Salado basin laboratory
Our work focuses on studying the spatial-temporal dynamics of different communities (phytoplankton, zooplankton and fish) of the province’s watersheds of Buenos Aires, especially that of the Salado River and the bodies of water associated with the same; evaluating, among other things, how different types of stressors, whether they are natural (e.g., predation, floods, or droughts) or anthropic (e.g., land uses, pollutants, dredging works), can modify them.
WHAT TASKS DO WE PERFORM?
We are also interested in analyzing the responsiveness of these assemblies of species and their resilience; studying water connectivity between different habitats from a comprehensive perspective, which includes the social perspective in relation to tourism, environmental education, and the sustainable use of natural resources common.
LINES OF RESEARCH
We are currently working on three main lines:
- Evaluate hydrological connectivity and the role of systems associated with the main course of the river, such as overflow lagoons or wetlands, and its effects on the structure and dynamics of the assemblage of species in the plankton and fish.
- Know the assemblage of plankton (plant and zoo) and environmental factors that modulate it, in Pampas lagoons and particular environments such as are the cavas (environmental liabilities), in relation to their use as sites to develop multipurpose aquaculture projects of native fish, from a socio-ecological and transdisciplinary perspective.
- Evaluate the use of the fishery resource as a sporting activity, and its social and economic implications in environments of the Salado, Samborombón and del Plata.
CAMPAIGN AND LABORATORY ACTIVITIES
Video filmed over the Romero Bridge (near San Miguel del Monte) showing part of the Las Flores System, with the Salado River itself and the Las Flores Grande lagoon. It can be seen that the river carried a lot of water, with a speed of flow high.
Fig. 1: Daphnia spinulata - Fig. 2: Experiments conducted with the cladoceran Daphnia magna, to study how plastic degradation products (BPA) and changes in temperature (constant or fluctuating heat waves) affect some traits of their life history (growth, reproduction and molting). - Fig. 3: Notholca sp. This organism is part of the zooplankton, we usually find it in the river Salado and other environments and one of its characteristics is that it is an indicator of cold water.
