Development and Research Progress of the ‘Land‐Based Container + Ecological Pond’ Recirculating Aquaculture Model in China

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
This review systematically examines China's Land‐based Container + Ecological Pond (LCEP) recirculating aquaculture model. It synthesizes the system's development, technical principles, and research progress, highlighting its significant resource savings (>75% land, >90% water) and high‐density production capabilities. The analysis critically evaluates

Forest Disturbance Drives Changes in the Functional Traits of Soil Bacteria: A Metagenomic Study of Kauri (Agathis australis) Forest Ecosystems

Ecology and Evolution, Volume 16, Issue 4, April 2026.
This study reveals how ecological disturbances reshape the structure and function of soil bacterial communities in kauri forests, which are critical for ecosystem resilience. By linking disturbance regimes to shifts in bacterial diversity and functional capacity, it highlights the wider effects of ecosystem disturbance on soil ecological function ...

Evaluating Phosphorus Sorption and Desorption in Agricultural Wastewater Using Designer Biochar Pellets

Water Environment Research, Volume 98, Issue 4, April 2026.
This study evaluated the effectiveness of designer biochar pellets (DBPs) in adsorbing phosphorus from tile drain outflow and agricultural wastewater effluents, with performance varying depending on the effluent source. Results highlight the potential of biochar‐based filters for targeted phosphorus removal, providing a promising approach to reduce ...

Comparing the effects of temperature and C/N ratios on denitrification between point bar and straight channel sediments

Journal of Freshwater Ecology
The riverbed and riparian zone are the hotspots of nitrogen removal in rivers. Denitrification plays an important role in the process of nitrogen removal.

Long‐Term Reorganization of Ocean Nutrient Distribution

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract Nutrient availability is a major driver of ocean biodiversity and productivity, yet long‐term global changes remain poorly constrained. Using over 14 million nitrate and phosphate measurements collected between 1925 and 2025, we quantify long‐term trends in nutrient concentrations across ocean biomes and depths.

Bridging the Gap From Peat to Ponds: Terrestrial and Aquatic Greenhouse Gas Emissions in an Evolving Permafrost‐Associated Subarctic Peatland

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 4, April 2026.
Abstract Rapid permafrost thaw in peatlands transforms the subarctic landscape into a mosaic of ponds and peat soil, varying in moisture, carbon and nutrients, and time since thaw. As subarctic permafrost degrades, ponds emerge and mature and can gradually infill with Sphagnum peat.

Spatiotemporal Patterns of Nutrient Fluxes in an Agricultural Reservoir

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 2, April 2026.
ABSTRACT Reservoirs are vital tools for managing riverine water resources but also influence water quality through in‐lake nutrient (i.e., nitrogen [N] and phosphorus [P]) dynamics that affect downstream ecosystems. This study presents a multiscale spatiotemporal characterization of water quality in Carlyle Lake, an agriculturally impacted reservoir in

Development of a SWAT+ Model to Improve Conservation Practice Efficacy for Protecting Stream Health in Karst Pasturelands

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 2, April 2026.
ABSTRACT Placing appropriate conservation practices in critical source areas of pollutants can benefit stream health in karst environments susceptible to agricultural pollution. Watershed models, such as the Soil and Water Assessment Tool+ (SWAT+), can optimize both practice selection and placement across the landscape, but to our knowledge no studies ...

Groundwater Contributions to Daily Nitrogen and Phosphorus Loads and Implications for Prediction in Watersheds in South Korea

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 2, April 2026.
ABSTRACT Understanding watershed water quality dynamics is essential for sustainable management, yet accurate nutrient load prediction remains challenging under strong inter‐annual variability. To address this limitation, this study presents a hybrid modelling framework that integrates baseflow information into a machine‐learning structure to improve ...
