Study locations, site-specific information on water temperature and selected species. The current water temperature range for Brazil was determined using water temperature data for the Rio Negro provided by INPA (personal communication). In Uganda, water temperature data for Lake Victoria and the Sio River were provided by the National Fisheries Resources Research Institute and used to determine the range. Lastly, the current water temperature range reported for Cambodia was based on data for the Tonle Sap Lake provided by Cambodia’s Inland Fisheries Research and Development Institute. The control temperature for thermal acclimation was defined as the average maximum water temperature observed at each location, whereas current water temperature range corresponds to the range of ambient water temperature encountered in the natural habitat of the species.
