Based on both morphological and genetic data, we describe a new cryptic species of Calotes from southeastern Xizang Autonomous Region, China. The new species was confused with C. paulus, and it is morphologically most similar to members of the C. paulus complex (namely C. paulus, C. sinyik, and C. zolaiking), but the new species shows considerable genetic divergence from closely resembled congeners and can be diagnosed morphologically by having more vertebral crest scales, more scale rows at mid body, and more caudal vertebrae. With the description of the new species, we also remove C. paulus from the reptile fauna of China.

Culicoides spp. (Diptera: Ceratopogonidae) are vectors of livestock diseases, including bluetongue, Akabane, and African horse sickness. Accurate species identification is a crucial first step in effective vector management.

Using mitochondrial DNA and genome-wide SNP, phylogenetic relationships in were investigated. Phylogenetic analyses based on subregions of mtDNA found possible lineages of several cryptic species, but did not support the phylogenetic relationships of some groups. Phylogenetic analyses based on SNP resulted in the same topology as mtDNA, with some exceptions, and clarified the phylogenetic relationships among all lineages.

Albomycins are unusual sulfur-containing nucleosides from the species of that exhibit potent antibiotic activities against both Gram-negative and Gram-positive bacteria including clinical pathogens. Previous studies demonstrated that the twitch radical SAM enzyme AbmM catalyzes an oxidative sulfur-for-oxygen swapping reaction converting CDP to a 4'-hydroxy-4'-thiocytidine 5'-diphosphate intermediate in the initial step of albomycin biosynthesis. However, the fate of this intermediate in the biosynthetic pathway has remained elusive.

The Millard's rat (), a threatened murid endemic to Southeast Asian montane rainforests and the sole member of its monotypic genus, faces escalating endangered risks as a Near Threatened species in China's Biodiversity Red List. This ecologically specialized rodent exhibits diagnostic morphological adaptations-hypertrophied upper molars and cryptic pelage-that underpin niche differentiation in undisturbed tropical/subtropical forests. Despite its evolutionary distinctiveness, the conservation prioritization given to is hindered due to a deficiency of data and unresolved phylogenetic relationships.
