dc.description.abstract Gammarus minus has both cave and surface forms that differ considerably in their morphology. We experimentally compared the ability of these two forms to consume leaves and influence the activity of the microbial films associated with leaves. Both forms of G. minus were effective leaf shredders, and were equally efficient at converting leaves to small particles. We found little relationship between amphipod size and the rate at which they shredded leaves. Both forms of G. minus stimulated the respiration rate of microbes associated with leaves by 32–52%. Cave forms of G. minus had a 15% greater stimulatory effect on microbial respiration. The stimulatory effect of G. minus on microbial respiration is evident in cave streams as well as in the laboratory. It appears that G. minus plays a particularly important role in cave systems by converting leaves to fine particles and stimulating microbial films which are important foods for many cave animals. en
