11:30 Positive effects of UV – Several experiments have suggested that UV may have positive
effects on phytoplankton and zooplankton in the Beartooths and in the Pocono lakes. What is
going on? Are these results “real”? Are they direct or indirect effects? How can we follow up on
these interesting results? Bring your graphs to present if you have observed positive UV effects.

8 pm: Group slide show of UV-Lakes activities over the first year. Bring some Power Point
photos to share!

Sunday, October 21
7:00
Breakfast
8:00 – 12:00 – Exact timing and topics to be finalized Saturday evening as needed, but include:
The UV-temperature paradigm – What evidence have we found for the enzyme
kinetics hypothesis and differences in UV responses in high and low UV:T conditions? What is
the value of continuing to use this high vs. low UV:T perspective to guide our research? Are
there other more useful approaches?
Year 2 mesocosm experiments (Don) What will be manipulated? Sampled? Timing?
Miscellaneous –
- Future meeting schedules - David will host spring meeting in Texas on UV damage.
Shall we plan ahead for other future meetings?
- Budget – Costs of mesocosms in years 1 and 2? Other items?
- Annual report to the NSF –
- Web page input/changes
- One pagers – update now or wait until spring? (data not all in yet)
Norm Yan - Feedback, recommendations, and discussion led by external evaluator
Other topics as need arises (suggestions welcome now or at meeting).
12:00 Lunch
Depart at your leisure.
