Re-focusing sampling, design and experimental methods to assess rapid evolution by non-native plant speciesNARA Subscribed
Evolution can occur over contemporary timescales, which may be crucial for the invasive success of non-native plant species. Many studies have shown rapid evolution by comparing native and non-native populations in common gardens. However, our understanding of the mechanisms underpinning rapid evolution is still incomplete. Here, we identify the progress, applications, and limitations of studies on rapid evolution of non-nativ...
The EICA is dead? Long live the EICA !NARA Subscribed
An important hypothesis for how plants respond to introduction to new ranges is the evolution of increased competitive ability (EICA). EICA predicts that biogeographical release from natural enemies initiates a trade‐off in which exotic species in non‐native ranges become larger and more competitive, but invest less in consumer defences, relative to populations in native ranges. This trade‐off is exceptionally complex because...
Solidago gigantea plants from nonnative ranges compensate more in response to damage than plants from the native rangeNARA Subscribed
Resistance and tolerance are two ways that plants cope with herbivory. Tolerance, the ability of a plant to regrow or reproduce after being consumed, has been studied less than resistance, but this trait varies widely among species and has considerable potential to affect the ecology of plant species. One particular aspect of tolerance, compensatory responses, can evolve rapidly in plant species; providing insight into interac...
Alpine cushion plants inhibit the loss of phylogenetic diversity in severe environmentsNARA Subscribed
Biotic interactions can shape phylogenetic community structure (PCS). However, we do not know how the asymmetric effects of foundation species on communities extend to effects on PCS. We assessed PCS of alpine plant communities around the world, both within cushion plant foundation species and adjacent open ground, and compared the effects of foundation species and climate on alpha (within‐microsite), beta (between open and cu...
