Quantifying the seed bank of an invasive grass in the sub-Antarctic: seed density, depth, persistence and viability
A native to Europe, 'Poa annua' now has a cosmopolitan distribution and is invasive in the sub- Antarctic. As a major weed in temperate turf, there has been considerable investment in research of the species, but little is known about its ecology in the sub- Antarctic, particularly its rep...
