Do tributary streams contribute significantly to the transport of faecal pellets in large rivers?
Faecal pellets (FPs) produced by suspension feeders, notably larval blackflies (Diptera: Simuliidae), contribute significantly to the conversion and transport of organic matter in northern rivers. In this study we investigated the relative contribution of tributaries to the flux of FPs in a 7(th) or...
