Last month our lab member, Kasia Kondrat defended her master’s thesis on Drivers of intraspecific variation in fecundity in rowan. This study investigated the factors influencing fecundity using a 22-year fruit-count dataset from 167 individual trees. Findings highlighted diameter at breast height (DBH) as the best size proxy for standardizing fecundity, and light availability played a major role in rowan’s fecundity. Congratulations Kasia!
