Escalating nitrogen (N) deposition has profound effects on terrestrial ecosystems; however, the mechanisms underlying soil protist community responses in cold-temperate regions remain poorly understood. This study investigated the effects of long-ter...
Anthropogenic stresses are intensively affecting the structure and function of microbial communities in coastal ecosystems. Despite being essential components of coastal ecosystems, the environmental influences and assembly processes of protist commu...
Dry, harsh, nutrient-limited environments such as the McMurdo Dry Valleys, Antarctica, may be particularly susceptible to changes in nutrient availability, demonstrating strong deterministic community assembly processes shaping communities within an...
Haptophytes (Hacrobia: Haptophyta), which can perform phototrophic, phagotrophic, or mixotrophic nutritional modes, are critical for element cycling in a variety of aquatic ecosystems. However, their diversity, particularly in the changing Arctic Oce...
Ornamental fountains in the Alhambra and Generalife (Granada, Spain) constitute complex socio-ecological systems where water, stone, and biological communities interact, making them highly vulnerable to biodeterioration caused by phototrophic microor...
Lampenflora, a complex phototrophic community that develops near artificial light in show caves, is recognized as a major concern for cave management and its regular monitoring has become necessity. For the purpose of this work, the monitoring was pe...
During the past decades, tremendous advances have been made in the possibilities to study the diversity of microbial communities in the environment. The development of methods to study these communities on the basis of 16S rRNA gene sequences analysi...
Oligotrophic marine environments are ecological funnels in marine ecosystems and are essential for maintaining the health and balance of the entire marine ecosystem. Bacterial communities are one of the most important biological populations, which ca...
Kuibyshev Reservoir, the largest in the Volga basin, is poorly covered by modern molecular studies. The results of a metabarcoding study of pro- and eukaryotic microbial plankton in its lower section during the summer period are presented. Bacteriopl...
Along the shoreline of the White Sea, due to the post-glacial uplift of the coast, some water bodies with stable stratification have been formed. They have been classified as meromictic as they are at different stages of isolation from the Sea. As se...
The structure and diversity of microbial communities developing in the combined gradient of temperature (44–19 °C), as well as concentration of oxygen (0–10 mg/L) and hydrogen sulfide (33–0.7 mg/L), were studied in the thermal s...
Biological soil crusts (biocrusts) accommodate diverse communities of phototrophic and heterotrophic microorganisms. Heterotrophic protists have critical roles in the microbial food webs of soils, with Cercozoa and Endomyxa often being dominant group...
For the first time, we investigated species composition, phytoplankton community structure, and hydrochemical parameters in the artificial cooling reservoir of a major thermal power plant (TPP) in northeastern Europe located in the Pechora River basi...
Microbial communities are central components of river ecosystems. They are involved in the transportation and transformation of certain pollutants, including nutrients discharged into surface water. Knowledge of microbial community structures is vita...
We analyzed riverbed microbiota structure, gene expression, and fatty acid production across several sites along Little Miami River in Ohio, United States. The sites varied in stream width, shading, surrounding land use, and the size of the riparian...
A microcosm designed for culturing aquatic phototrophic biofilms on artificial substrata was used to perform experiments with microphytobenthos sampled during summer toxic outbreaks of Ostreopsis cf. ovata along the Middle Tyrrhenian coast. This dyna...
Hydrothermal systems are ideal to understand how microbial communities cope with challenging conditions. Lirima, our study site, is a polyextreme, high-altitude, hydrothermal ecosystem located in the Chilean Andean highlands. Herein, we analyze the b...
Citrus is one of the most widely consumed fruits in the world, and its cultivation industry continues to develop rapidly. However, the roles of soil protistan communities during citrus growth are not yet fully understood, despite the potential signif...
In mountain regions, biological soil crusts (BSCs) provide essential ecological services by being involved in primary production and nitrogen fixation. Eukaryotic algae and cyanobacteria are important photosynthetic components of these unique cryptog...
Hydrological seasonality is a major driver of microbial community dynamics in river ecosystems, yet how seasonal flow regimes regulate protistan diversity, community assembly, and functional organization remains poorly understood. In this study, envi...
Knowledge of the features of the structure and productivity of the Arctic communities of marine planktonic algae is necessary to identify possible changes in the pelagic ecosystem functioning under the changing climate condition of the Kara Sea. This...
