+5K warming scenario for the two key species Androsace alpina (nival zone) and Carex curvula (alpine zone). Low (cyan), moderate (yellow), high (magenta) species cover.
Androsace alpina (Primulaceae): nowadays it is
widely distributed over the whole upper alpine and nival zone of
Schrankogel, but - as character species of the nival scree plant
communities - with a tendency to higher cover values (magenta pixels) in
the upper areas.
During the warming process, the model suggests a loss of abundance in
the lower areas and decreasing cover values in the upper areas.
This is most pronounced at moderate slope situations (e.g., the wide
southwestern slope) where sward-species have good
opportunities to migrate upwards. Only in specific topographic
situations, A. alpina will persist with higher cover.
Carex curvula (Cyperaceae): this species shows a complemenatry distribution pattern, compared to Androsace alpina.
The key-stone species of the alpine swards keeps away from habitats with too much environmental pressure,
either from snow, scree, or rockfall, and, therefore, prefers the safest sites in the area, which are the
southeast exposed, midslope situations below the major ridges. It will expand its area by moving upwards
along these stable ridges. With 5K warming, most of the today's nival zone will be covered by alpine grassland.
