All messages that are posted to bionet.announce or bionet.general are
gatewayed into mailing lists.  It wouldn't be appropriate to send 
checkgroup messages to people who are unlikely to be site administrators
and who might not even have USENET at their sites.

I think this is an interesting a potentially useful forum.  However,
one concern that I have is that much 'used' biology equipment is
owned by a government supplying grant funds and often tightly
regulated by university or research foundation administrations.
How would this problem be addressed in such a forum?

        One objection might be that not everyone receiving Bionet (such as

 gating the sci.bio.used-equipment through a Bionet mailing list.

Subject:      Image processing newsgroup under discussion

There is presently a discussion going on in news.groups regarding the
creation of a USENET newsgroup devoted to image processing.  It was
originally proposed as comp.graphics.image-proc, but a good case is
being made for sci.imaging, which would be a group for scientists to
discuss their image processing problems.  From the volume of discussion,
it looks likely to me that some such group will be created.

Please participate, by posting a short note such as "I would read
sci.imaging" to news.groups, with subject line "Re: RFD for new IMAGE
PROCESSING newsgroup".
Some other proposed names were comp.imag-pro, comp.dsp.imaging, etc.

Also, a mailing list for interested people has been set up, send subscribe
requests to image-proc-request@skyking.oce.orst.edu.  The list will
probably be discontinued once the newsgroup is created.

On USENET news systems the newsgroup names correspond to directory
structures under the main news directory, e.g., there is a bionet
directory on the same level as comp, sci, etc. and then for example
one would find bionet/molbio/genbank using typical UNIX directory
nomenclature.  We try to fit new names within existing directory
structures (hence bionet.biology.used-equipment places one
used-equipment subdirectory under the existing bionet/biology
directory while bionet.equipment.recyle creates two new directories)
when its is not too artificial, but there is no denying that the
bionet structure is influenced by its initial molbio roots.

Whether it is worth while reorganizing the whole thing at this point
is debatable.  I personally have no strong reservations from the end
user perspective but a lot of systems people do not like shifting the
directory structure around and it would also complicate archiving.

In summary, these are not just arbitrary names that we can change at
will.  The names are a direct representative of the UNIX news file
structure as it exists on hundreds (actually thousands) of machines.

Kenton Hoover, our USENET systems programmer, also says (staring over
my shoulder) that these reorganization attempts are usually
short-lived successes.  Regardless of the structure decided upon there
usually happens along people or new circumstances that either disagree
with the chosen structure soon thereafter or come up with situations
that don't fit well within the chosen heirarchy.

I guess in light of this I'd have to ask what would we really gain by
merely shifting the names around?

She was a Polish research worker, who I am told has now gone to Malaysia.

From what I can remember mechanical stress could be viewed in two ways
Thigmomorphogenesis and seismomorphogenisis. ( Wonderful scientific sounding
words) In actual fact the former was defined by Jaffe in 1976 and refers to
the retardation of growth caused by physical contact, and the latter refers
to retardation induced by shaking or the wind Mitchell 1975

The masters thesis that I looked at was done at Helsinki University
If you want the references then perhaps you could fax them at the number
below. Department of Plant Production fax +358 0 708 5582

Young tissue seems to be specifically sensitive to MS (Mechanical Stress)
stimuli, and often brushing or shaking of plants can also be combined with
nutrient hardening to produce sturdy plants that survive transplanting.

For example Cauliflour seedlings fed with low amounts of nitrogen and
potassium are tougher and more compact. They have a dry matter % weight
which is twice that of normal plants, and do not wilt after transplanting.

With Tomatoes, MS causes a reduction in node and leaf number, shortening 
of internodes, nodal swelling, deep greening of new leaves, and increased
lateral branch development (Mitchell 1975) Beans that had been brushed and 
rubbed were greatly hardened against breakage. The elastic strength of the 
stems was related to the cellulose fraction in the stem fibre, and MS treated
plants withstood bending of about 90 degrees whereas untreated controls broke
due to slight bending. (Heuchert 1983)

So the take home pay is that if you want to grow tough plants then get
tough with them.

If the forum was used just for "advertising" then its probably not a  
problem.  The two parties would have to work out terms then arrange
the paperwork.  From discussion with admin. people here things can 
be transfered from one place to another as long as the proper paper 
trail is laid down.  How to deal with $'s may be a bit of a problem 
but that really will have to be worked out locally.

I think that this is a good idea.  A lot of perfectly good   
equipment is stored all over the place and creating a marketplace
for its orderly transfer to people who need it seems a reasonable 
use of bandwidth.  This group may be particularly useful for those
researchers who find themselves at small Colleges or Universities 
and need basic equipment but don't have $'s to buy it new.  I've
seen my Dept. send perfectly good equipment to surplus that I know
somebody could use.  Here sending something to surplus means storing
it outside where is soon can be classifed as junk.


Why not call the group   --  bionet.equipment.recycle  -- ? 
Al 
Once somebody starts using the "system" for this they might be inclined 
to explore other groups.
  

Be well ---

To follow up with Sam's answer to Joachim Benz's query:
Is plasticity necessary for success?

I'm doing one of those theses Sam was talking about with a
vegetatively reproducing plant, cranberry.  I don't know about
Lolium, but in cranberry there seems to be very low intrapopulational
genetic variation, therefore one individual plant may spread
over quite a large area.  It seems that selection may favor
plasticity in such a case in which the spreading growth habit
may exploit putative spatially heterogeneous environments.
Unfortunately, my common garden experiments are just beginning,
so I can't provide data to support this.  Most plant phenotypic
plasticity studies have been done with fast-growing annuals,
so clonal plant plasticity is a black box (especially woody plants).

Hope this helps.

No, phenotypic plasticity is never a requirement.  Theoretical
models agree that 2 conditions are necessary for selection to
favor plasticity, environmental variability and predictability
of that variability.  By predictability I mean that the
environment at the time the phenotype becomes fixed must be
highly correlated with the environment at the time of selection.
The above is for temporal variability.  For spatial variability
it depends on the relative difference in the 2 optimal
phenotypes vs the cost for being plastic.  See the recent
papers by van Tienderen (Evolution 45:1317-1331), Gabriel and
Lynch (J. evol. biol. 5:41-59), and de Jong (J. evol. Biol.
3:447-468), and upcoming papers by Gomulkiewicz and
Kirkpatrick (Evolution in press) and Gavrilets and Scheiner

   So before I can answer your question concerning Lolium it
is necessary to know something about the pattern of environmental
variability, migration patterns, and effects of environment on
phenotype.  However, it is true that plants in general tend to
be plastic, more so than animals.  A reasonable guess why is
because they are not mobile.  At this point we have not
accumulated enough information to predict which which types of
plants or plant traits are more likely to be plastic than
others.  So there is at least 2 or 3 PhD theses of work
waiting to be done.
