Influence of Deep‐Sea Carbonate Sediments on the Long‐Term Durability of Carbon Storage From Ocean Alkalinity Enhancement

open access: yesGlobal Biogeochemical Cycles, Volume 40, Issue 8, August 2026.
Abstract Ocean Alkalinity Enhancement (OAE) is a marine carbon dioxide removal (CDR) strategy with a theoretical sequestration potential of several Gt CO2 ${\mathrm{C}\mathrm{O}}_{2}$ yr−1 ${\mathrm{y}\mathrm{r}}^{-1}$. The long‐term durability of OAE‐induced carbon storage depends on the persistence of the added alkalinity in the ocean, which is ...

Transient Ecological Niches for Diazotrophs in Upwelling Bays

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Diazotrophs, microorganisms capable of fertilizing the ocean through biological nitrogen fixation (BNF), are widespread in the oceans, including upwelling bays. However, their ability to respond to short‐lived upwelling pulses, lasting only a few days, remains poorly understood. To investigate diazotrophy across temporal scales, we analyzed 18

Optimizing a long‐term monitoring strategy to track emerging cyanobacterial blooms in a Great Lakes estuary

open access: yesJournal of Phycology, Volume 62, Issue 4, Page 1264-1296, August 2026.
Abstract Cyanobacterial harmful algal blooms (cHABs) are increasingly frequent and severe globally. Recently, the St. Louis River Estuary (SLRE) has experienced numerous cHABs, but the locations, timing, and environmental conditions associated with them are unknown.

Conserved symbiosis‐associated genes in the cycad Encephalartos natalensis suggest co‐option for cyanobacterial symbiosis

open access: yesNew Phytologist, Volume 251, Issue 4, Page 2168-2185, August 2026.
The heterocyst‐rich Encephalartos natalensis cyanobacterial zone in coralloid root suggests co‐option of conserved symbiosis‐associated genes. This figure was created in BioRender (BioRender.com/https://BioRender.com/n3qveqc). Summary Plant‐cyanobacterial symbioses have evolved independently at least four times across land plants, yet their underlying ...

The Madagascar Bloom – a serendipitous study [PDF]

open access: yes, 2013
The late austral summer (February-April) phytoplankton bloom that occurs east of Madagascar exhibits significant interannual variability and at its largest extent covers ~1% of the world’s ocean surface area.

Impacts of organic and conventional crop management on diversity and activity of free-living nitrogen fixing bacteria and total bacteria are subsidiary to temporal effects [PDF]

open access: yes, 2012
A three year field study (2007-2009) of the diversity and numbers of the total and metabolically active free-living diazotophic bacteria and total bacterial communities in organic and conventionally managed agricultural soil was conducted at the ...

Influence of the Mississippi River plume on diazotroph distributions in the northern Gulf of Mexico during summer 2011 [PDF]

open access: yes, 2012
textIn the subtropical oligotrophic ocean, nitrogen fixation is an important source of new nitrogen (N) for supporting biological production. Previous studies have found that nitrogen-fixing Diatom-Diazotroph Associations (DDAs) are in high abundance in ...

Protistal Grazers Increase Grazing on Unicellular Cyanobacteria Diazotroph at Night

open access: yes, 2020
In this study, we have for the first time analyzed diel microzooplankton grazing selectivity on unicellular cyanobacterial diazotroph (i.e., Crocosphaera watsonii WH8501) and non-diazotrophic unicellular microalga (i.e., Chlorella autotrophica).

Specificity of salt marsh diazotrophs for vegetation zones and plant hosts

open access: yesFrontiers in Microbiology, 2012
Salt marshes located on the east coast of temperate North America are highly productive, typically nitrogen-limited, and support diverse assemblages of nitrogen fixing (diazotrophic) bacteria.

Ectomycorrhizal fungi significantly shape endorhizal bacteria associated with Pinus taiwanensis in heavy metal soils

open access: yesEcosphere
The understanding of ectomycorrhizal (ECM) fungi's role in shaping bacterial groups and regulating heavy metals in soils was limited in the past. A mesocosm experiment with inoculation treatments (Pezicula ericae K2 and Pisolithus tinctorius) was applied
