Losers and winners: responses of grassland arthropods to land‐use components

Oikos, Volume 2026, Issue 2, February 2026.
Intensified land‐use in grasslands reduces biodiversity, particularly affecting arthropod populations. However, responses of individual species vary depending on their ecological traits and habitat requirements. Some species may tolerate or even benefit from intensive land‐use, while others, particularly specialists or those with narrow niches, are ...

Towards Functional Fertilisers: Feed Composition Shapes Microbial Community Structure and Viability in Black Soldier Fly (Hermetia illucens) Frass

Environmental Microbiology, Volume 28, Issue 2, February 2026.
Frass derived from black soldier fly larvae reared on various industrial side streams was investigated in both untreated and hygienised (1 h at 70°C) condition. Hygienisation efficacy was evaluated by determination of viable microbial counts, using both selective and non‐selective cultivation media.

Prediction of slurry operating temperature and biogas production rate using ambient temperature forecast as input parameter for underground brick-built biogas digesters

Cogent Engineering, 2022
The operational temperature of the biogas digester is the most critical parameter for optimum biogas production. Most household digesters are operated at ambient temperatures throughout the year.

Agricultural System Resilience of Industrial Hemp: An Exploratory Value Web Analysis in the Swabian Alb

GCB Bioenergy, Volume 18, Issue 2, February 2026.
This study assessed the industrial hemp value web resilience in the Swabian Alb, Southern Germany, where regional implementation remains limited despite hemp's bioeconomy potential. Using an indicator framework and stakeholder interviews, the research found the small, fluctuating cultivation area (e.g., 25 ha in 2024) focuses on hemp seed valorisation;

Sulfur‐Enhanced Performance and Durability of SrFe0.75Mo0.25O3−δ/Ce0.9Gd0.1O2−δ Fuel Electrodes for Solid Oxide Fuel Cell

Advanced Energy and Sustainability Research, Volume 7, Issue 1, January 2026.
Conventional Ni‐cermet fuel electrodes in solid oxide fuel cells (SOFC) suffer from poor tolerance toward sulfur impurities. Here, Ni‐free perovskite‐based SrFe0.75Mo0.25O3−δ (SFM)/Ce0.9Gd0.1O2−δ (CGO) fuel electrodes are investigated with and without trace hydrogen sulfide addition.
