Cover: A forcepsfish (Forcipiger flavissimus) patrols its territory on a Hawaiian coral reef. Forcepsfish produce sounds to conspecifics during agonistic interactions such as defense of feeding territories. Boyle and Tricas (pp. 3829−3842) show that sound production is strongly associated with a rapid cranial elevation kinematic pattern or headbob that occurs with synchronous activity from several muscles associated with the cranium and jaws. Sound intensity reflects the size of the signaling fish as well as the fish's ability to rapidly elevate the head. Thus signals may be indicators of the resource holding potential of fish.

INSIDE JEB
In the field: an interview with Wendy Hood
Wendy Hood tells us about her experience of building a mobile laboratory to study mitochondrial function on location.
Is hypoxia vulnerability in fishes a by-product of maximum metabolic rate?
In their Commentary, Andrew Esbaugh and co-authors provide evidence that oxygen supply capacity in some fishes is optimized for performance at low oxygen, and discuss the implications of this finding for calculations of metabolic index.
Determinants of climbing energetic costs in humans
Since our ancient ancestors descended from the trees few of us looked back but now Elaine Kozmer and Herman Pontzer find that despite our terrestrial lifestyle human climbers are just as efficient as our arboreal primate cousins.
