Water Levels More than Earthworms Impact Rice Growth and Productivity: A Greenhouse Study

open access: yesAgronomy
Earthworms are highly active in Southeast Asian paddy fields, yet their activity is challenging to measure in flooded soils. Therefore, this study investigates the influence of the subaquatic earthworm Glyphidrilus papillatus (Michaelsen, 1896) on soil ...

Downcurrent variation in submarine channel‐fill architecture from the shelf to upper slope

open access: yesSedimentology, EarlyView.
ABSTRACT The transition between the shelf and the upper slope is often considered an area of sediment bypass, where steeper gradients increase flow velocities and maintain particles in suspension. In addition to transferring sediments into deeper basins, upper‐slope areas can also host channelised submarine deposits.

Microplastic Dynamics in Sediment Layers of Two Ramsar‐Designated Wetlands

open access: yesWater and Environment Journal, EarlyView.
ABSTRACT Little is known about the vertical and spatial dynamics of microplastics in relation to hydrology and land use, particularly in African context. This study aimed to assess the abundance, type, colour and vertical distribution of microplastics in sediment from two Ramsar‐designated wetlands, the Makuleke and Nylsvley. Sediment core samples were

Effects of Bioturbation by Earthworms on Litter Flammability in Young and Mature Afforested Stands

open access: yesFire
The quantity, quality, and accumulation rate of plant litter play a key role in forest floor flammability and, by extension, fire regimes. The varying foliage properties of different tree species also determine litter’s decomposition and its accumulation

The extent and significance of bioturbation on Cs-137 distributions in upland soils

open access: yes, 2001
Differences between measured 137Cs activity-depth profiles and idealised undisturbed profiles generated from an exponential model suggest that faunal turbation has redistributed 137Cs in mineral and organic upland soils in southern Scotland. Bioturbation

New ichnological findings in Hauterivian sandstones of Mountainous Adygeya

open access: yesИзвестия высших учебных заведений: Геология и разведка
Background. Trace fossils are highly informative objects for geological investigations. However, the information about their distribution in sedimentary settings lacks completeness.

Bioturbation: Some effects on remanent magnetization acquisition

open access: yes, 1984
A 1 mm layer of magnetite powder has been sprinkled into a 3 cm deep, 1 meter long trench in high bioturbation rate tidal flat sediments, Sapelo Island, Georgia (USA).

Sustained Livestock Grazing Enhances Soil Organic Carbon Storage in Sub‐Arctic Grassland

open access: yesGlobal Change Biology Communications, Volume 1, Issue 4, December 2026.
We studied long‐term effects of grazing cessation on 34 grassland and heathland sites in Iceland. Grazing cessation was associated with lower SOC, nitrogen and root carbon in the top 10 cm of soil providing evidence for enhanced SOC in grazed land, showing that grazing is a climate change mitigation strategy.

Freshwater Biodiversity Research in Brazil: Trends from a Systematic Review and Topic Modeling

open access: yesInternational Review of Hydrobiology, Volume 111, Issue 2, December 2026.
ABSTRACT Brazil is a megadiverse country that hosts six major biomes and a vast freshwater network. Despite this richness, research on freshwater biodiversity has been heterogeneous across regions, communities, and time, leaving significant knowledge gaps.
