The diatom flora in temporary ponds of Doñana National Park (southwest Spain): five new taxa

Researchers have identified five new diatom taxa in the temporary ponds of Doñana National Park, southwest Spain. These microscopic algae, described as Eunotia vozmedianoi, Planothidium lacustre, Halamphora tharsis, Gomphonema undulans, and Pinnularia acidophila var. baetica, were discovered during a 2010 biological survey of shallow ponds within this UNESCO World Heritage Site. Using light and scanning electron microscopy, the study revealed these taxa as novel to science, contributing to the understanding of diatom endemism in the region. The findings suggest that endemism may be more widespread among diatoms than previously thought, with implications for ecological and biogeographical studies.
