Free-living protists play important roles in biogeochemical cycling and food-web chains in both aquatic and terrestrial environments. However, their biogeography and spatial distribution remain poorly resolved. Here, we used silica-scaled chrysophytes to determine the most important climatic, historical, and environmental variables that explain biodiversity patterns across different geographical scales; the continental scale was represented by 473 European sites (gradient of 3,800 km), the local scale comprised 69 Aquitanien (France) sites (gradient of 186 km). Generalized Additive Models were used to evaluate the relationship between species richness and explanatory variables. Partition of community variance into fractions, explained separately by local environment, history, and climate helped us to track the main drives of community composition. While species richness was evenly influenced by all factors at the European scale and predominantly by environment (pH) at the local scale, the main factor shaping community composition was climate at both scales and history (geographical distance) at the European scale. Our results showed that silica-scaled chrysophytes respond strongly to climate-related variables at a broad geographical scale. Our work highlights the effect of climate on protist biogeographic structuring and suggests that climate-related variables may represent one of the main drivers of protist distribution, similarly as in macroorganisms.

“…However, their estimated species number is continuously changing year by year due to the newly described species from both recent and fossil samples (e.g. Barreto, 2001;Wujek et al, 2003;Kim & Soon Kim, 2008;Němcová et al, 2011;Němcová & Kreidlova, 2013;Gusev et al, 2016;Gusev & Siver, 2017;Siver, 2018;Kapustin & Gusev, 2019;Němcová et al, 2022).…”

Silica-scaled chrysophytes are a unique group of protists representing a major component of numerous aquatic habitats where they can significantly contribute to human well-being in many ways. In the present review, altogether 14 ecosystem services provided by silica-scaled chrysophytes were identified highlighting their importance and roles in aquatic ecosystems. The most important supporting services are related to primary production, nutrient- and biogeochemical cycling, as well as sediment formation. Additionally, they are involved in the regulation of climate, maintenance of air quality, biological control and water purification processes (as regulating services). The most relevant provisioning services include their usefulness in environmental monitoring (paleolimnology, ecological status assessment and climate modelling), production of biochemicals and provision of genetic resources. Cultural services are associated with aesthetic values, inspiration source and knowledge system as well. Although silica-scaled chrysophytes are one of the least studied groups of algae, here they are shown to provide important benefits and to have many further powerful opportunities for humans, thus their detailed research in the future is emphasised as an important key for human well-being.
