Testing the 'addition and persistence model' of invertebrate succession in a subalpine glacier-foreland chronosequence: F?bergst?lsbreen, southern Norway

Invertebrate primary succession is investigated across a chronosequence in the subalpine (birch woodland) zone at Fåbergstølsbreen using pitfall traps. Presence and abundance of taxa, functional groups and communities are examined using a geo-ecological approach including mapping, graphical analysis, two-way indicator species analysis (TWINSPAN) and non-metric multidimensional scaling (NMS). Twenty-nine of the 67 recorded taxa, and 14 of the 37 epigeal (surface active) taxa colonize terrain deglacierized for
