Phylogenetic relationships of Indian caecilians (Amphibia: Gymnophiona) inferred from mitochondrial rRNA gene sequences [PDF]

, 2002
India has a diverse caecilian fauna, including representatives of three of the six currently recognized families, the Caeciliidae, Ichthyophiidae, the endemic Uraeotyphlidae, but previous molecular phylogenetic studies of caecilians have not included ...

Overlooked and misunderstood: A morpho‐molecular revision of Ditrichaceae s.str. (Dicranidae, Bryophyta), with a focus on the Holarctic species of Ditrichum

TAXON, EarlyView.
Abstract We revised the Holarctic taxa of Ditrichaceae on the basis of both organellar DNA sequence data and morphological traits. After the removal of phylogenetically discordant elements related to Flexitrichum and Rhamphidium, the remaining representatives of the family cluster into three well‐supported lineages, which are recognized here as the ...

Diversity of Siphonaria Sowerby I, 1823 (Gastropoda, Siphonariidae) in the Seychelles Bank and beyond

Zoologica Scripta, Volume 52, Issue 1, Page 31-45, January 2023., 2023
Abstract Molecular phylogenetic studies have shown that the characters of the reduced shell of the false limpets of the genus Siphonaria Sowerby I, 1823 are highly variable and often insufficient for species delimitation. The taxonomy and distribution of Siphonaria in the Indian Ocean are poorly known.

Intérêts et limites de l'approche moléculaire pour aborder la biogéographie et la spéciation : l'exemple de quelques Mammifères d'Afrique tropicale [PDF]

Bulletin de la soci\'et\'e zoologique de France 127 (2002) 359-370, 2007
We attempted to test biogeographic hypotheses proposed for the evolution of tropical faunas using mitochondrial DNA sequences of selected African mammalian taxa (Insectivora, Rodentia and Primates). 1/ we constructed a molecular phylogeny of taxa in order to ascertain their monophyly and calibrate a molecular clock; 2/ we analysed and compared the ...

Taxonomy in the light of incongruence: An updated classification of Malvales and Malvaceae based on phylogenomic data

TAXON, EarlyView.
Abstract Malvales is a diverse order of flowering plants, economically and ecologically relevant, and it is known for its broad morphological variability. Recent phylogenomic studies have revealed a complex evolutionary history for the order, including localised phylogenetic discordances among nuclear loci.

Target capture sequencing clarifies key relationships in the Eriostemon group (Rutaceae: Zanthoxyloideae) and supports a reclassification of Philotheca, including the recognition of two new genera

TAXON, EarlyView.
Abstract The Eriostemon group (Rutaceae) is a clade of 16 genera and ~ 209 species endemic to Australia, New Zealand and New Caledonia. Recent efforts to address taxonomic and phylogenetic uncertainty in the group using plastome and nuclear ribosomal DNA sequences have made some progress but have also highlighted problematic areas that require further ...

Cladistic analysis of the genus Malva L. in Iran based on morphological characters [PDF]

زیست‌شناسی کاربردی, 2011
The genus Malva L. with 8 species and 8 varieties in Iran has a wide spread distribution. For studying the cladistic analysis of the species, 18 characters were studied. The characters have entered to the matrix as multistate character.

A chloroplast phylogeny of Arisaema (Araceae) illustrates Tertiary floristic links between Asia, North America, and East Africa [PDF]

, 2004
The evolution of Arisaema is reconstructed, based on combined sequences (2048 aligned bases) from the chloroplast trnL intron, trnL-trnF spacer, and rpl20-rps12 spacer obtained for species from all 11 sections, including sectional type species and ...
