This month, the Society for Freshwater Science "Making Waves" podcast is releasing a four-part series on teaching in the freshwater sciences. In Episode 35, Cayelan Carey and I talk with Erin Larson about Macrosystems EDDIE, and using modules in undergraduate classes to learn modeling, "big data" skills, and macrosystems ecology. Check it out!
Last Friday, we did our first full-class run of the newest Macrosystems EDDIE module, Teleconnections, here at Virginia Tech! Students combined long-term data from GLEON and NEON lakes across the US with R software and whole-ecosystem models to explore how local to global factors can affect lake temperatures. Take-home message: lake responses to El Niño teleconnections depend on regional characteristics.

I spent the past week at the Ecological Dissertations in the Aquatic Sciences (Eco-DAS) symposium in Honolulu, developing new ideas and collaborations with other early career researchers in the freshwater and marine sciences. Feeling reenergized about exciting paths forward, and thankful for such a kind, thoughtful, and enthusiastic group of people to work with!
Being part of the GLEON Fellowship Program was a highlight of my PhD, so I am thrilled that the paper from our "Source or Sink" working group is out today in Ecological Modelling.
In a nutshell: We developed a simple, dynamic mass balance model to recreate long-term trends in lake organic carbon to understand the biogeochemical, trophic, and landscape processes that determine the fate of OC. Based on our 5 test lakes, the balance of allochthonous to autochthonous carbon is key in determining whether lakes will bury or respire carbon.

My latest paper, and the first paper of the Macrosystems EDDIE project, is out today in Ecology & Evolution ("Power, pitfalls, and potential for integrating computational literacy into undergraduate ecology courses"). Cayelan Carey and I used our experience developing and testing the first two Macrosystems EDDIE modules in classrooms across the country to show the promise of modular lessons to build undergraduate ecology students' confidence using computational tools that are quickly becoming an essential part of ecology research in the era of "big data"
This paper would not have been possible without our awesome team of volunteer faculty testers-- thank you to those who tested our modules and provided feedback!

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!
