AB  - Body mass–abundance (MN) allometries provide a key measure of community structure, and deviations from scaling predictions could reveal how crossecosystem subsidies alter food webs. For 31 streams across the UK, we tested the hypothesis that linear loglog MN scaling is shallower than that predicted by allometric scaling theory when top predators have access to allochthonous prey. These streams all contained a common and widespread top predator (brown trout) that regularly feeds on terrestrial prey and, as hypothesised, deviations from predicted scaling increased with its dominance of the fish assemblage. Our study identifies a key beneficiary of crossecosystem subsidies at the top of stream food webs and elucidates how these inputs can reshape the sizestructure of these ‘open’ systems.
