Cyanobacteria are oxygen-producing photosynthetic bacteria that convert carbon dioxide into biomass upon exposure to sunlight. However, favorable conditions cause harmful cyanobacterial blooms (HCBs), which the dense accumulation of at water surface or subsurface, posing threats freshwater ecosystems and human health. Understanding mechanisms underlying bloom formation is crucial for effective management. In this regard, recent advancements in omics technologies have provided valuable insights HCBs, raised expectations develop more control methods near future. This systematic literature review aims present genomic architecture, adaptive mechanisms, microbial interactions, ecological impacts HCBs through lens omics. Genomic analysis indicates genome plasticity cyanobacteria has enabled their resilience adaptation environmental changes. Transcriptomic investigations revealed use various strategies adapting stress. Additionally, metagenomic metatranscriptomic analyses emphasized significant role community regulating HCBs. Finally, we offer perspectives on potential opportunities further research field.

Lake Reserv Manage. 39:1–20.The Ontario Ministry of Environment, Conservation and Parks samples algal composition response to public suspected blooms, which have been tracked since 1994. In a previous analysis, Winter et al. noted significant number confirmed dominated by cyanobacteria from 1994 2009. Here, we determined that this increasing trend yearly cyanobacterial bloom (CCBRs) has persisted over intervening decade, 2019. More than half CCBRs were waterbodies on Precambrian Shield, Georgian Bay (5E) ecoregion, known for cottaging water-based tourism. Data Partner Program (LPP) was used investigate total phosphorus (TP) concentrations with CCBRs. Approximately 44% CCBR (mean TP 12.99 µg/L, n = 135) had average spring less 10 compared 64% LPP no reported or 9.79 918). The most common taxon dominating inland Dolichospermum, followed Aphanizomenon Microcystis Mixedwood Plains ecozone southern Ontario. While an awareness cannot be ruled out contributing rise across high proportion occurring oligotrophic suggests there may link climate warming, rendering conditions more favorable these occur.

Cyanobacteria are the most common toxigenic algae in inland waters. Their toxins can affect health of aquatic and terrestrial organisms, including humans. Other algal groups, such as haptophytes (e.g., Prymnesium parvum) euglenoids Euglena sanguinea), also form harmful blooms (HABs) whose cause injury to biota but currently have no known effects on human health. parvum, however, is responsible for some worst HAB-related ecological disasters recorded Here, we provide an overview primary found U.S. waters: cyanobacteria (planktonic forms), P. E. sanguinea with objective describing their similarities differences areas HAB ecology, toxins, potential future range expansion HABs. A detailed account bloom habitats associations land cover use provided from perspective water quality. This review revealed that salinity may influence cyanobacterial cyanotoxins had not been fully recognized previously.

Cyanobacterial blooms are global threats to freshwater ecosystem functioning, human health, and ecoservices. We assessed impacts of cyanobacterial bloom intensity on plankton functioning using eukaryotic phytoplankton zooplankton indicators associated key physicochemical data collected from four seasons two years at 24 evenly distributed sites in Lake Taihu that has year-around blooms. Our analyses involved comparison site-groups with different intensities analyzing all sampling together comparison, hierarchical partitioning analysis, generalized additive mixed model, structural equation model. found abundance positively TP temperature (negatively TN:TP), while TN. There was an inverse relation trend between relative abundances cyanobacteria, but there no clear absolute cyanobacteria. Rotifers were most dominant when cyanobacteria unabundant, cladocerans presented higher high abundance. Phytoplankton functional richness species negatively intensity. resource use efficiencies (RUEs) rotifers, RUE cladocerans. analytical approach integrating uncovered how shifted altered biological conditions identified the mechanism strength interactive linkages among indicators. Although our results may be oligotrophic lakes or reservoirs, findings provide new insights understanding dynamics communities for polymictic eutrophic lakes, which have broad application enhancing knowledge this subject provides science base managing lake water quality functioning.

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
