Graham Scott talks to Big Biology about the oxygen cascade in mice living on mountaintops, extreme environments for such small organisms. In this JEB-sponsored episode, they discuss the concept of symmorphosis and the evolution of the oxygen cascade.

Propose a new Workshop

Our Workshops bring together leading experts and early-career researchers from a range of scientific backgrounds. Applications are now open to propose Workshops for 2024, one of which will be held in a Global South country.

Manipulation of mitochondrial function affects red carotenoid metabolism in a marine copepod

Tigriopus californicus copepods with the most powerful mitochondria are the brightest red, providing an honest and direct link between the attractiveness of a creature and their metabolic prowess.

The physiological cost of colour change

In their Review, Ateah Alfakih, Penelope Watt and Nicola Nadeau discuss the energetic cost of colour change and highlight how this can be avoided or lessened in animals that change colour rapidly or slowly.
