Entomophily of the cloudberry ( Rubus chamaemorus)
Abstract Cloudberry ( Rubus chamaemorus L.), a dioecious perennial plant of boreal circumpolar distribution, is greatly prized for its berries. We crossed two treatments, pollinator exclusion and supplementary hand‐pollination, to determine i) the relative importance of insects as pollinators, ii) i...
