Fire enhances the ‘competition-free’ space of an invader shrub: Rosa rubiginosa in northwestern Patagonia

摘要: Fire can influence reproductive phenology of plants, enhancing the rate many species. Disturbances such as fire promote proliferation exotic species in native plant communities. In this study we analyze effect on three (a shrub: Berberis buxifolia and two small trees: Maytenus boaria Schinus patagonicus) an shrub (Rosa rubiginosa). Flowering fruiting was monitored neighbouring burned unburned forests. The shrubs flowered fruited both sites, but trees did so only site. There is no overlapping flowering phenophases between natives Therefore, they do not compete resource offering to pollinators seed dispersers. Consequently, R. rubiginosa has a ‘competition-free’ space enhanced by fire, from perspective.
