Christopher Vito While there exists a large body of research addressing the impacts of changes in precipitation on aboveground net primary production (ANPP), considerably less work has been done to examine belowground net primary production (BNPP). Similarly, there exists a gap in knowledge pertaining to the effect of changes in precipitation over time on BNPP, such as response lags and legacy
Tyler Turk Shrub encroachment into arid grasslands is a widespread phenomenon in drylands globally and the Chihuahuan desert specifically. Encroachment leads to structural and functional changes in the system which facilitate positive feedback loops that further reinforce the shrubland state. Large bare interspaces serve as areas in which wind and water erosion can act, redistributing
Seth Burruss Biocrust are a diverse community of organisms comprising (cyanobacteria, algae, bacteria, and fungi) and macroscopic (lichens, mosses, and microarthropods). They exist in top few centimeters of the soils surface predominantly in drylands and their community structures can vary greatly in heterogeneity. Biocrust are estimated to cover 40-100% of the ground surface in drylands

William Beamon, Gesuri Ramirez, Libia Gonzalez-Alonso, Robin Luna, Alina Jaimes, Craig Tweedie, Marguerite Mauritz In desert ecosystems the appearance of greenness in plants signifies the presence of adequate temporal and spatial resources along with tolerance of the desert climate that allows for cellular respiration and development through phenological events. The duration of a plants phenological
