      description => protected'Climate change can decouple resource supply from consumer demand, with the p
         otential to create phenological mismatches driving negative consequences on 
         fitness. However, the underlying ecological mechanisms of phenological misma
         tches between consumers and their resources have not been fully explored. He
         re, we use long-term records of aquatic and terrestrial insect biomass and e
         gg-hatching times of several co-occurring insectivorous species to investiga
         te temporal mismatches between the availability of and demand for nutrients 
         that are essential for offspring development. We found that insects with aqu
         atic larvae reach peak biomass earlier in the season than those with terrest
         rial larvae and that the relative availability of omega-3 long-chain polyuns
         aturated fatty acids (n-3 LCPUFAs) to consumers is almost entirely dependent
          on the phenology of aquatic insect emergence. This is due to the 4- to 34-f
         old greater n-3 LCPUFA concentration difference in insects emerging from aqu
         atic as opposed to terrestrial habitats. From a long-sampled site (25 years)
          undergoing minimal land use conversion, we found that both aquatic and terr
         estrial insect phenologies have advanced substantially faster than those of 
         insectivorous birds, shifting the timing of peak availability of n-3 LCPUFAs
          for birds during reproduction. For species that require n-3 LCPUFAs directl
         y from diet, highly nutritious aquatic insects cannot simply be replaced by 
         terrestrial insects, creating nutritional phenological mismatches. Our resea
         rch findings reveal and highlight the increasing necessity of specifically i
         nvestigating how nutritional phenology, rather than only overall resource av
         ailability, is changing for consumers in response to climate change.' (1740 chars)
