Assessment of Hyporheic Macroinvertebrate Biodiversity Within Gravel Bars Before and After Flooding: Comparison of Morphology, Bulk‐Sample, and eDNA Metabarcoding

Environmental DNA, Volume 8, Issue 5, September‐October 2026.
eDNA metabarcoding is generally consistent with morphology and bulk‐sample metabarcoding in revealing changes in hyporheic macroinvertebrate biodiversity influenced by flood and lateral locations of hyporheic zones.

Use of Invasive Rugulopteryx okamurae Beach Wrack as Habitat and Food by Talitrus saltator

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 8, August 2026.
ABSTRACT The introduction of non‐native algae into coastal waters has increased worldwide, causing a range of ecological and socio‐economic impacts. However, when stranded on beaches as wrack, these invasive algae can provide refuge and food for supralittoral organisms, potentially benefiting local fauna communities and beach functioning. In this study,

Enemy release: loss of parasites in invasive freshwater bivalves Sinanodonta woodiana and Corbicula fluminea

Ecography, Volume 2026, Issue 8, August 2026.
Invasive freshwater bivalves harm native species, ecosystems and biodiversity, and incur economic costs. The enemy release hypothesis posits that invasive species are released from enemies during the invasion process, giving them a competitive advantage in the new environment.

When natural disturbances and anthropogenic stressors interact, non‐perennial reaches become particularly vulnerable to global change: Insights from France

Journal of Applied Ecology, Volume 63, Issue 8, August 2026.
Our results show that functional redundancy provides a consistent indicator of anthropogenic impact across both perennial and non‐perennial rivers. We suggest that incorporating this metric into biomonitoring frameworks could improve the detection of ecological degradation in increasingly intermittent river networks, offering a more robust basis for ...

Long‐term reduction of invasive killer shrimp (Dikerogammarus villosus) density following removal of zebra mussel (Dreissena polymorpha) shells and coarse substrate on UK lake beds

Ecological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
Working with Citizen Scientists, researchers tested manual removal of coarse cobbles and zebra mussel shells from fine‐sediment lake beds to reduce invasive killer shrimp densities. Killer shrimp use these features for habitat, and after clearing them from 3 × 3 m sections of lakebed, killer shrimp densities were reduced by over 90% in these sections ...

Potential Impacts of Low Flows on Fish Foodscapes and Production in a Braided River

River Research and Applications, Volume 42, Issue 6, Page 1366-1382, July 2026.
ABSTRACT Changes in river discharge affect the physical composition and connectivity of habitats which, in turn, may shape the spatial distribution of fish food abundance, accessibility and quality—the ‘foodscape’—of river ecosystems. However, the influence of river flows on fish foodscapes has received very little attention from scientists. We studied
