We present a molecular assessment of the widely-distributed ricefrog(Fejervarya limnocharis)which provides many newsamples that add to knowledge of their phylogeography within China and considersgenetic support forfive Chinese species withinthis complex.TwomtDNAfragments from 270 individuals and eight nuclearDNAloci(105 individuals)were sequenced from specimens sampled from across China.Data from nine specimens from China,Indonesia and Japan were also retrieved from previous studies.MtDNAwas informativeabout population divergence within China and indicated one major clade(with four subclades)from South China and the Zhoushan Archipelago,Zhejiang,China,and a second major clade(with eight subclades)from other parts of China.Recent demographic expansions(less than 50ka ago)were detected within three of these 12 subclades,potentially associa ted with lowered sea-levels after marine transgressions.Nota bly,most frogs from the previously unstudied Zhoushan Archipelago(eastern China)were found to be closely related to Japanese populations.BPPand STACEY species delimitation analyses of the multilocus data favoured five candidate species within the complex.Previous work had described Fejervaryamultistriata and F.kawamurai from the Chinese mainland although here we detected considerable genetic divergence within the latter and found that this may be indicative of two species.One of these corresponds to the Zhoushan Archipelago,Zhejiang,China and Japan,and the other from most parts of Chinese mainland.This study provides a large multilocus dataset that contributes to the systematics of this species complex.

The Impact of Phenotypic Characteristics on Thermoregulation in a Cold-Climate Agamid lizard,Phrynocephalus guinanensis

引用

Asian Herpetological Research 2016年第3期7卷 210-219页

作者： Yuanting JIN haojie tong Kailong ZHANG College of Life Sciences China Jiliang University

Physiological and metabolic processes of ectotherms are markedly influenced by ambient temperature. Previous studies have shown that the abdominal black-speckled area becomes larger with increased elevation in plateau Phrynocephalus, however, no studies have verified the hypothesis that this variation is correlated with the lizard＇s thermoregulation. In this study, infrared thermal imaging technology was first used to study the skin temperature variation of torsos, heads, limbs and tails of a cold-climate agamid lizard, Phrynocephalus guinanensis. The heating rates of the central abdominal black-speckled skin area and peripheral non-black-speckled skin area under solar radiation were compared. Our results showed that the heating rates of limbs and tails were relatively faster than the torsos, as heating time was extended, rates gradually slowed before stabilizing under solar radiation. Under the environment without solar radiation, the cooling rates of limbs and tails were also relatively faster than the torsos of lizards, the rates slowed down and finally became stable as the cooling time was extended. We also found that the heating rate of the abdominal black-speckled skin area was faster than the nearby non-black-speckled skin area. These results increased our insights into the functional significance of these phenotypic traits and help explain their covariation with the thermal environment in these cold-climate agamid lizards.

Phylogenetic,Demographic and Dating Analyses of Bufo gargarizans Populations from the Zhoushan Archipelago and China's Mainland

引用

Asian Herpetological Research 2017年第3期18卷 165-173页

作者： haojie tong Yubin WO Pinghu LIAO Yuanting JIN College of Life Sciences China Jiliang University

Relatively little is known about the relationship between Bufo gargarizans populations from Zhoushan Archipelago and nearby continental regions on the Pacific coast of eastern China.In this paper,155 new specimens of B.gargarizans from Zhoushan Archipelago and adjacent continents and 71 published specimens of B.gargarizans from China's Mainland were studied.Phylogeographical and dating analyses of B.gargarizans were performed using mitochondrial DNA sequencing with a length of 1436 bp.A mt DNA tree that indicated seven major clades was obtained.The earliest split in the mt DNA tree corresponding to the divergence of populations from the western highland region occurred approximately 4.0 million years ago（mya）.A subsequent clade occurred about 3.4 mya,with cladogenesis continuing toward the end of the Pleistocene.The continental clades were distributed in the western,central and northeastern regions of China.Zhoushan Archipelago clades consisted of two largely geographically overlapping subclades with the mt DNA divergence time of 0.73 mya.These results indicated there was extensive dispersal after vicariance.The B.gargarizans populations on Zhoushan Archipelago most probably originated from populations in nearby eastern continental regions of China.It was concluded that geological uplifting during the Pliocene and several sea-level changes in Pleistocene might have influenced the divergence and population demographical history of this species.

