1. Invasion Ecology: Transport Vectors and Pathways Amy Hopkins and Nicole Cardona

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

3. 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

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

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

6. 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

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

8. 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?

9. 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?

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