\"SMERplots600\"<\/a><\/p>\n

We are in the 4th year of an NSF-funded rainfall manipulation experiment at Santa Margarita Ecological Reserve, part of SDSU’s Field Station Program<\/a>. The experiment is investigation the interactive effects of plant functional type (native shrubs vs. exotic annual species) and altered rainfall. This is a collaboration with Dr. Elsa Cleland<\/a> at UCSD. Our lab is focusing on belowground responses. Exotic annuals, such as the invasive grass, Bromus madritensis<\/em>, and invasive forbs like Centaurea melitensis<\/em> and Brassica nigra<\/em>, are increasing the vulnerability of soil N and C pools to loss during large rain events.<\/p>\n

We’ve recruited numerous undergraduate students from classes such as Microbial Ecology, Plant Ecophysiology, and Plant Ecology for independent research projects related to this experiment.<\/p>\n","protected":false},"excerpt":{"rendered":"
