Pied tamarins (Saguinus bicolor) are endangered New World primates, and in captivity appear to be very susceptible to stress. We measured cortisol in 214 saliva samples from 36 tamarins and in 227 fecal samples from...
The captive environment can limit some important behavioral options for nonhuman animals, which often results in decreased welfare. The companion of a conspecific can be a source of complexity in captivity, but this aspect has...
Harbor seals in the wild live in a stimulating environment; therefore, nonhuman-animal caretakers have increasingly been using environmental enrichment to improve the well being of seals under human care. The purpose of this study was...
Activity budget comparisons between groups or individuals in the wild and those in captivity are commonly used to determine the range of wild-type behaviors that nonhuman animals in captivity perform. These comparisons are conducted with...
Studies on environmental enrichment for reptiles are lacking in the scientific literature. Although the literature reflects a limited take on reptile enrichment in the zoological community, it may not be the case in reality as...
Standards and policies intended to safeguard nonhuman animal welfare, whether in zoos, farms, or laboratories, have tended to emphasize features of the physical environment. However, research has now made it clear that very different welfare...
Scientists are often reluctant to attribute emotions to nonhuman animals that are similar to human emotions. When the author published her early studies, reviewers prohibited the word fear. Fearful behavior had to be described as...
Devising non-invasive techniques to maintain natural behaviours and increase breeding success of captive populations is a high priority in the conservation of endangered species. Allowing animals to choose their own mates not only preserves behaviours...
The time that penguins devote to aquatic behaviors likely has important implications for their welfare in zoos and aquariums. For decades, field researchers have used time-depth recorders (TDRs) to understand the behavior of penguins at...
Cognitive testing programs are being implemented more frequently in zoo settings due to the benefits these programs can provide for the animals, researchers and zoo visitors. However, the impact that cognitive studies have on the...
