Egg-killing Fungus Induces Early Hatching of Red-eyed Treefrog Eggs

Abstract

Pathogens can cause substantial mortality of amphibian eggs. If the timing of hatching is phenotypically plastic, embryos could escape from otherwise lethal infections by hatching early. We tested this with the arboreal eggs of red-eyed treefrogs, Agalychnis callidryas. A filamentous ascomycete (Dothideales: Phaeosphaeriaceae) was present on ;7% of egg… (More)
