What does this research mean for the field?

Invasive angiosperms exhibit structured global bioregionalisation patterns (Holarctic, Holotropical, and Austral) that are primarily controlled by regional environmental constraints and species traits, rather than spatial homogenization from anthropogenic activities. Novelty: ClaimNovelty.NOVEL_FINDING. Consensus alignment: ConsensusAlignment.ESTABLISHES_NEW_DIRECTION.

What question did this study set out to answer?

To delineate global bioregions of invasive angiosperms and evaluate how these zones diverge in functional species traits and documented human uses.

Implication

Global biogeographical analysis reveals three distinct latitudinal bioregions among invasive angiosperms, suggesting regional environmental filtering shapes biological invasion patterns.

Key Points

To delineate global bioregions of invasive angiosperms and evaluate how these zones diverge in functional species traits and documented human uses.
Compiled geographic occurrence records for 3,016 invasive angiosperm species across 48 orders and 184 families from the Global Register of Introduced and Invasive Species.
Conducted network clustering bioregionalisation using Infomap Bioregions across total occurrences, non-native records, and invasive species datasets.
Evaluated trait composition across identified bioregions using life form, pollination mode, dispersal mode, propagation type, photosynthetic pathway, and human uses.
Identified three consistent latitudinal bioregions across non-native occurrences, designated as Holarctic, Holotropical, and Austral.
Identified C3 photosynthesis, insect pollination, seed propagation, and medicinal applications as the dominant shared features across all bioregions.
Observed regional divergence in trait representation, with strong trait over-representation in the Holarctic, over-representation of human uses in the Holotropical, and trait under-representation in the Austral bioregion.
