Oceanographic and climatic factors differentially affect reproduction performance of Antarctic skuas

  title={Oceanographic and climatic factors differentially affect reproduction performance of Antarctic skuas},
  author={Steffen Hahn and Klaus Reinhardt and Markus S. Ritz and Tim Janicke and Diego Montalti and H U Peter},
We studied how environmental conditions affect reproduction in sympatric skua species that differ in their reliance on marine resources: the exclusively marine foraging south polar skua Catharacta maccormicki, the terrestrially foraging brown skua C. antarctica lonnbergi and mixed species pairs with an intermediate diet. Egg size, clutch asymmetry and hatching dates varied between species and years without consistent patterns. In the south polar skuas, 12 to 38% of the variation in these… CONTINUE READING
