The mesquite trees are beginning to leaf out at our NutNet plots.
Check out the thorns on those guys! The pink flags in the background are initial markers for the NutNet plots.
We hope to have something more permanent in soon!

Lizz's light by Nitrogen addition experiment is up and running! She is examining the relative influence of light and N on leaf- and whole plant-level processes.
This (relatively) simple experiment will help us better understand how N influences productivity. We hope to use her results to improve the processes represented in Earth System Models.

The Smith Lab was just approved to set up a Nutrient Network (or "NutNet" ) site in Lubbock!
Along with the core measurements, we will specifically focus on physiological responses to nutrient addition in West Texas Rangeland species. Get in touch if you'd like to collaborate!

Check out our new Eos meeting report on modeling global change ecology.
The report, led by Susan Cheng with help from Nick and Alison Marklein, examines major topics of discussion from our ESA ignite session last August.
We have students in the lab! Mahum Haque, undergraduate (Biological Sciences), will be examining chlorophyll allocation under different light and N environments. Austin Cooper, undergraduate (Biological Sciences), will be examining biomass and nutrient partitioning under different light and N environments.
Jorge Orchoa, undergraduate (Natural Resource Management), will be helping to set up out new NutNet experiment. Josh Gutierrez, undergraduate (Biochemistry), will be helping Lizz mix and apply different fertilization treatments in her greenhouse experiment.

We just published an new study in Annals of Botany - Plants.
The study comes out of the Boston Area Climate Experiment (BACE), a warming by precipitation manipulation experiment in Waltham, MA.
In the study, led by Vikki Rodgers, we examined seedling trait responses (from leaf- to whole-plant scale) to the treatments and found that warming exacerbated plant sensitivity to rainfall.
These results are consistent with other results at BACE that suggest that warming, while beneficial under high rainfall, can induce water loss that can exacerbate the negative impacts of low rainfall on ecosystem functioning.
See PI Jeff Duke's publications for more results from the BACE.

Nick will be at the annual Ecological Society of America Meeting in Portland, OR from August 6-11. He will be presenting his work on modeling Vcmax from first principles on Thursday, Aug. 10 at 8:00 AM. Contact Nick for a copy of the presentation.
