River Connectivity in Dammed Areas Studied Through Environmental DNA Metabarcoding at Community and Species Levels

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT The field of environmental DNA (eDNA) is rapidly expanding with established applications in biodiversity monitoring, rare species detection and ecological assessment. However, its potential to evaluate species connectivity in fragmented aquatic systems remains underexplored.

Environmental DNA (eDNA) and Field Surveys as Complementary Tools for the Biomonitoring of Amphibian Communities

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT Amphibians are facing large population declines as a result of both natural and anthropogenic threats. Reconstructing and understanding the composition and structure of amphibian communities is essential for developing effective monitoring and conservation strategies.

Ephemeropteran and Trichopteran Assemblages Vary Across a Subtropical Rainforest Altitudinal Gradient: Useful Indicators for Climate Change

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
This figure provides the elevation distribution of Trichoptera and Ephemeroptera across the elevational gradient and clearly shows how specific morphospecies can be used as indicators. ABSTRACT The subtropical rainforests of eastern Australia are expected to be greatly affected by climate change, with several studies predicting an upward shift in ...

Impacts of a Century‐Old Urban Dam on Water Quality and Habitat Composition, Flint River, Flint, MI

open access: yesRiver Research and Applications, Volume 42, Issue 2, Page 432-443, February 2026.
ABSTRACT Dams significantly influence river ecosystems worldwide, fragmenting habitats, altering sediment transport, and reducing biodiversity. Urban rivers are especially vulnerable, where dams compound stressors such as channelization, pollution, and degraded riparian zones. In response, dam removals are a growing restoration tool globally.

Making Waves: The Effects of Whitewater Parks on Fish Passage in Colorado

open access: yesRiver Research and Applications, Volume 42, Issue 2, Page 295-310, February 2026.
ABSTRACT Instream structures have fragmented riverine habitats throughout much of the world, including the Western USA. Whitewater parks (WWPs) are relatively new instream structures designed to create hydraulic waves for recreational boating and surfing by constricting flows into a steep chute or drop.
