  • Light attenuation characteristics of glacially-fed lakes 
    Rose, Kevin C.; Hamilton, David P.; Williamson, Craig E.; McBride, Chris G.; Fischer, Janet M.; Olson, Mark H.; Saros, Jasmine E.; Allan, Mathew G.; Cabrol, Nathalie A. (2014)
    Transparency is a fundamental characteristic of aquatic ecosystems and is highly responsive to changes in climate and land use. The transparency of glacially-fed lakes may be a particularly sensitive sentinel characteristic ...
  • The role of ultraviolet radiation and fish in regulating the vertical distribution of <I>Daphnia</I> 
    Rose, Kevin C.; Williamson, Craig E.; Fischer, Janet M.; Connelly, Sandra J.; Olson, Mark; Tucker, Andrew J.; Noe, Douglas A. (2012)
    Previous studies have demonstrated independent effects of both solar ultraviolet radiation (UV; 280-400 nm) and planktivorous fish on the vertical distribution of Daphnia. We examined the behavioral response of adult and ...
  • Shifts in microbial food web structure and productivity after additions of naturally occurring dissolved organic matter: Results from large-scale lacustrine mesocosms 
    Sanders, Robert W.; Cooke, Sandra L.; Fischer, Janet M.; Fey, Samuel B.; Heinze, Adam W.; Jeffrey, Wade H.; Macaluso, Amy L.; Moeller, Robert E.; Morris, Donald P.; Neale, Patrick J.; Olson, Mark H.; Dean Pakulski, J.; Porter, Jason A.; Schoener, Donald M.; Williamson, Craig E. (2015)
    Predicting the effects of dissolved organic matter (DOM) on pelagic food webs can be difficult because DOM modifies water column optics and can have contrasting effects on species across trophic levels. We combined large ...
