Global Carbon Investment in Terrestrial Biological Nitrogen Fixation

open access: yesGlobal Biogeochemical Cycles, Volume 40, Issue 8, August 2026.
Abstract Biological nitrogen (N) fixation (BNF) provides the N needed to produce proteins and other biological building blocks, helping feed humanity and mitigate climate change. Due to its high energetic cost compared to other forms of N acquisition, biotic investment in BNF indicates N limitation. Globally gridded BNF flux data provide an opportunity

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

Identifying climatic refugia: Wet and complex habitats act as buffer for birds during severe droughts

open access: yesJournal of Applied Ecology, Volume 63, Issue 8, August 2026.
Wet habitats and complex vegetation, therefore, are critical for providing stable microsites and water resources, underscoring the need to preserve and enhance the resilience of these habitats to support biodiversity during extreme events. Our study provides valuable insights for conservation strategies that should focus on identifying refugia ...

Spatial Partitioning of Microbial Functional Potential Suggests Complex Nitrogen Cycling in a Subterranean Estuary

open access: yesEnvironmental Microbiology, Volume 28, Issue 8, August 2026.
Microbial communities in a Mediterranean subterranean estuary show spatially structured nitrogen‐cycling potential across hydrochemical zones. Microbial properties, more than environmental variables, predict NO2− and NH4+ concentrations, highlighting their key role in controlling nitrogen transformations prior to submarine groundwater discharge ...
