Brian Kielstra


I am a Ph.D. candidate interested in how landscape patterns and processes impact aquatic ecosystems. Currently, I’m using multiscale analyses to explore the cumulative effects of headwater impairment on downstream ecosystems. I’m using headwater streams in the Greater Toronto Area as my study system.

We collaborated with an NGO in the Greater Toronto Area, EcoSpark, to have citizen scientists (a.k.a. The Rot Squad) help assess decomposition rates in headwater streams. Here is some more information:
