AB  - Physiological changes were explored in fatty acids (FA) and carbohydrate (CHO) 
      composition in the shredder Calamoceras marsupus larvae (Trichoptera) and leaf 
      litter (C. marsupus food) exposed to copper and uranium under natural and 
      experimental conditions. We measured FA and CHO content in leaf litter and larvae 
      specimens from reference and impacted streams, and exposed for 5 weeks to four 
      realistic environmental concentrations of copper (35 mug L(-1) and 70 mug L(-1)) 
      and uranium (25 mug L(-1) and 50 mug L(-1)). Regarding FA, (1) leaf litter had a 
      reduced polyunsaturated FA (PUFA) content in metal treatments, s (14 to 33% of 
      total FA), compared to natural conditions (>/=39% of total FA). Leaf litter exposed 
      to uranium also differed in saturated FA (SFA) composition, with lower values in 
      natural conditions and higher values under low uranium concentrations. (2) C. 
      marsupus had/showed low PUFA content under Cu and U exposure, particularly in 
      high uranium concentrations. Detritivores also decreased in PUFA under exposure 
      to both metals, particularly in high uranium concentrations. On the other hand, 
      (1) microorganisms of the biofilm colonizing leaf litter differed in CHO 
      composition between natural (impacted and reference) and experimental conditions, 
      with glucose and galactose being consistently the most abundant sugars, found in 
      different amounts under copper or uranium exposure; (2) CHO of detritivores 
      showed similar high galactose and fucose concentrations in contaminated streams 
      and high copper treatments, whereas low copper treatment showed distinct CHO 
      profiles, with higher mannose, glucose, arabinose, and fucose concentrations. Our 
      study provides evidence of metal exposure effects on FA and CHO contents at 
      different trophic levels, which might alter the quality of food flow in trophic 
      webs.
