photo. The shipping industry is an important unintentional pathway for novel species introductions, and is responsible for some of the highest impact invasions in history (e.g., rats, zebra mussels, mosquitoes). This project seeks to identify properties of ports that lead to invasive species outbreaks, and to study the role of secondary invasions in worldwide species movement. Students will create, analyze and evaluate a network-based mathematical model indicating how shipping networks move both terrestrial and marine species across the globe. This work has the potential to inform management and policy decisions on cargo inspections and risk assessments, and will provide a better understanding of invasive species movement through unintentional pathways.

Product: Comflo - an interactive commodity flow visualization system developed by project participants.

Feature article: Students create tool to stop pests in their tracks
