Weight Changes In Wild Wolves, Canis Lupus, From Ages 2 To 24 Months, L. David Mech
USGS Northern Prairie Wildlife Research Center
Weights of 118 female and 141 male Minnesota Wolves (Canis lupus) aged 2-24 months increased almost linearly from about 8 kg for females and 10 kg for males at 3 months to 30 kg for females and 32 kg for males at 10-12 months and then tended to increase much more slowly in an overall curvilinear trend. Considerable variation was apparent for both sexes during their first year.

Risk Factors Associated With Developmental Limb Abnormalities In Captive Whooping Cranes, Cristin Kelley, Barry K. Hartup
Proceedings of the North American Crane Workshop
This retrospective survey identifies potential risk factors for developmental limb abnormalities in whooping crane (Grus americana) chicks reared at the International Crane Foundation between 1990 and 2006. We summarized a series of biologicallyrelevant pre- and post-hatch variables from this population using in-house aviculture and veterinary records, and then compared them between chicks with and without developmental carpal, toe and leg deformities. Chi-square analysis revealed associations between 1) rearing style and each type of deformity, 2) egg source and carpal and toe deformities, and 3) the pre-existence of a toe deformity and carpal and leg deformities. Multivariate analyses using …
