Predicting future invaders and future invasions.

Area of Science:

• Ecology
• Conservation Biology
• Invasive Species Research

Background:

• Invasive alien species pose significant global threats to biodiversity and human well-being.
• Preventing introductions is the most effective strategy to mitigate impacts and costs associated with invasive species.
• Proactive identification of potential invaders and invasion risks is crucial for effective management.

Purpose of the Study:

• To develop and illustrate a profiling method for predicting which species are likely to become invasive.
• To identify specific ecological traits associated with invasive species.
• To pinpoint geographical regions at high risk of invasion by newly identified potential invasive species.

Main Methods:

• Statistical profiling of 1,002 ant species using an extensive trait database.
• Identification of species with ecological profiles matching known invasive ants.
• Integration of species distribution models with predictive profiling to map invasion risk hotspots.

Main Results:

• Thirteen native ant species were identified as having ecological profiles indicative of future invasive potential.
• These 13 species are predicted to become the next wave of global invaders.
• High-risk invasion regions include Florida, Central America, Brazil, Central Africa, Madagascar, Southeast Asia, Papua New Guinea, Northeast Australia, and numerous islands.

Conclusions:

• The developed profiling framework offers a powerful tool for predicting future biological invasions.
• This approach enables the implementation of timely, targeted, and proactive management strategies.
• The methodology is adaptable to other taxa, offering broad applications in invasive species management and conservation efforts.
