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 reproductive ecol...
