Climate change has increased the frequency, duration and intensity of heatwaves in Europe. These extreme events result alterations physical, chemical, biological properties lakes that may synergistically promote cyanobacterial dominance. In our study we focused on blooms distributed over a longitudinal gradient Central Europe during one "top ten European heat waves" summer 2015. 92 were included study, located across three climatic subregions: cool northern lakes, situated Lithuania, temperate Poland, warm Croatia. The objective was to determine if biomass, predominant species, cyanotoxin concentration differed, south-north gradient, as function water temperature, total phosphorus, nitrogen. Statistical significance observed patterns tested using Kruskal-Wallis rank sum test generalized linear model. We found lowest average epilimnion but highest biomass northern, 'cool' while temperature with southern, 'warm' lakes. cyanotoxins also Total phosphorus nitrogen correlated significantly some species (mainly Planktothrix agardhii), regardless latitude. Only (microcystins anatoxin-a) dominant (P. agardhii). Our results emphasized differences weaves impact various latitudes, strongest increase toxic high latitudes. On other hand, nutrients directly enhanced all studied latitudes cyanobacteria dominating might be recognized ecological indicators climate change, especially north-eastern part

Abstract To determine the drivers of phytoplankton biomass, we collected standardized morphometric, physical, and biological data in 230 lakes across Mediterranean, Continental, Boreal climatic zones European continent. Multilinear regression models tested on this snapshot mostly eutrophic (median total phosphorus [TP] = 0.06 nitrogen [TN] 0.7 mg L −1 ), its subsets (2 depth types 3 zones), show that light climate stratification strength were most significant explanatory variables for chlorophyll a (Chl ) variance. TN was predictor biomass shallow continental lakes, while TP never appeared as an variable, suggesting under high TP, light, which partially controls strength, becomes limiting development. Mediterranean warmest yet weakly stratified had significantly less Chl than where temperature anomaly from long‐term average, during summer heatwave highest (+4°C) showed significant, exponential relationship with strength. This survey represents drivers, lends support metrics, are both affected by change, better predictors nutrient‐rich nutrient concentrations surface temperature.

Abstract Cyanobacterial blooms have substantial direct and indirect negative impacts on freshwater ecosystems including releasing toxins, blocking light needed by other organisms, depleting oxygen. There is growing concern over the potential for climate change to promote cyanobacterial blooms, as positive effects of increasing lake surface temperature growth are well documented in literature; however, there evidence that also being initiated persisting relatively cold‐water temperatures (< 15°C), ice‐covered conditions. In this work, we provide review abiotic drivers physiological adaptations leading these offer a typology lesser‐studied discuss their occurrence under changing

The study evaluated the effect of environmental conditions and morphometric parameters on lake water temperature changes. analysis was carried out basis 14 lakes located in northern Poland. assessment based daily air temperatures from 1972 to 2016. It took into account location (latitude, longitude, altitude) (surface area, maximum mean depth, volume), hydrological processes (rate exchange, course ice phenomena), trophic status (water transparency) as factors that can modify Direction rate changes were analysed by means Mann–Kendall’s Sen’s tests. Cluster (CA) applied group characterised similar climatic non-climatic a lake’s assessed principal component (PCA). Water years 1972–2016 higher increase 0.43 °C·dec−1 than decrease 0.34 °C·dec−1. showed faster heating waters western This be explained shorter duration cover. Moreover, affected other factors, including lakes, their parameters, wind speed, transparency exchange time.

Abstract Climate change and the intensification of land use practices are causing widespread eutrophication subarctic lakes. The implications this rapid for lake ecosystem function remain poorly understood. To assess how freshwater communities respond to such profound changes in their habitat resource availability, we conducted a space‐for‐time analysis food‐web structure 30 lakes situated across temperature‐productivity gradient equivalent predicted future climate Europe (temperature +3°C, precipitation +30% nutrient +45 μg L −1 total phosphorus). Along gradient, observed an increase assimilation pelagic‐derived carbon from 25 75% throughout primary, secondary tertiary consumers. This shift was overwhelmingly driven by consumption pelagic detritus benthic primary consumers not accompanied increased foraging higher trophic level Our data also revealed convergence isotope ratios food web endmembers warmest, most productive indicating that incorporation terrestrial derived into aquatic webs increases as intensifies. These results, reflecting along characteristic environment subarctic, indicate browning radically altering fuelling biome.

Small, surface-release dams are ubiquitous features of the landscape that typically slow water flow and decrease canopy cover through impounded reaches, potentially increasing stream temperatures. However, reported effects small on temperature variable, likely due to differences in dam characteristics. To quantify range thermal dams, we deployed continuous loggers for one four years at 30 sites across a environmental settings throughout Massachusetts (USA). Most (67%) warmed downstream waters, with August mean temperatures 0.20–5.25 °C higher than upstream. Downstream cooled increased distance from 68% sites, such warmest were observed closest dam. Where there was both significant warming effect cooling pattern (seven sites), elevated persisted an average 1.31 km Dams impoundments caused greatest relative widening channel those coldwater streams had most warming, while short forested watersheds quickly Flow homogenizing over half whereby summer impacts more pronounced (e.g., faster rates) under periods lower flows. may reduce habitat fishes invertebrates, particularly where shift coldwater/coolwater warmwater. These results suggest removal mitigate increase ecosystem resilience face changing climate via restoration critical habitats.

Abstract The interacting effects of global changes—including increased temperature, altered precipitation, reduced acidification and dissolved organic matter loads to lakes—are anticipated create favourable environmental conditions for cyanobacteria in northern lakes. However, responses these changes are complex, if not contradictory. We hypothesized that absolute relative biovolumes (both total specific genera) increasing Swedish nutrient‐poor lakes increases associated with changes. tested hypotheses using data from 28 over 16 years (1998–2013). Increases biovolume were identified 21% the study sites, primarily southeastern region Sweden, composed mostly three genera: Merismopedia , Chroococcus Dolichospermum .
