Planktic diatoms, containing 26 columns headered using DwC term name (http://rs.tdwg.org/dwc/terms/): occurrenceID, organismID, basisOfRecord, scientificName, Kingdom, Phylum, Subphylum, Class, Subclass, Order, Family, Genus, specificEpithet, infraspecificEpithet, taxonRank, eventID, eventDate, samplingProtocol, decimalLatitude, decimalLongitude, geodeticDatum, countryCode, locality, references, sampleSizeValue, sampleSizeUnit.
Given the continuous changes in biological nomenclature, all scientific names published were checked and updated to the currently accepted nomenclature, following the Algaebase: Listing of World’s Algae (Guiry and Guiry, 2021).<br> Taxon specialists: Simona Musazzi, Martina Austoni, Aldo Marchetto.

| Descripción del área de estudio | Lake Maggiore is a large (212.5 km2), deep (370 m), oligotrophic, subalpine lake, located in Northern Italy at an altitude of 194 m a.s.l. |
| Descripción del diseño | Since 1974, CIPAIS has been promoting and contributing to the funding of research on the ecosystem evolution of Lakes Maggiore and Lugano, in relation to the environmental and climatic change. This activity carried out since 1978 in the face of five-year (or three-year from 2013) research programs ensured the systematicity for the acquisition of hydrological, meteorological and limnological data relating to lakes, their tributaries and hydrographic basins. |

Métodos de muestreo
Habitat type: sediment, stones, macrophytes and water column.
Sedimetary diatoms: Sediment cores were taken using a gravity corer 63.5 mm in diameter. Each core was cut lengthways, sliced into 1-cm sections, and dated using either ^137Cs or ^210Pb. Diatoms were cleaned following Battarbee et al. (2001) and mounted with Naphrax. For each sample, at least 500 valves were identified and enumerated.
Benthic diatoms: Samples were taken by scraping five stones (usually cobbles and small boulders) and macrophytes following a European wide standardized sampling protocol (Manuals ICP WATERS, 2010). Samples were taken from the littoral zone, in 8 stations identified along the perimeter of the lake and in the Bolle di Magadino wetland, an area which is in direct hydraulic connection with the lake, as reported in Boggero et al (2022). Digestion followed standard procedures. For each sample, at least 400 valves were identified and enumerated.
Pelagic diatoms: Samples for phytoplankton were all collected at a central sampling site, corresponding to the point of lake’s maximum depth (370 m). Samples were always collected with an integrating bottle in the 0–20-m water layer, corresponding to the euphotic layer in Lake Maggiore. Counting followed CEN (2004) and Lund (1958).
| Área de Estudio | the dataset contains information on 4124 occurrences for 293 taxa. The occurrences were recorded during the years 1984-2021 The study area is 212.5 km^2. |
|---|---|
| Control de Calidad | Quality control for geographic data: coordinates were collected by GPS during sampling and verified on topographic maps. Quality control for taxonomic data: before publication of the data set, algal taxon spelling andauthorship were verified and updated using Algaebase: Listing of World’s Algae (Guiry and Guiry, 2021). |
Descripción de la metodología paso a paso:
- The dataset was built based on 2 scientific papers and technical reports published in the frame of the research programs funded by the International Commission for the Protection of Swiss-Italian Waters (CIPAIS). Sampling procedures followed standardized sampling protocols (CEN, 2004; Manuals ICP WATERS, 2010). Algal taxon spelling and authorship were verified and uploaded using Algabase: Listing of World’s Algae (Guiry and Guiry, 2021). Diatom synonyms were merged when present. Data were gathered in a csv file reporting taxon name and additional informations about taxonomy, origin and habitat, following DwC term names (http://rs.tdwg.org/dwc/terms/).
