Congratulations to Rhenton, one of the 2018 Chancellor’s Summer Scholars! He is studying nutrient limitation of algal and microbial biofilms in the Yakima Watershed.
Phil Robertson, Dan Buckley, and I have received NSF funding to work on associative nitrogen fixation in perennial grasses! We will be using isotopic tracers to determine when nitrogen fixation occurs, estimate N inputs on an annual scale, identify the microbes fixing N, and examine the plant-microbe relationships underlying this process. Looking forward to this exciting, challenging project!
In our latest paper, we found some really interesting seasonal patterns in associative nitrogen fixation. Check it out!
Our paper on invasive plant effects on denitrification is out in Freshwater Biology! We use the push-pull isotope pairing technique to examine the effects of Phragmites australis on nitrogen removal. Check it out: doi.org/10.1111/fwb.13073
