Biogeographic effects on early establishment of an invasive alien plant

Premise of the study: Biotic resistance is often studied in the context of how interactions between native biota and invading species influence the success of those invaders. Seldom, however, is the strength of “resistance” compared biogeographically, where the ability of a species to impede invader establishment is contrasted between an invader’s native and introduced recipient...

Origin matters: diversity affects the performance of alien invasive species but not of native species

Sun, Yan ; Müller-Schärer, Heinz ; Maron, John L. ; Schaffner, Urs

In: The American Naturalist, 2015, vol. 185, no. 6, p. 725–736

At local scales, it has often been found that invasibility decreases with increasing resident plant diversity. However, whether resident community diversity similarly resists invasion by alien versus native species is seldom studied. We examined this issue by invading constructed native plant assemblages that varied in species and functional richness with invasive alien or native Asteraceae...

Effects of soil fungi, disturbance and propagule pressure on exotic plant recruitment and establishment at home and abroad

Biogeographic experiments that test how multiple interacting factors influence exotic plant abundance in their home and recipient communities are remarkably rare. We examined the effects of soil fungi, disturbance and propagule pressure on seed germination, seedling recruitment and adult plant establishment of the invasive Centaurea stoebe in its native European and non-native North American...
