| Abstract: | The goal of this study was to understand how organic matter processing varied over space and time in the context of an elevational and stream size gradient. We investigated in-stream leaf decomposition in different habitat patches using leaf species that varied in their speed of processing along a first fourth-order stream gradient. |

| Methods/Experimental Design: |
Rhododendron, white oak, and tulip poplar
leaves were collected just prior to abscission, air-dried, and placed in
large mesh bags. Bags were placed in stream, collected monthly, and
brought to lab. Leaves were washed of debris and invertebrates, oven
dried, weighed and ground. Three sub-samples were taken and ashed at
550C to determine ash-free-dry-mass (AFDM).
