Getting to the Meat of It: The Effects of a Captive Diet upon the Skull Morphology of the Lion and Tiger
Zoo animals are crucial for conserving and potentially re-introducing species to the wild, yet it is known that the morphology of captive animals differs from that of wild animals. It is important to know how and why zoo and wild animal morphology differs to better care for captive animals and enhance their survival in reintroductions, […]
A Ten-Stage Protocol for Assessing the Welfare of Individual Non-Captive Wild Animals: Free-Roaming Horses (Equus Ferus Caballus) as an Example
Knowledge of the welfare status of wild animals is vital for informing debates about the ways in which we interact with wild animals and their habitats. Currently, there is no published information about how to scientifically assess the welfare of free-roaming wild animals during their normal day-to-day lives. Using free-roaming horses as an example, we […]
An investigation into keeper opinions of great ape diets and abnormal behaviour
Zoos are evidencing a shift in great ape diets to cultivated fruit-free to achieve a more wild-type nutritional composition (lower sugar, higher fibre). This study aimed to ascertain great ape keeper knowledge and opinions on the removal of cultivated fruit from great ape diets, to investigate feeding regimes currently in use and to understand the […]
Hematology and Plasma Biochemistry Value Differences Between Acclimated and Recently Captive Female Southern Stingrays, Dasyatis americana
Southern stingrays are used for interaction and education in captive and wild settings therefore it is important to monitor their health conditions. Diagnostic tools that are useful for assessing health in other animals include hematology and plasma biochemistry profiles. Certain reference intervals have been established in this species; however, interpretation of intervals in stingrays under […]
On Comparing the Behaviour of Zoo Housed Animals with Wild Conspecifics as a Welfare Indicator, Using the Giraffe (Glraffa Camelopardalis) as a Model
To assess the validity of using wild behavioural data as a welfare indicator for zoo animals, the time budgets of 19 captive giraffe (Giraffa camelopardalis), from four zoos were compared with the time budgets of wild giraffe from Hwange National Park, Zimbabwe. Differences were shown to exist between the behaviour of wild and captive giraffe. […]
On Comparing the Behaviour of Zoo Housed Animals with Wild Conspecifics as a Welfare Indicator
It is commonly assumed that animals suffer if they cannot perform behaviours seen in wild conspecifics. Although comparisons with the behaviour of wild conspecifics are a popular method of assessing the welfare of captive animals, their validity has not been fully assessed. Homeostatic models of motivation suggest that many behaviours are stimulus driven rather than […]
Catching the Spirit: A Study of Bureau of Land Management Wild Horse Adopters in New England
Between 1971 and 2009, the U.S. Bureau of Land Management (BLM) adopted out nearly 225,000 horses and burros in the wild (wild horses and burro) who were removed from public lands (BLM, 2009). The inability of the BLM to adopt out wild horses as quickly as they are removed and recurring reports that many wild […]
Behavioral and Hormonal Consequences of Transporting Giant Pandas From China to the United States
Zoological institutions strive to ensure the welfare of nonhuman animals in captivity. Part of this effort involves reducing the level of distress experienced by an animal to the greatest extent possible. However, some necessary zoo management practices such as transportation induce stress responses. An extensive literature exists concerning the animal welfare implications of road transportation […]
Behavioral effects of an immunocontraceptive vaccine on eastern fox squirrels
Managing pest species in urban and suburban areas is challenging, and contraception may provide a socially acceptable and effective management option for many species. The immunocontraceptive vaccine, GonaCon, effectively inhibits reproduction in many species of wildlife, but the behavioral effects are not yet well understood. Contraceptive-induced changes in behavior could raise animal welfare concerns and […]
Ultrasonographic adrenal gland findings in healthy semi-captive cheetahs (Acinonyx jubatus)
Cheetahs in captivity are believed to suffer from stress predisposing them to poor health. To date fecal glucocorticoids have been used as a non-invasive indicator of chronic stress. This study examines, the feasibility of transabdominal adrenal gland ultrasonography in cheetahs and determined normal adrenal measurements that can potentially be used as a more reliable indicator […]
