Data from: The importance of terrestrial subsidies in stream food webs varies along a stream size gradient

Sarah M. Collins, Tyler J. Kohler, Steven A. Thomas, William W. Fetzer & Alexander S. Flecker
Cross system subsidies of energy and materials can be a substantial fraction of food web fluxes in ecosystems, especially when autochthonous production is strongly limited by light or nutrients. We explored whether assimilation of terrestrial energy varied in specific consumer taxa collected from streams of different sizes and resource availabilities. Since headwater streams are often unproductive, we expected that inputs from surrounding terrestrial systems (i.e. leaf litter, terrestrial invertebrates) would be a more important food...
