UCSB Study Shows Forest Insects and Diseases Arrive in U.S. Via Imported Plants (Apr 9, 2012)
The trade in live plants from around the world has become a major industry in the U.S., with new imports now valued at more than $500 billion annually. According to a study conducted by researchers at UC Santa Barbara's National Center for Ecological Analysis and Synthesis, however, what has proved to be a boon for the economy has also been shown to have devastating effects on the environment. The multidisciplinary working group found that almost 70 percent of the most damaging non-native forest insects and diseases currently afflicting U.S. forests arrived via imported live plants.

UF-led Study: Invasive Amphibians, Reptiles in Florida Outnumber World (Sep 15, 2011)
Florida has the world's worst invasive amphibian and reptile problem, and a new 20-year study led by a University of Florida researcher verifies the pet trade as the No. 1 cause of the species' introductions. From 1863 through 2010, 137 non-native amphibian and reptile species were introduced to Florida, with about 25 percent of those traced to one animal importer.

Forests Under Threat from Exotic Earthworm Invasion: Study Shows Humans to Blame for Spread of Non-Native Species (Sep 1, 2011)
It is widely acknowledged that human beings are largely responsible for the widespread alteration of ecosystems on the planet. A recent study traces the ways in which humans are the principal agents of dispersal of exotic earthworms in the forests of Northern America. Recent findings suggest that humans spread earthworms both inadvertently via horticulture and land disturbance, in the tires and underbodies of vehicles, but also knowingly through composting and careless disposal of fish bait.

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.

On
the Loose: Non-Native Species Could Escape from Spanish Zoos (Apr 16, 2010)
Conservation Magazine. Journal Watch Online.
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.

Protect
Your Ports Against Invasive Species (Sep 1, 2009) /
Neighborhood Watch: U.S. Biosecurity comes into question
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.
