Dataset used for: Breeding migrations by bighorn sheep males: searching for mates increases vulnerability to hunting

Roxane Lassis, Marco Festa-Bianchet & Fanie Pelletier
In some species where male mating success largely depends on intrasexual competition, males can adopt migratory orresident strategies to seek breeding opportunities. The resulting mixture of resident and migrant tactics within a population can have important ecological, genetic and evolutionary consequences at the metapopulation level. Bighorn sheep Ovis canadensis males establish a linear dominance hierarchy that influences their mating tactics. Some males perform breeding migrations during the pre-rut and rut to seek mating opportunities, but...
