Canadian Government support traditional taxonomy

[christian thompson]

Robin:

It is not only that, but the Canadian Government seems to have bought
into Paul Hebert's DNA barcode taxonomy. Just sequence the first couple
of coding regions of the CO1 gene, use the first 15 position for a
barcode, and now you can do what traditional taxonomists have failed to
do in the past 250 years, rapidly inventory the World Biota!

So, Robin, your government is way ahead of the rest of the World!

Jeff and Others,

The money for "traditionalists" to do intensive, original morphological
and
taxonomic research is simply not there.  THAT is the reason for
nothing
being done in this field.  It is not for lack of interest.  Faculty
can
support neither their own research, nor that of students, in this area.
 In
fact, each time someone does more original morphology work, it is a
real
contribution for everyone, including the moleculars and taxonomists.

What is needed is money, and then cooperation between the moleculars
and the
morphologists and, yes, even taxonomists.  Relatively speaking, the
moleculars are on a roller coaster ride financially, and the rest of us
are
back at the loading dock, able to do no more than watch the riders.

Governments are frugal and stingy, especially the Government of Canada,
and
unless a government sees where it can make political hay for future
votes,
the funding is not there.  Here in Canada, for example, the federal
gov't
just committed $100 million for SARS research. (Note that the money did
not
come in the heat of SARS, but after!)  This is a high-profile area,
lots of
publicity and politics.  This from a government that could not find
money to
do many other things of lower social and health profiles for the past
few
years, and which has been cutting back even on firearms safety courses.
 Now
the benevolence of our federal govt can be seen in high profile.

I am waiting to see if similar amounts of money will be calved off for
research on the Nile Virus - again a high profile, political topic,
and
which may become a big problem in Ontario and westward.

Perhaps what academics should do is go to large industries (Shell,
Esso,
etc.), prick their societal consciences, and try to set up say $50,000
to
$100,000 research funds for non-directed research.
