Abstract

•
Invasive species, known for destabilizing ecosystems, may induce biotic homogenization by reducing functional diversity compared to non-invasive species. Root traits, such as exudate production, play a significant role in belowground plant interactions. However, the differences in these traits between invasive and non-invasive alien species, as well as their potential to contribute to functional homogenization, remain insufficiently understood.

•
We investigated whether invasive species (1) exhibit distinct root morphology and exudate metabolome and show greater homogeneity than non-invasive species, and (2) how functional dissimilarity changes with increasing phylogenetic dissimilarity in invasive versus non-invasive species by analyzing root morphological traits and exudate metabolome profiles in 65 plant species with different invasion status.

•
Results showed no significant differences in root morphology or exudate metabolome composition, though certain metabolites differed between the two groups. Overall, invasive species were more homogenous in both aspects, even after controlling for their phylogenetic relationships. Non-invasive species exhibited increased functional dissimilarity with increasing phylogenetic dissimilarity in root morphology, while the opposite was observed in root exudate metabolome.

•
Our study indicates that invasive species exhibit greater functional homogeneity, leading to reduced functional diversity. This reduction leads to lower ecosystem multifunctionality and niche complementarity, potentially posing a significant threat to ecosystem functioning and soil biodiversity.

期刊介绍： Environmental and Experimental Botany (EEB) publishes research papers on the physical, chemical, biological, molecular mechanisms and processes involved in the responses of plants to their environment. In addition to research papers, the journal includes review articles. Submission is in agreement with the Editors-in-Chief. The Journal also publishes special issues which are built by invited guest editors and are related to the main themes of EEB. The areas covered by the Journal include: (1) Responses of plants to heavy metals and pollutants (2) Plant/water interactions (salinity, drought, flooding) (3) Responses of plants to radiations ranging from UV-B to infrared (4) Plant/atmosphere relations (ozone, CO2 , temperature) (5) Global change impacts on plant ecophysiology (6) Biotic interactions involving environmental factors.
