Impact of climate change factors on the clonal sedge Carex bigelown: implications for population growth and vegetative spread
Hypothesized life‐cycle responses to climate change for the arctic, clonal perennial Carex bigelown are constructed using a range of earlier observations and experiments together with new information from monitoring and an environmental perturbation study These data suggest, that under current clima...
