How Invertebrates Colonize Deglaciated Sites

20 January 2015, by

Scientists have long wondered how species colonize sites after deglaciation. A recent study by Amber Vater and John Matthews in the journal The Holocene of invertebrates–animals without backbones—on a number of sites in Norway advances the understanding of this colonization.
