Quantifying the unrecorded loss of avian phylogenetic diversity
Faurby, Søren; Matthews, Thomas; Triantis, K.; Sayol, F.ABSTRACT: Humans have drastically reduced avian diversity, with the majority of extinctions occurring on islands. Previous studies have quantified various aspects of this decline, including both taxonomic and phylogenetic diversity loss due to recorded extinctions. Other studies have estimated that unrecorded island bird extinctions – those that left no known fossil evidence – may represent hundreds of addition...
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...
Megafauna decline have reduced pathogen dispersal which may have increased emer...
Doughty, Christopher E.; Prys-Jones, Tomos O.; Faurby, Søren; Abraham, Andrew J.; Hepp, Crystal; Leshyk, Victor; Fofanov, Viacheslav Y.Made available in DSpace on 2020-12-12T02:39:59Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-08-01; The Late Quaternary extinctions of megafauna (defined as animal species > 44.5 kg) reduced the dispersal of seeds and nutrients, and likely also microbes and parasites. Here we use body-mass based scaling and range maps for extinct and extant mammal species to show that these extinctions led to an almos...
Conceptual and empirical advances in Neotropical biodiversity research
Antonelli, Alexandre; Ariza, María A.; Albert, James Spurling; Andermann, Tobias; Azevedo, Josué A.R.; Bacon, Christine D.; Faurby, SørenThe unparalleled biodiversity found in the American tropics (the Neotropics) has attracted the attention of naturalists for centuries. Despite major advances in recent years in our understanding of the origin and diversification of many Neotropical taxa and biotic regions, many questions remain to be answered. Additional biological and geological data are still needed, as well as methodological advances that ar...
