Response to simulated climatic change in an alpine and subarctic pollen‐risk strategist, Silene acaulis
The aim of this study was to test if early flowering species respond with increased seed production to climate warming as is predicted for late‐flowering seed‐risk strategists. Experimental climate warming of about 3°C was applied to two populations of the cushion‐forming plant Silene acaulis (L.) J...
