Cover: Male túngara frogs (Physalaemus pustulosus) produce courtship calls that are accompanied by conspicuous vocal sac inflation (live male, top panel). Females assess male multimodal signals consisting of a call and vocal sac inflation, although the call is dominant. Using a robotic frog with an inflatable vocal sac (bottom two panels), Taylor et al. (pp. 815−820) showed that when the robofrog's vocal sac was inflated asynchronously with the call, females discriminated against the robofrog. This indicates that although the vocal sac is a secondary signal component, it can strongly modulate mate choice.

Ecotourists feeding grapes on skewers to north Bahamian rock iguanas may be doing the reptiles more harm than good as the sugar charged diet is giving the animals high blood sugar.
Evolution of metabolic plasticity
-MetabolicPlasticity.png?versionId=3667)
In their Commentary, Frank Seebacher and Julian Beaman propose that metabolic plasticity originated in prebiotic protocells and that it was a pre-requisite for effective transfer of genetic material across generations – the hallmark of Darwinian evolution.
