Abstract

Managing and conserving populations of large carnivores, including gray wolves Canis lupus, often involves making decisions that balance conflicting stakeholder desires. To help inform these decisions, we developed a microhaplotype amplicon sequencing panel consisting of 341 loci. Of these, 321 were selected from candidates identified through restriction-site associated DNA sequencing (RADseq) with 62 samples collected across Idaho, United States. These loci were selected for high expected heterozygosity in order to inform individual identification and relationship inference. The mean ± SD expected heterozygosity of these loci in a sample of 733 individuals collected in Idaho during 2018–2020 was 0.57 ± 0.09. The 20 additional loci were composed of ten selected for differentiation of western coyotes and wolves, nine selected for differentiation of wolves and domestic dogs, and one locus designed to amplify sry to identify genetic sex. This panel will facilitate monitoring, conservation, and management of gray wolves in the western United States.
