Global warming has been shown to strongly influence inland water systems, producing noticeable increases in water temperatures. Rising temperatures, especially when combined with widespread nutrient pollution, directly favour the growth of toxic cyanobacteria. Climate changes have also altered natural water level fluctuations increasing the probability of extreme events as dry periods followed ...
Many species of phytoplankton are susceptible to parasitism by fungi from the phylum Chytridiomycota (i.e. chytrids). However, few studies have reported the effects of fungal parasites on filamentous cyanobacterial blooms. To investigate the missing components of bloom ecosystems, we examined an entire field bloom of the cyanobacterium Anabaena macrospora for evidence of chytrid infection in a ...
Some lakes in China have undergone serious eutrophication, with cyanobacterial blooms occurring frequently. Dynamic monitoring of is important. At present, the traditional lake-survey-based bloom spatiotemporally limited and requires considerable human material resources. Although satellite remote sensing can rapidly monitor large-scale blooms, clouds other factors often mean that effective ima...
Appreciation is given to all those whose efforts made the production of this book possible. Thanks are due to the editors, Anthony Fristachi, US Environmental Protection Agency, Office of Research and Development, Cincinnati, Ohio and Jim Sinclair, PhD, US Environmental Protection Agency. Thanks are also due to Dr. Jeffrey Johansen of John Carroll University for his review and revisions to the ...
Climate change is enhancing the frequency of cyanobacterial blooms not only during summer but also in spring and autumn, leading to increased ecological impacts. The bacterioplankton community composition (BCC), particular, deeply affected by these blooms, although at same time BCC can play important roles blooms’ dynamics. However, more information still needed regarding species-specific bloom...
Cyanobacterial blooms appear by complex causes such as water quality, climate, and hydrological factors. This study aims to present the machine learning models predict occurrences of these complicated cyanobacterial efficiently effectively. The dataset was classified into groups consisting two, three, or four classes based on cell density after a week, which used target variable. We developed 9...
Blooms of nitrogen-fixing cyanobacteria are recurrent phenomena in marine and freshwater habitats, and their supplying role in aquatic biogeochemical cycles is generally considered vital. The objective of this study was to analyse whether an increasing proportion of nitrogen-fixing cyanobacteria affects (i) the composition of the non-diazotrophic component of ambient phytoplankton communities a...
