- Association Ozone depletion contributed to increased regional summer wind speed.
- Association Wind speed explained 31.8% of variation in moss turf water content, which was negatively correlated with wind speed.
- Association Wind speed explained 37.4% of variation in photosystem II quantum yield, which was negatively correlated with wind speed.
- Association B. pseudotriquetrum increased xanthophyll cycle photoprotection under higher wind.
- Association C. purpureus xanthophyll cycle photoprotection decreased with higher turf water content.
- Association B. pseudotriquetrum xanthophyll cycle photoprotection decreased with higher turf water content.
- Observation The endemic S. antarctici did not show the wind and water-content photoprotection pattern.
- Mechanism The authors suggest stronger summer winds exacerbate desiccation of coastal East Antarctic moss communities.
- Mechanism The authors suggest wind-driven desiccation favors expansion of cosmopolitan mosses.
- Mechanism The authors suggest wind-driven desiccation displaces the endemic moss.
