The latest research results from the ORANGE project, funded by the National Science Centre Poland (2021/41/B/NZ8/03830), were recently presented at the 57th European Marine Biology Symposium in Naples. The findings revealed significant differences in carotenoid and mercury levels in the diet and blood of little auks from various colonies in Greenland and Svalbard, sparking our interest in further exploration of this topic. We hope to publish the results of this research soon and will be sure to keep you updated.
