Watershed land cover predicts the abundance of macroplastic and other anthropogenic litter in streams

open access: yesLimnology and Oceanography, Volume 71, Issue 6, June 2026.
Macroplastic and other types of macroscopic anthropogenic litter (AL; trash, particles > 5 mm) are pervasive across ecosystems, persistent in the environment, increasing in abundance, and can degrade into microplastics (particles < 5 mm). Rivers retain and transform AL prior to export downstream, but improved predictions of AL distribution and movement

Inter‐Annual Variation in Alpha and Beta Diversity of Benthic Macroinvertebrate Communities in Agricultural Ditches

open access: yesRiver Research and Applications, Volume 42, Issue 5, Page 997-1010, June 2026.
ABSTRACT Ditches are essential elements of the agricultural landscape because of their role as habitat or refuge for aquatic species, especially in homogenized and intensively cultivated areas. However, data on the biodiversity associated with agricultural ditches, and its variation over time, are underrepresented in ecological research.
