Increases in atmospheric temperature and nutrients from land are thought to be promoting the expansion of harmful cyanobacteria lakes worldwide, yet date there has been no quantitative synthesis long-term trends. To test whether have increased abundance over past ~ 200 years evaluate relative influence potential causal mechanisms, we synthesised 108 highly resolved sedimentary time series 18 decadal-scale monitoring records north temperate-subarctic lakes. We demonstrate that: (1)...
The world’s water ecosystems have been affected by various human activities. Artificial intelligence techniques, especially machine learning, become an important tool for predicting the quality of inland aquatic ecosystems. As excellent biological indicator, chlorophyll-a was studied to determine state in Lake Llanquihue, located southern Chile. A 31-year time series (1989 2020) data collected situ used evolution limnological parameters at eight spaced stations covering all main points lake,...
Phytoplankton is considered a strong predictor of the environmental quality lakes, while Chlorophyll-a an indicator primary productivity. In this study, 25 LANDSAT images covering 2014–2021 period were used to predict in Villarrica lacustrine system. A recovery algorithm was calculated using two spectral indices (FAI and SABI). The that presented best statistical indicators floating algal index (R2 = 0.87) surface bloom 0.59). multiparametric linear model for estimation constructed with...

Over the past two decades, we observed a substantial rise in ionic content that was mainly determined by sulfate concentration at 20 remote high elevation lakes located central southern Himalaya. At LCN9, which monitored on an annual basis for last years, concentrations increased over 4-fold. Among main causes, exclude change composition of wet atmospheric deposition, as well possible influence decrease seasonal snow cover duration, could have exposed larger basin surfaces to alteration...
To understand interactions of lake physical characteristics, trophic dynamics and climate in Lago Maggiore, we compare longterm limnological meteorological monitoring data results from sediment cores. We include analyses nutrients, pigments, diatoms cladoceran microfossils. Over the past decades, caloric content increased. Eutrophication 1960s to early 1980s was followed by oligotrophication. DDTs, PCBs Hg showed high contamination '60s, compared point source inputs '90s. Algal biomass...
Cyanobacterial blooms occur in many parts of the world as a result entirely natural causes or human activity. Due to their negative effects on water resources, efforts are made monitor cyanobacteria dynamics. This study discusses contribution remote sensing methods for mapping cyanobacterial lakes northern Italy. Semi-empirical approaches were used flag scum and spectral inversion bio-optical models was adopted retrieve chlorophyll-a (Chl-a) concentrations. Landsat-8 OLI data provided us...
<p>The accurate quantification of cyanobacteria phycobiliproteins is an important aspect in various research topics, such as ecology and physiology studies, especially to calibrate algorithms used remote sensing cyanobacterial blooms. Here we present a spectroscopic approach, exploiting spectrophotometric equations, aimed at improving the phycocyanin allophycocyanin when chlorophyll <em>a</em> phycobiliprotein aqueous extract.</p>
We have studied laminated sediments from Lake Esmeralda, Vega Island, in order to reconstruct its history. describe both inorganic and organic components of the sediment using a combination following analytical methods: x-ray fluorescence (XRF), diffraction (XRD), magnetic susceptibility measurement, chemical analysis for determination cation exchange capacity, grain size determination, geochemical analyses (total carbon (TIC), total (TOC), sulphur (TS)), spectrophotometry, high-pressure...
