This study integrates a wide range of ecological data into a comprehensive framework dataset describing the functional and structural dynamics of small streams located under different climatic conditions in Spain. Standing stocks of particulate organic matter, algal biomass and macroinvertebrate communities are examined with comparisons between Atlantic streams of North-West Spain and Mediterranean temporary streams of the island of Majorca. This dataset, which links potential food sources to consumer dynamics, allows explanation of the structural and functional variability exhibited by these two fluvial systems. Results indicate that the differences in the dynamics of community trophic structure of the two types of streams are a reflection of their hydrological and climatic characteristics.
