effects of fat and protein levels on foraging preferences of tannin in scatter-hoarding rodents.both as consumers and dispersers of seeds, scatter-hoarding rodents often play an important role in the reproductive ecology of many plant species. however, the seeds of many plant species contain tannins, which are a diverse group of water-soluble phenolic compounds that have a high affinity for proteins. the amount of tannins in seeds is expected to affect rodent foraging preferences because of their major impact on rodent physiology and survival. however, variable results have been obtained i ...201222808217
effects of random food deprivation and refeeding on energy metabolism, behavior and hypothalamic neuropeptide expression in apodemus chevrieri.maintaining adaptive control of behavior and physiology is the main strategy used by animals in responding to changes of food resources. to investigate the effects of random food deprivation (fd) and refeeding on energy metabolism and behavior in apodemus chevrieri, we acclimated adult males to fd for 4weeks, then refed them ad libitum for 4weeks (fd-re group). during the period of fd, animals were fed ad libitum for 4 randomly assigned days each week, and deprived of food the other 3days. a con ...201627387442
phylogenetic analysis of the complete mitochondrial genome of the korean field mouse apodemus peninsulae (rodentia, murinae) from china.we sequenced and characterized a complete mitogenome (kp671850) of the chinese apodemus peninsulae and compared it with a previously published mitogenome of the korean a. peninsulae (nc016060). the total length of the chinese a. peninsulae mitogenome is 16,457 bp. the mitogenome consists of 13 protein-coding genes (pcgs), two rrna (12s rrna and 16s rrna) genes, 22 trna genes, and one d-loop region. the most common start codon was atg, used in the nine pcgs for initiation. the mitogenomes of chin ...201626006285

A Mitogenome of the Chevrier's Field Mouse (Apodemus Chevrieri) and Genetic Variations Inferred from the Cytochrome b Gene.The Chevrier's field mouse (Apodemus chevrieri) is an endemic species to China and is an important pest in agriculture and human diseases. In this study, the complete mitochondrial genome of this species was sequenced and its size was 16,298 bases (accession no.: HQ896683). The mitogenome structure was similar compared with other reported rodent mitochondrial genomes and includes 13 protein-coding genes, 2 rRNA genes (12S rRNA and 16S rRNA), 22 tRNA genes, and 1 control region. This was the firs ...201121870961
isolation and characterization of 14 microsatellite loci for the chevrier's field mouse (apodemus chevrieri).we describe the isolation and characterization of 14 microsatellite loci in the chevrier's field mouse from genomic dna-enriched libraries. the 14 loci were highly polymorphic with numbers of alleles per locus in 24 individuals ranging from three to 13, observed heterozygosity from 0.381 to 0.867 and expected heterozygosity from 0.448 to 0.931. all loci followed hardy-weinberg expectations except for cfm3, cfm10 and cfm12 loci. no significant linkage association was found among all these loci. t ...200921564765
ectoparasites of chevrier's field mouse, apodemus chevrieri, in a focus of plague in southwest china.chevrier's field mouse, apodemus chevrieri milne-edwards (rodentia: muridae), has been identified as the main wild reservoir of plague in the sylvatic plague focus of yunnan province, southwest china. here, the ectoparasite communities of a. chevrieri and the potential medical and veterinary importance of these ectoparasites are described. a high proportion (66%) of 321 mice were found to be infested with ectoparasites. a total of 81 species of ectoparasite, including 48 species of chigger mite, ...200717897372
