Chatpongcharoen, P., Campera, M., Laithong, P. et al. 2021. Naturalising diet to reduce stereotypic behaviours in slow lorises rescued from wildlife trade. Applied Animal Behaviour Science 242, 105413.
Providing a natural diet is a key component to improving animal welfare and potentially reducing stereotypic behaviours in captivity. Wild slow lorises (Nycticebus spp.) are threatened by illegal wildlife trade, and in Thailand, confiscations from...
Waasdorp, S., Tuffnell, J. A., Bruins-van Sonsbeek, L. et al. 2021. Chopped and dispersed food enhances foraging and reduces stress-related behaviours in captive white-naped mangabeys (Cercocebus lunulatus). Applied Animal Behaviour Science 241,
The white-naped mangabey is an endangered and rare zoo species, yet little is known concerning their welfare in captivity. The assessment of welfare should incorporate a net balance of negative and positive welfare behavioural indicators...
Diana, A., Salas, M., Pereboom, Z. et al. 2021. A systematic review of the use of technology to monitor welfare in zoo animals: Is there space for improvement? Animals 11(11), 3048.
A top priority of modern zoos is to ensure good animal welfare (AW), thus, efforts towards improving AW monitoring are increasing. Welfare assessments are performed through more traditional approaches by employing direct observations and time-consuming...
Alejandro, J., Yamanashi, Y., Nemoto, K. et al. 2021. Behavioral changes of solitary housed female pygmy slow lorises (Nycticebus pygmeaus) after introduction into group enclosures. Animals 11(9), 2751.
Pygmy slow lorises (Nycticebus pygmaeus) are threatened with extinction in the wild. Their nocturnal lifestyle and small size make them difficult to study in their natural habitat, but increasing evidence suggests that they are more...
Fernández-Lázaro, G., Dye, M. H., Eddie,C. et al. 2021. Strepsirrhine primate training programs in North American institutions: Status and implications for future welfare assessment. Animals 11(8), 2462.
Many articles have shown the benefits of operant conditioning training techniques in the care and welfare of several species of nonhuman primates; however, the information regarding their use in strepsirrhine species is scarce. We assessed...
Peploe, J., MacAulay, C. 2021. Laboratory primate enrichment ideas. Animal Technology and Welfare 20(2), 177-183.
There are several items we often use in animal facilities that when finished with are thrown away. However, many of these items come in packaging that can be recycled as enrichment for our animals, particularly...

Melengestrol acetate (MGA) implants are progestin-based reversible contraceptives used to manage fertility in zoo populations. Although it is recommended that MGA implants should be replaced every 2 years, the duration of efficacy has not been...
Robbins, R. L., Sheridan, J. 2021. Effect of enclosure expansion on the activity budgets of eastern black-and-white colobus monkeys, Colobus guereza. Zoo Biology 40(2), 115-123.
Behavior is one of the most observable and informative indicators of animal welfare. This study used behavioral observation methodologies to evaluate the impact of an enclosure expansion on the activity budgets of a group of...
