Redox‐Induced Transformations of Iron Oxides Enhance Soil Organic Carbon Stabilization in an Estuarine Soil

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 7, July 2026.
Abstract We investigated temporal changes in operational Fe pools and their association with soil organic carbon (SOC) fractions in an estuarine soil affected by the deposition of iron‐rich mine tailings over 6 years in Southeast Brazil. Sequential Fe extractions revealed a 56% decrease in Fe extracted with citrate–bicarbonate–dithionite alongside a 50%

A quantitative analysis to detect mass mortality events (wrecks) in Procellariiformes

Journal of Applied Ecology, Volume 63, Issue 7, July 2026.
Our study provides the first systematic assessment of seabird mass mortality events in the South Atlantic and introduces a transferable statistical framework for detecting MMEs in other taxa and regions lacking baseline mortality information. By identifying recurrent temporal anomalies, high‐risk areas and vulnerable species, we could establish ...

ORCHESTRATING DIFFERENCE AND SIMILARITY: Black Fungibility, and the Spatial Redrawing of Racial Categories in Spanish Colonial Morocco, Sahara and Guinea

International Journal of Urban and Regional Research, Volume 50, Issue 4, Page 960-981, July 2026.
Abstract In this article I dissect the spatial strategies through which the Spanish attempted to orchestrate both racial difference and similarity in the African colonies of Morocco, Western Sahara and Equatorial Guinea during the first half of the twentieth century.

Trophic Redundancy and the Hidden Dietary Overlap Between Native and Invasive Stream Fishes

Ecology of Freshwater Fish, Volume 35, Issue 3, July 2026.
ABSTRACT Biological invasions introduce non‐native species into natural ecosystems, often reshaping localcommunities and altering trophic interactions. In freshwater environments, such invasions can intensify resource use and threaten native fish diversity.

Challenges and Advances Driving Studies on Aquatic Insects of the Order Coleoptera

Freshwater Biology, Volume 71, Issue 7, July 2026.
ABSTRACT Aquatic beetles (Coleoptera) are known for their high taxonomic and ecological diversity and their sensitivity to environmental changes, making them key bioindicators in ecological assessments. However, numerous knowledge gaps persist globally.
