These students will start the program in Fall, 1995 and be funded for five years. The stipend is $14,000/year, with full tuition paid, plus a stipend for travel and supplies. The Evolutionary Ecology cluster also has a $1.5 million grant to support research which can be used to assist graduate students. Students who receive a GRT must be US citizens or residents. Students who receive one of the Training Grants must conduct a research project in either ecological/evolutionary parasitology or use molecular techniques in some area of ecology-evolution-or animal behavior. The Graduate Program especially is interested in applications from women or members of minority groups not well represented in science. A full packet of information (including application materials) can be obtained from Jos. J. Schall, Department of Zoology, University of Vermont, Burlington, VT 05405 or by e-mail at jschall@moose.uvm.edu From owner-protista@net.bio.net Tue Oct 04 23:00:00 1994 Path: biosci!agate!howland.reston.ans.net!EU.net!sunic!trane.uninett.no!astfgl.edb.tih.no!pc013.kjemi.tih.no!bjorn From: bjorn@kjemi.tih.no (Bjorn Ness) Newsgroups: bionet.general,bionet.mycology,bionet.protista Subject: Xylitol - production from xylan (hemicellulose) - fermentation Date: Wed, 5 Oct 1994 11:18:58 Organization: Kjemiavdelingen Lines: 22 Message-ID: NNTP-Posting-Host: pc013.kjemi.tih.no Keywords: xylitol- production, xylose, xylan, hemicellulose, enzymes, fermentation X-Newsreader: Trumpet for Windows [Version 1.0 Rev A] Xref: biosci bionet.general:11412 bionet.mycology:975 bionet.protista:180 Information needed - please help !

I am looking for a good source of information on a Protist, Trichamonas galinae (sp), the source of a crop infection in columbaforms (pigeons,etc). I work in a wildlife rehabilitation center, and have been asked to describe this protist. The best I can do is to tell the volunteers I work with to look for a flagellated, 'pear-shaped' organism that seems to move against Brownian- motion. I appreciate any help you can give me, even if it is to point me to a better Usenet group to post this question on.

In any case, your description isn't bad but you shoula add that the flagella will be at the fat end of the pear (though teardrop is a bit better) and they appear as a tuft (as opposed to distributed all over) arcing over one side. (They won't see the undulating membrane in fresh preps if they're not trained to do so, so I won't go into detail about that). Also, they should be about the size of a bird red blood cell <- important cuz there might be a bunch of flagellated things in the crop. My suspiscion is that if the birds are suffering some disease symptoms and T.g. is the cause, there will be an overwhelming infection so it should be straightforward). Mark -- Mark E.
