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...
Assessing taxonomic and functional change in British breeding bird assemblages ...
Wayman, Joseph P.; Sadler, Jonathan P.; Pugh, Thomas A. M.; Martin, Thomas E.; Tobias, Joseph A.; Matthews, Thomas J.AIM: The aim was to identify the primary drivers of compositional change in breeding bird assemblages over a 40-year period. LOCATION: Britain. TIME PERIOD: From 1970 to 2010. MAJOR TAXA STUDIED: Birds. METHODS: Using morphological trait measurements and a dataset of presence-absence data for British breeding birds surveyed in 10 km × 10 km hectads during two time periods, we calculated temporal taxonomic and f...
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...
Identifying the Drivers of Spatial Taxonomic and Functional Beta-Diversity of B...
Wayman, Joseph P.; Sadler, Jonathan P.; Pugh, Thomas A. M.; Martin, Thomas E.; Tobias, Joseph A.; Matthews, Thomas J.Spatial variation in community composition may be driven by a variety of processes, including environmental filtering and dispersal limitation. While work has been conducted on the relative importance of these processes on various taxa and at varying resolutions, tests using high-resolution empirical data across large spatial extents are sparse. Here, we use a dataset on the presence/absence of breeding bird sp...
