Acute and Chronic Toxicity of Sediments Containing Platinum and Palladium on Freshwater Benthic Organisms Chironomus riparius and Hyalella azteca

Journal of Applied Toxicology, Volume 46, Issue 4, Page 1151-1163, April 2026.
ABSTRACT The expanding demand for platinum group elements (PGEs) in industrial and medical applications has led to their increasing accumulation in aquatic sediments. However, their ecological impacts remain poorly understood, particularly for sediment‐dwelling invertebrates. This study assessed the toxicity of platinum (Pt) and palladium (Pd) across a

Signatures of Wild Animal Life in Earth's Landscapes

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.
Abstract Animals shape Earth surface processes and landforms by displacing Earth surface materials and by making them more or less susceptible to geophysical processes. Despite increased recognition of the global significance of animal landscape “signatures”, analysis of their magnitude and generality has not been possible until now.

Integrating Satellite Data Into Meso‐Scale Habitat Modeling for Non‐Perennial Rivers and Streams

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract Non‐perennial rivers and streams (NPRs) are widespread and projected to become more common, yet effective tools for their characterization and management remain limited. This study introduces a novel approach to assess aquatic habitat availability in NPRs, applied to a regulated reach of the Sangone River (Northern Italy).
