Position 1 Undergraduate Research Assistant: part time, less than 15 hours per week, to assist with algaegrazer interactions in Closed Ecological Systems. The work involves moderately heavy computer use (PC) with Word, Excel, Powerpoint, EndNote,SPSS, and a CO2Sys model and to work with an electronic instrument. In addition to understanding the biology, the assistant must be willing to handle chemistry including molar quantities, the bicarbonate cycle (including alkalinity titrations and their interpretations) and gas laws involving O2 and CO2 gas-liquid interactions. While it isn’t expected that the assistant will know these programs and concepts at the beginning, he/she must be willing to become comfortable with them. The research involves designing and setting up experiments, data gathering, data interpretation including statistics, and eventual publication. The laboratory work includes dishwashing, sterilization procedures, media making, algal and Daphnia cultures, and algal and Daphnia counting techniques. Some strength is required to lift about 30 lb and to work with electronic equipment (opening, sealing, lifting). The position is on campus, in 1140 NE Boat Street (Fisheries Teaching and Research Building), and time can be flexible to adjust to class schedules. The position can start this summer to overlap with the present assistant who is leaving for graduate school. Ideally, the student would be in summer school (or at least near campus) and available as an undergraduate for at least one more year. Hourly pay will depend on initial qualifications. Please contact Prof. Emeritus Frieda B. Taub via e-mail (taub@u.washington.edu) providing your interest in aquatic ecology (limnology, oceanography, microbiology), experience culturing organisms, your unofficial transcript, 3 references with e-mail and phone numbers, and your availability summer 2012 and academic year 2012-13, and thereafter. Position 2 Undergraduate Research Assistant: part time (5-8 hours per week), to assist with cultures of algae and Daphnia. The work involves dishwashing/sterilization techniques, media making, algal enumeration (counting, absorbance, and in vivo fluorescence), Daphnia subculturing, Daphnia health assessments. Computer and imaging techniques are a plus. Hourly pay will depend on initial qualifications. Please contact Prof. Emeritus Frieda B.
