Marine Phytoplankton Extremes and Compound Extreme Events Have the Potential to Be Predicted Multiple Months in Advance

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Global marine primary producers, phytoplankton, are the base of the marine food web and vary on short timescales, characterized by seasonal blooms. There is growing concern about the occurrence of short‐term extreme events in phytoplankton abundance, which may impact higher trophic levels and economically‐important species.

Rhizobia Isolated from Coal Mining Areas in the Nodulation and Growth of Leguminous Trees

Revista Brasileira de Ciência do Solo, 2016
An alternative for recovery of areas degraded by coal mining is revegetation with rapidly growing leguminous trees, which often do not establish in low fertility soils.

Soil Microbiota and Rhizosphere Dynamics: Ecological Mechanisms Driving Crop Stress Adaptation in Climate‐Smart Agriculture

Food and Energy Security, Volume 15, Issue 4, July/August 2026.
ABSTRACT Climate change‐mediated abiotic stresses limit crop performance, and plant responses are increasingly recognized as emergent properties of the coupling between soil, plants, and microbiomes rather than inherent plant characteristics. This review synthesizes mechanistic evidence from 2020 to 2025 on how rhizosphere microbiota contribute to crop

Increase in Summer–Fall Chlorophyll Blooms in the Northeastern Pacific Subtropical Gyre Over the Past Three Decades

Journal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.
Abstract Large chlorophyll blooms spanning hundreds of square kilometers and persisting for weeks‐months, have been repeatedly observed in satellite records of ocean color in the North Pacific Subtropical Gyre (NPSG). These blooms, typically defined as chlorophyll concentrations exceeding some threshold (generally ∼0.15 mg m−3), occur uniquely within ...

The Isolation of Free-Living Nitrogen-Fixing Bacteria and the Assessment of Their Potential to Enhance Plant Growth in Combination with a Commercial Biostimulant

Microbiology Research
The development of microbial-based biostimulants to enhance the growth of crops and support a healthy and sustainable soil requires the isolation and large-scale industrial culture of effective microorganisms.

Diazotrophic Macroalgal Associations With Living and Decomposing Sargassum

Frontiers in Microbiology, 2018
Despite several studies reporting diazotrophic macroalgal associations (DMAs), biological nitrogen fixation (BNF) is still largely overlooked as a potential source of nitrogen (N) for macroalgal productivity. We investigated the role of BNF, via the acetylene reduction method, throughout different life stages of the invasive macroalga, Sargassum ...

Filtration via Conventional Glass Fiber Filters in 15N2 Tracer Assays Fails to Capture All Nitrogen-Fixing Prokaryotes

Frontiers in Marine Science, 2018
Biological dinitrogen fixation (BNF) represents a major input of reduced nitrogen (N) to the oceans. Accurate direct measurements of BNF rates are crucial for reliably determining the biogeochemical significance of diazotrophy at local and global scales.

Assimilation of Diazotrophic Nitrogen into Pelagic Food Webs

PLoS ONE, 2013
The fate of diazotrophic nitrogen (N(D)) fixed by planktonic cyanobacteria in pelagic food webs remains unresolved, particularly for toxic cyanophytes that are selectively avoided by most herbivorous zooplankton. Current theory suggests that N(D) fixed during cyanobacterial blooms can enter planktonic food webs contemporaneously with peak bloom biomass

Diazotrophic bacteria in star flowers

Bioscience Journal, 2012
This study evaluated the occurrence and density of associative diazotrophic bacteria in the rhizosphere, collar, roots and leaves of Syngonanthus elegans (Bong) Ruhland (Goldenfoot) and Syngonanthus aciphyllus (Mini-skirt). These species are able to grow in poor soils. Five samples, with 25 plants both of S. elegans and S.

Soil Erosion Thickness and Seasonal Variations Together Drive Soil Nitrogen Dynamics at the Early Stage of Vegetation Restoration in the Dry-Hot Valley

Microorganisms
By changing the physicochemical and biological properties of soil, erosion profoundly affects soil nitrogen levels, but knowledge about the erosion impact on soil nitrogen (N) dynamics is still rather incomplete.
