Description
This dataset contains the digitized treatments in Plazi based on the original journal article Ruwer, Daiane Trevisan, Rodrigues, Liliana (2021): Sediment diatoms from Upper Paraná River floodplAiN lAKeS: New recordS. Iheringia, Série Botânica (e 2021012) 76: 1-16, DOI: 10.21826/2446-82312021v76e2021012, URL: dx.doi.org/10.21826/2446-82312021v76e2021012 ABSTRACT – Considering changes in biodiversity over large time scales, the use of sediments to access knowledge about current and past diversity has recently been highlighted as an emerging field for biodiversity science.Therefore, this work aimed to use lake sediments to perform a taxonomic survey of abundant diatoms from two lakes sediments from the Upper Paraná River floodplain and contributes to new species registrations.
For diatom flora analysis were selected sediment samples from lakes. The diatoms with relative abundance ≥ 2% in at least one sediment sample were analyzed and identified under light microscopy. The study resulted in the identification of 47 taxa, including 40 at the specific level and seven possible new taxa.Among the taxa identified, 12 taxa (27%) of these had never before been documented in the Upper Paraná River floodplain.

Considerando as mudanças na biodiversidade em uma longa escala temporal, o uso de sedimentos para acessar o conhecimento sobre a diversidade atual e passada foi recentemente destacado como um campo emergente para a ciência da biodiversidade.
Portanto, este trabalho teve como objetivo utilizar amostras de sedimentos de lagos para realizar um levantamento taxonômico de diatomáceas abundantes de sedimentos de dois lagos da planície de inundação do Alto Rio Paraná e contribuir com o registro de novas espécies. Para análise da flora de diatomáceas amostras de sedimentos dos lagos foram selecionadas. As diatomáceas com abundância relativa ≥ 2%, em pelo menos uma amostra de sedimento, foram analisadas e identificadas sob microscopia óptica.
O estudo resultou na identificação de 47 táxons, incluindo 40 no nível específico e sete possíveis novos táxons. Entre os táxons identificados, 12 (27%) deles nunca haviam sido documentados na planície de inundação do Alto Rio Paraná. Palavras-chave: Bacillariophyta, levantamento, rio Paraná, sedimento, taxonomia.
