Predicting temporary wetland plant community responses to changes in the hydroperiod

The expected changes on rainfall in the next decades may cause significant changes of the hydroperiod of temporary wetlands and, consequently, shifts on plant community distributions. Predicting plant community responses to changes in the hydroperiod is a key issue for conservation and management of temporary wetlands. We present a predictive distribution model for Arthrocnemum macrostachyum communities in the Doñana wetland (Southern Spain). Logistic regression was used to fit the model using the number of days of inundation and the mean water height as predictors. The internal validation of the model yielded good performance measures. The model was applied to a set of expected scenarios of changes in the hydroperiod to anticipate the most likely shifts in the distribution of Arthrocnemum macrostachyum communities.

Implications of climate change for rice farming in the Doñana wetland (SW Spain)

Climate change impacts are expected to affect rice farming and wetlands welfare in the Doñana protected Area, due to decreases in quantity and quality water supply and higher temperatures. The largest rice farming area is closely located to the Doñana wetlands in the Guadalquivir river basin estuary (South Western of Spain).
