Years of Mesocosm Experiments
Predicted to be ready in 2020
Description of Facility

The mesocosms are located in the shore of the Upper River Paraná in Brazil. They are installed in a field station with boats, lodges for ca. 20 persons, kitchen all other facilities (e.g., aquaria, laboratories to work the samples etc.).

Controlled Parameters

Previous experiments using these facilities have controlled the presence of invasive species, habitat complexity, water chemistry and water level among others, but it is not possible to control temperature in the mesocosms.

Research Topics

Effects of invasive species on native communities, mechanisms that make ecosystems to resist to invasions, top-down and bottom up mechanisms in freshwater food webs, among others.

Facility location(s)
Primary interests

Ecology of invasive species, food webs.

Specialist areas

Ecology and systematic of phytoplankton, zooplankton, macrophytes, invertebrates and fish.


Equipment to measure basic water parameters (pH, turbidity, oxygen and temperature). Possibility to measure water nutrients.


Lodge for 20 persons + four individual chalet enough for two persons each.
