Cover: The decision to pursue a particular sensory cue bears major energy costs. Crespo, Goller and Vickers (pp. 2203−2209) investigated how the pre-flight thermoregulatory behavior of male moths (Helicoverpa zea) (image shows moth shivering with flight muscles, resulting in low amplitude wing movements) is modulated by the presence of different olfactory cues. The presence of conspecific female pheromone stimulates males to generate heat more rapidly but also to take-off with a lower thoracic temperature than males exposed to other odors. A lower thoracic temperature at take-off generates a trade-off between rapid departure and suboptimal flight performance. Photo: J. G. Crespo.Close Modal - PDF Icon PDF LinkTable of contents

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.
