Top-down vs. bottom-up control on vegetation composition in a tidal marsh depends on scale

Abstract: The relative impact of top-down control by herbivores and bottom-up control by environmental conditions on vegetation is a subject of debate in ecology. In this study, we hypothesize that top-down control by goose foraging and bottom-up control by sediment accretion on vegetation composition within an ecosystem can co-occur but operate at different spatial and temporal scales. We used a highly dynamic marsh system with a large population of the Greylag goose (Anser anser) to investigate the potential importanc… Show more

“…The relative importance of top-down control by herbivores and bottom-up control by environmental conditions on primary production within ecosystems has been the subject of a long-standing debate in ecology (Elschot et al, 2017;Gruner et al, 2008;Hunter & Price, 1992). Environmental conditions may determine the direction and magnitude of top-down and bottom-up forces that control freshwater communities and influence species diversity (Thompson & Townsend, 2005;Werner & Matthiessen, 2013).…”
