Abstract: 3 tables. 1 figure. ["Instead, compound concentrations were correlated most closely with thallus size, with small rather than large thalli having the highest conditions of the two compounds. Inasmuch as lichen secondary compounds serve a defensive role against microorganisms and herbivores, our results suggest that small, juvenile thalli are better defended than more mature thalli." Specimens for analysis came from West Virginia.]
