A molecular phylogenetic analysis of the "true thrushes" (Aves: Turdinae)

The true thrushes (Passeriformes: Muscicapidae, subfamily Turdinae) are a speciose and widespread avian lineage presumed to be of Old World origin. Phylogenetic relationships within this assemblage were investigated using mitochondrial DNA (mtDNA) sequence data that included the cytochrome b and ND2 genes. Our ingroup sampling included 54 species representing 17 of 20 putative turdine genera. Phylogenetic trees derived via maximum parsimony and maximum likelihood were largely congruent. Most of the Turdine taxa sampled can be placed into one of six well supported clades. Our data indicate a polyphyletic Zoothera which can be divided into at least two (Afro-Asian and Austral-Asian) main clades. The genus Turdus, as presently recognized, is paraphyletic but forms a well supported clade with the addition of three mostly monotypic genera (Platycichla, Nesocichla, and Cichlherminia). We identify an exclusively New World clade that includes a monophyletic Catharus, Hylocichla, Cichlopsis, Entomodestes, Ridgwayia, and Ixoreus. Members of the morphologically and behaviorally distinct genera Sialia, Myadestes, and Neocossyphus unexpectedly form a basal clade. Using multiple outgroup choices, we show that this group is distantly related, but unequivocally the sister group to the remaining Turdines sampled. The Turdinae appear to be a relatively old songbird lineage, originating in the mid to late Miocene. If the Turdinae are indeed Old World in origin, our data indicate a minimum of three separate invasions of the New World.     

Molecular systematics of a speciose, cosmopolitan songbird genus: defining the limits of, and relationships among, the Turdus thrushes

The avian genus Turdus is one of the most speciose and widespread of passerine genera. We investigated phylogenetic relationships within this genus using mitochondrial DNA sequence data from the ND3, ND2 and cytochrome b genes. Our sampling of Turdus included 60 of the 65 extant species currently recognized, as well as all four species from three genera previously shown to fall inside Turdus (Platycichla, Nesocichla, and Cichlherminia). Phylogenetic trees based on maximum likelihood and maximum parsimony algorithms were congruent. Most of the Turdus taxa sampled fall into one of four clades: an African clade, a Central American-Caribbean clade, a largely South American clade, and a Eurasian clade. Still other taxa are placed either at the base of Turdus, or as links between clades. In no instance is any continent reciprocally monophyletic for the species distributed on it. A general lack of nodal support near the base of the phylogeny seems related to a rapid intercontinental establishment of the major clades within Turdus very early in the history of the genus. The monotypic genus Psophocichla is distantly related to, but clearly the sister of, Turdus rather than a constituent member of it.     

A molecular phylogenetic analysis of the family Rhacophoridae with an emphasis on the Asian and African genera

Using characters from mitochondrial DNA to construct maximum parsimony and maximum likelihood trees, we performed a phylogenetic analysis on representative species of 14 genera: 12 that belong to the treefrog family Rhacophoridae and two, Amolops and Rana, that are not rhacophorids. Our results support a phylogenetic hypothesis that depicts a monophyletic family Rhacophoridae. In this family, the Malagasy genera Aglyptodactylus, Boophis, Mantella, and Mantidactylus form a well-supported sister clade to all other rhacophorid genera, and Mantella is the sister taxon to Mantidactylus. Within the Asian/African genera, the genus Buergeria forms a well-supported clade of four species. The genera, except for Chirixalus, are generally monophyletic. An exception to this is that Polypedates dennysii clusters with species of Rhacophorus, suggesting that the taxonomy of the rhacophorids should be revised to reflect this relationship. Chirixalus is not monophyletic. Unexpectedly, there is strong support for Chirixalus doriae from Southeast Asia forming a clade with species of the African genus Chiromantis, suggesting that Chiromantis dispersed to Africa from Asia. Also, there is strong support for the sister taxon relationship of Chirixalus eiffingeri and Chirixalus idiootocus apart from other congeners.     

