The royal ferns (Osmundales) are a morphologically diverse group of leptosporangiate ferns, the fossil record of which dates back to the Permian. Despite there being numerous described permineralized species, the phylogenetic relationships ...

Each published phylogeny is a potential contribution to the synthesis of the Tree of Life and countless downstream projects. Steps are needed for fully synthesizable science, but only a minority of studies achieve these. We here review the ...
Body size and evolutionary rate analyses reveal complex evolutionary history of Alvarezsauria [0.03%]
体型和进化速率分析揭示了 Alvarezsauria 复杂的进化历史

Jorge Gustavo Meso et al.
Some of the smallest examples of dinosaurian body size are from alvarezsaurians, an enigmatic group of maniraptoran coelurosaurians with a peculiar combination of anatomical features unique among theropods. Despite the large number of alvar...
Incomplete barriers to heterospecific mating among Somatochlora species (Odonata: Corduliidae) as revealed in multi-gene phylogenies [0.03%]
基于多基因系统发育的同翅目巨翅科尺蜻蛉属间物种杂交不完全障碍的研究

Mating between species occurs within many insect orders. The result of heterospecific mating depends upon the effectiveness of pre- and post-reproductive barriers. Incomplete reproductive barriers lead to introgression of DNA into one speci...
Rethinking spatial history: envisioning a mechanistic historical biogeography [0.03%]

Historical biogeography is the study of geographic distributions of taxa through space and time. Over the last 50 years, several methods have been proposed to reconstruct these histories. However, despite their particularities, conceptually...
Robust phylogenomics settles controversies of classification and reveals evolution of male embolic complex of the Laufeia clade (Araneae, Salticidae, Euophryini) [0.03%]
稳健的衍征基因组学解决了分类争议并揭示了Laufeia类群(Araneae,Salticidae,Euophryini)中雄性附器复合体的进化历程
Kun Yu,Feng Zhang,Yaozhuo Wang et al.
Kun Yu et al.
The Laufeia clade is a peculiar lineage of euophryine jumping spiders showing rapid divergence of male genital structures, especially the embolic complex that directly interacts with female genitalia during sperm transfer. With the rapid gr...
Plant species diversification in the Himalaya-Hengduan Mountains region: an example from an endemic lineage of Pedicularis (Orobanchaceae) in the role of floral specializations and rapid range expansions [0.03%]
横断山-喜马拉雅山脉地区植物多样化以列当科红苞雪兔子特有谱系为例探讨花部特化及快速扩散的作用

Rong Liu et al.
The c. 270 endemic species of Pedicularis in the Himalaya-Hengduan Mountains (HHM) region exhibit high diversity in geographic distribution, elevational range and floral morphology. Many of these, including the species with the longest coro...
A targeted gene phylogenetic framework to investigate diversification in the highly diverse yet geographically restricted red devil spiders (Araneae, Dysderidae) [0.03%]

The family Dysderidae is a highly diverse group of nocturnal ground-dwelling and active-hunter spiders. Dysderids are mostly restricted to the Western Palearctic, and particularly rich and abundant around the Mediterranean region. Interesti...
Insights from the first phylogenomic analysis of flat wasps (Hymenoptera, Bethylidae) reveal two new subfamilies [0.03%]
