The mitochondrial genomes (mitogenomes) of bilaterian animals are highly conserved structures that usually consist of a single circular chromosome. However, several species of parasitic lice (Insecta: Phthiraptera) possess fragmented mitogenomes, where the mitochondrial genes are present on separate, circular chromosomes. Nevertheless, the extent, causes, and consequences of this structural variation remain poorly understood. Here, we combined new and existing data to better understand the evolution of mitogenome fragmentation in major groups of parasitic lice. We found strong evidence that fragmented mitogenomes evolved many times within parasitic lice and that the level of fragmentation is highly variable, including examples of heteroplasmic arrangements. We also found a significant association between mitochondrial fragmentation and signatures of relaxed selection. Mitochondrial fragmentation was also associated with changes to a lower AT\%, possibly due to differences in mutation biases. Together, our results provide a significant advance in understanding the process of mitogenome fragmentation and provide an important perspective on mitochondrial evolution in eukaryotes.

Paper in Slovak

English translated title: A survey of Mallophaga in the collections of Andrej Kmet Turcianske Museum in Martin.

Abstract: By 1984, the collection in the musuem has aquired 105 Mallophaga species, belonging to 41 genera.. The material was collected from 78 bird species and 3 mammal species, comprising of 16.38\% of Slovak fauna. Most of the lice species were collected from birds and mammals from the Turcianska hollow and adjacent mountain ranges (23 habitats) and the reminder from other parks of Slovakia (6 habitats).
