AB  - Seabirds integrate bioaccumulative contaminants via food intake and have revealed 
      geographical trends of contamination in a variety of ecosystems. Pre-fledging 
      seabird chicks are particularly interesting as bioindicators of chemical 
      contamination, because concentrations in their tissues reflect primarily dietary 
      sources from the local environment. Here we measured 14 trace elements and 18 
      persistent organic pollutants (POPs) in blood of chicks of skuas that breed in 
      four sites encompassing a large latitudinal range within the southern Indian 
      Ocean, from Antarctica (Adelie Land, south polar skua Catharacta maccormicki), 
      through subantarctic areas (Crozet and Kerguelen Islands, brown skua 
      C. lonnbergi), to the subtropics (Amsterdam Island, C. lonnbergi). Stables 
      isotopes of carbon (delta(13)C, feeding habitat) and nitrogen (delta(15)N, trophic 
      position) were also measured to control for the influence of feeding habits on 
      contaminant burdens. Concentrations of mercury (Hg) and selenium (Se) were very 
      high at all the four sites, with Amsterdam birds having the highest 
      concentrations ever reported in chicks worldwide (4.0 +/- 0.8 and 
      646 +/- 123 mug g(-1) dry weight, respectively). Blood Hg concentrations showed a 
      clear latitudinal pattern, increasing from chicks in Antarctica to chicks in the 
      subantarctic and subtropical islands. Interestingly, blood Se concentrations 
      showed similar between-population differences to Hg, suggesting its involvement 
      in protective mechanisms against Hg toxicity. Chicks' POPs pattern was largely 
      dominated by organochlorine pesticides, in particular DDT metabolites and 
      hexachlorobenzene (HCB). Skua chicks from subantarctic islands presented high 
      concentrations and diversity of POPs. By contrast, chicks from the Antarctic site 
      overall had the lowest concentrations and diversity of both metallic and organic 
      contaminants, with the exception of HCB and arsenic. Skua populations from these 
      sites, being naturally exposed to different quantities of contaminants, are 
      potentially good models for testing toxic effects in developing chicks in the 
      wild.
