  abstract = {{T}he lack of knowledge about highly anthropised tropical ecosystems poses a problem for their conservation. {U}sing carbon and nitrogen stable isotopes, we studied the food web structure of the estuarine ecotone of the {S}anta {C}ruz {C}hannel ({SCC}), which constitutes a critical habitat for many socio-economically important species in northeast {B}razil. {T}herefore, we assessed the spatial (estuary/coast) and seasonal (dry/rainy) isotopic variation of basal food sources, invertebrates and fishes. {W}e also used {B}ayesian mixing models to trace the origin (estuary vs coast) of the organic matter sources supporting {SCC} fishes food webs according to their feeding habits. {W}e found a wide range of delta {C}-13 and delta {N}-15 values for basal sources, invertebrates, and fish in coastal and estuarine envi-ronments, but isotopic compositions showed greater variability in the estuary. {T}his illustrated the heterogeneity of primary producers and sources in estuaries, intensified by {SCC} morphology, as both accesses to the sea provide strong mixing between riverine and marine inputs. {A}dditionally, we found differences between fish isotope compositions according to their guilds. {C}oastal basal sources significantly support zoobenthivorous, piscivorous and zooplanktivorous fish estuarine food webs. {C}onversely, detritivores are supported by enriched sources of organic matter, especially during the dry season, which may be derived from terrestrial inputs. {A}s contaminated land-based inputs can affect food webs and coastal fisheries, developing a management plan that includes all interconnected habitats is necessary.},
