Microbial‐mediated recycling constrains the contribution of primary production to export flux in an oligotrophic system

open access: yesLimnology and Oceanography, Volume 71, Issue 1, January 2026.
Abstract This study presents the first multi‐year assessment quantifying the contribution of primary production to vertical carbon flux in the ultra‐oligotrophic southeastern Levantine basin of the Mediterranean Sea. Depth‐integrated (0–180 m) daily primary productivity (PP) was 25% higher in the mixed winter period than in the stratified period (123 ...

Major contribution of particle‐associated microbes to deep‐sea organic carbon degradation

open access: yesLimnology and Oceanography, Volume 71, Issue 1, January 2026.
Abstract The biological carbon pump mediates the export of particulate organic carbon from the euphotic zone to the deep ocean, where it provides the base of the food web. Although deep‐sea microbial metabolism is considered to be largely associated with macroscopic particles, such as marine snow, the specific contribution of particle‐associated ...

Tightly coupled carbon, nitrogen, and iron utilization by bacteria in the lower photic zone of the North Pacific Subtropical Gyre

open access: yesLimnology and Oceanography, Volume 71, Issue 1, January 2026.
Abstract The metabolism of heterotrophic bacteria acts as a key control on the turnover of organic matter in the ocean. However, much remains unknown about how nutrient availability, particularly iron concentration, impacts bacterial growth. In the dimly lit waters of the lower photic and upper mesopelagic zones, the attenuation of sinking particulate ...

Heatwaves and a history of variability shape phytoplankton community thermal responses within one generation

open access: yesLimnology and Oceanography, Volume 71, Issue 1, January 2026.
Abstract Predicting the effect of increased thermal unpredictability, for example in the shape of heatwaves on phytoplankton metabolic responses is ripe with challenges. While single genotypes in laboratory environments will respond to environmental fluctuations in predictable and repeatable ways, it is difficult to relate rapid evolutionary responses ...

Efficacy of Modified Bioactive Glass for Dentin Remineralization and Obstruction of Dentinal Tubules

open access: yesFrontiers in Dentistry, 2017
Objectives: This study assessed the efficacy of modified bioactive glass (MBG) for dentin remineralization and obstruction of dentinal tubules. Materials and Methods: Thirty-six dentin discs were made from 20 third molars and were stored in 12% lactic ...

Coupling air–water CO2 flux and primary production dynamics under hydrologic variability in a large urban estuary

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 1, January 2026.
Abstract Estuaries are critical for land‐ocean carbon exchange, but coupling mechanisms between air–sea CO2 fluxes (FCO2) and phytoplankton gross primary productivity (GPP) remain poorly understood. This study used high‐frequency underway monitoring in the Lingdingyang Estuary to resolve spatiotemporal interplays between FCO2 and GPP.

Wave‐driven transport controls bacterioplankton community differentiation among coral reef habitats

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 1, January 2026.
Abstract The existence of highly productive coral reefs within oligotrophic gyres is in part due to intensive recycling of macronutrients and organic matter by microbes. Therefore, characterizing reef bacterioplankton communities is key for understanding reef metabolism and biogeochemical transformations. We performed a high‐resolution survey of waters
