Dispersal of moss propagules on Signy Island, maritime Antarctic
Aerobiological studies were conducted for >1 year using arrays of rotorod samplers at three sites on Signy Island, South Orkney Islands, maritime Antarctic. Spores of five bryophyte taxa were identified, all of which are known to be widely distributed and fruit frequently on the island. Spore siz...
