The Seasonal Rhythms of Coastal eDNA: Insights Into Biodiversity and Regional Detection Patterns
Environmental DNA, Volume 8, Issue 1, January–February 2026.Seasonal variation affects environmental DNA (eDNA) detection, yet its influence on species monitoring remains underexplored. This study examines eDNA detection windows across taxa, primers, and regions, finding that most species have short detection periods (1–2 months) that vary with taxonomy and primer choice. These results underscore the importance

Successful stocking of wild European perch in a reestablished lake with lasting effect over 10 years
Restoration Ecology, Volume 34, Issue 1, January 2026.Biological manipulation of fish compositions to enhance top‐down control of trophic webs is a common method for improving water and ecological quality in shallow eutrophic lakes, but it often fails. As an alternative to manually thinning unfavored fish stocks, piscivorous fish species can be released to suppress the recruitment of cyprinid fish ...

Aquaculture, Fish and Fisheries, Volume 5, Issue 6, December 2025.ABSTRACT Climate change is altering north‐temperate lake ecosystems through warming and increased aquatic macrophyte production. These changes have the potential to cause ecosystem shifts that challenge status quo fisheries management and require the adoption of new strategies to resist, accept, or direct such shifts.
