Terrestrial–aquatic linkages in spring-fed and snowmelt-dominated streams

open access: yesJournal of Freshwater Ecology, 2017
The importance of trophic linkages between aquatic and terrestrial ecosystems is predicted to vary as a function of subsidy quantity and quality relative to in situ resources. To test this prediction, I used multi-year diet data from Bonneville cutthroat
