One tunic but more than one barcode: evolutionary insights from dynamic mitochondrial DNA in Salpa thompsoni (Tunicata: Salpida)
This study reports on a novel exception from the pelagic tunicate Salpa thompsoni Foxton. Oozoids caught off South Georgia and the Antarctic Peninsula generated barcodes consisting of a single prominent DNA sequence with some additional, subtler signals of intra‐individual variation. Further investigation revealed this was due to duplicated and/or minicircular DNAs. These could not simply be explained as artefacts or nuclear copies of mitochondrial DNA, but provided evidence for heteroplasmy arising from a dynamic mitochondrial genome. Genetic variation of this sort may allow S. thompsoni to ecologically benefit from ase...

Population genetic structure and demographic history of Streptococcus mutans (Bacteria: Streptococcaceae)
Population genetic studies can contribute to current knowledge about the epidemiology of pathogens such as Streptococcus mutans, which is one of the most widely distributed bacteria in the world to be associated with human dental caries. In the present study, we investigated whether the population genetic structure of the species is clonal or recombinant, and we also evaluated the current levels of gene flow, admixed ancestry, and the hypothesis of an expansion of the bacteria within the last 10 000 years. Strains of S. mutans from Córdoba (Argentina) were obtained, with sequences of the genes aroE, gltA, gyrA, and lep...

Speciation history and species ‐delimitation within the Seychelles Bronze geckos, Ailuronyx spp.: molecular and morphological evidence
Research on the genetic variability across various organisms from the Seychelles granitic islands has revealed considerable differentiation within many taxa, often with deep evolutionary lineages, likely corresponding to cryptic species. Although an accurate description of insular diversity is important for biogeographical and conservation reasons, there is frequently a lack of information even for presumably better known groups, such as vertebrates. One example is the endemic genus Ailuronyx, which includes the emblematic Seychelles giant bronze gecko Ailuronyx trachygaster. In the present study, we investigate, for the f...

On the origin of frictional adhesion in geckos: small morphological changes lead to a major biomechanical transition in the genus Gonatodes
The evolutionary history of vertebrate locomotion is punctuated by innovations that have permitted expansion into novel ecological niches. Frictional adhesion of geckos is an innovation renowned for enabling locomotion on vertical and inverted smooth surfaces. Much is known about the microstructure and function of the fully‐expressed gekkotan adhesive apparatus, although how it originated is poorly understood. Therefore, identifying species that exhibit the earliest stages of expression of frictional adhesion will provide significant insights into the evolution of this trait. Our previous investigation of digital proport...
