Abstract Ciliates are unicellular heterotrophic organisms that play a key role in aquatic planktonic and benthic food webs. Advances sedimentary DNA (sed-DNA) analysis offer the possibility to integrate these bioindicators paleoenvironmental reconstructions. In this study, we used top–bottom paleolimnological approach metabarcoding techniques applied sed-DNA compare recent past (i.e. prior major anthropogenic impacts) ciliate communities of 48 lakes located along an elevation gradient. Our results show overall decline β-diversity time, especially lowland lakes, which more strongly exposed local human pressures. Analyses functional groups indicate important restructuration web, including increase mixotrophs. Moreover, changes ciliates were consistent with widespread deep water anoxia. provided evidence can uncover information about on wide variety lakes. Overall, our study demonstrates potential using as new paleoindicators, integrating from pelagic zones, providing valuable insights into ecosystem functioning through trait-based community approach. As paleoindicator, they thus holistic view long-term ecosystems.

Water quality related to non-point source pollution continues pose challenges in agricultural landscapes, despite two completed cycles of Framework Directive actions by farmers and landowners. Future climate projections will cause new landscape hydrology subsequently, the potential responses water quality. Investigating nutrient trends surface waters studying efficiency mitigation measures revealed that loads are highly variable both spatially temporally catchments with different agro-climatic environmental conditions. In Sweden, nitrogen phosphorus eight (470-3300 ha) have been intensively monitored for >20 years. This study investigated relationship between precipitation, air temperature, discharge patterns relation (N) (P) at catchment outlets. The time series data analysis was carried out integrating Mann-Kendall test, Pettitt break-points, Generalized Additive Model. results showed depend on discharge, which had large variation annual average (158-441 mm yr-1). were also considerably among total N (TN) ranging from 6.76 35.73 kg ha-1, P (TP) 0.11 1.04 ha-1. climatic drivers significant indicators but varying degree significance. Precipitation (28-962 yr-1) a indicator TN five (loamy sand/sandy loam) while temperature (6.5-8.7 °C driver six catchments. TP associated precipitation significantly correlated Considering more frequent occurrence extreme weather events, it is necessary tailor future climate-change features discharge.

Compounded weather events such as sequential heatwaves are likely to increasingly impact freshwater ecosystems in the future. Satellite-derived chlorophyll-a concentration estimates for 36 European lakes during a widespread double heatwave event summer of 2019 show that deep and medium depth at higher latitudes displayed synchronous increase with temperature, possibly result an improved light climate resulting from increased stratification. Many or northern had notable response heatwaves. Warmer, southern shallow most asynchronous response, tending greater subsequent low pressure storm than itself. Chlorophyll-a peaks typically occurred five days after peak lakes. For some lakes, cycle several was found punctuate seasonal pattern chlorophyll-a. Notably, these nutrient-rich dwarfed by large algal blooms occurring later typical cyanobacterial bloom period early autumn, underlining importance timing phenology addition depth, latitude trophic state.
