Metasexual Stick Insects: Model Pathways to Losing Sex and Bringing It Back
This chapter illustrates the variety of parthenogenetic mechanisms within three genera of phasmids (stick insects) occurring around the Mediterranean and the close ties between sexuals and asexuals.Expand

Gender-associated mitochondrial DNA heteroplasmy in the venerid clam Tapes philippinarum (Mollusca Bivalvia)
Abstract This paper provides evidence of a gender-associated mitochondrial DNA (mtDNA) heteroplasmy in the clam Tapes philippinarum. The pattern of tissue distribution of the two observed mtDNA typesExpand

Molecular evolution and recombination in gender-associated mitochondrial DNAs of the Manila clam Tapes philippinarum.
Doubly uniparental inheritance (DUI) provides an intriguing system for addressing aspects of molecular evolution and intermolecular recombination of mitochondrial DNA. For this reason, a largeExpand

All-female broods in the butterfly Hypolimnas bolina (L.)
It has been known since 1924 that a proportion of females in the butterfly H. bolina produce only daughters, whereas others produce a 1:1 sex ratio. The present results confirm this, and show alsoExpand

Linkage between sexual and asexual lineages: genome evolution in Bacillus stick insects
The sexually reproducing stick insects Bacillus rossius and B. grandii are sharply differentiated in terms of allozyme gene alleles; B. atticus is a polyclonal automictic parthenogen sister to B.Expand

The mitochondrial cytochrome oxidase II gene in Bacillus stick insects: ancestry of hybrids, androgenesis, and phylogenetic relationships.
Sequencing of a cytochrome oxidase II (COII) gene fragment in Bacillus taxa provided evidence that the bisexual B. rossius is the maternal ancestor of the hybridogenetic B. rossius-grandii strainsExpand

High levels of genetic differentiation between Wolbachia-infected and non-infected populations of Folsomia candida (Collembola, Isotomidae)
Summary The Gram-negative α -Proteobacterium Wolbachia pipientis has been described as an obligate endosymbiont in many arthropod species, where it induces a variety of reproductive alterations,Expand

Cytology of Parthenogenesis in Bacillus whitei and Bacillus lynceorum (Insecta Phasmatodea)
Summary We investigated the maturation divisions of two obligate parthenogenetic natural interspecific hybrids: the diploid B. whitei and the triploid B. lynceorum. B. whitei shows two maturationExpand

The Bag320 satellite DNA family in Bacillus stick insects (Phasmatodea): different rates of molecular evolution of highly repetitive DNA in bisexual and parthenogenic taxa.
The Bag320 satellite DNA (satDNA) family was studied in seven populations of the stick insects Bacillus atticus (parthenogenetic, unisexual) and Bacillus grandii (bisexual). It was characterized asExpand

The Leptynia hispanica species complex (Insecta Phasmida): polyploidy, parthenogenesis, hybridization and more
The Leptynia hispanica stick insect species complex includes bisexuals, triploid and tetraploid parthenogenetic populations, suggesting that polyploidy has played a central role in the evolution ofExpand
