Moose (Alces alces) parturition dates, Sweden
In northern environments, the period of access to high-quality forage is limited, exerting strong selective pressure to optimize the timing of parturition. We analysed timing and variation in moose parturition dates of 555 females at 18 study sites across 12ᵒ of latitude (56-68ᵒ N, 1,350 km) in Swed...
