Food Web Subsidies In Intermittent Streams: Implications For Small Isolated Populations Of Native Brook Trout, Jennifer Lauren Courtwright

Masters Theses, 2010-2019

Recent studies in perennial streams have shown that reduction of stream-side vegetation can reduce terrestrial invertebrate inputs to streams and can cause trophic cascades throughout aquatic and terrestrial food webs; however, aquatic-terrestrial food web linkages have not been studied in intermittent streams. Food webs in intermittent streams may be even more dependent on terrestrial invertebrate fluxes because of limited aquatic invertebrate resources; thus intermittent streams may represent unique systems that warrant special attention. The objective of this research was first to quantify the abundance, biomass, and energetic content of available brook trout and insectivorous stream-side predator invertebrate resources in two …
