Connecting the multiple dimensions of global soil fungal diversity.
How the multiple facets of soil fungal diversity vary worldwide remains virtually unknown, hindering the management of this essential species-rich group. By sequencing high-resolution DNA markers in over 4000 topsoil samples from natural and human-altered ecosystems across all continents, we illustrate the distributions and drivers of different levels of taxonomic... -

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

No one-size-fits-all solution to clean GBIF.
Species occurrence records provide the basis for many biodiversity studies. They derive from georeferenced specimens deposited in natural history collections and visual observations, such as those obtained through various mobile applications. Given the rapid increase in availability of such data, the control of quality and accuracy constitutes a particular concern.... -

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 …

Unraveling the Phylogenomic Relationships of the Most Diverse African Palm Genus Raphia (Calamoideae, Arecaceae)
Palms are conspicuous floristic elements across the tropics. In continental Africa, even though there are less than 70 documented species, they are omnipresent across the tropical landscape. The genus Raphia has 20 accepted species in Africa and one species endemic to the Neotropics. It is the most economically important genus...Helmstetter, Andrew J. ; Kamga, Suzanne Mogue ; Bethune, Kevin ; Lautenschläger, Thea ; Zizka, Alexander …
