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 […]

Kathleen Schaeffer Prior to the 19th century, much of the Chihuahuan Desert was made up of perennial desert grasslands, however these grasslands have been greatly reduced by shrub encroachment, which has ultimately led to the shrub dominated landscapes we see today. In the early 2000s, local land managers began implementing large scale shrub removal that

Tweedie1 1System Ecology Lab, University of Texas at El Paso, El Paso Texas To understand ecosystem change over a range of spatial and temporal scales and levels of biological organization and interaction, multiple streams of ecological data need to be collected, integrated, and analyzed. However,

Julie Bethany Rakes Predatory bacteria constitute a guild of heterotrophs specialized in obtaining resources for growth from the live bacteria they prey upon. Its members have been isolated from many environments and are phylogenetically diverse, each having evolved their mode of life independently. We report on a novel type of obligatory predatory bacterium, Candidatus Cyanoraptor
