History and genetic diversity of the most common Antarctic Lichens

Antarctic lichens with different population history show grossly diverging genetic patterns. Above: Antarctic lichens (Usnea) near Carlini station on King George Island, January 2016 (Elisa Lagostina). The Antarctic is arguably the most remote place on Earth and difficult to reach for scientists and other organisms. In many people’s imagination it may just be a vast ice domeContinue reading “History and genetic diversity of the most common Antarctic Lichens”

Caves, biogeography and tiny arachnids

Palpigrades are as precious as pebbles from the Moon … hidden in the deepest fractures of rocks of caves and other kinds of subterranean habitats. Above: A cave-dwelling palpigrade found in an Alpine caves.
