Abstract Many cockroach species have adapted to urban environments, and some been serious pests of public health in the tropics subtropics. Here, we present 3.38-Gb genome a consensus gene set American cockroach, Periplaneta americana . We report insights from both genomic functional investigations into underlying basis its adaptation environments developmental plasticity. In comparison with other insects, expansions families P. exist for most core likely associated environmental adaptation,...
Cholesterol plays essential roles in animal development and disease progression. Here, we characterize the evolutionary pattern of canonical cholesterol biosynthesis pathway (CBP) kingdom using both genome-wide analyses functional experiments. CBP genes basal metazoans were inherited from their last common eukaryotic ancestor evolutionarily conserved for biosynthesis. The genomes deuterostomes retain almost full set genes, while Cnidaria many protostomes have independently experienced...
Abstract Until the advent of phylogenomics, atypical morphology extant representatives insect orders Grylloblattodea (ice‐crawlers) and Mantophasmatodea (gladiators) had confounding effects on efforts to resolve their placement within Polyneoptera. This recent research has unequivocally shown that these species‐poor groups are closely related form clade Xenonomia. Nonetheless, divergence dates remain poorly constrained, evolutionary history debated, as few well‐identified fossils,...
Food consumption, faecal production and nitrogen excretion by minnows, Phoxinus phoxinus , weighing 1–5.5 g were studied at five rations ranging from starvation to ad libitum four temperatures 5 15°C. The maximum rate of food consumption (C max ) was related body weight ( W temperature T the relationship: C = aW b1 b2 . There significant daily variations in which tended decline over time. Absorption efficiency increased with increasing ration size decreasing temperature. Body had no effect...
The effects of ration and temperature on the body composition, energy content indices condition minnow. Phoxinus phoxinus (L.) (Cyprinidae). were studied experimentally. Five levels over range starvation to ad libitum five temperatures 5–15°C used. fish weighed 1‐5‐4 g. At each temperature, relative dry matter content, lipid increased with ration. response protein was temperature‐dependent. Temperature had a significant effect composition but this irregular. Fulton factor less sensitive than...
Abstract Background Stem-relatives of many winged insect orders have been identified among Pennsylvanian fossils (Carboniferous Period). Owing to their presumed 'basal' position in phylogeny, stoneflies were expected occur at this period. However, no relative has ever designated convincingly. Results In paper, we report specimens belonging a new fossil species collected from the Tupo Formation (Pennsylvanian; China). The wing venation Gulou carpenteri gen. et sp. nov . exhibits character...
Background Fossil species that can be conclusively identified as stem-relatives of stick- and leaf-insects (Phasmatodea) are extremely rare, especially for the Mesozoic era. This dearth in paleontological record makes assessments on origin age group problematic impedes investigations evolutionary key aspects, such wing development, sexual size dimorphism plant mimicry. Methodology/Principal Findings A new fossil insect species, Cretophasmomima melanogramma Wang, Béthoux Ren sp. nov., is...
The fossil species Prochaeradodis enigmaticusPiton, 1940, from Menat (France, Paleocene) has been regarded as a crown-Mantodea (praying mantis) and was subsequently used one of the very few temporal calibration points relevant for order. Ambiguities in previous descriptions prompted us to re-examine type material. Based on our new observations broad comparative analysis across Dictyoptera, we recognized three independent morphological character states supporting an unequivocal placement...
Growth of minnows, Phoxinus phoxinus , weighing 1‐5.5 g was studied experimentally at five ration levels from starvation to ad libitum and four temperatures ranging 5 15°C. The relationship between specific growth rate (SGR) a decelerating curve. SGR maximum rations increased with temperature, but restricted it decreased temperature. Predictive models for the rates were developed using multiple regression. Maintenance optimum both less sensitive temperature than mostly lay 1 2% body weight...

Introduction Power industry is one of the largest sources CO 2 emissions in China. The Yellow River Basin plays a supportive role guaranteeing effective supply electricity nationwide, with numerous power generation bases. Understanding drivers and peak vital for China to fulfill its commitment reach carbon by 2030. Methods Logarithmic Mean Divisia Index (LMDI) model was employed explore change industries three study areas, including Inner Mongolia Autonomous Regions, Shanxi Province,...
The expansion of GGC repeats within NOTCH2NLC leads to translation the uN2CpolyG protein, primary pathogenic factor in neuronal intranuclear inclusion disease (NIID). aim this study was explore deposition as an amyloid vessel wall, leading cerebral angiopathy-related microbleeds (CMBs). A total 97 patients with genetically confirmed NIID were enrolled study. We analysed presence CMBs using susceptibility-weighted imaging sequences and compared general clinical information, cerebrovascular...
Grylloblattodea are one of the most unusual groups insects and second smallest order. All known extant species wingless exhibit a remarkable preference for cold temperatures. Although their morphology was intensively investigated shortly after discovery, systematic position has been disputed long time. The placement as sister-group to recently described Mantophasamtodea is supported by morphological molecular evidence. However, relationships this clade, Xenonomia, among polyneopteran...
Zygentoma occupies a key evolutionary position for understanding the evolution of insect metamorphosis but has received little attention in terms genetic analysis. To develop functional genomic studies this insect, we evaluated five candidate internal reference genes quantitative RT-PCR (qPCR) from Thermobia domestica, representative species Zygentoma, including Actin 5C (Actin5C), Elongation factor-1 alpha (EF1A), Ribosome protein S26 (RPS26), L32 (RPL32), and Superoxide dismutase 2 (SOD2),...
The family Sinonamuropteridae has been erected for nine fossil insect species from the Late Carboniferous Tupo Formation (Ningxia, China), each represented by a single isolated forewing. assigned to order Diaphanopterodea (extinct palaeopteran order). We investigated forewing venation pattern and its variability in this based on an abundant collection same locality. Based new data Chelopterum peregrinum Carpenter, 1950 (Grylloblattida; Lower Permian; Wellington Formation, U.S.A.) material,...
Insects have evolved numerous adaptations and colonized diverse terrestrial environments. Several polyneopterans, including dictyopterans (cockroaches mantids) locusts, developed oothecae, but little is known about the molecular mechanism, physiological function, evolutionary significance of ootheca formation. Here, we demonstrate that cockroach asymmetric colleterial glands produce vitellogenins, proline-rich protein, glycine-rich protein as major structural proteins (OSPs) undergo...
Abstract Protein degradation occurs during the processing of dry‐cured ham, which has important influences on flavor and quality products. The aim this work was to study kinetics myofibrillar proteins (MPs) sarcoplasmic (SPs) extracted from biceps femoris muscle Xuan'en ham. A relationship between protein formation found. During MPs SPs were mainly degraded in salting stage incipient fermentation. Accompanied by degradation, content carbonyl group increased gradually, but MPs, it first then...
