...Jessica R. Rogge; Karen M. Warkentin SUMMARY Plasticity in hatching timing allows embryos to balance egg- and larval-stage risks, and depends on the ability of hatching-competent embryos to continue developing in the egg. Hypoxia can slow development, kill embryos and induce premature hatching...

... entails risk. Red-eyed treefrogs have arboreal eggs and aquatic tadpoles. The embryos use vibrations in snake attacks to cue behaviorally mediated premature hatching, and escape, but vibrations from benign sources rarely induce hatching. Missed cues and false alarms are costly; embryos that fail to hatch...

...Marcie M. Ninness; E. Don Stevens; Patricia A. Wright SUMMARY We investigated the effects of the chorion on movement and growth in rainbow trout ( Oncorhynchus mykiss ) embryos. To test if the chorion restricts movement and growth before hatching, we manually removed the chorion 3–6 days before...

...Karen M. Warkentin; Michael S. Caldwell; J. Gregory McDaniel SUMMARY The embryos of red-eyed treefrogs, Agalychnis callidryas , use vibrations transmitted through their arboreal egg clutch to cue escape hatching behavior when attacked by egg-eating snakes. Hatching early increases the risk...
