sampbias, a method for quantifying geographic sampling biases in species distribution data
Geo‐referenced species occurrences from public databases have become essential to biodiversity research and conservation. However, geographical biases are widely recognized as a factor limiting the usefulness of such data for understanding species diversity and distribution. In particular, differences in sampling intensity across a landscape due to differences in human accessibility...Zizka, Alexander ; Antonelli, Alexandre ; Silvestro, Daniele

raxmlGUI 2.0: A graphical interface and toolkit for phylogenetic analyses using RAxML
raxmlGUI is a graphical user interface to RAxML, one of the most popular and widely used softwares for phylogenetic inference using maximum likelihood. Here we present raxmlGUI 2.0, a complete rewrite of the GUI which seamlessly integrates RAxML binaries for all major operating systems with an intuitive graphical front‐end to...Edler, Daniel ; Klein, Johannes ; Antonelli, Alexandre ; Silvestro, Daniele

iucn_sim: a new program to simulate future extinctions based on IUCN threat status
The ongoing environmental crisis poses an urgent need to forecast the who, where and when of future species extinctions, as such information is crucial for targeting conservation efforts. Commonly, such forecasts are made based on conservation status assessments produced by the International Union for Conservation of Nature (IUCN). However, when...Andermann, Tobias ; Faurby, Søren ; Cooke, Robert ; Silvestro, Daniele ; Antonelli, Alexandre

Brain expansion in early hominins predicts carnivore extinctions in East Africa
While the anthropogenic impact on ecosystems today is evident, it remains unclear if the detrimental effect of hominins on co‐occurring biodiversity is a recent phenomenon or has also been the pattern for earlier hominin species. We test this using the East African carnivore fossil record. We analyse the diversity of...Faurby, Søren ; Silvestro, Daniele ; Werdelin, Lars ; Antonelli, Alexandre

outsider: Install and run programs, outside of R, inside of R
In many areas of research, product development and software engineering, analytical pipelines – workflows connecting output from multiple software – are key for processing and running tests on data. They can provide results in a consistent, modular and transparent manner. Pipelines also make it easier to demonstrate the reproducibility of...Bennett, Dominic ; Hettling, Hannes ; Silvestro, Daniele ; Vos, Rutger ; Antonelli, Alexandre

Exploring the Impact of Political Regimes on Biodiversity
National governments are the main actors responsible for mapping and protecting their biodiversity, but countries differ in their capacity, willingness, and effectiveness to do so. We quantify the global biodiversity managed by different regime types and developed a tool to explore the links between level of democracy and other key...Zizka, Alexander ; Rydén, Oskar ; Edler, Daniel ; Klein, Johannes ; Aronsson, Heléne …

Disproportionate extinction of South American mammals drove the asymmetry of the Great American Biotic Interchange.
The interchange between the previously disconnected faunas of North and South America was a massive experiment in biological invasion. A major gap in our understanding of this invasion is why there was a drastic increase in the proportion of mammals of North American origin found in South America. Four nonmutually... -

The rise of angiosperms pushed conifers to decline during global cooling
Competition among species and entire clades can impact species diversification and extinction, which can shape macroevolutionary patterns. The fossil record shows successive biotic turnovers such that a dominant group is replaced by another. One striking example involves the decline of gymnosperms and the rapid diversification and ecological dominance of angiosperms...Condamine, Fabien L. ; Silvestro, Daniele ; Koppelhus, Eva B. ; Antonelli, Alexandre

The past and future human impact on mammalian diversity
To understand the current biodiversity crisis, it is crucial to determine how humans have affected biodiversity in the past. However, the extent of human involvement in species extinctions from the Late Pleistocene onward remains contentious. Here, we apply Bayesian models to the fossil record to estimate how mammalian extinction rates...Andermann, Tobias ; Faurby, Søren ; Turvey, Samuel T. ; Antonelli, Alexandre ; Silvestro, Daniele

Selective extinction against redundant species buffers functional diversity
The extinction of species can destabilize ecological processes. A way to assess the ecological consequences of species loss is by examining changes in functional diversity. The preservation of functional diversity depends on the range of ecological roles performed by species, or functional richness, and the number of species per role,...Pimiento, Catalina ; Bacon, Christine D. ; Silvestro, Daniele ; Hendy, Austin ; Jaramillo, Carlos …
