Phylogenetic relationship and characterization of the complete chloroplast genome of the alpine leaf-warbler in Qinghai-Tibet Plateau.

ABSTRACT: The Alpine Leaf-warbler (Phylloscopus occisinensis) is a small-sized and poorly-known songbird endemic to China. In this study, we sequenced and described the whole mitochondrial genome of the Alpine leaf-warbler. The entire mitochondrial sequence was determined by long-range PCR and conserved primer walking approaches. The results demonstrated that the whole mitochondrial genome of P. occisinensis was 16,879 bp in length with 53.1% A + T content; the genome harboured the same gene order as that of other passerine birds, including 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and non-coding control region. The control region (D-loop) of P. rubicilloides include two portions that one was located between tRNA-Gln and tRNA-Phe (219 bp in length) and the other is between tRNA-Thr and tRNA- Pro (1087 bp in length), which is similar to other Leaf-warblers. Phylogenetic analysis indicated that the genome of Phylloscopus species clustered within a clade and is closer related to Aegithalidae species than Paridae species. These mitochondrial data are potentially important for the further studies on molecular evolution and conservation genetics on leaf warbler species.

Project description:The relationship between spatial distribution and phylogeny has been widely debated in recent decades. To understand biogeographic and evolutionary history relationships and to explore the interspecific similarities and phylogenetic correlations of niche characteristics, we collected and recorded all distribution points for eight species of rhubarb on the Qinghai-Tibet Plateau, used different methods to describe the ecological niche, and explored the relationship between phylogeny, ecological niche, and distribution range. The results reveal that: (1) the ranges of optimal environmental variables for species with close kinship are not exactly the same, ecologically similar species are not necessarily sister species, and the overlap of rhubarb has no significant correlation with phylogeny. Therefore, the impact of ecological dimensions on species formation is greater than that of geographical latitude for the eight species of rhubarb. (2) Among the eight species of rhubarb, the breadth of ecological niche is positively correlated with the current suitable habitat area and negatively correlated with fluctuations in future suitable habitat area. In the future, except for Rheum tanguticum and Rheum palmatum, the suitable planting areas for the other six species of rhubarb will decrease as greenhouse gas emissions concentrations and time increase. Therefore, species with smaller ecological niches are at a greater risk of habitat loss compared to species with larger ecological niches. (3) In both existing and future distribution prediction models of rhubarb, we observed that both the widely distributed Rheum spiciforme and the niche narrow Rheum nobile, all eight species of rhubarb are present in the Hengduan Mountains, based on our analysis, we propose that the Hengduan Mountains should be regarded as a priority conservation area for rhubarb, to preserve the species' biodiversity. Our study lays the groundwork for identifying evolutionary trends in ecological specialization.
