In most studies of litter and soil fauna in the Luquillo Experimental Forest (LEF), tiny soil animals called 'Collembola' are an important group for ecosystem functioning because of their dominant abundance and their key responses to changes in disturbance, altitude and vegetation type. In Puerto Rico, collembolans are well known in comparison to other groups of soil arthropods. However, not all Collembola species from LEF have been identified. A University of Puerto Rico Ph.D. student Claudia Marcela Ospina-Sánchez under the guidance of US USDA Forest Service researcher Grizelle González studied the Collembola populations in a latitudinal gradient in LEF during 2014 and 2015. They identified 16 families, 37 genera and 60 species/morphospecies, and among these, 15 are new species to science. Using morphological differentiation, two new species were described and published in scientific peer review journals.
