Abstract: Digestive plasticity is recognized as an adaptive trait that enables individuals to cope with variations in the quality of food resources. We compared the digestive morphology and the digestibility of woody browse of introduced deer from Anticosti Island and deer from the mainland source population. Several measurements of the digestive organs of deer from Anticosti Island were larger compared to the continental deer. However, no clear differences were detected in plant digestibility between the two populations. Digestive plasticity, especially at the rumen-reticulum scale, appears to play a central role in the digestive response to low-quality food conditions faced by deer on Anticosti Island and probably contributes to improve digestive efficiency.
