Limnological comparison of two peridunar ponds in the Doñana National Park (Spain)

The ponds Santa Olalla and Dulce belong to the peridune pond system on the E—W coastline of the Doñana National Park. The water that fills these ponds originates in the groundwater tables of the dunar system, and these ponds also contain rainwater (run-off and drainage). Despite the fact that they...
