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

Limnology 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

Oases of endemism: Regional aquifer desert springs serve as biodiversity hotspots preserving vulnerable endemic taxa in the Great Basin and Mojave Desert regions

Limnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract Spring ecosystems in arid regions often serve as crucial biodiversity hotspots by providing some of the only reliable sources of surface water. However, anthropogenic activities and climate change have severely degraded spring ecosystems worldwide, emphasizing the need for large‐scale multidisciplinary studies informing conservation efforts ...

A global assessment of abyssal–hadal vermiform lebensspuren: Functional consistency with depth

Limnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract Lebensspuren—sedimentary traces produced by benthic organisms—are widespread on deep‐sea floors but remain infrequently reported from abyssal (~ 3000–6000) and hadal (> 6000 m) environments. Here, we present the most comprehensive assessment of abyssal–hadal vermiform lebensspuren to date, spanning multiple ocean basins and reaching full‐ocean

A Tool for Prioritizing Gravel Augmentation Reaches for Sediment Starved Rivers

River Research and Applications, Volume 42, Issue 5, Page 1069-1082, June 2026.
ABSTRACT Gravel augmentation is a widely used restoration technique used to improve habitat below dams, including salmonids spawning habitat. However, gravel augmentation can be cost‐prohibitive, and it is often unclear which stream segments have the highest potential to benefit spawning salmonids.

Geomorphic Responses to Post‐Grazing Recovery and Stream Restoration in Semiarid Grassland Streams

River Research and Applications, Volume 42, Issue 5, Page 1083-1098, June 2026.
ABSTRACT Semiarid grassland streams are sensitive to land use, climate, extreme discharges, and internal geomorphic thresholds that drive episodic erosion. Rooted in a process‐based philosophy and commonly applied to historically wood‐rich, beaver‐modified systems, low‐tech process‐based restoration using structures is increasingly being extended to ...
