Hypoxia Sustains Cyanobacteria Blooms in the Baltic Sea

Environmental Science & Technology, 2014
Nutrient over-enrichment is one of the classic triggering mechanisms for the occurrence of cyanobacteria blooms in aquatic ecosystems. In the Baltic Sea, cyanobacteria regularly occur in the late summer months and form nuisance accumulations in surface waters and their abundance has intensified significantly in the past 50 years attributed to human ...

Cyanobacteria Blooms in the Baltic Sea: A Review of Models and Facts [PDF]

Biogeosciences, 2020
Abstract. The ecosystem of the Baltic Sea is endangered by eutrophication. This has triggered expensive international management efforts. Some of these efforts are impeded by natural processes such as nitrogen-fixing cyanobacteria blooms that add bioavailable nitrogen to the already over-fertilised system and thereby enhance primary production, export ...

Insights into the physiology and ecology of the brackish-water-adapted cyanobacterium nodularia spumigena CCY9414 based on a genome-transcriptome analysis [PDF]

, 2013
Nodularia spumigena is a filamentous diazotrophic cyanobacterium that dominates the annual late summer cyanobacterial blooms in the Baltic Sea. But N. spumigena also is common in brackish water bodies worldwide, suggesting special adaptation allowing it ...

Molecular detection of hepatotoxic cyanobacteria in inland water bodies of the Marmara Region, Turkey

Advances in Oceanography and Limnology, 2017
Blooms of cyanobacteria are an increasingly frequent phenomenon in freshwater ecosystems worldwide as a result of eutrophication. Many species can produce hepatotoxins that cause severe health hazards to humans.

THE BLOOM AND TOXICITY OF CYANOBACTERIA IN LAKE SEVAN

Proceedings of the YSU B: Chemical and Biological Sciences, 2020
Seasonal hydrochemical, hydrophysical, and phytoplankton studies were conducted in a littoral zone of Lake Sevan in 2019. It is known that in recent years widespread algal blooms were usually started from the littoral zone of Big Sevan, and then spread towards the pelagic zone of the lake.

Hindcasting cyanobacterial communities in Lake Okaro with germination experiments and genetic analyses [PDF]

, 2009
Cyanobacterial blooms are becoming increasingly prevalent worldwide. Sparse historic phytoplankton records often result in uncertainty as to whether bloom-forming species have always been present and are proliferating in response to eutrophication or ...

High capacity for a dietary specialist consumer population to cope with increasing cyanobacterial blooms

Scientific Reports, 2022
We present a common-garden experiment to examine the amphipod Monoporeia affinis, a key deposit-feeder in the Baltic Sea, a low diversity system offering a good model for studying local adaptations.
