Once upon a time in the far south: Influence of local drivers and functional traits on plant invasion in the harsh sub‐Antarctic islands
Abstract Aim Here, we aim to: (a) investigate the local effect of environmental and anthropogenic factors on alien plant invasion in sub‐Antarctic islands; and (b) explore whether and how functional traits affect alien species dependence on anthropogenic factors in these environments. Location Posse...

Methods Single‐species distribution models were used to explore the effect of high‐resolution topoclimatic and human‐related variables on the occurrence of six alien plants colonizing French sub‐Antarctic islands.

Differences in the influence of human‐related variables on the occurrence of the alien species were mostly related to their life history, plant height and residence time, with perennial and low‐statured species introduced earlier appearing less dependent on human‐induced dispersal and disturbance. Conclusions We conclude that both topoclimatic and anthropogenic factors affect plant invasion on sub‐Antarctic islands. Specifically, species predicted to occur close to their introduction sites appear much more dependent on human presence and activity, potentially due to the lack of key functional traits allowing them to spread successfully across Possession Island under the harsh sub‐Antarctic climate.
