Cover: A deer mouse (Peromyscus maniculatus) watching a moonrise over the Blackfoot Valley, MT, USA. There are numerous physiological differences between deer mice that are native to different elevations, but it is not known whether these are genetically based or due to phenotypic plasticity. Cheviron et al. (pp. 1160−1166) and Tufts et al. (pp. 1167−1173) measured the contributions of plasticity to altitude-related physiological differentiation. They found a high degree of plasticity in blood−O2 transport capacity, but, relative to lowland natives, highland mice exhibited a significantly higher thermogenic capacity under hypoxia after controlling for acclimation effects.

The conference will incorporate the JEB Symposium Sensory Perception in a Changing World and the SEB satellite meeting. Find out more and register to join us in March 2025 in Liverpool, UK. Submit your abstract by 17 January 2025. Early-bird registration ends on 17 January 2025.
Extraordinary creatures: mantis shrimp
In our new Conversation series focusing on extraordinary creatures, Tom Cronin and Sheila Patek tell us about the incredible biology of mantis shrimp, from their complex vision to their powerful striking abilities.
Behaviour as a physiological process
In this Commentary, Shamil Debaere & colleagues argue the case for integration of behaviour into animal physiology, and advocate for behaviour to be considered as a physiological process.
Tiny ring-necked snakes keep warm heads despite their size
Some ectotherms are able to raise the temperature of certain body parts above the temperature of other regions & now Christian Fox and Albert Chung, with undergraduates from the University of Virginia, reveal that the heads of tiny ring-necked snakes can be 2.1C warmer than their tails, even though they are only 20cm long.
