“…The studied assemblages consisted of diatoms with various geographic distributions. Cosmopolitan species, such as: Humidophila contenta , Hantzschia amphioxys , Nitzschia brevissima , Pinnularia borealis ( Krammer and Lange-Bertalot 1986 ; Krammer 2000 ; Lange-Bertalot et al 2017 ) occurred together with species with a wide distribution in the tropics – Luticola distinguenda and L. intermedia ( Levkov et al 2013 ; Glushchenko et al 2017 ; Straube et al 2017 ; Da Silva-Lehmkuhl et al 2019 ). On the other hand, several of the noted species have not been reported from Africa so far or their occurrence in Africa has not been confirmed.…”

The knowledge about terrestrial diatom assemblages in southern Africa is rather limited, despite a long history of diatom research in this area. Terrestrial habitats are places of characteristic diatom floras, dominated by species resistant to desiccation which are able to thrive in conditions of limited water availability. The presented work expands the knowledge about these unique habitats. During the study on terrestrial moss-inhabiting diatoms from Western Cape Province (South Africa), four taxa with a unique set of valve features have been found and described herein as new species, based on light and scanning electron microscopy. These new species are: Luticola microcephala M. Rybak, Peszek & Kochman-Kędziora, sp. nov., Luticola asymmetrica M. Rybak, Kochman-Kędziora & Peszek, sp. nov., Luticola terrestris Kochman-Kędziora, M. Rybak & Peszek, sp. nov. and Microcostatus meridionalis Peszek, M. Rybak & Kochman-Kędziora, sp. nov. Algal community composition had low species richness (9–15 taxa per sample) and samples were dominated by: Humidophila contenta, Nitzschia brevissima and Eunotia aff. pseudominor. The three new Luticola species formed numerous populations, exceeding 10% of the share, whereas Microcostatus meridionalis reached 5.4%. Basic morphological data of associated diatom flora together with detailed micrographs are also provided.

Highlights of new, interesting, and emerging research findings on substratum-associated microbiota covered from a survey of 2019 literature from primarily freshwaters provide insight into research trends of interest to the Water Environment Federation and others interested in benthic, aquatic environments. Coverage of topics on bottom-associated or attached algae and cyanobacteria, though not comprehensive, includes new methods, taxa new-to-science, nutrient dynamics, auto-and heterotrophic interactions, grazers, bioassessment, herbicides and other pollutants, metal contaminants, and nuisance, and bloom-forming and harmful algae. Coverage of bacteria, also not comprehensive, focuses on the ecology of benthic biofilms and microbial communities, along with the ecology of microbes like Caulobacter crescentus, Rhodobacter, and other freshwater microbial species. Bacterial topics covered also include metagenomics and metatranscriptomics, toxins and pollutants, bacterial pathogens and bacteriophages, and bacterial physiology. Readers may use this literature review to learn about or renew their interest in the recent advances and discoveries regarding substratum-associated microbiota. © 2020 Water Environment Federation • Practitioner points • This review of literature from 2019 on substratum-associated microbiota presents highlights of findings on algae, cyanobacteria, and bacteria from primarily freshwaters. • Coverage of algae and cyanobacteria includes findings on new methods, taxa new to science, nutrient dynamics, auto-and heterotrophic interactions, grazers, bioassessment, herbicides and other pollutants, metal contaminants, and nuisance, bloomforming and harmful algae. • Coverage of bacteria includes findings on ecology of benthic biofilms and microbial communities, the ecology of microbes, metagenomics and metatranscriptomics, toxins and pollutants, bacterial pathogens and bacteriophages, and bacterial physiology. • Highlights of new, noteworthy and emerging topics build on those from 2018 and will be of relevance to the Water Environment Federation and others interested in benthic, aquatic environments

“…A number of taxa have been described and known to occur or cited in the tropics ( Hustedt, 1937–1939 ) or in high latitudes of the Southern Hemisphere ( Heiden & Kolbe, 1928 ; Giffen, 1966 ; Cholnoky, 1954 ). A change in our understanding of the distribution of Luticola taxa is occurred in the mid-1990s and a wealth of Luticola have been described as new to science from tropical rainforests of South America ( Metzeltin & Lange-Bertalot, 1998 ; Metzeltin & Lange-Bertalot, 2005 ; Bustos, Morales & Maidana, 2017 ; Straube, Tremarin & Ludwig, 2017 ; Da Silva-Lehmkuhl et al, 2019 ), in the Andes ( Rumrich, Lange-Bertalot & Rumrich, 2000 ; Simonato et al, 2020 ) and in South-East Asia (e.g., Glushchenko & Kulikovskiy, 2015 ; Glushchenko, Kulikovskyi & Kociolek, 2018 ). High diversity of Luticola also has been observed in Antarctica and Sub-Antarctic Islands ( Van de Vijver, Frenot & Beyens, 2002 ; Kopalová et al, 2011 ; Chattová et al, 2017 ; Kochman-Kedziora et al, 2020 ).…”

Background Rapa Nui (Easter Island = Isla de Pasqua) is of volcanic origin, best known for about 900 man-made stone statues known as moai. It is one of the most isolated inhabited islands on Earth and studies on the diatoms of Rapa Nui are very few. Methods Light (LM) and electron microscopic (SEM) observations of a single sample collected from Rapa Nui are presented. The samples (mix of soil and organic detritus) were collected from ground of cave entrance. Results The samples were characterized by low diatom diversity and strongly dominated by terrestrial (soil) forms. Among the taxa present in the material studied were cosmopolitan forms of the genera Humidophila, Nitzschia, Angusticopula, Orthoseira, Tryblionella and Luticola. Whereas most of taxa of the enumerated genera were identifiable, only one among four Luticola species distinguished in the samples studied was identified. This taxon was L. ectorii, a cosmopolitan species known previously from South America (Brazil) and Asia (China). The three remaining species could not be assigned to any established species. Therefore, based on external and internal morphological features from light and scanning electron microscopic analysis, we describe here three species new to science, including: L. georgzizkae, L. rapanuiensis and L. moaiorum. All three taxa new to science are compared to established Luticola species and their significance for the global distribution of the genus is discussed.
