Dear Coral-Listers
In Doug Fenner's recent post on the types and origins of Tubastrea
corals in the Caribbean+GoM, his need to explain the different meanings
of 'introduced' versus 'invasive' highlight how the jargon used in
bioinvasion studies, policies and management continues to provide a
confusing picture.
The understanding and management of bioinvasions remains an emerging,
immature science, and its terminology continues to evolve but remain
loose. As Quine noted in 1946 (and picked up by Carlton in 2002): "The
less a science has advanced, the more its terminology tends to rest upon
uncritical assumptions of mutual understanding". In the case of
bioinvasions, the potential for misunderstandings and confusion - and
the need for people to keep re-explaining what they are writing - has
grown over the last 50 years - from Elton to the latest coral list post.
And there's still no convenient, widely-accepted or commonly-referenced
glossary of terms that provides an integrated set of coherent, logical
definitions for aquatic bioinvasions - based on the process of
introduction, establishment, spread and ultimate perceived impacts
(neutral, harmful or serendipitous).
Despite several papers and reviews pointing out this issue, invasion
scientists and managers have yet to adopt and promote such a glossary or
standard. Why? Firstly, there has been growing need for researchers,
managers and policy makers to condense, compress and, above all,
sensationalise their jargon, if it's to have any chance of catching
mass-media attention, public interest, industry support and the nod of
funding approval from a government treasury, international development
agency, NGO, business unit or philanthropic trust.
Another reason concerns maturity. Most of the matured applied sciences
have well-established international chartered associations and guilds to
help standardise, educate and promote the societal value of their
particular field - such as marine engineering, corrosion science,
coating science. Perhaps it's time to establish an 'Institute of
Biosecurity Engineers' or equivalent, where professionals and scientists
in the bioinvasion control business can identify and adopt standards,
educate and promote responsible research, and provide other measures to
limit misinformation, confusion and charlatanism (quackery practise).
In the free publications list on the ISSG website, there is a GISP
published 2005 review ("Best Practice for the Management of Introduced
Marine Pests - A Review") which has a detailed Chapter 2 that addresses
in detail the terminology and jargon issues of marine bioinvasions. The
whole 2.2MB PDF review is downloadable free at

*/Biofouling Management Session/*/at World Ocean Council's *_Sustainable
Ocean Summit_* (22-24 April, Washington DC)./
The multi-industry ocean leadership event that also includes the "Oceans
2050" workshop [where delegates will identify drivers,
trendsand scenarios affecting future ocean business across all sectors,
and map critical pathways for achieving responsible industry success].
The Biofouling session will address the risks and costs of failing
biosecurity clearance, how companies can evaluate the biosecurity risk
posed by
vesselsmoving between jurisdictions, and a new pan-industry platform to
address these issues and minimize business risk.
