“…On the global level, it is a widely distributed taxon, known from Europe (i.e. Berlin, Germany, see Geissler and Kies 2003 ), Russia ( Genkal et al 2020 ), Asia (Iran), North America (Canada, USA), Africa (Egypt, RSA); Adriatic, Aral, Azov, Baltic, Barents, Black, Caspian, Kara, Mediterranean, North and Red Seas, and throughout North America ( Stoermer and Julius 2003 ). It is also very common in Brazilian waters ( Stoermer and Julius 2003 ; Tremarin et al 2009 ; Nardelli et al 2016 ).…”

“… Aulacoseira islandica is most often occurring as planktonic or tychoplanktonic taxon in water bodies of different types in high latitude or high altitude oligotrophic to mesotrophic large waters ( Houk et al 2010 ; Stoermer and Julius 2013; Genkal et al 2020 ). Sometimes this species may even cause a spring bloom (Stoermer and Julius 2013).…”

The diversity of centric diatoms is documented for the transitional zone of the lower part of the Southern Bug River (Ukraine) just before entering the Dnipro-Bug Estuary and compared to earlier results from the upstream sampling sites of the same river system. Benthic samples of the following sites were investigated: north of Mykolaiv City (approximately 5 km), in Mykolaiv City (near Varvarivskyi Bridge), and 5 km south of the city. Twenty-four centric diatom taxa belonging to 11 genera were identified, analysed, and documented by scanning electron microscopy (SEM) and light microscopy (LM). Among them, Aulacoseira nivalis is the first report for Ukraine, A. islandica and is the first confirmed record for the studied area since the 1930s. The maximum number of centric diatom taxa found in one station was 21, the minimum 10. Melosira subglobosa was the most common (documented in 57–80% of sites with centric diatoms) and abundant species 7.3–15.7% in relative abundance to all diatom taxa. The discovered diversity of taxa and its comparison with previous results is discussed with regard to the relevance of estuary zones in the research of diatoms.

Paleolimnological responses of Ecuadorian páramo lakes to local and regional stressors over the last two millennia

et al. 2023

Increasing surface air temperatures and human influences (e.g., agriculture, grazing, mining, urbanization, tourism) are altering lakes on the Andean páramo of South America, as illustrated by changes in diatom species composition in sediment cores from the region that span the last ~150 years. Previous studies were limited by their relatively short temporal scales and limited spatial coverage. We analyzed sediment cores from the northern (Laguna Piñan) and southern (Laguna Fondococha) Andean páramos of Ecuador. The deposits span the last two millennia and provide a longer-term perspective on past changes in lake ecological and geochemical dynamics.Both lakes show shifts in dominant diatoms through time. Dominant diatom taxa in Fondococha shifted between two Aulacoseira species, and there was a change in the planktic to benthic ratio, a proxy for open-water versus shallow-water habitats. Both changes are interpreted as evidence of fluctuating lake level. The inferred lake-level changes are corroborated by stratigraphic variations in the concentration of Ti, an erosional proxy, indicating changes in clastic input as a function of wetter or drier conditions. Piñan shows a directional shift in the diatom assemblage over the period of the record, from benthic diatoms tolerant of high dissolved organic carbon (DOC), low pH, and low nutrients, to an assemblage characteristic of lower DOC, higher pH, higher nutrients, and higher lake levels. Shifts in Piñan's diatoms are correlated with tephra layers in the sediment, suggesting that local volcanic ash deposition may have altered both the catchment and lake geochemistry. This is supported by relatively higher δ 13 C values in organic matter associated with tephra layers, which become more negative up-section. Our data suggest that remote lakes in spatially heterogenous montane regions are sentinels of environmental change, and the records from Piñan and Fondococha provide insights into Andean ecosystem responses to past environmental perturbations.
