Although snow petrels are ubiquitous around the Antarctic, population estimates of this not so charismatic‚ÄövÑvp top predator are generally limited. Such information is highly valuable for the monitoring and management of Antarctic and Southern Ocean ecosystems, especially in a climate change context. There is a need to complement long‚Äö-term temporal demographic information obtained at a limited number of monitoring sites with spatial distribution data. Systematic surveys of snow petrels and Wilson's storm petrels were undertaken at Casey (2002-2003) and Mawson (2004-2005) in order to provide better regional population estimates and test the performance of predictive distribution models based on topographic and substrate variables for refining such estimates. As habitat selection modelling is rarely used in Antarctic regions, methodological developments focus on dealing with the peculiarities of a semi-colonial hollow-nesting species, testing habitat selection modelling approaches and comparing the output ...
