Class Zoom Recordings
3.16.20 - Q&A with Felicia Keesing - the conclusion of our jigsaw discussion of papers on Lyme Disease and the biodiversity dilution effect. This starts out as a video and becomes more of a podcast as we encountered internet connectivity issues. The questions you guys asked were fabulous and Dr. Keesing's responses were so interesting. We learned a lot, hope you did too!
4.2.20 - Food web Thursday discussion. You all did an amazing job figuring out the structure and dynamics of the Among Ripples pond food web. A few take-home messages: 1) doing field food web work is extremely challenging (you saw how long it took you to compile the highly controlled and simple food web in among ripples), 2) due to both direct and indirect effects, predicting the response of the system to a perturbation can be very difficult (you guys did an amazing job at designing, carrying out and then explaining your experiments), 3) communities, in general, and food webs, in particular, are dynamic entities, and, as such, we can only have a snapshot of its state at any given time, and even that is tough enough. Yet, as they account for the flux of energy and matter across ecosystems, and human populations relay on them for their own food (think fisheries, for example )food webs are a central ecological concept of both fundamental and applied importance.

4.9.20 - Ecosystem Ecology - the Carbon Footprint
Today we shared what you learned from calculating your carbon footprints and putting them into the context of ecosystem carbon stocks and fluxes.
