Leaf traits and shoot performance of an evergreen shrub, Ledum palustre ssp. decumbens , in accordance with latitudinal change
Individual leaf traits, leaf age structure, and leaf dry mass of Ledum palustre ssp. decumbens were compared at three sites along a latitudinal gradient: temperate mountain (43°30′N), taiga (62°10′N), and arctic tundra (71°25′N). At the arctic site, L. palustre produced leaves having longer life-spa...
