Warming impacts potential germination of non-native plants on the Antarctic Peninsula
Abstract The Antarctic Peninsula is under pressure from non-native plants and this risk is expected to increase under climate warming. Establishment and subsequent range expansion of non-native plants depend in part on germination ability under Antarctic conditions, but quantifying these processes h...
