The phytoplankton of Lagunas de Ruidera (Natural Park, Ciudad Real, Spain)
The Lagunas de Ruidera Natural Park is a humid zone classified a's of national importance, located in the alto de Guadiana valley, Ciudad Real. Me Park is composed of 15 lagoons separated by travertine barriers, which end in the Peñarroya reservoir This work shows the first published data on bi...
