Data incongruence and the problem of avian louse phylogeny [PDF]
Recent studies based on different types of data (i.e. morphological and molecular) have supported conflicting phylogenies for the genera of avian feather lice (Ischnocera: Phthiraptera).

Phylogeny of Miliusa (Magnoliales: Annonaceae: Malmeoideae: Miliuseae), with descriptions of two new species from Malesia [PDF]
The molecular phylogeny of Miliusa (Annonaceae) is reconstructed, with 27 (of ca. 50) species included, using a combination of seven plastid markers (rbcL exon, trnL intron, trnL-F spacer, matK exon, ndhF exon, psbA-trnH spacer, and ycf1 exon ...

Phylogenetic support values are not necessarily informative : the case of the Serialia hypothesis (a mollusk phylogeny) [PDF]
Background: Molecular phylogenies are being published increasingly and many biologists rely on the most recent topologies. However, different phylogenetic trees often contain conflicting results and contradict significant background data. Not knowing how

Since Rifai bring forwarded the first classification of the genus Trichoderma in 1969, the great advances on molecular phylogeny and classification of the genus Trichoderma and it's related teleomorphs have achieved and made considerable change in ...

Molecular timetrees using relaxed clocks and uncertain phylogenies
A common practice in molecular systematics is to infer phylogeny and then scale it to time by using a relaxed clock method and calibrations. This sequential analysis practice ignores the effect of phylogenetic uncertainty on divergence time estimates and

The validity of Pelophylax chosenicus (Okada, 1931) and P. hubeiensis (Fei & Ye, 1982) (Amphibia, Ranidae) [PDF]
Pelophylax plancyi (Lataste, 1880), Pelophylax chosenicus (Okada, 1931) and Pelophylax hubeiensis (Fei & Ye, 1982) were described chronologically from East Asia.

Molecular phylogeny of the Entomophthoromycota
The Entomophthoromycota is a ubiquitous group of fungi best known as pathogens of a wide variety of economically important insect pests, and other soil invertebrates. This group of fungi also includes a small number of parasites of reptiles, vertebrates (including humans), macromycetes, fern gametophytes, and desmid algae, as well as some saprobic ...

Brachiopod Molecular Phylogeny [PDF]
Analysis by parsimony, maximum likelihood and distance methods of newly determined nuclear-encoded SSU rRNA gene sequences from 23 species of articulate brachiopods, six inarticulate brachiopods, two phoronids and an ectoproct, together with other sequences from published and unpublished sources show that lophorates cluster with protostome, not ...

Development of new molecular markers for phylogeny and molecular identification of arbuscular mycorrhizal fungi (glomeromycota) [PDF]
The RPB1 gene was analyzed as a possible new nuclear-encoded molecular marker for the Glomeromycota. New Glomus group A-specific primers were designed and successfully tested on several members of this group. No evidence for genetic variability was found
