Manage biological invasions like natural disasters, biologists say

01.04.2011
Large-scale, persistent impacts and limited predictability of some alien invasions demand a coordinated response strategy

Biological invasions get less prime-time coverage than natural disasters, but may be more economically damaging and warrant corresponding investments in preparedness and response planning, according to three biologists writing in the April issue of BioScience.

Anthony Ricciardi of McGill University and his coauthors point out that species invasions are becoming more frequent worldwide, largely because of international trade. Although many alien species establish themselves in a new location without causing harm, the worst biological invasions may cause multiple extinctions of native species, as when the Nile perch invaded Lake Victoria and contributed to the extinction of 200 fish species. Biological invasions can also be hugely expensive: the destruction of ash trees by the emerald ash borer is projected to cost the United States $10 billion over the coming decade.

Like natural disasters, biological invasions are hard to predict and extremely difficult to control once they get under way. And like catastrophic events in high-tech industries, invasions are usually inevitable and can cause problems through unexpected interactions, as when floating mats of algae caused by invasions of freshwater mussels led to several emergency shutdowns of a nuclear reactor in New York State in 2007. Yet despite being slower in their onset, invasions have more persistent impacts and a greater scope of ecological and economic damage.

Hazard-reduction plans could minimize the impacts of biological invasions, the researchers argue, and at a cost that is low relative to the cost of a major event. Vulnerability reduction practices, rapid response and assessment, and systems for sharing of information and coordination among authorities are all potentially beneficial. New Zealand has passed legislation to coordinate management of threats to its biodiversity and natural resources under a central authority, but other countries have yet to follow its lead.

After noon EST on 1 April and for the remainder of the month, the full text of the article will be available for free download through the copy of this Press Release available at www.aibs.org/bioscience-press-releases/.

BioScience, published monthly, is the journal of the American Institute of Biological Sciences (AIBS). BioScience publishes commentary and peer-reviewed articles covering a wide range of biological fields, with a focus on "Organisms from Molecules to the Environment." The journal has been published since 1964. AIBS is an umbrella organization for professional scientific societies and organizations that are involved with biology. It represents some 200 member societies and organizations with a combined membership of about 250,000.

The complete list of peer-reviewed articles in the April 2011 issue of BioScience is as follows:

Freshwater Commercial Bycatch: an Understated Conservation Problem with the Opportunity to Learn from the Marine Realm.

Graham D. Raby, Alison H. Colotelo, Gabriel Blouin-Demers, and Steven J. Cooke.

Im Focus: Light-induced superconductivity under high pressure

A team of scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg investigated optically-induced superconductivity in the alkali-doped fulleride K3C60under high external pressures. This study allowed, on one hand, to uniquely assess the nature of the transient state as a superconducting phase. In addition, it unveiled the possibility to induce superconductivity in K3C60 at temperatures far above the -170 degrees Celsius hypothesized previously, and rather all the way to room temperature. The paper by Cantaluppi et al has been published in Nature Physics.

Unlike ordinary metals, superconductors have the unique capability of transporting electrical currents without any loss. Nowadays, their technological...
