Cover: A stomatopod (Haptosquilla trispinosa) in the mouth of its burrow at Lizard Island, Great Barrier Reef, Queensland, Australia. Many species of Haptosquilla possess conspicuous blue and horizontally polarized visual signals that are apparent on their first maxillipeds. In this issue, How et al. (pp. 3425−3431) examine the evolution of the polarized dimension of this signal, demonstrating a pre-existing bias towards horizontally polarized content. Coupled to polarization having a great efficacy underwater compared with intensity and hue, the study provides an explanation of the complex signal evolution based on both ultimate and proximate selection pressures.

SHORT COMMUNICATION
RESEARCH ARTICLE
In the field: an interview with Martha Muñoz
Martha Muñoz is an Assistant Professor at Yale University, investigating the evolutionary biology of anole lizards and lungless salamanders. In our new Conversation, she talks about her fieldwork in Indonesia, Costa Rica, the Dominican Republic and the Appalachian Mountains, including a death-defying dash to the top of a mountain through an approaching hurricane.
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.
Trap-jaw ants coordinate tendon and exoskeleton for perfect mandible arc
-AntJaws.png?versionId=3942)
Trap-jaw ants run the risk of tearing themselves apart when they fire off their mandibles, but Greg Sutton & co have discovered that the ants simultaneously push and pull the mandibles using energy stored in a head tendon and their exoskeleton to drive the jaws in a perfect arc.
Hearing without a tympanic ear
-Review.png?versionId=3942)
In their Review, Grace Capshaw, Jakob Christensen-Dalsgaard and Catherine Carr explore the mechanisms of hearing in extant atympanate vertebrates and the implications for the early evolution of tympanate hearing.
