Stream Ecology on the Block – Part II

This past week in EV311 (Stream Ecology) we added biology to the mix and visited Beaver Creek State Wildlife Area near Penrose, Colorado to examine how small scale habitat changes in streams can affect who lives there (i.e. macroinvertebrates). We also collected water for alkalinity and dissolved oxygen measurements – because every good …

Special Issue on N Footprint

Nitrogen footprints for institutions present a broad picture of campus sustainability because reactive nitrogen contributes to both local and global impacts on ecosystem and human health, from urban smog and eutrophication to global climate change. The Nitrogen Footprint Tool (NFT) estimates the total emissions of reactive nitrogen resulting from institution …

Adventures in Biogeochemistry

This year in EV 211 | Human Impacts on Biogeochemical Cycles, we are examining the topic through the lense of agriculture. Focusing on how different agricultural practices, especially those practiced in the Western United States, alter the way the soil is storing carbon and nitrogen. We took two field trips …

N Footprint Workshop

Colleen Orr (CC ’17) and I attended the N Footprint Workshop in Durham, New Hampshire in June.  Colleen presented Colorado College’s preliminary N Footprint. Representatives from 18 of the schools involved in the program – ranging from Boston University and Colorado State to Dickinson College and the Marine Biological Lab. …

Team Fire

Team Fire has spent the last five weeks collecting soil and water samples from burned and unburned Ponderosa watersheds. At the start of June we were joined by Brian Buma (thank you NOVUS Scientist Exchange Grant) who taught us how to quantify fuel loads, above ground biomass, etc. You can …
