The timing of the Jiufotang Formation remains speculative despite recent progress in study Jehol Biota. In this paper we contribute to topic with 40 Ar/ 39 Ar dating on K‐feldspar (sanidine and orthoclase) from tuffs interbedded within fossil‐bearing shales Formation, upper part Group Chaoyang, Liaoning, northeastern China. step heating analyses SHRIMP U‐Pb zircon data indicate that at Shangheshou section erupted 120.3 ± 0.7 million years ago. This result confirms an Aptian age for was...
Abstract The East Asian flora (EAF) is a key biodiversity hotspot for understanding the origin and evolution of Northern Hemisphere floras, but there an ongoing debate on whether it museum or cradle seed plants. Within EAF, two main Sino-Himalayan Flora (mainly Rhododendron Flora) Sino-Japanese Metasequoia Flora), have been recognized. Previous studies suggested that EAF ancient older than Flora. To test this hypothesis, we synthesized molecular as well fossil data plants, focusing...
The Hengduan Mountains (HDM) biodiversity hotspot exhibits exceptional alpine plant diversity. Here, we investigate factors driving intraspecific divergence within a HDM species Salix brachista (Cushion willow), common component of subnival assemblages. We produce high-quality genome assembly for this and characterize its genetic diversity, population structure pattern evolution by resequencing individuals collected across distribution. detect that has been shaped landscape isolated sky...
The 40 Ar/ 39 Ar step heating analyses of K‐feldspar derived from the ignimbrite in Inner Mongolia, China indicates that they were formed at 159.8 ± 0.8 Ma, which provides a maximum age for overlying fossil‐bearing lacustrine deposits (Daohugou Bed). This result favors post‐Middle Jurassic (Late or younger), rather than Middle Daohugou Bed. Such is generally consistent with vertebrate biostratigraphic evidence, providing known first appearance several major animal groups such as...
The bird fossil‐bearing deposits at the Jiecaigou section, correlative to Dabeigou Formation, in Fengning, Hebei Province, northern China, is well known for yielding a fossil assemblage representing earliest evolutionary stage of Jehol Biota. precise age deposits, however, unknown. 40 Ar/ 39 Ar spectrum obtained on bulk K‐feldspars from tuff layer about 2 m below gave plateau 129.0 ± 1.3 Ma (2σ, full external error) and an isochron 132.3 4.5 error). Seventeen total‐fusion ages interbedded 6...
The Lujiatun bed of the Yixian Formation is famous for its extraordinary preservation three‐dimensional fossils and implication most dramatic catastrophic mass mortality event in Jehol Biota. precise age fossil bearing deposits, however, remains to be established. 40 Ar/ 39 Ar step heating analyses on bulk K‐feldspars from tuff gave a weighted mean 123.2 ± 1.0 Ma (2σ). This date suggests was likely deposited at about same time as Jianshangou lower Formation, representing stage when dinosaurs...
Abstract Questions What is the community‐level consequence of biotic processes, in particular importance facilitation, determining patterns diversity alpine plant communities Himalayan Hengduan Mountains? Does facilitation intensity change with environmental severity, and are these changes due to severity or nurse trait effects? Location Eleven dominated by cushion plants Mountains, within mountain system south‐central China. Methods We determined species richness abundance habitats created...
The generic position of an aerobic, Gram-positive, non-acid-alcohol-fast actinomycete was determined following isolation the PCR-amplified 16S rRNA genes and alignment resultant sequence with corresponding sequences from representatives family Pseudonocardiaceae. assignment organism to genus Saccharopolyspora strongly supported by chemotaxonomic morphological data. strain distinguished validly described species a number phenotypic properties. It is proposed that organism, AS4.198T, be...
Abstract Deteriorating relations between the USA and China since 2018 have extended to education scientific research arenas. We put US–China science in a historical perspective describe win–win situation when both countries collaborated. discuss an ongoing loss–loss scenario of decoupling speculate its far-reaching adverse impacts beyond bilateral territories. call for actions be taken brighter future by leaderships countries.
The taxonomy of Euphorbiaceae is extremely difficult, especially the phylogeny closely related genera. In Ricinus, which embraces an important non-food oil-seed crop worldwide, Discocleidion and Speranskia are genera based on molecular evidence (tribe Ricineae), however intergeneric interspecific relationship tribe not well-resolved. Plastome transcriptome were sequenced assembled before maximum likelihood Bayesian inference phylogenetic trees reconstructed. features comparative analyses...
<h3>Background</h3> Anti-angiotensin II receptor subtype 1 (AT1 receptor) autoantibodies have previously been shown in sera of hypertensive patients. This study assessed whether anti-AT1-receptor autoantibody serum is correlated with the efficacy an AT1-receptor blocker (ARB; candesartan)-based regimen patients after 8 weeks treatment. <h3>Design</h3> The Study Optimal Treatment Hypertensive Patients Anti-AT1-Receptor Autoantibodies a multicentre, randomised, blinded endpoint, open-label,...
We describe for the first time histology of an ornithuromorph bird from Lower Cretaceous Jehol Group, revealing bone structure one oldest members this derived clade.The newly discovered Sihedang locality Yixian Formation in northeastern China preserves dominated avifauna, with all collected birds referable to a single taxon, Iteravis huchzermeyeri.These specimens are preserved relatively greater degree three-dimensionality compared other localities.We sampled specimen order test hypothesis...
Abstract It has been suggested that many plants now found in the arctic originated from ancestors occurred at high altitudes southern mountains of Northern Hemisphere during Tertiary. However, this hypothesis rarely tested using a molecular phylogenetic approach. Here, we present fossil‐calibrated phylogeny Lagotis , an arctic‐alpine genus with greatest diversity Qinghai‐Tibetan Plateau (QTP) and Central Asian mountains, based on five chloroplast ( matK psbA‐trnH rps16 trnG‐S trnL‐F )...
