Limb preference, associated with behavioural laterality and hemispheric lateralization, has long received high attention from both ethologists and psychologists. Chinese red pandas in Shanghai Zoo perform natural unimanual actions in two different ways during food handling, making it an appropriate subject to investigate the effect of food handling on pawedness. In this study, we estimated the direction and the strength of pawedness in spontaneous feeding behaviours in zoo-housed Chinese red pandas. All the subjects exclusively used the preferred paw when handling fruit pieces throughout the observational period, with three of them preferred the left paw while the other two the right paw. By contrast, both paws were found to be used alternately in consuming bamboo. Our results indicate that different food manipulations have effects on pawedness in the Chinese red panda where more complex handling could probably enhance its pawedness.

This research examined the efficacy of substituting commercial fish meal (CFM) with meal (PPM) in diets, with and without extract (EHE) supplementation. The study utilized six dietary treatments: a control diet (0% PPM, no EHE) and five experimental diets with varying PPM levels (0%+, 25%+, 50%+, 75%+, and 100%+), each fortified with 300 mg/kg EHE. The experiment spanned 90 days.

Compared with green plants, brown algae are characterized by their ability to accumulate iodine, contributing to their ecological adaptability in high-iodide coastal environments. Vanadium-dependent haloperoxidase (V-HPO) is the key enzyme for iodine synthesis. Despite its significance, the evolutionary origin of V-HPO genes remains underexplored.

Leopard coral grouper (), possessing a distinct red body color, is an important species in commercial markets; however, the high ratio of black individuals under intensive cultivation has limited the commercial value of the species. To dissect the regulatory mechanisms underlying the red skin trait in , gene expression and DNA methylation modifications were compared between red and black skin tissues after astaxanthin treatment. Astaxanthin effectively increased the redness value a* and body weight.
