ABSTRACT
Resistance is not futile
The fungal disease chytridiomycosis has wreaked havoc on amphibians worldwide. The disease is caused by the organism
Batrachochytrium dendrobatidis
and was first identified in the late 1990s. Voyles
et al.
revisited protected areas in Panama where catastrophic amphibian losses were recorded a decade ago (see the Perspective by Collins). Although disease theory predicts that epidemics should result in reduced pathogenicity, they found no evidence for such a reduction. Despite this, the amphibian community is displaying signs of recovery—including some species presumed extinct after the outbreak. Increased host resistance may be responsible for this recovery.
