Plant colonization of actively sorted stone stripes in the subantarctic
Three grasses (Phleum alpinum L., Deschampsia antarctica Desv., Festuca contracta T. Kirk) and one perennial herb (Acaena tenera Alboff) are the earliest important colonizers of small-scale sorted stone stripes in fellfield areas on South Georgia. Survival potential differs considerably between the...
