张峰博士,是和我合作的第一个博士后。他主要研究弹尾虫的形态分类学。我2007年在昆仑山考察,发现了弹尾虫在特殊生境中驻花、访花的问题,需要有专人研究,但一直苦于找不到合适的合作者。
张峰研究生师从陈建秀教授攻读并获得博士学位,一直从事弹尾虫分类与生物学研究,对分子系统学也有浓厚兴趣。合作至今,虽然由于多种原因,我们没有能够做出来驻花、访花的工作,但是在分子系统学方面有了一些发现。张峰博士就形态性状(如:鳞片)发生和演化,结合形态学数据和分子数据,和国内外同行合作,整理了一篇论文,投稿到分子系统学经典杂志Molecular Phylogenetics and Evolution(MPE)。
该工作于今年1月投稿,审稿时间相对较长,且在我们给编辑部去信咨询进展后,又重新推荐了多位候选审稿人。8月16日晚上收到编辑来信,告知该论文已经被接收(acceptable for publication provided minor revisions are made)。同时,编辑和审稿人也就该工作中存在的问题,点出了可以改进之处,为后续的相关研究提供了新的突破点。我们将尽快完成修改,争取早日在线,和同行分享。
感谢张峰博士和合作者的努力,并祝贺大家的辛勤劳动得到了回报!相信他能在形态分类学和分子系统学的基础上,不断拓展新的思路,获得新的成果。
题目:
Molecular phylogeny shows independent origin of body scales in Entomobryidae (Hexapoda: Collembola)
摘要:
Entomobryidae is the largest family in Collembola but relationships within the family have never been subjected to rigorous phylogenetic analyses. Within the family, body scales are present in many species, and are fundamental in the classification at the subfamilial and tribal levels. A molecular phylogeny was reconstructed using the nuclear 18SrRNA and partial 28SrRNA and the mitochondrial 16SrRNA to examine the evolution of scales across Entomobryidae subfamilies. These datasets were analyzed separately and combined, with parsimony, likelihood and Bayesian algorithms. Monophyly of Orchesellinae was not recovered, and it was split into a scaled clade and an unscaled clade, contradictiing to all recent taxonomic conceptions. The monophyly of Entomobryinae, Seirinae and Lepidocyrtinae is well supported, however within Entomobryinae, the polyphyly of Entomobryini and Willowsiini implies that classificationusing the presence/absence of scales is not valid. Analyses of ancestral character state reconstruction in Entomobryidae indicate that the presence of body scales have evolved independently at least five times, with a loss of scales occurring independently at least twice. A revision of the family Entomobryidae on molecular and morphological basis is clearly needed.
