Parthenogenesis has been documented in almost every phylum of animals, and yet this
phenomenon is largely understudied. It has particular importance in dipterans since some …

Recent advances in long-read sequencing technology have allowed for single-molecule
sequencing of entire mitochondrial genomes, opening the door for direct investigation of the …

In most eukaryotic genomes, tandemly repeated copies of 5S rRNA genes are clustered
outside the nucleolus organizer region (NOR), which normally encodes three other major …

In the vast majority of Animalia genomes, the 5S rRNA gene repeats are located on
chromosomes outside of the 45S rDNA arrays of the nucleolar organiser (NOR). We …

Ribosomal DNA (rDNA) has a vital role in ribosome biogenesis as it contains the genes that
encode ribosomal RNA (rRNA) separated by intergenic spacers (IGSs). The rRNA genes …

We have sequenced, assembled, and analyzed the nuclear and mitochondrial genomes
and transcriptomes of Potamopyrgus estuarinus and Potamopyrgus kaitunuparaoa, two …

Once-useful traits that no longer contribute to fitness tend to decay over time. Here, we
address whether the expression of mating-related traits that increase the fitness of sexually …

Why sexual reproduction is so common when asexual reproduction should be much more
efficient and less costly remains an open question in evolutionary biology. Comparisons …

Background: Facultative parthenogenesis and intra-population mixed ploidy are rare in
animals. These unique characteristics allow opportunities to investigate the relationship …

Potamopyrgus antipodarum is a freshwater snail featuring sexual and asexual lineages that
co-exist and compete within the same New Zealand lakes. This provides a unique and …
