Cover: Characterised by colourful claws and close-set eyestalks, a female fiddler crab (Uca vomeris) is feeding outside her burrow. These crabs live on intertidal mudflats, where they are vulnerable to predation. Despite carrying their eyes on high 'observation towers' that provide a 360 deg panoramic view, poor resolution and limited depth perception make it difficult to distinguish friends from foes at a safe distance. Fiddler crabs learn, though, to ignore approaching objects they have experienced to be harmless. This process, called habituation, is shown by Raderschall and colleagues (pp. 4209−4216) to be accomplished by associative learning, which is in contrast to the traditional notion of habituation.

In our new Conversation, Harald Wolf talks about his fieldwork experiences working with desert ants in Tunisia to understand their navigation.
Graham Scott in conversation with Big Biology
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.

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.
