Kelp‐boulder transplants for habitat restoration

Restoration Ecology, EarlyView.
Abstract Introduction Degraded habitats present a major barrier to the survival and recovery of threatened marine species, particularly where structural or biogenic complexity has been lost, and natural regeneration ability is uncertain. Despite growing interest in habitat restoration, techniques rarely deliver rapid improvements at the necessary ...

Colonisation History of Freshwater Snails Across the Atlantic and Mediterranean Islands: Insights From Mercuria (Littorinimorpha, Hydrobiidae)

Zoologica Scripta, EarlyView.
ABSTRACT Islands harbour unique biodiversity, and depending on their geological origin, they have fundamentally different colonisation histories: continental islands may contain relict faunas shaped by vicariance and sporadic gene flow, whereas oceanic islands must have been colonised across open seas, often through long‐distance dispersal events ...

Freshwater Biodiversity Research in Brazil: Trends from a Systematic Review and Topic Modeling

International Review of Hydrobiology, Volume 111, Issue 2, December 2026.
ABSTRACT Brazil is a megadiverse country that hosts six major biomes and a vast freshwater network. Despite this richness, research on freshwater biodiversity has been heterogeneous across regions, communities, and time, leaving significant knowledge gaps.

Invasive goldfish trigger a regime shift in experimental lake ecosystems of varying trophic state. [PDF]

J Anim Ecol
The pet trade distributes exotic animals around the globe that enrich human lives. However, some pets become pests when released into the wild. This study provides experimental evidence that goldfish will negatively affect native freshwater organisms and ecosystems.

From Indicator to Prediction: Five Decades of Biochemical Oxygen Demand Research in Tropical Freshwaters

World Water Policy, Volume 12, Issue 4, November 2026.
ABSTRACT Biochemical oxygen demand (BOD) remains a core indicator of organic pollution in freshwater monitoring, but its role in water policy and practice is changing as water‐quality assessment moves toward predictive, integrative, and decision‐support approaches.

The Colonization of Newly Built Fishponds by the Macroinvertebrate Assemblages

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2016
The succession of standing waters by aquatic macroinvertebrates is a present and insufficiently surveyed topic. This study is addressed to the issue of colonisation of newly created small standing waters.

Habitat Preferences and Distribution of Ephemera orientalis (Ephemeroptera: Ephemeridae) in the Hangang River, South Korea

Entomological Research, Volume 56, Issue 10, October 2026.
ABSTRACT This study characterized the spatial distribution patterns and habitat preference of Ephemera orientalis larvae in the Hangang River based on four surveys conducted in April, June, August, and October 2024. Field surveys were conducted at 10 sites along a 24 km reach, with five cross‐sectional sampling points per site.