基于线粒体Cyt b基因的线蛱蝶亚科的系统发育

基于线粒体Cytb基因部分序列,以波蛱蝶为外群,采用邻接法、最大简约法和贝叶斯法分别构建了中国线蛱蝶亚科10属25种蝶类的系统发育树,探讨了各主要类群间的系统发育关系。其结果表明,所有线蛱蝶亚科聚为两大枝:第一枝包括环蛱蝶属、菲蛱蝶属、蟠蛱蝶属和缕蛱蝶属,其中缕蛱蝶属与环蛱蝶族亲缘关系较近;第二枝包括丽蛱蝶属、穆蛱蝶属、线蛱蝶属、带蛱蝶属、律蛱蝶属和翠蛱蝶属,其中线蛱蝶属为非单系群,翠蛱蝶属和律蛱蝶属则为单系发生,并构成姐妹群。     

Nuclear and mitochondrial DNA evidence of polyphyly in the avian superfamily Muscicapoidea

Nucleotide sequences of the nuclear c-mos gene and the mitochondrial cytochrome b and ND2 genes were used to assess the monophyly of Sibley and Monroe's [Distribution and Taxonomy of Birds of the World, Yale University Press, New Haven, 1990] Muscicapoidea superfamily. The relationships and monophyly of major lineages within the superfamily, as well as genera membership in major lineages was also assessed. Analyses suggest that Bombycillidae is not a part of Muscicapoidea, and there is strongly supported evidence to suggest that Turdinae is not part of the Muscicapidae, but is instead sister to a Sturnidae+Cinclidae clade. This clade is in turn sister to Muscicapidae (Muscicapini+Saxicolini). Of the 49 Turdinae and Muscicapidae genera that we included in our analyses, 10 (20%) are shown to be misclassified to subfamily or tribe. Our results place one current Saxicolini genus in Turdinae, two Saxicolini genera in Muscicapini, and five Turdinae and two Muscicapini genera in Saxicolini; these relationships are supported with 100% Bayesian support. Our analyses suggest that c-mos was only marginally useful in resolving these "deep" phylogenetic relationships.     

An evaluation of the monophyly of Massarina based on ribosomal DNA sequences

The monophyletic status of the genus Massarina was evaluated on the basis of phylogenetic analysis of the partial small subunit gene (SSU), internal transcribed spacers (ITS 1 & 2), and 5.8S gene sequences of the ribosomal DNA. Species of Massarina used in the study clustered into two distinct clades with high bootstrap support in trees generated from maximum parsimony, weighted parsimony, maximum likelihood, and neighbor-joining analyses. The hypothesis that Massarina species belong to a phylogenetically monophyletic group is rejected. Species with narrowly fusiform ascospores form a monophyletic clade with Lophiostoma, a genus highly similar in morphology. The five species currently accepted in Massarina with such spore morphology are here transferred into the genus Lophiostoma. Massarina species with broadly fusiform to ellipsoidal ascospores are retained as Massarina s. str., lectotypified by M. eburnea. Massarina walkeri is presently excluded from both Massarina and Lophiostoma. The transfer of M. papulosa to a new genus Oletheriostrigula is verified.     

A phylogenetic analysis of the genera of Lejeuneaceae (Hepaticae)

The Lejeuneaceae are the largest family of the liverworts (Hepaticae), with almost a thousand species in 91 currently accepted genera. We analysed phylogenetic relationships of 69 genera, representing all major subfamilies and tribes recognized in the family, by using 49 informative morphological characters (31 gametophytic, 18 sporophytic), one chemical character, and applying equal and successive weighting of characters and parsimony analysis. In all trees recovered, the Lejeuneaceae were monophyletic with Nipponolejeunea (subfam. Nipponolejeuneoideae) forming the basalmost lineage. The remaining genera clustered in two major groups, the monophyletic Lejeuneoideae (52 genera) and the paraphyletic Ptychanthoideae (16 genera). Within each, several multigeneric lineages corresponding in part to previously described taxa were recovered: the Acrolejeuneinae and Ptychanthinae clades in the Ptychanthoideae, and the Brachiolejeuneinae, Lejeuneeae and Tuyamaella–Cololejeunea clades in the Lejeuneoideae. Bryopteris , a genus sometimes treated as a separate family, was nested in the Ptychanthinae clade. The Tuyamaella–Cololejeunea lineage corresponded with three previously recognized subfamilies (Cololejeuneoideae, Myriocoleoideae and Tuyamaelloideae) and contained genera with neotenic features, in two subclades. These features seemed to have originated by multiple heterochronic events: single origins were detected for 'protonemal neoteny' and 'primary neoteny', whereas 'secondary neoteny' probably evolved twice. Relationships within the large Lejeuneeae clade (43 genera) remained largely unresolved, although several putative lineages were detected in majority rule trees. Additional characters such as DNA sequences may provide better phylogenetic resolution in this group.  © 2003 The Linnean Society of London, Botanical Journal of the Linnean Society , 2003, 143 , 391–410.
