Journal of Fish Biology, EarlyView.Abstract Point‐abundance sampling by electric fishing (PASE) was compared with single‐pass (DF1) and triple‐pass depletion sampling (DF3) electric fishing on the same reaches of four headwater streams sampled over multiple years in the Ribble catchment, UK. Juvenile salmonids, mostly brown trout Salmo trutta with some Atlantic salmon S.

Restoration Ecology, EarlyView.Abstract Introduction Over 44% of European lakes fail to meet ecological quality standards, prompting substantial investment in lake restoration to achieve good ecological status. Unfortunately, effects are often short‐lived due to persistent internal phosphorus (P) loading and strong cyprinid‐driven bottom‐up control, which limits water quality ...

Re-Establishment Techniques and Transplantations of Charophytes to Support Threatened Species
Plants, 2021 Re-establishment of submerged macrophytes and especially charophyte vegetation is a common aim in lake management. If revegetation does not happen spontaneously, transplantations may be a suitable option.

Plant-Environment Interactions, Volume 7, Issue 5, October 2026.ABSTRACT Macrophytes are vulnerable to various factors in their natural ecosystems, including climatic, ecological, and anthropogenic changes. This study aims to document how these factors influence floristic composition. Four sites were investigated in the Boeny Region of northwest Madagascar: Ambatoboeny, Marovoay, Ankarafantsika National Park, and ...

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.Abstract Kettle‐holes are small but biogeochemically active landscape elements that integrate terrestrial inputs and influence carbon and nitrogen cycling. However, the stability and sources of organic matter (OM) in kettle‐hole sediments remain poorly understood.

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 9, September 2026.ABSTRACT Geodiversity refers to the heterogeneity of abiotic characteristics in nature, and in freshwater ecosystems, it mostly mirrors the diversity of hydro‐geomorphological features in inland waters. Although several scholars have highlighted that geodiversity contributes to habitat formation and influences biodiversity and ecological processes, it ...

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 9, September 2026.ABSTRACT Environmental integrity is vital for the long‐term preservation of freshwater biodiversity, which is currently among the most threatened on Earth due to anthropogenic pressures such as dam construction. The present study investigated the temporal responses of ostracod communities over 8 years (2017–2024) in the Upper Paraná River floodplain ...

Ecology and Evolution, 2022 Due to climate change and increasing anthropogenic activities, lakes are disturbed frequently, usually by press (e.g., diffused pollution, rising temperatures) or pulse (e.g., storms, rainfall, pollution events) disturbances.
