De Vleeschauwer, S., Lambaerts, K., Hernot, S. et al. 2023. Severity classification of laboratory animal procedures in two Belgian academic institutions. Animals 13(16), 2581.

According to the EU Directive 2010/63, all animal procedures must be classified as non-recovery, mild, moderate or severe. Several examples are included in the Directive to help in severity classification. Since the implementation of the...

Clark, F. E. 2022. Bridging pure cognitive research and cognitive enrichment. Animal Cognition 25(6), 1671–1678.

Cognitive enrichment is a growing subset of environmental enrichment for captive animals. However, it has been difficult for practitioners to design, implement, and evaluate relevant and appropriate cognitive challenges. Even though pure comparative cognition researchers...

Clark, F. 2017. Cognitive enrichment and welfare: Current approaches and future directions. Animal Behavior and Cognition 4(1), 52–71.

Cognitive enrichment” is a subset of enrichment that has gained interest from researchers over the past decade, particularly those working in zoos. This review explores the forms of cognitive enrichment that have been attempted for...

Brereton, J. E. 2020. Challenges and directions in zoo and aquarium food presentation research: A review. Journal of Zoological and Botanical Gardens 1(1), 13–23.

From its foundations in agricultural science, zoo animal nutrition has developed into a biologically informed, evidence-based discipline. However, some facets of nutrition still make use of a more traditional approach, such as the field of...

Blois-Heulin, C., Rochais, C., Camus, S. et al. 2015. Animal welfare: Could adult play be a false friend? Animal Behavior and Cognition 2(2), 156–185.

There is no consensus regarding the functions of play. As play behavior is a characteristic of young stages of development, it has been suggested that the higher prevalence of adult play observed in domestic animals...

Alligood, C., Leighty, K. 2015. Putting the “E” in SPIDER: Evolving trends in the evaluation of environmental enrichment efficacy in zoological settings. Animal Behavior and Cognition 2(3), 200–217.

In their seminal paper on environmental enrichment, Mellen and MacPhee (2001) proposed a set of broad goals for enrichment in zoological settings, as well as a framework for enrichment programs. Since that time, the philosophy...

Kinter, L. B., Johnson, D. K., Weichbrod, R. H. et al. 2021. Fit for Purpose assessment: A new direction for IACUCs. ILAR Journal 62(3), 314–331.

The organization and function of the institutional animal care and use committee (IACUC) is the key component of government regulation and oversight of necessary scientific research using live animals and of AAALAC - International accreditation...

Attokaren, M. K., Jeong, N., Blanpain, L. et al. 2023. BrainWAVE: A flexible method for noninvasive stimulation of brain rhythms across species. ENeuro 10(2).

Rhythmic neural activity, which coordinates brain regions and neurons to achieve multiple brain functions, is impaired in many diseases. Despite the therapeutic potential of driving brain rhythms, methods to noninvasively target deep brain regions are...

O’Brien, S. L., Cronin, K. A. 2023. Doing better for understudied species: Evaluation and improvement of a species-general animal welfare assessment tool for zoos. Applied Animal Behaviour Science 264, 105965.

Accredited zoos and aquariums are required to have a welfare assessment process in place for the animals in their care. However, welfare assessment theoretical frameworks and methodologies vary widely. Previous studies have shown that taxonomic...
