Backyard Discovery Suggests Ants Disperse Oak Galls, Not Just Seeds
Penn State and SUNY researchers, sparked by an 8-year-old’s backyard observation, report that oak galls formed by gall wasps can be collected and carried by ants just like seeds. The study reveals a three-way interaction among ants, oaks, and wasps, with the kapéllo cap on galls releasing free fatty acids similar to seed elaiosomes, attracting ants to disperse the galls. This finding broadens our understanding of forest biodiversity and overlooked ecological interactions.
