MANAGING STREAMS FROM THE OUTSIDE IN
Environmental regulation tends to focus on structural metrics of ecosystem integrity, which are not always sensitive to stream and riparian alterations. Functional metrics, such as the flow of carbon and nitrogen through the food web, likely paint a better picture of what is occurring in the stream and can be more sensitive to stream degradation. Here, we present a novel technique, using leaf litter enriched with 13C and 15N to trace the pathways of carbon and nitrogen transfer through stream food webs. Our results show that litter species influences the amount and timing of carbon and nitrogen assimilation by invertebrates. Some litter species contribute relatively more energy to microbial pathways, whereas others fuel macroscopic food webs. We demonstrate how alterations to stream and riparian condition influence the pathways of carbon and nitrogen flow through the food web and how these pathways may be more sensitive to degradation than conventional structural metrics of stream assessment. Our data highlight the need for a diversity of litter species to provide carbon and nitrogen resources for invertebrates throughout their life cycles.
