The evolutionary history of the Central Asian steppe-desert taxon Nitraria (Nitrariaceae) as revealed by integration of fossil pollen morphology and molecular data.
The transition from a greenhouse to an icehouse world at the Eocene-Oligocene Transition (EOT) coincided with a large decrease of pollen from the steppe-adapted genus Nitraria. This genus, now common along the Mediterranean coast, Asia and Australia, has a proposed coastal origin and a geographically widespread fossil record. Here we... -

The origin of modern patterns of continental diversity in Mauritiinae palms: the Neotropical museum and the Afrotropical graveyard.
While the latitudinal diversity gradient has received much attention, biodiversity and species richness also vary between continents across similar latitudes. Fossil information can be used to understand the evolutionary mechanisms that generated such variation between continents of similar latitudes. We integrated fossil data into a phylogenetic analysis of the Mauritiinae... -

Fossil data support a pre-Cretaceous origin of flowering plants
Flowering plants (angiosperms) are the most diverse of all land plants, becoming abundant in the Cretaceous and achieving dominance in the Cenozoic. However, the exact timing of their origin remains a controversial topic, with molecular clocks generally placing their origin much further back in time than the oldest unequivocal fossils....Silvestro, Daniele ; Bacon, Christine D. ; Ding, Wenna ; Zhang, Qiuyue ; Donoghue, Philip C.

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 …

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

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
