Research: Food webs and invertebrate communities have been thoroughly studied in small streams, but there has been relatively little research done on the trophic linkages between subsurface and surface communities (i.e., within hyporheic habitats).  Hyporheic habitats may play a major role in shaping stream food webs and are likely very susceptible to warming temperatures. Climate change and resource development could alter the trophic linkages between surface and subsurface habitats upon which stream food webs depend.  Understanding these linkages better, in the face of increasing resource development and climate change, will help inform aquatic resource management.
            Our study objectives are to determine 1) how water temperature influences invertebrate community assemblage, density, and diversity at the stream surface-subsurface interface, and 2) how hyporheic communities and processes influence stream food webs.
