Using species attributes to characterize late‐glacial and early‐Holocene environments at Kråkenes, western Norway
Abstract Aim We aim to use species attributes such as distributions and indicator values to reconstruct past biomes, environment, and temperatures from detailed plant‐macrofossil data covering the late glacial to the early Holocene (ca. 14–9 ka). Location Kråkenes, western Norway. Methods We applied...
