Abstract
Hantaviruses are harbored by multiple small mammal species in Asia, Europe, Africa, and the Americas. To ascertain the geographic distribution and virus-host relationships of rodent-borne hantaviruses in Japan, Vietnam, Myanmar, and Madagascar, RNAlater™-preserved lung tissues of 981 rodents representing 40 species, collected in 2011-2017, were analyzed for hantavirus RNA by RT-PCR. Our data showed Hantaan orthohantavirus Da Bie Shan strain in the Chinese white-bellied rat (Niviventer confucianus) in Vietnam, Thailand; orthohantavirus Anjo strain in the black rat (Rattus rattus) in Madagascar; and Puumala orthohantavirus Hokkaido strain in the grey-sided vole (Myodes rufocanus) in Japan. The Hokkaido strain of Puumala virus was also detected in the large Japanese field mouse (Apodemus speciosus) and small Japanese field mouse (Apodemus argenteus), with evidence of host-switching as determined by co-phylogeny mapping.

Abstract
Niviventerconfucianussacer Thomas, 1908, which has been regarded as a subspecies of N.confucianus, was found to be a distinct species from N.confucianus based on molecular, karyotyping, and morphological characteristics in this study. Niviventerc.sacer was found to belong to a distinct phylogenetic clade in phylogenetic tree constructed using the mitochondrial gene Cytb, it clustered with N.bukit (Bonhote, 1903) from Vietnam and N.confucianus (Milne-Edwards, 1871) from Yunnan, but showed a distant relationship with N.confucianus from adjacent areas. The genetic distance between N.c.sacer and N.confucianus was more than 5.8%, reaching the level of interspecific differentiation. The species delimitation indicates that N.c.sacer is a monophyletic group. The karyotype of N.c.sacer (FN = 55, 8m+4st+32t+X(sm)Y(t)) differed from that of N.confucianus (FN = 59, 6m+4sm+2st+32t+X(sm)Y(t)). In terms of morphological features, the length of incisive foramen (LIF) and length of auditory bulla (LAB) of N.c.sacer is significantly larger than that of N.confucianus and N.bukit (P < 0.05) and the proportion of white tail tip to total tail length is significantly longer at N.c.sacer (≥ 1/3) than that at N.confucianus (≤ 1/3). Therefore, integrated analysis confirmed that N.c.sacer is a distinct species of genus Niviventer rather than a subspecies of N.confucianus or N.bukit, namely N.sacer, which is only distributed in Shandong.

Abstract
AbstractThe Niviventer fulvescens species complex (NFSC), a group of abundant and taxonomically ambiguous rodent taxa, is distributed from Southeast Asia to south-eastern China. We combined molecular and morphological datasets to clarify the species composition and variation of the NFSC. Our phylogenetic analyses, using molecular data, recovered eight genetic lineages in the NFSC, including a novel, distinct lineage from Jilong, Tibet, China, which is described as a new species, N. fengi sp. nov. The species status of N. fengi is supported by a species delimitation analysis, and it is morphologically distinguished from other members of the NFSC by its greyish dorsal fur, soft hairs covering the whole body and a hairy tail. NFSC species bearing well-developed spines are found at lower elevations. A comprehensive taxonomic revision of the NFSC within China is provided, represented by five species: N. cremoriventer, N. fulvescens, N. huang, N. mekongis comb. nov. and N. fengi. A further study of this species complex, including samples from Southeast Asia, is needed.

Abstract
AbstractMice of the genus Apodemus are widely distributed across Eurasia. Several species of this genus are hosts of important zoonotic diseases and parasites. The evolutionary history and dispersal routes of these mice remain unclear and the distribution of these species in China was poorly explored in previous studies. We here investigate the divergence times and historical geographical evolution of Apodemus and study the taxonomy of species in China by integrating molecular and morphological data. The crown age of this genus is dated to the Late Miocene, approximately 9.84 Mya. Western and Central Asia were inferred as the most likely ancestral area of this genus. Moreover, we recognize nine living species of Apodemus in China: Apodemus uralensis, A. agrarius, A. chevrieri, A. latronum, A. peninsulae, A. draco, A. ilex, A. semotus and A. nigrus sp. nov., the last from the highlands (elevation > 1984 m) of Fanjing Mountain in Guizhou Province and Jinfo Mountain in Chongqing Province. This new species diverged from A. draco, A. semotus and A. ilex approximately 4.53 Mya. The discovery of A. nigrus highlights the importance of high mountains as refugia and ‘isolated ecological islands’ for temperate species in south-eastern China.

Abstract
Species distributed along mountain slopes, facing contrasting habitats in short geographic scale, are of particular interest to test how ecologically based divergent selection promotes phenotypic and genetic disparities as well as to assess isolation-by-environment mechanisms. Here, we conduct the first broad comparative study of phenotypic variation along elevational gradients, integrating a large array of ecological predictors and disentangling population genetic driver processes. The skull form of nine ecologically distinct species distributed over a large altitudinal range (100-4200 m) was compared to assess whether phenotypic divergence is a common phenomenon in small mammals and whether it shows parallel patterns. We also investigated the relative contribution of biotic (competition and predation) and abiotic parameters on phenotypic divergence via mixed models. Finally, we assessed the population genetic structure of a rodent species (Niviventer confucianus) via analysis of molecular variance and FST along three mountain slopes and tested the isolation-by-environment hypothesis using Mantel test and redundancy analysis. We found a consistent phenotypic divergence and marked genetic structure along elevational gradients; however, the species showed mixed patterns of size and skull shape trends across mountain zones. Individuals living at lower altitudes differed greatly in both phenotype and genotype from those living at high elevations, while middle-elevation individuals showed more intermediate forms. The ecological parameters associated with phenotypic divergence along elevation gradients are partly related to species' ecological and evolutionary constraints. Fossorial and solitary animals are mainly affected by climatic factors, while terrestrial and more gregarious species are influenced by biotic and abiotic parameters. A novel finding of our study is that predator richness emerged as an important factor associated with the intraspecific diversification of the mammalian skull along elevational gradients, a previously overlooked parameter. Population genetic structure was mainly driven by environmental heterogeneity along mountain slopes, with no or a week spatial effect, fitting the isolation-by-environment scenario. Our study highlights the strong and multifaceted effects of heterogeneous steep habitats and ecologically based divergent selective forces in small mammal populations.
