Dear colleagues, I’m happy to announce our new publication: Jaakkola, K. (2024). Minding the minds: A primer on cognitive challenge for marine mammals in human care. Animals, 14, 949. https://doi.org/10.3390/ani14060949 Abstract: The past several decades have witnessed significant improvement in the physical welfare of marine mammals in zoos and aquariums. Over that same time period, research has revealed complex cognitive abilities in at least some of these species, yet there has been comparatively little attention paid to addressing their cognitive welfare per se. Studies primarily conducted with terrestrial animals have suggested that providing appropriate cognitive challenges in managed care settings can improve animal well-being. As a step toward facilitating this practice with marine mammals, this paper discusses factors relevant for creating appropriate cognitive challenges, outlines the three major categories of cognitive challenge that have been utilized with marine mammals, along with the logistical pros and cons of each, and calls on organizations that care for marine mammals to cultivate a bias for action with respect to providing cognitive care. The paper is open access, available here: https://www.mdpi.com/2076-2615/14/6/949 All the best, Kelly Kelly Jaakkola, PhD Director of Research Dolphin Research Center
