Whitings in the Red Sea

The Depositional Record, Volume 12, Issue 1, February 2026.
We present the first documentation of whitings in the Red Sea, observed in a lagoonal environment. These events are linked to cascading offshore dense waters that liberate trapped sea floor nutrients, triggering algal blooms and elevating alkalinity, which is buffered by direct CaCO3 precipitation—contributing to the accumulation of aragonite mud in ...

A critical role of heterotrophic bacteria in early diagenesis of carbonates through exopolymer degradation and calcium release

The Depositional Record, Volume 12, Issue 1, February 2026.
Exopolymeric substances (EPS) produced in the photic zone and surface sediments sequester calcium. Below the sediment surface, heterotrophic bacteria degrade EPS, releasing calcium resulting in carbonate precipitation. This process, which continues for millennia deep in the core, is an important sink for atmospheric carbon dioxide.

Spatiotemporal dynamics of microbial communities and cyanobacteria blooms in two North American Lakes using long-read 16S rRNA sequencing

Ecological Indicators
Understanding spatial and temporal heterogeneity in ecosystems is essential to forecasting the effects of environmental changes. Freshwater microbes, including cyanobacteria, play a crucial role in food-web structures and biochemical processes, yet can ...

Contribution of bioturbation by the red swamp crayfish Procambarus clarkii to the recruitment of bloom-forming cyanobacteria from sediment

Journal of Limnology, 2010
The development of cyanobacterial blooms in a small eutrophic pond was monitored along with the potential effect of bioturbation by the red swamp crayfish Procambarus clarkii discussed as well with respect to the recruitment of cyanobacteria from ...

Inhibition effect of engineered silver nanoparticles to bloom forming cyanobacteria

, 2016
Silver nanoparticle (AgNP) has a wide range antibacterial effect and is extensively used in different aspects of medicine, food storage, household products, disinfectants, biomonitoring and environmental remediation etc. In the present study, we examined

Seasonality in Marine Organic Carbon Export and Sequestration Pathways

Global Biogeochemical Cycles, Volume 40, Issue 2, February 2026.
Abstract The ocean's biological carbon pump transports organic carbon from the surface to depth via three main pathways: the gravitational sinking of particles, active transport by vertically migrating zooplankton, and mixing and advection of suspended and dissolved organic carbon.

First Report of a Toxic Nodularia spumigena (Nostocales/ Cyanobacteria) Bloom in Sub-Tropical Australia. I. Phycological and Public Health Investigations

International Journal of Environmental Research and Public Health, 2012
Cyanobacterial blooms represent one of the most conspicuous and widespread waterborne microbial hazards to human and ecosystem health. Investigation of a cyanobacterial bloom in a shallow brackish water recreational cable ski lake in south-eastern ...

First Report of a Toxic Nodularia spumigena (Nostocales/ Cyanobacteria) Bloom in Sub-Tropical Australia. II. Bioaccumulation of Nodularin in Isolated Populations of Mullet (Mugilidae)

International Journal of Environmental Research and Public Health, 2012
Fish collected after a mass mortality at an artificial lake in south-east Queensland, Australia, were examined for the presence of nodularin as the lake had earlier been affected by a Nodularia bloom.

Ecological, Functional, and Phylogenetic Determinants of Cyanobacterial Biomineralisation

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
Cyanobacteria contribute to the global carbon cycle by biomineralising CO2 into solid carbonates. Unlike photosynthesis, biomineralisation is a less‐understood, multifaceted and adaptive metabolic process with significant global impact. It involves cell wall structures, genetic factors, and metabolic pathways that enable mineral formation and help ...
