Dinosaur fossils possessing integumentary appendages of various morphologies, interpreted as feathers, have greatly enhanced our understanding the evolutionary link between birds and dinosaurs, well origins feathers avian flight. In extant birds, unique expression amino acid composition proteins in mature been shown to determine their biomechanical properties, such hardness, resilience, plasticity. Here, we provide molecular ultrastructural evidence that pennaceous Jurassic nonavian dinosaur...
A combination of sectioning and microscopy techniques, along with the application finite-difference-time-domain modeling on a fossil feather, novelly results in estimation range iridescent colors from fossilized melanosomes preserved elongate head crest feathers new Cretaceous enantiornithine bird. The densely packed rod-like yield are estimated to have yielded red deep blue coloration feathers. shape density these melanosome may also further increased feather’s structural strength. This...

Abstract The hindlimb of theropod dinosaurs changed appreciably in the lineage leading to extant birds, becoming more ‘crouched’ association with changes body shape and gait dynamics. This postural evolution included anatomical foot ankle, altering moment arms control muscles that manipulated tarsometatarsus digits, but timing these is unknown. Here, we report cellular-level preservation tendon- cartilage-like tissues from lower Early Cretaceous Confuciusornis . digital flexor tendons passed...
China has experienced rapid urbanization since 1978, and the dramatic change in land cover is expected to have significant impacts on climate change. Some models been used simulate relationship between use change; however, there still no sufficient evidence for of regional climate. This study aims identify impact urban temperature precipitation summer Beijing-Tianjin-Tangshan Metropolitan area during 2030–2040 based analysis simulation results WRF model. Firstly, we analyzed 1995–2005 area....
We consider the solution of linear systems arising from porous media flow simulations with high heterogeneities. Using a Newton algorithm to handle nonlinearity leads solving sequence different but similar matrices and right-hand sides. The parallel solver is Schwarz domain decomposition method. unknowns are partitioned criterion based on entries input matrix. This substantial gains compared partition only adjacency graph From information generated during first system, it possible build...
SignificanceOwls, with their largely nocturnal habits, contrast strikingly the vast majority of diurnal birds. A new spectacular late Miocene owl skeleton from China unexpectedly preserves oldest evidence for daytime behavior in owls. The extinct is a member clade Surniini, which contains most living species. Analysis preserved eye bones documents them as consistent birds, and phylogenetically constrained character mapping coincides reconstruction an early evolutionary reversal away habits...
Late embryogenesis abundant (LEA) proteins are thought to protect against water stress in plants. Characteristics of sequence and expression barley gene HVA1, a member LEA group 3 protein, were investigated hulless (Hordeum vulgare ssp. vulgare), associated with phenotypically diverse drought-tolerant genotypes. Sensitive tolerant genotypes identified from Tibetan populations cultivated barley, based on scores loss rate (WLR), maldondialdehyde (MDA), proline content. The results indicated...
Land use/cover change (LUCC) is an important part of the global environmental change. This study predicted future structure land on basis Global Change Assessment Model (GCAM) and econometric model with socioeconomic factors as driving forces. The spatial pattern in China was simulated Dynamics System (DLS) under Business Usual scenario, Rapid Economic Growth scenario Cooperate Environmental Sustainability scenario. simulation results showed that use/land cover will continually due to human...
Abstract The remains of ovarian follicles reported in nine specimens basal birds represents one the most remarkable examples soft-tissue preservation Early Cretaceous Jehol Biota. This discovery was immediately contested and structures alternatively interpreted as ingested seeds. Fragments purported preserved an enantiornithine (STM10-12) were extracted subjected to multiple high-resolution analyses. STM10-12 possess histological histochemical characteristics smooth muscles fibers...
Abstract The low‐dimensional organic‐inorganic lead halide compound has garnered significant attention in recent times due to its exceptional optoelectronic properties. However, application the field of optoelectronics been hindered by toxicity lead. Here, a novel inorganic‐organic [Epy] 2 [CuBr 3 ] single crystal material with 0D structure based on Cu(I) is introduced. exhibits broad band yellow luminescence, Stokes shift, and microsecond‐scale photoluminescence (PL) lifetime, which mainly...
The interplay between the pectoral module (the girdle and limbs) pelvic plays a key role in shaping avian evolution, but prior empirical studies on trait covariation two modules are limited. Here we empirically test whether (size-corrected) sternal keel length ilium correlated during evolution using phylogenetic comparative methods. Our analyses extant birds Mesozoic both recover significantly positive correlation. results provide new evidence regarding integration modules. of may serve as...
ABSTRACT Exceptionally preserved fossil feathers and feather-like integumentary structures provide valuable insights into the early evolution of flight, but taphonomic biases often make interpretations at microstructural ultrastructural levels ambiguous. Maturation experiments have been demonstrated to be useful for investigating alterations soft tissues, including feathers, during diagenesis. However, experimentally matured resembling preserving keratinous matrix not yet obtained. Here we...
