The importance of Portuguese Continental Shelf Waters to Balearic Shearwaters r...
Araújo, Hélder; Bastos-Santos, Jorge; Rodrigues, Pedro Correia; Ferreira, Marisa; Pereira, Andreia; Henriques, Ana Catarina; Monteiro, Sílvia S.The Balearic shearwater Puffinus mauretanicus is one of the most threatened seabirds in the world. To evaluate the abundance and distribution of Balearic Shearwaters in Portuguese Continental Shelf Waters, during the post-breeding period when migrating birds are outside the Mediterranean Sea, we conducted 5 aerial surveys between 2010 and 2014 (21 survey days covering 62,716 km2). Following a line transect meth...
Influence of oceanographic variables on seabird distributions
Rodrigues, Pedro CorreiaThe development of effective conservation strategies for seabirds depends largely on the knowledge of species distributions and their relationship with the marine environment. Understanding species responses to environmental changes, and particularly shifts in their range size and distribution, is therefore a major current challenge for ecologists and conservationists. The capacity of species to shift distribut...
