Dynamic Phycobilin Pigment Variations in Diazotrophic and Non-diazotrophic Cyanobacteria Batch Cultures Under Different Initial Nitrogen Concentrations

open access: yesFrontiers in Microbiology, 2022
Increased anthropogenic nutrient loading has led to eutrophication of aquatic ecosystems, which is the major cause of harmful cyanobacteria blooms. Element stoichiometry of cyanobacteria bloom is subject to nutrient availabilities and may significantly ...

Social Construction of Cyanobacteria Blooms in Quebec [PDF]

open access: yesSAGE Open, 2017
Using a political ecology perspective, this research examines the social issues of cyanobacteria. In Québec (Canada), public health officials issue warnings concerning water-related activities and water consumption. An ethnographic study was undertaken with the aim of gaining a better understanding of the attitudes of citizens toward cyanobacteria and ...

Cyanobacterial Akinete Distribution, Viability, and Cyanotoxin Records in Sediment Archives From the Northern Baltic Sea

open access: yesFrontiers in Microbiology, 2021
Cyanobacteria of the order Nostocales, including Baltic Sea bloom-forming taxa Nodularia spumigena, Aphanizomenon flosaquae, and Dolichospermum spp., produce resting stages, known as akinetes, under unfavorable conditions.

Summer heatwaves promote blooms of harmful cyanobacteria [PDF]

open access: yesGlobal Change Biology, 2007
AbstractDense surface blooms of toxic cyanobacteria in eutrophic lakes may lead to mass mortalities of fish and birds, and provide a serious health threat for cattle, pets, and humans. It has been argued that global warming may increase the incidence of harmful algal blooms.

Long-Term Spatial and Temporal Monitoring of Cyanobacteria Blooms Using MODIS on Google Earth Engine: A Case Study in Taihu Lake

open access: yesRemote Sensing, 2019
As cyanobacteria blooms occur in many types of inland water, routine monitoring that is fast and accurate is important for environment and drinking water protection. Compared to field investigations, satellite remote sensing is an efficient and effective

Seasonal constraints on the burial of organic carbon in the eutrophic Lake Taihu

open access: yesFrontiers in Earth Science, 2023
Eutrophication alters the function of lake ecosystems through phytoplankton blooms and is a major contributor to organic carbon (OC) burial in lakes worldwide.

Freshwater bloom‐forming cyanobacteria and anthropogenic change [PDF]

open access: yesLimnology and Oceanography e-Lectures, 2017
This lecture (∼ 45‐55 slides) will be aimed at senior undergraduate students and graduate students in aquatic sciences with little background in phycology. This lecture could be used in a Aquatic Ecology or Sciences (Limnology) course, an Ecology course, a Phycology course, Environmental Science.Cyanobacteria that may lead to blooms encompass a wide ...

A study of cyanobacterial bloom monitoring using unmanned aerial vehicles, spectral indices, and image processing techniques

open access: yesHeliyon, 2023
Last 5 years, the deterioration of water quality caused by algal bloom has emerged as a serious issue in Korea. The method of on-site water sampling to check algal bloom and cyanobacteria is problematic by only partially measuring the site and not fully ...

The genus Sphaerocavum and the dominance of S. brasiliense and Microcystis wesenbergii (Microcystaceae, Cyanophyceae) in the algae bloom of Huacachina lagoon, Peru

open access: yesRevista Peruana de Biología, 2016
The present work registers for the first time the cyanobacteria Sphaerocavum brasiliense Azevedo y Sant’Anna and Microcystis wesenbergii (Komárek) Komárek in Kondrateva (Microcystaceae, Cyanophyceae) in an algal bloom on Huacachina lagoon (Ica ...

Hypoxia Sustains Cyanobacteria Blooms in the Baltic Sea

open access: yesEnvironmental 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 ...
