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

Making gas diffusivity explicit in no‐till N2O interpretation

open access: yesAgricultural &Environmental Letters, Volume 11, Issue 2, December 2026.
Abstract No‐till can conserve soil and store carbon, yet its effects on N2O emissions remain inconsistent. Soil gas diffusivity regulates O2 supply, N2O production and reduction, and the N2O/(N2O + N2) product ratio, but this control is not always explicit when no‐till outcomes are interpreted from surface fluxes alone.

Livelihood Heterogeneity and Adoption of Combine Harvesters Under Flood Risk: Evidence From the Wetland Areas of Bangladesh

open access: yesClimate Resilience and Sustainability, Volume 5, Issue 2, December 2026.
Livelihood heterogeneity explains uneven combine harvester adoption in haor wetlands. PCA–cluster analysis identifies four farmer typologies shaping mechanization pathways. Adoption is highest among educated and networked land‐rich farmers, lowest among traditionalists.

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.

Fish Assemblages in an Urbanized Neotropical Basin: Influence of Environmental Factors Across Dry and Rainy Periods

open access: yesInternational Review of Hydrobiology, Volume 111, Issue 2, December 2026.
ABSTRACT This study investigated the effects of season and environmental disturbances on fish communities in neotropical rivers of the Sorocaba basin, a Sub‐Basin of the Paraná River in Southeast Brazil, based on sampling 1196 individuals from 49 species, including two non‐native and one threatened with extinction.
