Morphological change in Newfoundland caribou : Effects of abundance and climate

  title={Morphological change in Newfoundland caribou : Effects of abundance and climate},
  author={Shane P. Mahoney and Jackie N. Weir and J. Glenn Luther and James A. Schaefer and F. Shawn and Morrison},
The demographic and environmental influences on large mammal morphology are central questions in ecology. We investigated the effects of population abundance and climate on body size and number of male antler points for the La Poile and Middle Ridge caribou (Rangifer tarandus, L. 1758) herds, Newfoundland, Canada. Across 40 years and 20-fold changes in abundance, adult males and females exhibited diminished stature as indicated by jawbone size (diastema and total mandible length) and the number… CONTINUE READING
