Pikas (Lagomorpha: Ochotonidae) are small mouse-like lagomorphs. To investigate their adaptation to different ecological environments during their dispersal from the Qinghai-Xizang (Tibet) Plateau (QTP), we collected 226 pikas and measured 20 …
Terpenoids, including aromatic volatile monoterpenoids and sesquiterpenoids, function in defense against pathogens and herbivores. Phoebe trees are remarkable for their scented wood and decay resistance. Unlike other Lauraceae species investigated to …
## 摘要
明确的系统发育关系 (phylogeny) 是分类学、进化事件的推断及时间校正、相关性状的祖先状态构建等的重要基础和前提。在明确了不同支系的系统发育关系的前提下,通过分析比较性状在不同类群中的演化历史,可以了解物种经受了哪些选择压力,不同性状是否倾向于共同演化或只是对相同选择压力的适应。自高通量短序列测序技术出现以后,通过广泛采样及使用大规模数据集来研究不同类群的系统发育关系的方法已经成为共识。但由于大规模全基因组测序成本高、分析难度大,简化基因组测序仍具有广泛应用前景。其中,利用转 …
## Background
Phylogenetic relationships among the myriapod subgroups Chilopoda, Diplopoda, Symphyla and Pauropoda are still not robustly resolved. The first phylogenomic study covering all subgroups resolved phylogenetic relationships congruently to …
*Neodon*, genus of a short time evolutionary history, was reported to be diverged from its relatives in early stage of Pleistocene. Only 4 species were well documented in *Neodon* for a long period of time until last years when a systematic work …
Insects are the most speciose group of animals, but the phylogenetic relationships of many major lineages remain unresolved. We inferred the phylogeny of insects from 1478 protein-coding genes. Phylogenomic analyses of nucleotide and amino acid …
