Adaptive variation in opsin expression of sticklebacks
from different photic habitats
Our paper Bakker TCM, Hiermes M, Müller B, Martin S, Rennison DJ, Rick IP: "Adaptive variation in opsin expression of sticklebacks from different photic habitats" has been published 2025 in Hydrobiologia. It is about opsin expression in three-spined stickleback and shows that the visual system of stickleback is adapted to their local light environment.
