The diversity and biogeography of the Coleoptera of Churchill: insights from DNA barcoding
Abstract Background Coleoptera is the most diverse order of insects (>300,000 described species), but its richness diminishes at increasing latitudes (e.g., ca. 7400 species recorded in Canada), particularly of phytophagous and detritivorous species. However, incomplete sampling of northern habit...
