High divergence across the whole mitochondrial genome in the “pan-Antarctic” springtail Friesea grisea: evidence for cryptic species?
Collembola are one of the few hexapod groups adapted to live in the harsh environmental conditions of Antarctic terrestrial ecosystems. Diversity is limited to a few species that can be very abundant in coastal deglaciated sites. A remarkable lack of overlap in Collembola species composition is evid...
