Diatom communities monitoring in temporary rivers of Sant Llorenc del Munt i l'Obac Natural Park (Catalonia, Spain)

This dataset includes 30 sites with diatom counts and associated water chemistry parameters from temporary rivers in Sant Llorenc del Munt i l'Obac Natural Park (Catalonia, Spain). Diatom data represents epilythic samples collected at 4-5 different points of each of the seven rivers (Vall d'Horta, Rellinars, Santa Creu, Sanana, Talamanca, and Mura) during the seasons of 2019. These streams showed a wide degree of flow permanence, which allowed the recording of different typical phases of temporary rivers (moments of maximum water flow, cessation, disconnection, and drought). The dataset has been formatted following the standards of the Tropical South American Diatom Database (https://zenodo.org/records/5721364)—a database constituent of Neotoma (www.neotomadb.org), a global community-curated database by regional experts for multiple types of paleoecological data—and as part of the project "DiatomS mEEt Databases: resources and practices to enable large-scale ecological research (SEED)" funded by the International Society for Diatom Research (https://isdr.org/early-career-networking-award/).
