AVOTREX: A Global Dataset of Extinct Birds and Their Traits
Sayol, Ferran; Wayman, Joseph P.; Dufour, Paul; Martin, Thomas E.; Hume, Julian P.; Jørgensen, Maria Wagner; Martínez‐Rubio, Natàlia; Sanglas, AriadnaMotivation Human activities have been reshaping the natural world for tens of thousands of years, leading to the extinction of hundreds of bird species. Past research has provided evidence of extinction selectivity towards certain groups of species, but trait information is lacking for the majority of clades, especially for prehistoric extinctions identified only through subfossil remains. This incomplete knowl...
A global analysis of avian island diversity–area relationships in the Anthropocene
Matthews, Thomas J.; Wayman, Joseph P.; Whittaker, Robert J.; Cardoso, Pedro; Hume, Julian P.; Sayol, Ferran; Proios, Konstantinos; Martin, Thomas E.Research on island species–area relationships (ISAR) has expanded to incorporate functional (IFDAR) and phylogenetic (IPDAR) diversity. However, relative to the ISAR, we know little about IFDARs and IPDARs, and lack synthetic global analyses of variation in form of these three categories of island diversity–area relationship (IDAR). Here, we undertake the first comparative evaluation of IDARs at the global scal...
A tale of two species: the importance of native ecosystems for long-term conser...
Rebelo, Guilherme R.V.; Soares, Filipa C.; Panisi, Martina; dos Santos, Yodiney; Bird, Tania L.F.; Sinclair, Frazer; M. Palmeirim, JorgeSince it was first described in 1901, the Príncipe thrush Turdus xanthorhynchus has been rare and restricted to the native forest in the south of Príncipe Island. The Obô giant land snail Archachatina bicarinata, however, was widespread across the island and at least locally abundant until the 1990s. Since then its population has collapsed, and now, like the thrush, it is also restricted to the native forest in...
Threatened and extinct island endemic birds of the world: Distribution, threats...
Matthews, Thomas J.; Wayman, Joseph P.; Cardoso, Pedro; Sayol, Ferran; Hume, Julian P.; Ulrich, Werner; Tobias, Joseph A.; Soares, Filipa C.AIM: The world's islands support disproportionate levels of endemic avian biodiversity despite suffering numerous extinctions. While intensive recent research has focused on island bird conservation or extinction, few global syntheses have considered these factors together from the perspective of morphological trait diversity. Here, we provide a global summary of the status and ecology of extant and extinct isl...
Niche differences may reduce susceptibility to competition between native and n...
Soares, Filipa C.; Leal, Ana I.; M. Palmeirim, Jorge; F. De Lima, RicardoAim Few bird extinctions on oceanic island have been attributed to competition with non-native species, even though it might be an overlooked driver of biodiversity loss. We evaluate the potential competition between native and non-native island bird species, identifying species and island characteristics that enhance it and may promote future extinctions. Location Seventy-three (>100 km2) oceanic islands world...
