I spent most of June on the road with the University of Georgia Interdisciplinary Field Program, teaching ecology as we camped our way across the continent (my segment stretched from Sapelo Island, GA to Mammoth Lakes, CA). One of my favorite things about this program is the connections built in among students' geology, ecology, and anthropology curricula as we visit national parks and monuments, museums, and other stops along the way.
Here are a few action shots from a really great adventure!
Two collaborative projects I'm involved in have new papers out this spring!
From the Coupled Natural Human Systems project (CNH-Lakes), "From concept to practice to policy: modeling coupled natural and human systems in lake catchments" is out in Ecosphere.
And from the SCALER team, a cross-site synthesis of stream metabolism suggestions stream primary productivity may decrease in a warming world. "Continental-scale decrease in net primary productivity in streams due to climate warming" is out in Nature Geoscience.
One of my dissertation papers is now available online through Ecosystems! As part of the SCALER project (see my PhD research page for details), we quantified the carbon, nitrogen, and phosphorus content of benthic organic matter across stream networks from four biomes. While course benthic organic matter fractions were more variable in their carbon and nutrient content, fine fractions were more tightly constrained.
We also compared C:N and C:P ratios to estimated nutritional needs of macroinvertebrate consumers, and found that consumers of course benthic organic matter may be more likely to experience nitrogen or phosphorus limitation, while consumers of fine benthic organic matter may experience carbon limitation.

I'm excited to see our GLEON working group paper out online today! This team came together at the GLEON 17 meeting in South Korea, and has been working since to make this paper a reality. Thanks Fabian for leading the charge!

It's an exciting week in the Carey Lab; undergraduate researcher Arianna Krinos is featured in a VT news article and video for her receipt of an Astronaut Scholarship. I am lucky to work with and help mentor such an amazing individual- go Arianna!
I'm excited that the 1st Macrosystems EDDIE module is now being tested in classrooms around the country! This past Saturday, I led students from the Virginia Tech Freshwater Ecology course as they simulated how different climate scenarios would affect lake thermal structure. We had lots of creative scenarios (and some scary ones!) and I'm excited to see what students in other courses come up with.