Sex Ratio and Sexual Size Dimorphism in a Toad-headed Lizard, Phrynocephalus guinanensis

Asian Herpetological Research 2018年第1期9卷 35-42页

作者： Kailong ZHANG haojie tong Yubin WO Naifa LIU Yuanting JIN College of Life Sciences China Jiliang University School of Life Sciences Lanzhou University

Phrynocephalus guinanensis has sexual dimorphism in abdominal coloration, but its ontogenetic development of sexual size dimorphism （SSD） is unknown. Using mark-recapture data during four days each year from August from 2014 to 2016, we investigated the development of sex ratios, SSD, sex-specific survivorship and growth rates in a population of P guinanensis. Our results indicated that the sex ratio of males to females was 1：2.8. Males had a lower survival rate （6%） than females （14%） across the age range from hatchling to adult, which supported the discovered female-biased sex ratio potentially associated with the low survival rate of males between hatchlings and juveniles. Male-biased SSD in tail length and head width existed in adults rather than in hatchling or juvenile lizards. The growth rates in body dimensions were undistinguishable between the sexes during the age from hatchling to juvenile, but the growth rate in head length from juvenile to adult was significantly larger in males than females. Average growth rate of all morphological measurements from hatchling to juvenile were larger compared with corresponding measurements from juvenile to adult, but only being significant in tail length, head width, abdomen length in females and snout-vent length in males. We provided a case study to strengthen our understanding of the important life history traits on how a viviparous lizard population can survive and develop their morphology in cold climates.

Elevation as a selective force on mitochondrial respiratory chain complexes of the Phrynocephalus lizards in the Tibetan plateau

Current Zoology 2021年第2期67卷 191-199页

Animals living in extremely high elevations have to adapt to low temperatures and low oxygen availability(hypoxia),but the underlying genetic mechanisms associated with these adaptations are still unclear.The mitochondrial respiratory chain can provide>95%of the ATP in animal cells,and its efficiency is influenced by temperature and oxygen availability.Therefore,the respiratory chain complexes(RCCs)could be important molecular targets for positive selection associated with respiratory adaptation in high-altitude environments.Here,we investigated positive selection in 5 RCCs and their assembly factors by analyzing sequences of 106 genes obtained through RNA-seq of all 15 Chinese Phrynocephalus lizard species,which are distributed from lowlands to the Tibetan plateau(average elevation>4,500 m).Our results indicate that evidence of positive selec-tion on RCC genes is not significantly different from assembly factors,and we found no difference in selective pressures among the 5 complexes.We specifically looked for positive selection in line-ages where changes in habitat elevation happened.The group of lineages evolving from low to high altitude show stronger signals of positive selection than lineages evolving from high to low elevations.Lineages evolving from low to high elevation also have more shared codons under positive selection,though the changes are not equivalent at the amino acid level.This study advan-ces our understanding of the genetic basis of animal respiratory metabolism evolution in extreme high environments and provides candidate genes for further confirmation with functional analyses.

Exercise-with-melatonin therapy improves sleep disorder and motor dysfunction in a rat model of ischemic stroke

Neural Regeneration Research 2024年第6期19卷 1336-1343页

Exercise-with-melatonin therapy has complementary and synergistic effects on spinal cord injury and Alzheimer’s disease, but its effect on stroke is still poorly understood. In this study, we established a rat model of ischemic stroke by occluding the middle cerebral artery for 60 minutes. We treated the rats with exercise and melatonin therapy for 7 consecutive days. Results showed that exercise-with-melatonin therapy significantly prolonged sleep duration in the model rats, increased delta power values, and regularized delta power rhythm. Additionally, exercise-with-melatonin therapy improved coordination, endurance, and grip strength, as well as learning and memory abilities. At the same time, it led to higher hippocampal CA1 neuron activity and postsynaptic density thickness and lower expression of glutamate receptor 2 than did exercise or melatonin therapy alone. These findings suggest that exercise-withmelatonin therapy can alleviate sleep disorder and motor dysfunction by increasing glutamate receptor 2 protein expression and regulating hippocampal CA1 synaptic plasticity.

In order to improve the properties of titanium alloys manufactured by laser melting deposition(LMD),the electroshocking treatment(EST)was proposed in this work.The effects of EST on microstructure and mechanical properties of LMD Ti-6.5Al-3.5Mo-1.5Zr-0.3Si were investigated.The results showed that the width of the heat affected band decreased and disappeared under the thermal and athermal effects of EST,resulting in the uniform microstructure.In the microstructure,theαlaths became coarser gradually,and the quantity ofα/βinterface was reduced.The reduction of the quantity ofα/βinterface leads to make less resistant to dislocation,resulting in the reduction in hardness and strength.The discontinuous grain boundaryαphase and nucleationαcolony near grain boundary inhibited the crack propagation and improved the ductility.Summary,EST can manipulate the microstructure and improve the mechanical properties of LMD titanium alloys.
