Message in a Bottle, Metabarcoding Enables Biodiversity Comparisons Across Ecoregions

D. Steinke, S. L. deWaard, J. E. Sones, N. V. Ivanova, S. W. Prosser, K. Perez, T. W. A. Braukmann, M. Milton, E. Zakharov, J. R. deWaard, S. Ratnasingham, P. D. N. Hebert

This study uses DNA metabarcoding to compare arthropod biodiversity across three Canadian ecoregions, finding greater similarity within ecoregions and a decline in diversity from east to west.
