Its aim is to improve the protection of marine birds in the peninsular coast.

The routes, distribution and behaviour of the marine birds can be studied in detail thanks to global positioning systems GPS. This project will combine the information from the global positioning systems of the Spanish fishing fleet with the database of the UB-IRBio team on the habitat and ecology of Cory's shearwater Calonectris diomedea , the Balearic shearwater Puffinus mauretanicus , the Yelkouan shearwater Puffinus yelkouan , Audouin's gull Larus audouinii , and the Yellow-legged gull L michahellis.

Retrieved September 21, from www. In Mediterranean colonies, these marine birds do We compared the variation in species-specific and community-level responses to these habitat features, including for rare species, and we predicted species abundance across the study area.

Social channels

While several protected species used the study area in summer during their breeding season, estimated abundance and observed diversity were highest for nonbreeding species in winter. Distance to shore was the most common significant predictor of abundance, and thus useful in estimating the potential exposure of marine birds to offshore development.

In many cases, our expectations based on feeding ecology were confirmed, such as in the first winter season, when bottom-feeders associated significantly with the three static covariates distance to shore, slope, and sediment grain size , and surface-feeders associated significantly with two dynamic covariates SST, primary productivity.

However, other cases revealed significant relationships between static covariates and surface-feeders e. More generally, we found wide interannual, seasonal, and interspecies variation in habitat relationships with abundance.
