Leeds, A., Riley, A., Terry, M. et al. 2022. Out of sight, out of mind or just something in the way? Visual barriers do not reduce intraspecific agonism in an all-male group of Nile crocodiles (Crocodylus niloticus). Animals 12(3), 269.

Here, we evaluated if visual barriers could reduce intraspecific agonism in an all-male group of Nile crocodiles (Crocodylus niloticus) living in a zoo. Crocodiles were monitored for nearly 100 h, and four “hotspots” of aggression...

Rana, M. S., Lee, C., Lea, J. M. et al. 2022. Commercial free-range laying hens’ preferences for shelters with different sunlight filtering percentages. Animals 12(3), 344.

Extreme sunlight might be aversive to free-range laying hens, discouraging them from going outside. Range enrichment with artificial shelters may protect hens from sunlight and increase range use. The preferences of 34–40-week-old Hy-Line Brown laying...

Sans, E. C. de O., Tuyttens, F. A. M., Taconeli, C. A. et al. 2021. From the point of view of the chickens: What difference does a window make? Animals 11(12), 3397.

We aimed to investigate what broiler chickens prefer when given free choice between a barn side with artificial lighting only as opposed to the other barn side with natural light through glass windows and artificial...

Ludwiczak, A., Skrzypczak, E., Składanowska-Baryza, J. et al. 2021. How housing conditions determine the welfare of pigs. Animals 11(12), 3484.

Humans who care for pigs prefer an environment that not only allows the pigs to express their natural behaviors but also limits the development of aggression and stereotypes. Most of the behavioral and health problems...

Spangenberg, E., Wallenbeck, A., Eklöf, A.-C. et al. 2014. Housing breeding mice in three different IVC systems: Maternal performance and pup development. Laboratory Animals 48(3), 193–206.

A proper cage environment is essential for the welfare of laboratory mice, especially for females during the energy demanding lactation period and for pups during early development and growth. The most common housing system for...

Fischer, C. P., Romero, L. M. 2019. Chronic captivity stress in wild animals is highly species-specific. Conservation Physiology 7(1), coz093.

Wild animals are brought into captivity for many reasons—conservation, research, agriculture and the exotic pet trade. While the physical needs of animals are met in captivity, the conditions of confinement and exposure to humans can...

Lauderdale, L. K., Shorter, K. A., Zhang, D. et al. 2021. Habitat characteristics and animal management factors associated with habitat use by bottlenose dolphins in zoological environments. PLOS ONE 16(8), e0252010.

The way an animal uses its habitat can serve as an indicator of habitat appropriateness for the species and individuals. Bottlenose dolphins (Tursiops truncatus and Tursiops aduncus) in accredited zoos and aquariums experience a range...

Miller, L. J., Lauderdale, L. K., Mellen, J. D. 2021. Relationships between animal management and habitat characteristics with two potential indicators of welfare for bottlenose dolphins under professional care. PLOS ONE 16(8), e0252861.

Accredited zoos and aquariums continually strive to ensure high levels of animal welfare for the animals under their professional care. Best management practices include conducting research to better understand factors that lead to optimal welfare...

Falendysz, E. A., Calhoun, D. M., Smith, C. A. et al. 2020. Outside the box: Working with wildlife in biocontainment. ILAR Journal 61(1), 72-85.

Research with captive wildlife in Animal Biosafety Level 2 (ABSL2) and 3 (ABSL3) facilities is becoming increasingly necessary as emerging and re-emerging diseases involving wildlife have increasing impacts on human, animal, and environmental health. Utilizing...
