Cover: Behavioral manipulation occurs when parasites adaptively control the behavior of their hosts in ways that increase parasite fitness. The host behavior becomes an extended phenotype of the parasite (see pp. 142−147). In the zombie ant system, we have snapshots of the interaction as the parasite, a fungus in this case, causes ants to lock their jaws onto leaf veins in forests. Here, a dead green tree ant (Oecophylla smaragdina) from Australia is clamped with the parasite, Ophiocordyceps, which is beginning to grow out from it to eventually reproduce. In this special issue, researchers review and opine on the neurophysiology of such control. Photo credit: David Hughes.Close Modal - PDF Icon PDF LinkTable of contents

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.
