glutathione content, enzymatic activity catalase glutathione-S-transferase. general, metal increased significantly from September. Metals exceeded quality guideline levels protection aquatic life. relation these differed gills digestive gland showed higher faster than study through measurement multiple variables useful tool characterize environment, with application prospects monitoring conservation studies.
