Increased Phenotypic Plasticity to Climate May Have Boosted the Invasion Success of Polyploid Centaurea stoebe
Phenotypic plasticity may allow organisms to cope with altered environmental conditions as e.g. after the introduction into a new range. In particular polyploid organisms, containing more than two sets of chromosomes, may show high levels of plasticity, which could in turn increase their environmental tolerance and invasiveness. Here, we studied the role of phenotypic plasticity in the invasion...
متن کاملFungal endophytes in spotted knapweed influence its competitive interactions
Fungal endophytes in spotted knapweed influence its competitive interactions. Abstract Fungal symbionts are often overlooked in studies of plant invasion. Nevertheless, their role could be essential to the competitive success of the invader. We studied fungal endophytes in the widespread invasive Centaurea stoebe (common knapweed). A preliminary experiment showed that endophytes in roots of C. ...
متن کاملHybridization and invasion: an experimental test with diffuse knapweed (Centaurea diffusa Lam.)
A number of studies have suggested a link between hybridization and invasion. In this study, we experimentally test the potential for hybridization to influence invasion through a greenhouse common garden study. Diffuse knapweed (DK) (Centaurea diffusa Lam.) was introduced to North America with admixture from spotted knapweed (SK) (Centaurea stoebe subsp. stoebe L.). Comparisons between North A...
متن کاملBiogeographic 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 community. MET...
متن کاملPlant invasions, generalist herbivores, and novel defense weapons.
One commonly accepted mechanism for biological invasions is that species, after introduction to a new region, leave behind their natural enemies and therefore increase in distribution and abundance. However, which enemies are escaped remains unclear. Escape from specialist invertebrate herbivores has been examined in detail, but despite the profound effects of generalist herbivores in natural c...
