Arboreal environments present considerable biomechanical challenges for animals moving and foraging among substrates varying in diameter, orientation, and compliance. Most studies of quadrupedal gait kinematics in primates and other arboreal mammals…
Sixty skeletons of Callithrix jacchus were examined to identify spondy-loarthropathy. Erosive disease in Callithrix was confirmed as spondy-loarthropathy on the basis of diagnostic sacroiliac erosions, syndesmophyte formation, and the nature and…
Many primates display within-species variation in social organization and mating system. Individuals of these species may be confronted with both the challenges of between-group competition to exclude same-sex competitors as well as within-group…
Presence of spine and sacroiliac involvement and the nature and distribution of the erosive lesions allow definitive diagnosis of spondyloarthropathy. Thus, spondyloarthropathy was identified in Theropithecus, Papio, Cercopithecus, Macaca, Colobus,…
Analyses of New World skeletal populations for the presence of erosions an other osseous alterations and their character, distribution, and radiologic appearance shows that osteoarthritis is predominantly a disease of animals raised in artificially…
