An invasive mussel is in trouble: How do glyphosate, 2,4-D and its mixture affect Limnoperna fortunei's survival?

Contamination and biological invasions are important factors that alter the functioning of freshwater systems. We carried out two experiments involving daily measurements of dissolved oxygen (DO) and Limnoperna fortunei mortality: 1) the impact of DO on mussel survival mediated by glyphosate, 2,4-D and their mixture was analysed in a 22-day indoor experiment (IE) under controlled conditions using microcosms with L. fortunei, with and without air supply; and 2) the effect of each herbicide and their mixture on mussel accumulated mortality was compared in a 18-day outdoor experiment (OE) using mesocosms without air supply, with and without L.
