Tim Covino, PhD student of soon-to-be colleague Brian McGlynn, has been awarded an NSF post-doctoral fellowship to work with Emily Bernhardt and I at Duke. Tim's dissertation developed the use of pulsed solute additions to streams to assess nutrient uptake kinetics, and his post-doctoral work will expand the application of these approaches to new systems and new ecological questions. Congratulations Tim and welcome aboard!
The Bernhardt and Heffernan labs were fortunate to have our friend and mentor Nancy Grimm as our guest this past week. Nancy is a world-renowned expert in biogeochemistry, stream and riparian ecology, and urban ecosystems. She is currently on leave from Arizona State Unviersity, where she was a collaborator and unofficial committee member, while she serves as program director for the National Science Foundation's Ecosystem Science Program.
Nancy's first talk addressed her work in desert streams and their past and future response to climate variability. Some of her lab's current work builds on my dissertation research on desert wetlands, which was very exciting to see!
Nancy's second talk focused on funding opportunities at NSF, covering programs as small as supplemental support for high school students to programs as large as the new foundation-wide sustainability initiatives. There are lots of new programs at NSF as well as changes to how proposals and panels are working, so this was really helpful and interesting.
We also got a chance to take Nancy out to the Eno River, which runs through north Durham and eventually in to Falls Lake. The land surrounding the Eno is largely undeveloped, thanks to the Eno River Land Trust, and the Eno River State Park is just beautiful. We spent lots of time talking about floods, vegetation, and nitrogen in rivers; turning over rocks to see mayfly, stonefly and caddisfly larvae; and spooking turtles sunning on boulders and logs. Good times.

I am an Assistant Professor in the Nicholas School of the Environment at Duke University. My research is focused on the causes and consequences of major changes in ecosystem structure, mostly in streams and wetlands.
