Readings for 10/19-10/21

Last week we looked at vectors of non-native species introduction from a historical point of view. This week we take a look at the present, with a focus on the species you chose for your semester projects.

Tues 10/19

• Each of you has been assigned two readings, based on the type of organism you are studying. That means some of the articles will only be read by one person, others will be read by many. You should be prepared to discuss the key points of your paper, and think about these questions: What are the specific pathways discussed? Are they obvious or obscure? Are they vectors for a few species or many? What are the specific vectors for your study species?
  
• At least one of the articles each of you is reading comes from this book:
  Invasive Species - Vectors and Management Strategies, edited by James T. Carlton and Gregory M. Ruiz. Island Press, 2003.
  
• Some of you will also be reading part of this paper, which I posted on Prometheus: "Horticulture as a pathway of invasive plant introductions in the United States." (2001) by Reichard, S.E. and P. White. Bioscience 51: pp. 103-113
  
• Others will be reading portions of this report: "Pathways and Management of Marine Nonindigenous Species in the Shared Waters of British Columbia and Washington" (1997)

Thurs 10/21

• Each of you received a copy of the Final Report of the Invasive Species Pathways Team. The ISPT is an offshoot of the national Invasive Species Advisory Council. Anyone can get a copy of the report here, but the margins in this original version make it difficult to print out.
  
• Each of you also chose a main pathway to research for this day's class. You will need to choose a specific subpathway to focus on - expect an email from me about it.
  
  Collect as much information as you can about this subpathway, and we will fill out our risk assessments together in class. Feel free to use web-based resources, but be sure to consider their validity. This will be a graded homework assignment - I will collect your risk assessments and any related sources or source lists at the end of class.
