Data from: Syndromes in suites of correlated traits suggest multiple mechanisms facilitating invasion in a plant range-expander

Various mechanisms can facilitate the success of plant invasions simultaneously, but may be difficult to disentangle. We compared plants of the range-expanding species Bunias orientalis from populations of native, invasive and exotic, not yet invasive origin in a field common garden over two years. Plants were grown under two nitrate-regimes and multiple traits regarding growth, defence, antagonist loads and reproduction were measured. We used a rank-based clustering approach to assign correlated traits to distinct suites. These suites were analysed for "syndromes" that are expressed as a function of population origin and/or fertilisation treatment and might represent different invasion mechanisms. Indeed, distinct suites of traits were differentially affected by these factors. Our results suggest that different pre-adaptation properties, such as certain growth characteristics and intraspecific chemical variation, as well as post-introduction adaptations to antagonists and resource availability in novel habitats are candidate mechanisms that facilitate the success of invasive B. orientalis in parallel. We conclude that rank-based clustering is a robust and expedient approach to integrate multiple traits for elucidating invasion syndromes within individual species. Studying a multitude of traits at different life-history and establishment stages of plants grown under distinct resource treatments reveals species-specific trade-offs and resource sinks and simplifies the interpretation of single trait functions for plant invasiveness.

Data for: Testing an invasion mechanism for Eucalyptus globulus: is there evidence of allelopathy?

Premise of study- Sparse understory communities, in association with non-native tree species, are often attributed to allelopathy, the chemical inhibition of one plant by another. However, allelopathy is a difficult ecological phenomenon to demonstrate with many studies showing conflicting results. Eucalyptus globulus, a native tree to Australia, is one of the most widely planted trees around the world. Sparse understories are common beneath E. globulusplantations and are often attributed to allelopathy, but the ecological impacts of E. globuluson native plant communities are poorly understood. Methods -To assess allelopathy as a mechanism of understory inhibition, we tested volatile- and water-soluble leaf extracts on seed germination of California native plants. We also quantified germination rates and early seedling growth of native plants grown in soil from E. globulusplantations versus soil from an adjacent native plant community. Key results- Volatile compounds from E. globulusdid not significantly reduce germination for any species. Inhibition from water-soluble E. globuluscompounds was comparable to that of a native tree, Quercus agrifolia (10%).Eucalyptus globulussoil supported germination and early seedling growth of native species equal to or better than coastal scrub soil, although species responses were variable. Conclusions- In contrast to previous studies, our results fail to support the hypothesis that E. globuluschemically inhibits germination of native species. California native plants germinate and grow well in soils from E. globulusplantations, which may have significant implications for management and restoration of land historically occupied by E. globulusplantations.

Importance of invasion mechanisms varies with abiotic context and plant invader growth form

1. Many invasion hypotheses propose biotic interactions as the main mechanism to explain non-native species' success. Despite the evidence that the strength of biotic interactions varies with abiotic context, it remains unclear whether the importance of the different mechanisms proposed to explain invasion predictably varies with abiotic context and whether this variation is consistent across different growth forms. 2. We reviewed studies at a global scale to evaluate whether evapotranspiration, latitude, precipitation, and temperature influence the importance of disturbance, enemy release, facilitation, and novel weapons mechanisms to explain non-native plant invasions. In total, we calculated 171 effect sizes for ~300 non-native plant species covering a wide range of environmental conditions and growth forms. 3. Environmental context and plant growth form influenced the role played by each invasion mechanism. The importance of disturbance in facilitating invasion exhibited a quadratic relationship with latitude and temperature and decreased with increasing precipitation. In mixed communities and trees, disturbance was mediated by either evapotranspiration, latitude, precipitation, or temperature. Enemy release exhibited a quadratic relationship with evapotranspiration, latitude, and precipitation, and was positively related to temperature. The importance of enemy release was also contingent on growth form and was highly context-dependent, enemy release responses for grasses, and trees were modulated by either evapotranspiration, latitude, precipitation, or temperature. The importance of facilitation decreased with increasing temperature. In forbs, facilitation decreased with evapotranspiration and temperature. The importance of novel weapons was more strongly confirmed for studies conducted at lower evapotranspiration, precipitation, and higher latitudes, and exhibited a quadratic relationship with temperature. 4. Synthesis. Our results show that environmental conditions not only filter non-native species depending on physiological tolerances but may also influence the importance of invasion mechanisms.
