Catchment Influences on Carbon Stable Isotope Variation in Trout; Might It Be Methane?

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Trout stable carbon isotope values vary significantly and appear to relate to catchment characteristics. Low carbon stable isotope values are linked to catchments with low drainage soil and high cover of pasture land use. This is likely to be linked to high levels of methane‐derived carbon entering the stream food web.

Water Quality Affects Water Source Allocation and Competition Between Sectors Globally

open access: yesEarth's Future, Volume 14, Issue 5, May 2026.
Abstract Human activities, including domestic water use, agriculture, and energy generation, cause increasing challenges in meeting water demands, not only due to water shortages, but also poor water quality. Nevertheless, there remains limited understanding of how water quality influences the allocation of water per source across different sectors at ...

Recent Changes and Variability of Suspended Particulate Matter in European and Mediterranean Coastal Waters Inferred From OLCI Data

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 5, May 2026.
Abstract Suspended Particulate Matter (SPM) plays a central role in coastal marine ecosystems, influencing light availability, primary production, and transport of sediments, nutrients, and pollutants. Monitoring its variability is essential for understanding the impacts of both natural and anthropogenic pressures on coastal regions.

Multi‐Scale Drivers of Food‐Water‐Energy Related Ecosystem Services in the Context of Land Degradation: Insights From the Beijing‐Tianjin‐Hebei Agglomeration

open access: yesLand Degradation &Development, Volume 37, Issue 6, Page 2058-2083, 15 April 2026.
ABSTRACT Land degradation poses significant challenges to maintaining food–water–energy (FWE) security, particularly in rapidly urbanizing regions. The ecosystem services (ES) related to FWE are critical for sustainable regional development. Yet, rapid urbanization in the Beijing–Tianjin–Hebei region has altered land use and ecological patterns ...
