DON'T DUMP BAIT: Marine Bait Worms as a Potential Vector of Non-Native Species (2009; PDF | 353 KB)
University of Connecticut. Connecticut Sea Grant.
Researchers from the University of Connecticut and SUNY Purchase completed a study that reinforces concerns that live marine bait, such as bait worms, and more particularly, the seaweed or other material they are packed in, can serve as a vector or pathway by which organisms from one region can be introduced into another. The study was funded by the Environmental Protection Agency Long Island Sound Study, with additional support from Connecticut Sea Grant. For the complete study results, see the Long Island Sound Study: EPA Assistance Award Final Report (2009; PDF 183 KB).

Protect Your Ports Against Invasive Species (Sep 1, 2009)
International Union for Conservation of Nature.
A new report Neighborhood Watch: Early Detection and Rapid Response to Biological Invasion Along US Trade Pathways (2009; PDF | 9.4 MB) says accidental introductions of pests and pathogens threaten economic, environmental and public health. The report offers recommendations to improve biosecurity measures at U.S. ports, as well as a possible funding mechanism based upon the "polluter pays" principle. Recommendations include improved coordination between agencies and greater international cooperation. Neighborhood Watch follows an earlier volume "Denying Entry: Opportunities to Build Capacity to Prevent the Introduction of Invasive Species and Improve Biosecurity at U.S. Ports" (2007; PDF | 4.6 MB) which addressed the challenges of "regulatory exclusion" of potentially invasive species through trace pathways.

A survey of zoos in Spain has revealed that many animal enclosures are not secure, increasing the risk that non-native and invasive species will make their way into the wild.

MetroInvasive - Globalization, Metropolitan Areas, Invasive Species
MetroInvasive.
Collaborative project between Federal Agencies and Universities researchers. Provides a perspective that considers urban areas as hubs of human-mediated invasions in natural and managed ecosystems and provides resources to enhance our understanding of the role of international trade in the dissemination of invasive species. Contains maps of hot spots for human-mediated invasions where early detection strategies could be implemented.

Movement of invasive aquatic plants into Minnesota (USA) through horticultural trade (Jul 2004) (USDA access through DigiTop)
ScienceDirect; Biological Conservation.
Academic Study on Horticulture as a Pathway: Jun 2004, a study by Kristine Maki and Susan Galatowitsch in the Journal, Biological Conservation (Volume 118, Jun 2004, pp 389-396) entitled, "Movement of invasive aquatic plants into Minnesota through horticultural trade," reported that horticultural trade is implicated in the introduction of invasive aquatic plants over long-range distances into new regions of the United States. The results of the study found that:

  • 93% of the orders received from aquatic plant vendors contained a plant or animal species not requested in the order
  • 90% percent of the purchases contained plant receipts not ordered
  • 80% included additional animal receipts
  • 63% had algae, moss or fungi associated with the ordered plants, and
  • 43% contained unordered seeds.
