Transient Ecological Niches for Diazotrophs in Upwelling Bays
Journal 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

Diel and Artificial Light Effects on Nearshore Communities Revealed by eDNA Metabarcoding
Environmental DNA, Volume 8, Issue 4, July‐August 2026.Environmental DNA revealed rapid, taxon‐specific community reorganization across diel and artificial light conditions in a nearshore marine ecosystem. Distinct responses among trophic groups indicate that artificial light at night reshapes predator–prey interactions and community structure within 30 min of exposure.

An updated view on the long‐term survival and significance of marine protist resting stages
Limnology and Oceanography Letters, Volume 11, Issue 4, July 2026.Abstract Resting stages of protists act as biological time capsules when buried in marine sediments, preserving viable cells that enable the study of ecological and evolutionary processes across timescales. Recent studies have extended the known viability in diatoms to several millennia and in dinoflagellates to over a century, while also identifying ...
