Microinvertebrates Research 2 (IMAGE) University of Texas at El Paso Caption Jose A. Rivas, a doctoral candidate in The University of Texas at El Paso's Ecology and Evolutionary Biology program, looks through a microscope at a sample of rehydrated dust containing microinvertebrates. The dust was collected from trays on the roof of the Biology Building on campus. Rivas is part of a team of UTEP faculty and staff who published the first evidence of how wind moves waterborne microinvertebrates across vast expanses of arid desert.
