This National Science Foundation (NSF) Biological Sciences program (CFDA 47.074) Project Grant, awarded to Georgetown University on February 15, 2025 for $175,064, will fund a collaborative research study on the impacts of periodical cicada emergence events on forest ecosystems. The researchers will examine how these periodic "biomass pulses" affect the foraging behaviors and population dynamics of ants, a highly abundant group of terrestrial invertebrates that provide critical ecosystem services. The study will utilize a range of field observation and experimental techniques to document the indirect effects that shifts in ant foraging may have on seed dispersal, scavenging, and aphid-protection services. Stable isotope analysis will also be used to assess trophic shifts among ant communities in response to the cicada resource pulses. In addition to advancing scientific understanding of trophic ecology during nutrient pulse events, the project includes an educational outreach component to train teachers on engaging students in cicada-focused learning activities across the Eastern U.S. regions where these periodic insect emergences occur.
