Abstract Freshwater environments teem with microbes that do not have counterparts in culture collections or genetic data available genomic repositories. Currently, our apprehension of evolutionary ecology freshwater bacteria is hampered by the difficulty to establish organism models for most representative clades. To circumvent bottlenecks inherent cultivation-based techniques, we applied ecogenomics approaches order unravel history and processes drive genome architecture hallmark lineages...
Abstract Background The phytoplankton spring bloom in freshwater habitats is a complex, recurring, and dynamic ecological spectacle that unfolds at multiple biological scales. Although enormous taxonomic shifts microbial assemblages during after the have been reported, genomic information on community of remains scarce. Results We performed high-resolution spatio-temporal sampling reservoir describe multitude previously unknown taxa using metagenome-assembled genomes eukaryotes, prokaryotes,...
Biomonitoring of complex heterogeneous environments is highly challenging. Fish in deep water bodies occupy different habitats, so a combination survey methods has traditionally been used. Environmental DNA (eDNA) metabarcoding novel monitoring tool that can overcome spatial heterogeneity sensitive and entirely non-invasive manner. However, taxon detection probability dependent on environmental variables. In this study, three reservoirs were sampled two seasons using spatiotemporally...
Abstract Background Planktonic microbial communities have critical impacts on the pelagic food web and water quality status in freshwater ecosystems, yet no general model of bacterial community assembly linked to higher trophic levels hydrodynamics has been assessed. In this study, we utilized a 2-year survey planktonic from bacteria zooplankton three reservoirs investigate their spatiotemporal dynamics. Results We observed site-specific occurrence microdiversification lacustrine riverine...
Summary Diatoms are one of the most important phytoplankton groups. As they grow, diatoms use silicon to produce a siliceous frustule, which protects cell. During A pril– N ovember 2011, at 1–3 week intervals, we estimated diatom silicification rates two distinct sites along longitudinal profile canyon‐shaped eutrophic Římov Reservoir (Czech Republic): (i) nutrient‐depleted lacustrine zone near dam and (ii) nutrient‐rich transition upstream river inflow. Diatom was using 24‐h in situ...
Zoosporic parasites (i.e. fungi and fungi-like aquatic microorganisms) constitute important drivers of natural populations, causing severe host mortality. Economic impacts parasitic diseases are notable in the microalgae biotech industry, affecting production food ingredients, biofuels, pharma- nutraceuticals. While scientific research on this topic is gaining traction by increasing studies elucidating functional role zoosporic ecosystems, we currently lacking integrated interdisciplinary...

Abstract Background Protists are essential contributors to eukaryotic diversity and exert profound influence on carbon fluxes energy transfer in freshwaters. Despite their significance, there is a notable gap research protistan dynamics, particularly the deeper strata of temperate lakes. This study aimed address this by integrating protists into well-described spring dynamics Římov reservoir, Czech Republic. Over 2-month period covering transition from mixing established stratification, we...
SUMMARY Diatoms are known to exploit organic substrates for growth; however, convincing evidence that they can utilize dissolved carbon under natural conditions is not available. In 2008–2009, we performed in situ experiments examining the effect of glucose addition on silica deposition kinetics and growth rates Fragilaria crotonensis eutrophic Římov Reservoir (Czech Republic). Silica was measured at 4‐h intervals over a 24‐h incubation with PDMPO...
Despite the high functional importance of endophytes, we still have limited understanding biotic and abiotic factors that influence colonization plant hosts along major ecological gradients lack quantitative estimates their extent. In this study, hypothesized developmental stage ecosystem will affect levels bacterial fungal endophytic assemblages in foliar endosphere.

In this study, a remote sensing-based method of mapping and predicting fish spatial distribution in inland waters is developed. A combination Earth Observation data, in-situ measurements, hydroacoustics used to relate biomass water-quality parameters along the longitudinal transect Římov Reservoir (Czech Republic) using statistical machine learning techniques. Parameter variations are estimated validated, apparent trends explored discussed, together with potential limitations weaknesses....
Abstract To understand the conditions of coexistence in multiple-species predator community, we studied longitudinal and vertical movement pike ( Esox lucius ), pikeperch Sander lucioperca ) catfish Silurus glanis Římov Reservoir, using an autonomous telemetry system for 11 months. We found significant differences among these three species depth that varied considerably time, with greatest between warm (late spring early autumn) cold season autumn to spring). Preference different sections...
Abstract Freshwater environments teem with microbes. Currently, our apprehension of evolutionary ecology freshwater bacteria is hampered by the difficulty to establish organism models for most representative clades. To circumvent bottlenecks inherent cultivation-based techniques, we applied ecogenomics approaches in order unravel history and processes that drive genome architecture hallmark lineages from Planctomycetes phylum. The inferences showed sediment/soil transitioned aquatic were,...
