We welcome Laura Yahdjian to the Sala Lab. Laura is a visiting professor from the University of Buenos Aires who works in grassland ecosystems. She has carried out important work on water controls on decomposition and nitrogen cycling in arid ecosystems. She is currently interested on the effects of land use on greenhouse-gas emissions. During her stay at ASU, Laura is working on issues of grassland ecosystem services and how they are affected by woody-plant encroachment. Stop by and say hi to Laura!
