Madagascar’s extraordinary biodiversity: Threats and opportunities.
Madagascar’s unique biota is heavily affected by human activity and is under intense threat. Here, we review the current state of knowledge on the conservation status of Madagascar’s terrestrial and freshwater biodiversity by presenting data and analyses on documented and predicted species-level conservation statuses, the most prevalent and relevant threats,... -

Madagascar’s extraordinary biodiversity: Evolution, distribution, and use.
Madagascar’s biota is hyperdiverse and includes exceptional levels of endemicity. We review the current state of knowledge on Madagascar’s past and current terrestrial and freshwater biodiversity by compiling and presenting comprehensive data on species diversity, endemism, and rates of species description and human uses, in addition to presenting an updated... -

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... -

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

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 …

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 …
