Compensatory bone remodelling in moose: a study of age, sex, and cross‐sectional cortical bone dimensions in moose at Isle Royale National Park
Abstract We studied interrelationships among age, sex, and cross‐sectional cortical bone dimensions using quantitative computed tomography (QCT) scans of metatarsal bones of 180 moose ( Alces alces ) that died in Isle Royale National Park, Michigan. As a large‐bodied quadruped with demanding ecologi...
