Abstract
Making predictions about when and where a given mechanism of invasion will be weak or strong is crucial for the effective management of non-native species. Despite the importance of disturbance on invasion, our understanding of how variation in abiotic and/or biotic conditions may modify the disturbance-invasion relationship is scarce. Here, we aimed to evaluate how abiotic (soil type) and biotic (tree and shrub cover) contexts affect the disturbance-invasion relationship in disturbed and nearby non-disturbed communities in the semi-arid open forest of central Argentina (ca. 36° S) using field sampling. We found that abiotic context modulated non-native species success in disturbed communities, whereas both abiotic and biotic context modulated success in nearby non-disturbed communities. These findings suggest that the plant invasion-disturbance relationship is context-dependent. Our results hint at the possibility that the significance of disturbance in predicting invasion might diminish as the importance of abiotic filters increases.

Chiuffo&Hierro_Oikos2023_Dataset. Dataset containing the data supporting the paper 'Abiotic and biotic contexts shape the effect of disturbance on non-native plant invasion' (Chiuffo and Hierro, Oikos 2023).
This dataset was collected in disturbed and nearby non-disturbed communities growing in sandy and sandy loam soils in the Parque Luro Provincial Reserve (36º 57’ S, 64º 17’ W), La Pampa province, Argentina.
Dataset includes:
- Environment (that is, closed woodland, open woodland, or grassland).
- Site (i.e. number of replicates per environmental context).
- Distance (-5: distance from disturbance border, survey conducted on disturbed communities, 0-300m: distances from disturbance).
- Community (i.e. disturbed or non-disturbed).
- Plot (plot number, 1-5 per distance).
- Non-native cover (percentage).
- Total cover (i.e. native and non-native species cover percentage).
- Non-native richness (i.e. number of non-native species).
- Native richness (i.e. number of native species).
- Photosynthetic active radiation (PAR, percentage of full light).
- Soil type (i.e. sandy or sandy loam).
- x: latitude (decimal degrees).
- y: longitude (decimal degrees).
