Site characteristics influence Andean bear natal-den selection in dry forest habitat
Abstract: Natal dens are critical for reproduction in bears, yet we know virtually nothing of Andean bear (Tremarctos ornatus) denning ecology, nor whether female Andean bears select dens or denExpand
Tremarctos ornatus (Carnivora: Ursidae)
Abstract: Tremarctos ornatus (F.G. Cuvier, 1825) is a tremarctine bear commonly known as the Andean bear. It is a medium-sized bear with black to dark red-brown pelage with dense, long, coarse fur;Expand
The Andean bear alopecia syndrome may be caused by social housing.
It is suggested that female Andean bears be housed with adult conspecifics only when females choose to cohabitate and that the Andean bear alopecia syndrome is a symptomatic response to the long-term social housing of bears that would otherwise not live socially. Expand
Giant panda twin rearing without assistance requires more interactions and less rest of the mother—A case study at Vienna Zoo
This case-study marks the first successful rearing of giant panda twins in captivity entirely by the mother, and potential favourable factors for the autonomous twin-rearing of a female Giant panda could serve as a model for similar efforts elsewhere. Expand
Selection of trees marked by rubbing by Andean bears in the Peruvian dry forest
Photos provide information on age, but not kinship, of Andean bear
It is demonstrated that the ages of Andean bear cubs ≤6 months old may be estimated from their size relative to their mothers with an average error of <0.01 ± 13.2 days (SD; n = 14), and that ages of adults ≥10 years old may been estimated from the proportion of their nose that is pink with anAverage error is demonstrated.

Relative size and nose color predict age in Andean bears , but their facial markings do not reflect kinship
Using photos of captive Andean bears of known age and pedigree, and photos of wild Andean bear cubs < 6 months old, we evaluated the degree to which visual information may be used to estimate bears’Expand
Factors affecting breeding in captive Carnivora
Captive carnivores pose a challenge for conservationists and institutions alike, presenting many problems that range from diseases to poor welfare and unsuccessful breeding, and further research is needed to fully understand the factors affecting breeding success of captive carnivores. Expand
Variation in the parental care systems of mammals and the impact on zoo breeding programs
The identity of mammalian caregivers, the types of care each may provide to young, and the developmental, ecological, and social factors that influence the amount and distribution of care areExpand
Phylogenetic Constraint in Evolutionary Theory: Has It Any Explanatory Power?
It is suggested that much of evolution may be interpretable through an integrated theory of constraint, and any result or component of the phylogenetic history of a lineage that prevents an anticipated course of evolution in that lineage is defined. Expand
