John Longino, Ph.D. (left), and Michael Branstetter, Ph.D., pose at a field site in Costa Rica, surrounded by lea litter-sifting equipment. Prior to litter-sifting methods, the ant genus Rasopone was known from only a handful of specimens. Large biodiversity inventory projects, with student teams sifting litter throughout Central America, produced nearly 800 specimens. Branstetter and Longino’s study on the genus, published in April 2020 in Insect Systematics and Diversity, would have been impossible without those projects. (Photo courtesy of John Longino, Ph.D.)
