Abstract

The effect of leaf species composition on decomposition patterns was examined in a coastal plain stream. Red maple leaves (Acer rubrum) decomposed at the same rate separately or when mixed with cypress leaves (Taxodium distichum). Cypress addition increased structural integrity but its effects differed between sites with different hydrologic regimes. Invertebrate communities varied slightly between mixed and single species packs, however invertebrates did not appear to be the primary agent of decomposition. Mixed species packs may be an alternative method to fine mesh bags for studying processing of small, narrow leaves in a more realistic manner.
