Speciation, dispersal and the build‐up of fern diversity in the American tropics Open
Understanding how the remarkable biodiversity of the American tropics developed has been a long‐standing question, yet knowledge gaps remain. Previous studies examined the roles of bioregions in shaping diversity patterns but often overloo…

A densely sampled nuclear phylogenomic analysis of the coryphoid palms (Arecaceae: Coryphoideae) Open
The palm family (Arecaceae) has a rich history of phylogenetic research, including several recent phylogenomic studies. However, densely sampled phylogenomic datasets for larger palm clades – such as subfamilies – are still few in number. …
The Arabidopsis thaliana core splicing factor PORCUPINE/SmE1 requires intron-mediated expression Open
Plants are prone to genome duplications and tend to preserve multiple gene copies. This is also the case for the genes encoding the Sm proteins of Arabidopsis thaliana (L). The Sm proteins are best known for their roles in RNA processing s…

Early Cretaceous Origin and Evolutionary History of Palms (Arecaceae) inferred from 1,033 Nuclear Genes and a New Synthesis of Fossil Evidence Open
Tropical rainforests are home to almost half of all known plant diversity, yet a shortfall in tropical plant phylogenetic hypotheses is hindering our understanding of how rainforests have formed and adapted to past global changes. Phylogen…

Genomic signatures of past megafrugivore‐mediated dispersal in Malagasy palms Open
Seed dispersal affects gene flow and hence genetic differentiation of plant populations. During the Late Quaternary, most fruit‐eating and seed‐dispersing megafauna went extinct, but whether these animals have left signatures in the popula…

Explaining extreme differences in species richness among co-occurring palm clades in Madagascar Open
Imbalance in species richness among related clades is a pervasive, yet incompletely understood feature of biodiversity. Comparison of species-poor and species-rich clades that have evolved within the same region can shed light on the mecha…
Occurrence-based diversity estimation reveals macroecological and conservation knowledge gaps for global woody plants Open
Incomplete sampling of species’ geographic distributions has challenged biogeographers for many years to precisely quantify global-scale biodiversity patterns. After correcting for the spatial inequality of sample completeness, we generate…

Truongsonia (Arecaceae: Arecoideae: Truongsonieae)—a new palm genus and tribe from Vietnam Open
A genus and species of palm from the Truong Son Range in Vietnam, Truongsonia lecongkietii, is described as new to science. Phylogenomic analysis strongly supports the placement of the new taxon in subfamily Arecoideae as sister to the Afr…
Global hotspots of plant phylogenetic diversity Open
Summary Regions harbouring high unique phylogenetic diversity (PD) are priority targets for conservation. Here, we analyse the global distribution of plant PD, which remains poorly understood despite plants being the foundation of most ter…
A species‐level phylogenetic framework and infrageneric classification for the genus<i>Maesa</i>(Primulaceae) Open
The systematization of Maesa , a genus of almost 200 species, has haunted taxonomists for more than a century due to its lack of distinct qualitative characters or discontinuities in quantitative characters for species delimitation. The cl…

Global shortfalls in threat assessments for endemic flora by country Open
Societal Impact Statement Plants are fundamental to terrestrial and aquatic ecosystems and are key to human livelihoods. To protect plant diversity, systematic approaches to conservation assessment are needed. Many nations have legislation…

Global beta-diversity of angiosperm trees is shaped by Quaternary climate change Open
As Earth’s climate has varied strongly through geological time, studying the impacts of past climate change on biodiversity helps to understand the risks from future climate change. However, it remains unclear how paleoclimate shapes spati…
Genomic signatures of past megafrugivore-mediated dispersal in Malagasy palms Open
Seed dispersal is a key process in the generation and maintenance of genetic diversity and genetic differentiation of plant populations in tropical ecosystems. During the Last Quaternary, most seed-dispersing megafauna was lost globally, b…

Socioeconomics and biogeography jointly drive geographic biases in our knowledge of plant traits: a global assessment of the Raunkiærian shortfall in plants Open
Summary The traits of plants determine how they interact with each other and their environment, constituting key knowledge for diverse fields. The lack of comprehensive knowledge of plant traits (the “Raunkiærian shortfall”) poses a major,…

Phylogenomics and generic limits of Dypsidinae (Arecaceae), the largest palm radiation in Madagascar Open
With 178 species, palm subtribe Dypsidinae is one of the largest plant radiations on Madagascar. A well‐resolved species‐level phylogeny is required not only to unpick the drivers of this spectacular radiation, but also to define natural a…
Global variation in diversification rate and species richness are unlinked in plants Open
Species richness varies immensely around the world. Variation in the rate of diversification (speciation minus extinction) is often hypothesized to explain this pattern, while alternative explanations invoke time or ecological carrying cap…

High exposure of global tree diversity to human pressure Open
Safeguarding Earth’s tree diversity is a conservation priority due to the importance of trees for biodiversity and ecosystem functions and services such as carbon sequestration. Here, we improve the foundation for effective conservation of…
The Darwinian shortfall in plants: phylogenetic knowledge is driven by range size Open
The Darwinian shortfall, i.e. the lack of knowledge of phylogenetic relationships, significantly impedes our understanding of evolutionary drivers of global patterns of biodiversity. Spatial bias in the Darwinian shortfall, where phylogene…
The Implications of Incongruence between Gene Tree and Species Tree Topologies for Divergence Time Estimation Open
Phylogenetic analyses are increasingly being performed with data sets that incorporate hundreds of loci. Due to incomplete lineage sorting, hybridization, and horizontal gene transfer, the gene trees for these loci may often have topologie…
Megafrugivores as fading shadows of the past: extant frugivores and the abiotic environment as the most important determinants of the distribution of palms in Madagascar Open
The extinction of all Madagascar's megafrugivores ca 1000 years ago, may have left its signature on the current distribution of vertebrate‐dispersed plants across the island, due to the loss of effective seed dispersal. In this study, we d…
Palm functional trait responses to local environmental factors in the Colombian Amazon Open
Functional traits play a key role in driving plant community effects on ecosystem function. We examined nine functional traits in various palm (Arecaceae) species and their relationships with moisture, tree-fall gaps, slope, and forest typ…
