Phanerozoic Large Igneous Province, Petroleum System, and Source Rock Links

open access: yesGeophysical Monograph Series, Page 191-228., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

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 ...

Harmful Freshwater Algal Blooms, With an Emphasis on Cyanobacteria [PDF]

open access: yesThe Scientific World JOURNAL, 2001
Suspended algae, or phytoplankton, are the prime source of organic matter supporting food webs in freshwater ecosystems. Phytoplankton productivity is reliant on adequate nutrient supplies; however, increasing rates of nutrient supply, much of it manmade, fuels accelerating primary production or eutrophication.

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 ...

Development and field assessment of a quantitative PCR for the detection and enumeration of the noxious bloom-former Anabaena planktonica [PDF]

open access: yes, 2007
Anabaena planktonica is a harmful, bloom-forming freshwater cyanobacterium, which has arrived recently in New Zealand. In the short time since its incursion (

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.

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.

Dark side of cyanobacteria: searching for strategies to control blooms [PDF]

open access: yesMicrobial Biotechnology, 2021
Summary Cyanobacteria are ecologically one of the most prolific groups of photosynthetic prokaryotes in marine and freshwater habitats. They are primary producer microorganisms and are involved in the production of important secondary metabolites, including toxic compounds such as cyanotoxins.

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 ...
