Ice cover and seasonal variation shape eDNA detection in a southern high-latitude river

Key Points

• eDNA detection significantly varies due to changes in ice cover and seasonal conditions, impacting river monitoring efforts.
• The study indicates that both factors influence the amount of eDNA found, with notable changes throughout the seasons.
• Observational analysis across southern high-latitude rivers shows how environmental changes affect eDNA presence.
• These findings highlight the need for seasonal considerations in freshwater biodiversity assessments.
