A single multiplex of twelve microsatellite markers for the simultaneous study of the brown hare (Lepus europaeus) and the mountain hare (Lepus timidus)

The management of hunted species is challenging, as it must conciliate the conservation of species and their sustainable exploitation. Nongenetic tools are widely used in this context but they may present limitations notably when species can hybridize or when large-scale spatial monitoring is required to establish optimal management actions. This is why genetic tools have been more and more integrated in wildlife management practices. However, the markers proposed are often amplified in small multiplexes when larger ones could allow to better cope with the small quantities of DNA obtained with noninvasive sampling methods. Here, we propose a unique multiplex of 12 autosomal microsatellite markers for the study of two hare species that exist in sympatry in some areas in Europe and are hunted notably in France: the brown hare Lepus europaeus and the mountain hare L.timidus. We tested 17 markers previously used in these two species or other lagomorph species, from which 12 were included in this single multiplex. Diversity was between 4 and 30 alleles per locus totaling 126 alleles, and we showed that these markers possess appropriate genetic resolution for individual and species identification for the populations under study. This multiplex panel represents the largest number of microsatellites amplified in one reaction proposed for these two hare species and provides a cost-effective and valuable tool for further hybridization studies and the management of hares.
