Analyses are based on standardized ship-based surveys with oceanographic sampling, and equipment of breeding birds with data loggers. The Northern Gannet as focal species was most abundant. At-sea totals for the Southern Gulf proved regional and international importance for several species. New insights into links between seabirds and at-sea habitats were gained using generalized additive models (GAMs). Colony location as spatial constraint showed strong influence on breeding species. Water mass indicators were important predictors of seabird distribution. Northern Gannets were highly associated with cetaceans which had a strong influence on foraging behavior and general distribution of Gannets. Breeding Gannets from Bonaventure feeding on Atlantic Mackerel showed short, high speed and shallow V-shaped dives in response to this type of prey. 4950 https://nbn-resolving.org/urn:nbn:de:gbv:8-diss-120790$xR$3Volltext$534 4961 https://macau.uni-kiel.de/receive/diss_mods_00012079 5051 590 5550 Atlantic Mackerel 5550 at-sea number 5550 cetacean 5550 data logger 5550 distribution 5550 diving 5550 foraging ecology 5550 Gulf of St. Lawrence 5550 habitat selection 5550 hotspot 5550 multi-species feeding association 5550 Northern Gannet 5550 Northwest Atlantic 5550 primary productivity 5550 seabird 5550 spatial constraint 5550 water mass
