Experimental freshwater macrocosms, with increasing densities of four species of macroinvertebrate\ndetritivores belonging to two functional groups (shredders and scrapers), were set up outdoors. The litter bag\ntechnique was used to assess decomposition rates of alder leaves. Indirect effects of increasing density of macroinvertebrates\non phytoplankton standing crop in the water column were investigated by analysing Chlorophyll a\nconcentration. Decomposition rate increased as animal density increased, although a continuous increase in detritivores\ndensity resulted in a discrete, step-wise increase of the decomposition rates. Animal colonisation followed an\nexponential pattern in low-medium density treatments versus a typical 'bell-shape' curve in high density treatments;\nanimals started to leave the consumed patches when about 60% of the initial leaf mass was lost (35th day in highdensity\ntreatments). Diversity (Hs) of the simplified detritivore community decreased as decomposition proceeded,\nwith a dominance of shredders during the last phase of decomposition. Faster decomposition rate of detritus in\nthe benthic compartment lead to a higher microalgae standing crop in the water column emphasising the role of\nallochthonous detritus as a source of nutrients for algae primary production in coastal freshwater ecotones."@en ; prodottidellaricerca:prodottoDi istituto:CDS069 ; pubblicazioni:autoreCNR unitaDiPersonaleInterno:MATRICOLA8980 . @prefix parolechiave: . prodotto:ID228431 parolechiave:insiemeDiParoleChiave . ns10:ID596413 pubblicazioni:rivistaDi prodotto:ID228431 . parolechiave:insiemeDiParoleChiaveDi prodotto:ID228431 .
