Our cover for issue 12 shows a green-eyed tree frog in Birthday Creek, Paluma, Queensland (photo credit: Richard Duffy). Frogs and other amphibians are susceptible to  chytridiomycosis (caused by Batrachochytrium dendrobatidis (Bd)), which has taken a heavy toll on amphibian populations. In this issue, Greenspan et al’s paper Realistic heat pulses protect frogs from disease under simulated rainforest frog thermal regimes suggests that even where average temperatures are suitable for fungal growth and reproduction, infection risk and the outcome of existing infections may be heavily influenced by mild heat spikes only slightly higher than Bd’s thermal limits, providing support for management interventions that promote warm microenvironments for hosts.
