Many species of frogs and salamanders, in at least 12 families, alter their timing of hatching
in response to conditions affecting mortality of eggs or larvae. Some terrestrially laid or …

Many animals bear conspicuous warning signals that advertise toxin-mediated
unpalatability to predators; this is known as aposematism. Frogs in particular have evolved …

Eggs often suffer high levels of predation and, compared with older animals, embryos have
few options available for antipredator defence. None the less, hatchlings can escape from …

I examined the role of vibrations in predator-induced early hatching of red-eyed treefrogs,
Agalychnis callidryas. The arboreal eggs of A. callidryas hatch up to 30% early if attacked by …

Pour des proies menacées de prédation, la capacité de distinguer divers degrés de danger
peut avoir d'importantes conséquences sur le fitness. Des larves du triton Notophthalmus …

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 …

Environmentally cued plasticity in hatching timing is widespread in animals. As with later life‐
history switch points, plasticity in hatching timing may have carryover effects that affect …

Variation in fitness generated by differences in functional performance can often be traced to
morphological variation among individuals within natural populations. However …

Predation pressure during early life stages is often high, but few studies have examined
antipredator responses at these stages. We studied the effects of an egg predator (leech …

Many species with complex life histories can respond to risk by adaptively altering the timing
of key life history switch points, including hatching. It is generally thought that such hatching …
