My name is Phil Starks. I am a graduate student at Cornell University in the field of NeuroBiology and Behavior. I am currently examining paper wasps, specifically Polistes dominulus. I am evaluating their nesting behavior and population genetics. I want to compare animals from different regions -- mostly from the Northeast in areas between Boston, MA and Ithaca, NY. My problem is finding these critters. They tend to congregate in the eves of man-made structures. I have searched state parks and some universities but have only found 4 usable sites. A usable site is one that has been relatively undisturbed (not sprayed with insecticides) for a few years and contains 18 or more colonies. These wasps make un-enveloped nests -- you can plainly see the cells of the comb (it looks much like a gray honeycomb). P. dominulus is the more yellow and smaller of the 2 Polistes species in this region (P. fuscatus is dark brown and the larger of the two animals). At this time of year you may see colonies with anywhere from 1 to 10 individuals, and nests that may contain 8 to 100 cells. If you know of any potential sites please email me. I am offering a $20.00 finder fee for useful sites.

Unfortunately, there is no general way to predict base composition, codon usage, gene organization for ciliates as a group (or for "higher" or "lower" organisms, whatever those groups may signify). For a start, I would assume roughly equal frequencies for all for nucleotides, and few introns. If you know anything about ANY gene in Fabrea salina that would give you some idea of how far off these assumptions are. Also, use ITP nucleotides for degenerate positions, and try to PCR short fragments (~200 nt) to minimize the possibility of introns.

That said, look to other protists in this order: 1) other ciliates 2) dinoflagellates 3) apicomplexans 4) oomycytes 5) chrysophytes These are all part of a "late eukaryotic radiation".

COMPUTER-AIDED IDENTIFICATION OF DIATOMS FOR USE IN WATER QUALITY MONITORING Diatoms (microscopic unicellular algae) are excellent indicators of river water quality, but the difficulty of identification presents a major obstacle to their use in routine monitoring programmes. The aim of this project is to apply expert identification systems and image analysis techniques to develop a computer-aided approach to diatom identification. Material from a current project in the Department of Geography on diatoms and river-water quality in NE England will be used to explore methods of rapid image capture to develop a reference library of light microscope images of c. 100 taxa, some closely related and morphologically very similar, others more diverse. This library will then be used to develop methods of image description and comparison, using easily obtained (though mathematically complex) morphological and textural attributes. The successful applicant will be based in the Department of Geography under the supervision of Dr. S. Juggins but will also spend time working in the Department of Electrical and Electronic Engineering and at the Royal Botanic Garden, Edinburgh, under the supervision of Prof. O. Hinton and Dr. D.G. Mann respectively. The applicant will be trained in taxonomic methods, diatom systematics, and statistical/numerical techniques, and will gain experience in advanced light microscopy, image analysis, and databases. We are looking for highly motivated applicants with a good honours degree, normally at least an upper second, with a biological and/or mathematical/statistical background. Previous experience in one or more of the following areas would be an advantage: diatom analysis, image analysis, pattern recognition, neural networks, multivariate statistics, computer programming.

For those of you who don’t know, these are infections that can be transmitted between humans and other animals. Whether you are a DVM, MD, wildlife rehabilitation personnel, biologist, epidemiologist, just an interested individual or whatever, I’d like to correspond with you. A multinational conversation would be nice. I’ve been interested in zoonotics for many years and find only passive interest in the scientific community. As for money for research opportunities, ......... need I elaborate? Topics that have struck my fancy are new and emerging infections, land management and the emergence of new foci for zoonotics, the search for animal reservoirs other than cattle of E. Coli O157:H7, animal reservoirs in general, mechanisms involved in host or target organ specificity, new cross species infections and their consequences (Ebola), methods of surveillance and preventive measures against transcontinental spread of disease and animal reservoirs, and many more. I’m interested mostly in creative individuals. Many subjects are not being addressed by the scientific community nor by the population in general. I would like to meet those people that want to be creative in addressing these issues in the areas of public awareness and in concrete actions. I hope to put up a colorful and inventive homepage on the World Wide Web (in English and other languages with your help) for zoonotics. Anyone having experience that could help me in this endeavor would be more than welcome. PLEASE ADDRESS ALL RESPONSES TO MY E-MAIL ADDRESS : rwhitha@eagle.cc.emory.edu. Any suggestions would be appreciated. You can correspond with me in English ou en Français si ça vous chante. Raymond G. Whitham, MD, DVM
