Floral intra‐individual variation differs between morphs and is linked to pollen deposition in self‐incompatible distylous plants

open access: yesPlant Biology, EarlyView.
For most traits, floral intra‐individual variation was similar between morphs and populations with different pollinator guilds (bees and hummingbirds), potentially facilitating effective pollen transfer in distylous systems. Still, greater variation in corolla length increased pollen deposition in L‐morph flowers in the bee‐pollinated population ...

There Is Always a Bigger Fish. Determinants of Power Perceptions in Swiss Biodiversity Policy

open access: yesPolicy Studies Journal, EarlyView.
ABSTRACT The Advocacy Coalition Framework (ACF) views power as crucial in policy processes, but the nature of coalition power, its determinants, and how to empirically measure it remain understudied. In this article, we use a mixed method approach and social network analysis to explore power relationships in the biodiversity policy subsystem in ...

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

open access: yesZoologica 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 ...

Experimental Assessment of Epipelon Responses to Phosphorus Limitation in a Eutrophic Lake

open access: yesEcological Research, Volume 41, Issue 6, November 2026.
We evaluated the responses of epipelic algal and cyanobacterial communities to increasing phosphorus limitation in the water column under eutrophic conditions. Nitrogen enrichment increased the N:P ratio and intensified phosphorus limitation in the water column, promoting changes in community composition. The greater contribution of cyanobacteria (e.g.,
