Winter photosynthesis of evergreen broadleaf trees from a montane cloud forest in subtropical China

Winter photosynthesis of trees is well studied for boreal, Mediterranean, and some temperate forests, while little is known about the forests from tropical-subtropical transition zones and subtropical areas. Evergreen broadleaf trees dominate the forests from elevation 1,000 to 2,600 m in the subtro...
