Chemical and structural composition of Atlantic Canadian moose (Alces alces) incisors with patterns of high breakage

► Multi-element analysis of 1300 moose incisors using laser ablation ICP-MS. ► Three element groupings explain 50% of tooth composition variation among regions. ► Regional differences in tooth composition. ► Elemental composition does not explain tooth declines in Atlantic Canada. ► Moose resource quality may explain increased incisor tooth breakage patterns.
