Sedimentary lycopane/n‐C31 ratio as a proxy for bottom water hypoxia in coastal ocean

Limnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract Bottom‐water hypoxia on continental shelves is intensifying under climate change and eutrophication, yet long‐term records remain scarce. Here we show that the sedimentary lycopane/n‐C31 ratio reliably records bottom‐water oxygenation in the seasonally hypoxic Yangtze River Estuary.

Higher methanotroph abundance and bottom‐water methane in ponds with floating photovoltaic arrays

Limnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract Floating photovoltaic (FPV) arrays alter the methane (CH4) cycling dynamics of waterbodies on which they are deployed. Here, we investigated dissolved CH4 dynamics and associated CH4 cycling microbial communities (methanogens and methanotrophs) in the 2nd year of FPV deployment (70% aerial coverage) in experimental ponds.

The fate of methane in ponds: Drivers of production, storage, oxidation, and emissions

Limnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract Ponds are disproportionately large contributors to global carbon cycling, with substantial but variable emissions of methane (CH4) to the atmosphere relative to their global surface area. Efforts to upscale pond CH4 emissions have focused on broad‐scale correlates of emissions, yet mechanisms underlying the variability in emissions remain ...

The Microbiome as a Mirror: Distinguishing Healthy Individuals From Chronic Constipated Patients and Identifying Those With Hidden Psychiatric Burden

Microbiota Medicine Research, Volume 1, Issue 3, Page 91-106, September 2026.
Gut microbiota signatures distinguish chronic constipated patients from healthy individuals, supporting noninvasive diagnostic potential. Despite challenges in identifying psychiatric‐related comorbidities, microbial alterations, particularly in neurotransmitter and inflammatory pathways, lay the groundwork for future companion diagnostics and ...

Mechanistic role of biochar as a geobiochemical amendment: Mitigating abiotic stress and enhancing soil–plant interactions

Soil Science Society of America Journal, Volume 90, Issue 5, September/October 2026.
Abstract Abiotic stressors, including drought, salinity, and heavy metal contamination, pose escalating threats to global food security, challenges further exacerbated by climate change and progressive soil degradation. As a strategic geochemical amendment, biochar is increasingly proposed to enhance soil resilience and agricultural sustainability ...

Advancements and Challenges in Second‐ and Third‐Generation Biofuels: A Comparative Analysis of Lignocellulosic and Algal Feedstocks

Safety Science and Technology, Volume 1, Issue 3, September 2026.
ABSTRACT Advanced biofuels derived from nonfood biomass are increasingly recognized as strategic components of low‐carbon energy systems, particularly for sectors where direct electrification remains difficult. Second‐generation biofuels from lignocellulosic residues and third‐generation biofuels from algal and aquatic biomass offer complementary ...

Two‐Stage Anaerobic Digestion of Sugarcane Vinasse: A Bibliometric Analysis of Research Trends and Gaps

Environmental Quality Management, Volume 36, Issue 3, September 2026.
ABSTRACT Sugarcane vinasse, a by‐product of bioethanol production, poses a significant environmental challenge due to its high organic load and the large volumes generated. Anaerobic digestion (AD) has been widely explored as an alternative treatment, particularly in two‐stage configurations that can enhance methane recovery.
