Height and growth rings of Salix lanata ssp. richardsonii along the coastal temperature gradient of northern Alaska
Salix lanata ssp. richardsonii from open-tundra and streamside populations were studied at seven sites along a 100-km north–south transect following the Sagavanirktok River from the Alaskan arctic coast to the foothills of the Brooks Range. Mean July temperatures along this transect vary from 2.6 at...
