Tropical South American diatom database


This repository contains the code and data of contemporary (1980s - 2017) diatom datasets of tropical South America (TSADB). The database includes diatom (unicelular siliceous algae) data and associated environmental variables of waterbody sites (streams, wetlands, lakes), covering an altitudinal gradient from 220 to 5,070 m a.s.l. between 8°N–30°S and 58–79°W. Datasets are available as Excel Data Tables on Dryad and Zenodo as R files, while here the aim is to provide a shiny app to interactively visualize and explore the database in R for promoting biodiversity, biogeographic and paleolimnological studies in tropical South America.
