A numerical analysis of the mesoscale distribution patterns of vascular plants in the subarctic Kevo Nature Reserve, northern Finland
Different numerical techniques were used to detect and describe the major ecological‐biogeographical patterns of vascular plant distributions at the meso‐scale level in a subarctic region in Finland. The distribution patterns of 231 native taxa in 362 1 km 2 grid squares of the Kevo Nature Reserve w...
