Taylor KT, Maxwell BD, Pauchard A, Nunez MA, Peltzer DA, Terwei A, Rew LJ. 2015. Drivers of plant invasion vary globally: evidence from pine invasions within six ecoregions. Global Ecology and Biogeography. 25(1):96-106
Aim: To determine biotic and abiotic controls on pine invasion globally within six ecoregions that include both introduced and native ranges. Locations: Río Negro province, Argentina; Aysén and Araucanía regions, Chile; South Island (two ecoregions), New Zealand; Greater Yellowstone ecosystem, USA. Methods: We quantified tree abundance and size across invasion fronts of the widespread invasive tree species Pinus contorta at each of the nine sites, encompassing both the native and introduced range.We also determined the relative importance of propagule pressure, abiotic characteristics and biotic factors for invasion success. Finally, key plant population metrics such as individual tree growth rates and reproductive effort were compared between native and introduced ranges.
