Abstract Under long-standing threat of seasonal influenza outbreaks, it remains imperative to understand the drivers dynamics which can guide mitigation measures. While role absolute humidity and temperature is extensively studied, possibility ambient ozone (O 3 ) as an environmental driver has received scant attention. Here, using state-level data in USA during 2010–2015, we examined such research hypothesis. For rigorous causal inference by evidence triangulation, applied distinct methods...

Polyploids are organisms whose genomes consist of more than two complete sets chromosomes. Both autopolyploids and allopolyploids may display polysomic inheritance. A peculiarity inheritance is multivalent formation during meiosis resulting in double-reduction, which occurs when sister chromatid fragments segregate into the same gamete. Double-reduction can result gametes carrying identical-by-descent alleles slightly increasing homozygosity. This will cause genotypic frequencies to deviate...

Maintaining variation in immune genes, such as those of the major histocompatibility complex (MHC), is important for individuals small, isolated populations to resist pathogens and parasites. The golden snub-nosed monkey (Rhinopithecus roxellana), an endangered primate endemic China, has experienced a rapid reduction numbers severe population fragmentation over recent years. For this study, we measured DRB diversity among 122 monkeys from three Qinling Mountains, estimated relative...

Abstract Depicting a taxonomic group's evolutionary trajectory as function of changes in the geographical landscape and its historical distribution is critical for constructing informed conservation strategies. Based on fossil sites from Pliocene to Holocene, records since 1175 AD, we established macaques’ dispersal pathways into through China. These routes include internal starting southeast corner Qinghai‐Tibet Plateau Mts. Hengduan western China, estuaries three major rivers (Yangtze,...

According to a biological market paradigm, trading decisions between partners will be influenced by the current 'exchange rate' of commodities (good and services), which is affected supply demand, trader's ability outbid competitors. In several species nonhuman primates, newborn infants are attractive female group members may become desired commodity that can traded for grooming within place. We investigated whether was interchanged infant handling in golden snub-nosed monkeys (Rhinopithecus...

Abstract Duplicated loci, for example those associated with major histocompatibility complex (MHC) genes, often have similar DNA sequences that can be coamplified a pair of primers. This results in genotyping difficulties and inaccurate analyses. Here, we present method to assign alleles different loci amplifications duplicated loci. simultaneously considers several factors may each affect correct allele assignment. These are the sharing identical among null alleles, copy number variation,...

Abstract The analysis of molecular variance (AMOVA) is a widely used statistical method in population genetics and ecology. classic framework AMOVA only supports haploid diploid data, which the number hierarchies ranges from two to four. In practice, natural populations can be classified into more hierarchies, polyploidy frequently observed extant species. ploidy level may even vary within same species, and/or individual. We generalized such that it for any ploidy. Based on this framework,...

Genes of the major histocompatibility complex (MHC) play important roles in vertebrate immunocompetence. MHC genes thus offer females indirect benefits to mate choice through production offspring an optimal genotype. Females may choose males with specific haplotypes, dissimilar genotypes, heterozygous or MHC-diverse males. We tested these four alternatives for both female social and paternal wild golden snub-nosed monkeys (Rhinopithecus roxellana) by examining overall genetic variability...

The genes of the major histocompatibility complex (MHC) are an important component vertebrate immune system and play a significant role in mate choice many species. However, it remains unclear whether female non-human primates is based on specific functional and/or genome-wide genes. golden snub-nosed monkey ( Rhinopithecus roxellana ) lives multilevel society, which consists several polygynous one-male-several-female units. Although adult females tend to mainly socialize with one male,...

Abstract A significant portion of plant species are polyploids, with ploidy levels sometimes varying among individuals and/or populations. Current techniques to determine the individual ploidy, e.g., flow cytometry, chromosome counting or genotyping‐by‐sequencing, often cumbersome. Based on genotypic probabilities for polysomic inheritance under double‐reduction, we developed a model estimate allele frequency and infer status from allelic phenotypes codominant genetic markers. The...

Genetic diversity is an essential indicator that echoes the natural selection and environmental adaptation of a species. Isolated small populations are vulnerable to genetic drift, inbreeding, limited gene flow; thus, assessing their critical in conservation. In this study, we studied black-and-white snub-nosed monkeys (Rhinopithecus bieti) using neutral microsatellites five adaptive major histocompatibility complex (MHC) genes. Two DQA1 alleles, two DQB1 DRB1 DRB5 three DPB1 alleles were...
