Streams in north temperate deciduous forests receive a peak in allochthonous inputs during autumn leaf fall. Honeysuckle (Lonicera maackii) is an invasive terrestrial plant that has become established in riparian zones in southwestern
We found that honeysuckle leaves decomposed 1.5 times faster than maple leaves and that this difference was significant using a 95% confidence interval. An Analysis of Similarity (ANOSIM) for macroinvertebrates revealed that the abundances of families colonizing maple and honeysuckle leaf packs were not significantly different. Benthic macroinvertebrates did not appear to differentiate between leaves of the two species. Honeysuckle must decompose more rapidly than maple due to differences in some other mechanism such as microbial decomposition or fragmentation due to water flow. If honeysuckle is being decomposed by microbes this may alter the dynamics of the microbial loop, whereas if honeysuckle decomposition occurs at a faster rate because of fragmentation due to water flow, there could be a temporary pulse in food supply for filter feeders.
