Journal ArticleDOI
Comparison of five modelling techniques to predict the spatial distribution and abundance of seabirds
Steffen Oppel,Ana Meirinho,Iván Ramírez,Beth Gardner,Allan F. O'Connell,Peter I. Miller,Maite Louzao,Maite Louzao +7 more
TL;DR: In this article, the authors compare the performance of five modelling techniques (generalised linear models, generalised additive models, Random Forest, boosted regression trees, and maximum entropy) to predict the distribution of Balearic Shearwaters (Puffinus mauretanicus) along the coast of the western Iberian Peninsula.
Journal ArticleDOI
Important Bird and Biodiversity Areas (IBAs): the development and characteristics of a global inventory of key sites for biodiversity
Paul F. Donald,Lincoln Fishpool,Ademola Ajagbe,Leon Bennun,G. Bunting,Ian J. Burfield,Stuart H. M. Butchart,Sofia Capellan,Michael J. Crosby,Maria P. Dias,David Diaz,Michael I. Evans,Richard Grimmett,Melanie Heath,Victoria R. Jones,Benjamin G. Lascelles,Jennifer C. Merriman,Mark O’Brien,Iván Ramírez,Zoltan Waliczky,David C. Wege +20 more
TL;DR: A review of the development and spread of the IBA concept since it was launched by BirdLife International (then ICBP) in 1979 and examine some of the characteristics of the resulting inventory can be found in this article.
Journal ArticleDOI
Foraging plasticity in a pelagic seabird species along a marine productivity gradient
TL;DR: There was a significant positive correlation between the percentage of short foraging trips in the different breeding sites and the concentration of chlorophyll-a in the waters surrounding those sites, indicating that birds adapted their modes of predation to cope with the diverse dis- tribution of their prey items.
Journal ArticleDOI
A prioritised list of invasive alien species to assist the effective implementation of EU legislation
Carles Carboneras,Piero Genovesi,Montserrat Vilà,Tim M. Blackburn,Martina Carrete,Miguel Clavero,Bram D'hondt,Jorge F. Orueta,Belinda Gallardo,Pedro Geraldes,Pablo González-Moreno,Richard D. Gregory,Wolfgang Nentwig,Jean-Yves Paquet,Petr Pyšek,Petr Pyšek,Wolfgang Rabitsch,Iván Ramírez,Riccardo Scalera,José Luis Tella,Paul Walton,Robin M. Wynde +21 more
TL;DR: In this paper, the authors developed a simple method to systematically rank IAS according to their maximum potential threat to biodiversity in the EU, and identified 1,323 species as potential candidates for listing, and evaluated them against their invasion stages and reported impacts, using information from databases and scientific literature.
Journal ArticleDOI
Oceanographic characteristics of areas used by Cory's shearwaters during short and long foraging trips in the North Atlantic
Vitor H. Paiva,Vitor H. Paiva,Pedro Geraldes,Iván Ramírez,Ana Meirinho,Stefan Garthe,Jaime A. Ramos +6 more
TL;DR: Core feeding areas and areas of foraging overlap between different populations should be important to inform conservation management measures, such as the definition of Marine Important Bird Areas for seabirds over the North Atlantic.
