“…Over 600 Cosmarium taxa were recorded for Brazil (Biolo & Bicudo 2018), and the genus was more intensively studied in the south region where numerous taxonomic studies revealed its presence in both phytoplankton and periphyton of reservoirs and rivers. Recent floristic studies recording the presence of Cosmarium in Brazil include States such as Paraná (Silva & Cecy 2004, Bortolini et al 2010, Felisberto & Rodrigues 2010, Biolo et al 2013, Menezes et al 2011, Carvalho et al 2015, Aquino et al 2016, Osório et al 2018, Rodrigues & Moresco 2021), São Paulo (Bicudo et al 2019, Felisberto & Rodrigues 2010, Bahia (Oliveira et al 2010, Oliveira et al 2011, Oliveira et al 2016, Ramos et al 2018, Ramos et al 2021, Goiás (Felisberto & Rodrigues 2004), Distrito Federal (Estrela et al 2011), Amazonas (Saturnino et al 2020), Sergipe (Burle et al 2020), Mato Grosso and Rio de Janeiro (Kanetsuna 2004). Furthermore, in the last 10 years five new species of Cosmarium were described based on Brazilian material: Cosmarium bahianum G.J.P.…”

Study aimed at identifying and recording smooth or finely punctate cell walled Cosmarium Corda species of the low Doce river region, Espírito Santo State, Brazil. Periphytic material was collected monthly during the period October 2018 to February 2020, except for October 2019. We identified 22 taxa and analyzed the environmental conditions (trophic state, pH and total iron) in which each taxon occurred. Our study recorded 21 new records of smooth cell walled Cosmarium for Espírito Santo State and one (Cosmarium trilobulatum var. tumidum Willi Krieger & Gerloff) for Brazil.

We analysed summer assemblages and the metacommunity structure of benthic microalgae and Cyanobacteria (BMC) living in pristine ecosystems in the Serranía de Cuenca (Central Spain), whose flora is not well-known. Our analyses were focused on both overall samples and some site subgroups (two large catchments, lotic vs lentic environments, plant vs mineral substrates). 379 taxa were recorded, with Diatoms, Chlorophytes and Cyanobacteria being the richest groups. The flora composition de-pended on conductivity and the percentage of forests in each sub-basin; even so, the composition was spatially homogeneous, reflecting the relatively low variability of the landscape. Taxonomic richness did not differ between inventory subgroups, but it was vulnerable to the somewhat higher values of low concentrations of nitrogen and phosphorus compounds. Two groups of BMC assemblages emerged in the territory: one of cosmopolitan Diatoms and Cyanobacteria, and another of Cyanobacteria, Diatoms and Chlorophytes associated with travertine. The structure of the metacommunity was governed by the contributions of space, catchment features and the local environment (chemical and biological); the relevance of biological factors, which are not usually analysed, was highlighted. Finally, we suggest the joint study of local ecology and metacommunity that is feasible with the many occurrence databases of many benthic organisms. Soon artificial intelligence and new taxonomic tools will allow faster and more comprehensive processing of the huge number of freshwater datasets already in existence, which will be a huge leap in ecological knowledge of benthic assemblages in the coming years.
