Alternative states in shallow lakes


This project results from the collaboration between IH-Cantabria, UDELAR University (Uruguay), the Universidade Federal do Rio de Janeiro (Brazil) and the National Institute for Space Research (INPE, Brazil) to investigate the mechanisms that control dynamic alternative states of shallow lakes belonging to the Cuiabá river floodplain in the Pantanal (Brazil).

The shallow lakes of the Pantanal have a spatial and temporal pattern of complex alternative states, determined in part by the connectivity to other waterways. The tributary water quality, especially turbidity plays a key role in shaping these ecosystems. In this project we are investigating the relationship between flood pulses in the Cuiabá River and morphometric variability, water quality and trophic structure of three shallow lakes using a combination of field surveys and satellite imagery that can reconstruct data sets for over 20 years.
