Summary
Vector - The manner in which species are introduced into new locations
Pathway - The route the vector takes

Summary
Human-Mediated vs Natural Transport
Intentional vs unintentional Transport
Transport Vectors: Food and Game Environmental Enhancement Biocontrol Conservation and Scientific Pursuits Unintentional
Transport Pathways: Spatial and Temporal Dynamics

Exotic Invasives and Their Transport Vectors
What is surprising about this table?

Discussion Questions
• How specific do we need to be when examining transport of invasive species?
Should all vectors be considered? Just the significant ones?

Discussion Questions
• How does the economical image of invasive species change depending on its
degree of invasiveness? I.e. St. John’s Wort and Dandilions

Discussion Questions
• Are intentional and unintentional transport quantifiable? What variables would you
include in this calculation?

Discussion Questions
• Is there a record of marine fish extinction over last few hundred years? What is the explanation for the lack of exotic marine
fish introductions? Is this a good model for non-human-mediated (natural) invasion?
Why/why not?

Discussion Questions
• Since ornamental species are very desirable amongst the general public, where should the scientific community
draw the line between demand and ecological conservation?

Discussion Questions
• Is all human-mediated transport “unnatural”?
