A Benthic Subsidy Amplifies The Impact Of Planktivorous Fish In Lake Food Webs
In many studies, littoral and benthic processes are thought to be coupled to pelagic food webs primarily by ontogenetic habitat shifts of planktivorous fish. Many pelagic fish species begin life in the littoral zone, migrating to open water as they age. However, recent analyses of stable isotope ratios have revealed that so-called
