Anna Kellner🌲🌻 @annakellner.bsky.social · 18/08/2025Key questions: ❓Does pine marten recolonisation increase owl nest failure? ❓Do voles buffer this risk (via APH)? ❓Is there evidence of spatial or temporal refugia from predation? We combined long-term nest records with pine marten occupancy data + artificial nest experiments. 100
