“…The distances between the colonies ranged from 10 to 90 km. Arctic Tern foraging ranges are typically <10 km from the colony (Rock et al 2007, Thaxter et al 2012, and so the foraging ranges of individuals from these colonies are not likely to overlap much. Colonies also varied in size, ranging from 50 to 10 000 pairs.…”

“…It is one of the most abundant seabirds breeding in northeast Britain (Harris & Wanless 2004) yet a recent review of data relevant to the foraging ranges of British seabirds revealed that less is known of the feeding areas used by Puffins than by most other species and more information is urgently needed (Thaxter et al 2012). One reason for this knowledge gap is that Puffins are sensitive to disturbance, particularly handling (Wernham 1993, Rodway et al 1996, Harris & Wanless 2011 and, like the Tufted Puffin F. cirrhata (Whidden et al 2007), seem intolerant of back-mounted devices (pers obs).…”

“…Currently, site-selection of MPAs for safeguarding seabirds has been proposed using different approaches (e.g. protection of areas associated with breeding colonies and aggregations of non-breeding birds, and protection of migratory bottlenecks) (Grecian et al 2012;Thaxter et al 2012). We believe that including sites that comprise geographic range of species with high extinction risk, as those showed here, could increase spatial prioritization effectiveness avoiding species losses.…”

Modeling Extinction Risk for Seabirds in Brazil

Species extinction risk is associated with intrinsic features such as body mass, geographic range size and diet, and also with external threats, mainly anthropogenic pressure. Current biological knowledge on seascapes still falls behind knowledge from terrestrial ecosystems, and understanding the pathways to extinction for declining groups, such as seabirds, is of paramount importance. Here we provide the first estimates of seabird extinction risk derived from regressive models associating species intrinsic features and external threats, and evaluation of effectiveness of marine protected areas (MPA). We aimed to: (i) understand how intrinsic and external variables interact to set pathways to seabird extinction; (ii) define which variables are most important; (iii) evaluate the geographic structure of extinction risk; and (iv) evaluate the effectiveness of Brazilian MPAs in representing species at high and low risk. We used classification tree to model extinction risk and random forest to evaluate the importance of each variable. Our models were accurate to predict relative extinction risk of threatened species. Breeding range size and threat from fishing vessel were the most important correlates of extinction risk. Brazilian MPAs are not effective to protect seabirds and are short to cover a minimum of 10% of species ranges. We show that correlates of extinction risk act in a synergistic way and suggest that conservation of seabirds in Brazil should be considered high priority given their low current level of protection.
