Linking Abundance and Activity of Ammonia‐Oxidising Bacteria and Archaea in an Agriculturally Impacted First‐Order Stream

Environmental Microbiology, Volume 28, Issue 7, July 2026.
Ammonia‐oxidising archaea (AOA) and bacteria (AOB) coexist in streambed sediments, but their contributions to nitrification remain unresolved. Using field sampling, sequencing, qPCR, microcosm incubations and modelling, we show that AOB dominated nitrification in streambed sediments despite lower abundance, emphasizing the importance of distinguishing ...

Free‐living Black‐tailed Godwits maintain constant intake rates across varying grassland habitat conditions by adjusting their foraging behaviour

Ibis, Volume 168, Issue 3, Page 876-889, July 2026.
Free‐living birds need to acquire enough food to fulfil their energetic needs, which may require more effort in habitats with less favourable conditions. Therefore, to maintain their necessary energy intake, birds need to adjust their foraging behaviour in response to varying habitat conditions.

Effect of varying water content and applied voltage on the performance of electroosmotic dewatering [PDF]

E3S Web of Conferences
Electroosmotic (EO) dewatering is a technology that may be employed for the treatment of fine-grained soils with undesirable geotechnical characteristics, such as high compressibility and low undrained shear strengths.

Effect of Turbulent Fluctuation on Settling Behavior of Dredged Slurry in Sheared Condition

KSCE Journal of Civil Engineering, 2021
For the land shortage problem upon the city development in coastal areas, it is of great importance to improve the overall understanding of the settlement behavior of dredged slurry and determine the required site water storage capacity as well as the mechanical properties of the newly formed dredged slurry.

Sediment addition to address tidal marsh elevation deficits caused by farm impoundments: a Delaware Bay, New Jersey, United States case study

Restoration Ecology, Volume 34, Issue 5, July 2026.
Abstract Introduction Dredge material use is emerging as an important technique for restoring marshes threatened by historic mismanagement and sea‐level rise, yet optimal methods to maximize ecological benefit remain under development. The Delaware Estuary is in urgent need of restoration, as historic agricultural conversion caused substantial and ...

INFLUENCE OF CURING STRESS ON THE PULL-OUT BEHAVIOR OF A SINGLE GEOGRID RIB PLACED IN CEMENT-STABILIZED DREDGED SLURRY

Materiali in Tehnologije
Cement-stabilized dredged slurry, despite its enhanced compressive strength, lacks tensile strength, particularly with low cement contents. Geogrid reinforcement is usually used in high-fill projects to improve the soil tensile and shear strengths, but ...

Carbon Dioxide Uptake and Storage in Construction Materials: Mechanisms, Theoretical Capacity, and Global Potential

cScience, Volume 2, Issue 2, June 2026.
ABSTRACT The construction sector constitutes a major source of global carbon dioxide emissions, and cement production contributes substantially via fuel combustion and limestone decomposition. These challenges have encouraged the incorporation of carbon dioxide into construction materials through mineralization.

Impact of Elevated Suspended Sediment on the Physiology of the Temperate Sponge Suberites australiensis

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 2, June 2026.
Suspended sediment (SS) is a major stressor to coastal marine ecosystems worldwide, with SS loads expected to increase under future anthropogenic and climatic pressures. Sponges, as obligate filter feeders, are often assumed to be sensitive to elevated SS, yet responses vary widely among species, and little is known about physiological impacts of SS ...

Flocculation Treatment for Mitigating Clogging of Dredge Slurry Under Vacuum Preloading with Particle Image Velocimetry Analysis

Applied Sciences
To examine the effect of flocculation treatment on slurry clogging during vacuum preloading, this study conducted vacuum preloading model tests using lime, anionic polyacrylamide (APAM), and the dual use of polyaluminum chloride (PAC) and APAM in ...

Disentangling the Roles of Microbial Traits and Mineral Protection in Regulating Temperature Sensitivity of Soil Carbon Decomposition in Eroded and Depositional Agricultural Soils

Earth's Future, Volume 14, Issue 4, April 2026.
Abstract The temperature sensitivity of soil organic carbon decomposition (Q10) governs the fate of soil carbon under global warming. Although erosion redistributes soil carbon at scales comparable to the terrestrial carbon sink, how erosion reshapes Q10 across large regional scales remains elusive.
