1 1. The success of species invasions depends on multiple factors act-2 ing over the four invasion stages transport, colonisation, establish-3 ment, and landscape spread. Each of these stages is influenced simul-4 taneously by particular species traits and abiotic factors. While the 5 importance of many of these determinants has already been inves-6 tigated in relative isolation, they are rarely studied in combination 7 and even then mostly ignore the final phase, i.e., landscape spread. 8 2. Here we address this shortcoming by exploring the effect of both 9 species traits and abiotic factors on the success of invasions using an 10 individual-based mechanistic model, and relate those factors to the 11 stages of invasion. This approach enables us to explicitly control abi-12 otic factors (temperature as surrogate for productivity, disturbance 13 and propagule pressure) as well as to monitor whole-community trait 14 distributions of environmental adaptation, mass and dispersal abili-15 ties. We simulated introductions of plant individuals to an oceanic 16 island to assess which abiotic factors and species traits contribute to 17 invasion success.183. We found that the most influential factors were higher propagule 19 pressure and a particular set of traits. This invasion trait syndrome 20 was characterized by a relative similarity in functional traits of in-21 vasive species to natives, while invasives had on average higher en-22 vironmental tolerances, higher body mass and increased dispersal 23 abilities, i.e., were more generalist and dispersive. 24 4.

“…Huebner and Tobin (2006) found greater invasion of exotics on the more mesic, northeast-facing slopes in West Virginia, USA, as did Knüsel et al (2017) in abandoned chestnut orchards and coppice forests in southern Switzerland. Huebner et al (2018) found little difference in first-year survival of Ailanthus seedling transplants based on aspect (northeast-vs. southwest-facing), or management regime (single or repeated-burn sites were not different from control, shelterwood or diameter limit cut). In our models, the driest sites also were less likely to have Ailanthus present, likely because forest floor conditions and soil moisture are not as good for Ailanthus germination and establishment in those settings; perhaps also several native oaks and hickories are more competitive in those situations (Iverson et al 2017;Iverson et al 2018).…”

Predicting Ailanthus altissima presence across a managed forest landscape in southeast Ohio

Background: The negative impacts of the exotic tree, Ailanthus altissima (tree-of-heaven, stink tree), is spreading throughout much of the Eastern United States. When forests are disturbed, it can invade and expand quickly if seed sources are nearby. Methods: We conducted studies at the highly dissected Tar Hollow State Forest (THSF) in southeastern Ohio USA, where Ailanthus is widely distributed within the forest, harvests have been ongoing for decades, and prescribed fire had been applied to about a quarter of the study area. Our intention was to develop models to evaluate the relationship of Ailanthus presence to prescribed fire, harvesting activity, and other landscape characteristics, using this Ohio location as a case study. Field assessments of the demography of Ailanthus and other stand attributes (e.g., fire, harvesting, stand structure) were conducted on 267 sample plots on a 400-m grid throughout THSF, supplemented by identification of Ailanthus seed-sources via digital aerial sketch mapping during the dormant season. Statistical modeling tools Random Forest (RF), Classification and Regression Trees (CART), and Maxent were used to assess relationships among attributes, then model habitats suitable for Ailanthus presence. Results: In all, 41 variables were considered in the models, including variables related to management activities, soil characteristics, topography, and vegetation structure (derived from LiDAR). The most important predictor of Ailanthus presence was some measure of recent timber harvest, either mapped harvest history (CART) or LiDARderived canopy height (Maxent). Importantly, neither prescribed fire or soil variables appeared as important predictors of Ailanthus presence or absence in any of the models of the THSF. Conclusions: These modeling techniques provide tools and methodologies for assessing landscapes for Ailanthus invasion, as well as those areas with higher potentials for invasion should seed sources become available. Though a case study on an Ohio forest, these tools can be modified for use anywhere Ailanthus is invading.

“…The relationship between growth performance at early life stages and invasiveness can be evaluated by the probability of dominance and dispersal which are two important aspects in predicting non-native species invasion in forests 86 . Most data in the present meta-analysis were from experimental comparisons on the growth and stress-tolerance of native and non-native species pairs, reflecting the early establishment of plants.…”

Introduced non-native mangroves express better growth performance than co-occurring native mangroves

Mangroves are salt-tolerant woody species occurring in tropical/subtropical coastal habitats. plantation of fast-growing non-native mangrove species has been used as a tool for mangrove restoration/ reforestation in several countries. However, the fast-growth ability can make recently introduced species invasive as they can possibly replace co-occurring native mangroves through expressing higher growth performance and phenotypic plasticity. Therefore, quantifying growth differences between native versus non-native mangrove species is important for forest ecology and management. in this meta-analysis, we compared the growth performance of non-native and native mangrove species pairs by analysing all available results in the literature (33 studies). We found that non-native mangrove species performed better than co-occurring native mangrove species in their introduced regions (Log response ratio = 0.51 ± 0.05) and they also expressed higher trait plasticity. Therefore, these species can be potentially invasive owing to their greater competitive advantage. However, the growth difference was diminished at higher latitudes where native mangrove species seem to perform as well as non-native mangrove species do. This is the first meta-analysis on the growth response of mangroves and it has consequential management implications. We suggest that planting of non-native mangrove species should be avoided and their spread should be monitored.
