Extinction selectivity obscures patterns of trait-dependent endangerment in Columbiformes

Understanding how extinction has occurred in the recent past is crucial to unravel its main drivers as well as to implement effective conservation practices to minimize global biodiversity loss. It has long been hypothesized that extinction risk is not randomly distributed among traits of species. However, the actual traits making species more prone to extinction may have been overlooked because already extinct species are often not considered in comparative analyses of extinction risk. We characterized the drivers of extinction in a cosmopolitan bird clade, including Holocene and contemporary extinctions potentially related to human impacts, and provided evidence of an ‘extinction selectivity’ in species traits. We constructed a new phylogenetic hypothesis of the Columbiformes, a cosmopolitan bird clade consisting of 33 recently extinct and 351 extant species. Then, we integrated data on geography, behaviour, and morphology to reveal the drivers of extinction risk. We used phylogenetic..., Here, we present a database for the Columbiformes clade encompassing a list of 384 species (including 351 extant and 33 extinct species) with information about the threat status (based on the IUCN Red List), and behavioural, geographical, and morphological trait information. Specifically, for behavioural traits, we gathered information on flight ability, habitat, migratory behaviour, and ground foraging from published sources. For morphological traits, we focused on measurements of beak length from culmen, beak width, tarsus length, wing length, Kipp’s distance, tail length (all in mm), and body mass (in grams). Finally, for geographical traits we recorded its geographical distribution and whether the species was an island endemic. 
To achieve complete coverage of species traits, we employed an inference approach to estimate missing data for behavioural and morphological traits. Specifically, for behavioural traits, we inferred habitat (n=17; 4.4%) and ground-foraging (n=21;5.4%) using ..., , # Data from: Extinction selectivity obscures patterns of trait-dependent endangerment in Columbiformes
