Native Plant Litter Legacy Effects on Invader Competitiveness

Chaofang Sun published a dataset on figshare in June 2026, investigating legacy effects of senescent plant material on invasion success. The data, 111.8 KB in size, includes results from experiments using soils conditioned with healthy and diseased litter from 14 native species to examine impacts on invader Solidago canadensis and native competitor Artemisia scoparia. The study reveals coupled nutrient and disease pathways through which litter deposition promotes invasion.

Use Cases

• Modeling invader-native competition outcomes based on litter nutrient enrichment and pathogen spillover effects.
• Analyzing the relationship between phylogenetic distance of litter donors and the strength of post-senescence legacies.
• Testing predictions of biotic resistance theory by incorporating temporal dimensions from litter deposition.

Strengths

• Includes experimental data from 14 native plant species, allowing for comparative analysis.
• Examines two distinct ecological pathways (nutrient enrichment and pathogen spillover) within a single study.
• File formats include R and XLSX, which may facilitate reproducibility and analysis.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small at 111.8 KB, indicating a limited experimental scope.
