Late Jurassic Carbon Isotope Excursion (Middle Oxfordian Event) Paces With Astronomical Forcing in the Northwestern Tethys

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Marine carbonate carbon isotopes (δ13C), over orbital to multi‐million‐year timescales, provide critical insight into the carbon cycle connecting Earth's atmosphere, lithosphere, hydrosphere and biosphere. However, the influence of astronomical forcing on deep time carbon cycle dynamics remains poorly constrained.

Spatial and Temporal Patterns of Alkalinity in an Alpine Headwater Stream Network: Linking Catchment Heterogeneity to Carbon Dynamics

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.
Abstract Alkalinity is a key regulator of carbon dioxide (CO2 ${\text{CO}}_{2}$) dynamics in freshwater systems, influencing both dissolved inorganic carbon speciation and the buffering capacity of water. Despite its importance, alkalinity in freshwater environments remains comparatively underexplored relative to ocean systems.

Allochthonous chemical cues drive predation by a top carnivore

Functional Ecology, Volume 40, Issue 6, Page 1698-1708, June 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Identifying the mechanisms by which mobile predators detect and select prey remains a central challenge in sensory biology and functional ecology. This study provides the first direct evidence that chemical cues associated with allochthonous organic matter (e.g.

Changes in DOM Quality Determine Prokaryotic Activities and Extracellular Release in the NW Mediterranean Sea: An Experimental Approach

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Changes in DOM composition influence prokaryotic species growth in the Mediterranean Sea, shaping their metabolic responses and organic matter processing. In our study, higher DOP consumption and alkaline phosphatase activity led to the accumulation of recalcitrant DOM, highlighting how microbial community shifts drive distinct pathways in carbon ...

The Elbe Estuary Microbiome Shifts With Salinity and Discharge and Depends on Fresh Organic Matter and Nutrient Availability

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Microbial diversity within the Elbe Estuary was found to be more strongly governed by seasonal variability, salinity, and discharge than by spatial heterogeneity. Oligohaline regions sustain high diversity, while nutrient and redox conditions drive functional shifts.
