Here, we provide a de novo genome hot-spring snake, baileyi , conduct series comparisons with other reptiles. We identify genes under positive selection test properties allelic variants proteins that involved DNA damage repair responses hypoxia. Functional assays reveal convergent...
Snakes are a remarkable squamate lineage with unique morphological adaptations, especially those related to the evolution of vertebrate skeletons, organs, and sensory systems. To clarify genetic underpinnings snake phenotypes, we assembled analyzed 14 de novo genomes from 12 families. We also investigated basis characteristics snakes using functional experiments. identified genes, regulatory elements, structural variations that have potentially contributed limb loss, an elongated body plan,...
Identifying and protecting hotspots of endemism species richness is crucial for mitigating the global biodiversity crisis. However, our understanding spatial diversity patterns far from complete, which severely limits ability to conserve hotspots. Here, we report a comprehensive analysis amphibian in China, one most species-rich countries on Earth. Our study combines 20 y field surveys with new molecular analyses 521 described also identifies 100 potential cryptic species. We identify 10...
A new species of the genus Dendrelaphis is described from Xishuangbanna, southern Yunnan, China, based on molecular and morphological data. The can be differentiated other congeners by following combination characters: 1) ground color body bronze, a black postocular stripe extending onto neck only; 2) pale dark ventrolateral absent; 3) relatively indistinct transverse bands anterior part lateral body; 4) loreal single; 5) vertebral scales strongly enlarged; 6) dorsal scale rows 15-15-11, all...
The exchange of biotas between Eurasia and North America across the Bering land bridge had a major impact on ecosystems both continents throughout Cenozoic. This has received particular attention regarding placental mammals dispersing into Americas, including humans after last glacial period, also as an explanation for disjunct distribution related seed plants in eastern Asia America. Here, we investigate bi-directional dispersal from estimates events based time-calibrated phylogenies broad...

DNA barcoding has greatly facilitated studies of taxonomy, biodiversity, biological conservation, and ecology. Here, we establish a reliable library for Chinese snakes, unveiling hidden diversity with implications provide standardized tool conservation management. Our comprehensive study includes 1638 cytochrome c oxidase subunit I (COI) sequences from snakes that correspond to 17 families, 65 genera, 228 named species (80.6% species) 36 candidate species. A barcode gap analysis reveals...
The transition of terrestrial snakes to marine life ∼10 Ma is ideal for exploring adaptive evolution. Sea possess phenotype specializations including laterally compressed bodies, paddle-shaped tails, valvular nostrils, cutaneous respiration, elongated lungs, and salt glands, yet, knowledge on the genetic underpinnings remains limited. Herein, we report first genome Shaw's sea snake (Hydrophis curtus) use it investigate secondary adaptation. A hybrid assembly strategy obtains a high-quality...
The genus Scincella Mittleman, 1950, belonging to the family Scincidae, exhibits considerable morphological convergence, complicating species delimitation and resulting in underestimated diversity. Currently, 41 are formally recognized this genus, although figure likely underestimates its true richness. In study, a new of Scincella, chengduensis sp. nov., is described from urban suburban areas Chengdu, Sichuan Province, Southwest China. Morphological features phylogenetic analyses confirmed...
The flowerpot snake ( Indotyphlops braminus ) is the only known parthenogenetic and triploid species within Serpentes. However, genetic basis underlying this phenomenon remains unresolved. We investigated genomic complexities of rare all-female reptile. On newly assembled genome, we revealed 40 chromosomes grouped into three subgenomes (A, B, C). Comparative analysis with related diploid a chromosome fusion event in ancestral genomes. This shaped unique landscape snake. examined gene...
The Oriental garden lizard (Calotes versicolor) is one of the few non-gekkonid lizards that are geographically widespread in tropics. We investigated its population dynamics on Hainan Island and adjacent mainland China Vietnam, focusing impact cyclic upheaval submergence land bridges during Pleistocene. Our Bayesian phylogenetic analysis reveals two mitochondrial lineages, A B, which estimated to have coalesced about 0.26 million years ago (95% credibility interval: 0.05–0.61 ago). Lineage...
Abstract The Tibetan Plateau (TP) and surrounding regions have one of the most complex biotas on Earth. However, evolutionary history these in deep time is poorly understood. Here, we quantify temporal changes beta dissimilarities among zoogeographical during Cenozoic using 4,966 extant terrestrial vertebrates 1,278 extinct mammal genera. We identify ten present-day find that they underwent a striking change over time. Specifically, fauna TP was close to Oriental realm but became more...
Bungarus multicinctus is a widely distributed and medically important elapid snake that produces lethal neurotoxic venom. To study enhance existing antivenom, we explore the complete repertoire of its toxin genes based on de novo chromosome-level assembly multi-tissue transcriptome data. Comparative genomic analyses suggest three-finger family (3FTX) may evolve through neofunctionalization flanking LY6E. A long-neglected 3FTX subfamily (i.e., MKA-3FTX) also investigated. Only one MKA-3FTX...
Abstract Over the past 40 years, climate has been changing and human disturbance increased in vast Qinghai–Tibet Plateau (QTP). These 2 factors are expected to affect distribution of a large number endemic vertebrate species. However, quantitative relationships between range shifts change these species QTP have rarely evaluated. We used occurrence records 19 terrestrial (birds, mammals, amphibians, reptiles) occurring from 1980 2020 quantify effects anthropogenic impacts on 4 taxonomic...
Abstract Background Reptiles exhibit a wide variety of skin colors, which serve essential roles in survival and reproduction. However, the molecular basis these conspicuous colors remains unresolved. Results We investigate color morph-enriched Asian vine snakes ( Ahaetulla prasina ), to explore mechanism underpinning variations.

Abstract Gut microbiota are significant to the host’s nutrition and provide a flexible way for host adapt extreme environments. However, whether gut help colonize caves, resource-limited environment, remains unknown. The nonobligate cave frog Oreolalax rhodostigmatus completes its metamorphosis within caves 3–5 years before foraging outside. Their tadpoles occasionally removed from by floods utilize outside resources, providing contrast cave-dwelling population. For both tadpoles,...
Abstract The Himalaya presents an outstanding geologically active orogen and biodiversity hotspot. However, our understanding of the historical biogeography its fauna is far from comprehensive. Many taxa are commonly assumed to have originated China-Indochina dispersed westward along Himalayan chain. Alternatively, “Tibetan-origin hypothesis” suggests primary diversification lineages in Paleo-Tibet, secondary slopes later uplifted Greater Himalaya. We test these hypotheses high-mountain...
