Figure 2. Average number of Kelp Gull pairs (bars) and average Southern Oscillation Index (line) at each summer in Admiralty Bay. Error bars are standard errors. Figure 4. Variation of Temperature as a response to Southern Oscillation Index (SOI). greater number of ice-free areas, but there were few breeders as a function of high SOI. The variations of El-Niño have an influence on Antarctic waters and can affect the animal population and ecological processes within populations. In the short term such effect reduces the numbers of breeding pairs and as a consequence the breeding success of the population. In the long term, recruitment rates can be affected, and it may imply in lower growth rates. Figure 3. Variation of average number of Kelp Gull pairs in response to the average Southern Oscillation Index. Trend line is a quadratic function represented by the equation Y = 1.6*X – 1.75*X 2 +6.34; R 2 = 0.62. (Lescroël et al., 2009; Beaulieu et al., 2010). One explanation for such changes is the increasing influence of ENSO in Antarctica (Croxall et al., 2002). The 2009/10 summer was the coldest in the last decades (INPE, 2010). We verified in surveys that there were few ice-free areas, reducing the availability or suitability of breeding habitat, but the subsequent summer (2010/11) was warmer providing a Acknowledgements This work integrates the National Institute of Science and Technology Antarctic Environmental Research (INCT- APA) that receives scientific and financial support from the National Council for Research and Development (CNPq process: n° 574018/2008-5) and Carlos Chagas Research Support Foundation of the State of Rio de Janeiro (FAPERJ n° E-16/170.023/2008).
