AbstractThe Pig-nosed Turtle Carettochelys insculpta (Testudines; Cryptodira; Carettochelyidae) is the sole living representative of the Carettochelyidae. The phylogenetic position of C. insculpta within Testudines has not yet been determined unequivocally. To address this issue, we sequenced the whole mitochondrial DNA (mtDNA) of C. insculpta using the long-and-accurate PCR (LA-PCR) method. The results show that the length of C. insculpta mtDNA is 16 439 bp and its structure is conserved compared to those of other turtles and other vertebrates except the NADH4 gene beginning with an ATC start codon. The 3′-side of the control region in mtDNA has two tandem repeat motifs, each consisting of nine 5′-CA-3′ units and sixteen 5′-AT-3′ units. To assess the phylogenetic position of C. insculpta, Maximum parsimony (MP), Maximum likelihood (ML) and Bayesian (BI) analyses were conducted based on complete mtDNA from 22 taxa. MP analyses robustly supported that the earliest phylogenetic tree splits separated into three basal branches: the Pelomedusidae (Pelomedusa subrufa), the Carettochelyidae (C. insculpta) and an assemblage of 18 cryptodiran turtle species; while ML and BI analyses suggested that Carettochelyidae and Trionychidae formed a clade, and that this clade was the sister taxon to all other cryptodiran turtles.

Abstract Since early in its taxonomic history, placement of the Socorro Wren (Thryomanes sissonii) has been an object of contention. Of particular interest is its current placement in the genus Thryomanes, which makes that genus ditypic and leads to an odd biogeographic scenario for the Socorro Wren's colonization of Socorro Island. We assessed its phylogenetic position by analyzing 516 base pairs of mitochondrial DNA sequences from the ND2 gene of this species and 14 additional wren taxa. Contrary to its present placement, the Socorro Wren is nested phylogenetically within the House Wren species complex, being placed as sister to the clade Troglodytes aedon + T. musculus. The current hypothesis (i.e. sister to Thryomanes bewickii) is strongly invalidated by our analysis. Our analyses indicate that the most appropriate taxonomic classification for the Socorro Wren is Troglodytes sissonii. Posición Filogenética y Ubicación Genérica de Thryomanes sissonii

European newts (genus Triturus) are widely studied, but their phylogeny is not yet unambiguously resolved. Fragments of mitochondrial DNA experiencing different rates of evolution (the ATPase and 12S rRNA genes) were sequenced in order to test a phylogenetic hypothesis derived from biochemical and behavioral data. Well-supported branches of the existing phylogeny gained support in our study. The monophyletic origin of the hypothesized T. boscai – T. italicus clade remained ambiguous, whereas strong support was gained for the sister-taxon relationship of T. vulgaris and T. montandoni. The position of T. vittatus as a sister taxon to the T. marmoratus species group was also supported. The phylogenetic position of T. alpestris could not be clarified. With an in-group taxon sampling denser than in previous molecular phylogenetic studies and under the a priori selection of species from the genera Cynops, Neurergus and Paramesotriton as out-groups, the monophyly of Triturus was strongly supported. It cannot be excluded, however, that the presumed out-group actually belongs to the in-group, rendering Triturus paraphyletic as was concluded from recently published 12S and 16S rRNA sequence data.
