High microsatellite but no mitochondrial DNA variation in an invasive Japanese mainland population of the parasitoid wasp Melittobia sosui

The paper investigates genetic variation in Melittobia sosui populations, finding no mitochondrial DNA variation in the invasive mainland population but similar microsatellite variation between native and invasive areas.

Dual expansion routes likely underlie the present-day population structure in a Parnassius butterfly across the Japanese Archipelago

This study uses mtDNA and SNP data to trace the dispersal history of Parnassius glacialis across the Japanese Archipelago, identifying two expansion routes and four genetic barriers.
