Escape-hatching decisions show adaptive ontogenetic changes in how embryos manage ambiguity in predation risk cues

Jung, Julie; McDaniel, J. Gregory; Warkentin, Karen M. (2021)

As animals develop, their capacities to sense cues, assess threats, and perform actions change, as do the relative costs and benefits that underlie behavioural decisions. We presented ambiguous cues to test if hatching ...
Flexible information sampling in vibrational assessment of predation risk by red-eyed treefrog embryos

Warkentin, Karen M.; Caldwell, Michael S.; Siok, Timothy D.; D'Amato, Alison T.; McDaniel, J. Gregory (2007)

Prey assessing risk may miss cues and fail to defend themselves, or respond unnecessarily to false alarms. Error rates can be ameliorated with more information, but sampling predator cues entails risk. Red-eyed treefrogs ...
Frequency information in the vibration-cued escape hatching of red-eyed treefrogs

Caldwell, Michael S.; McDaniel, J. Gregory; Warkentin, Karen M. (2009)

Incidental acoustic and vibrational cues generated by predators are a potential source of information for prey assessing risk. Substrate vibrations should be excited by most predators, and frequency, amplitude or temporal ...
Frog embryos use multiple levels of temporal pattern in risk assessment for vibration-cued escape hatching

Jung, Julie; Guo, Ming; Crovella, Mark E.; McDaniel, J. Gregory; Warkentin, Karen M. (2022)

Stereotyped signals can be a fast, effective means of communicating danger, but animals assessing predation risk must often use more variable incidental cues. Red eyed-treefrog, Agalychnis callidryas, embryos hatch prematurely ...
Is it safe? Red-eyed treefrog embryos assessing predation risk use two features of rain vibrations to avoid false alarms

Caldwell, Michael S.; McDaniel, J. Gregory; Warkentin, Karen M. (2010)

Prey use predator cues to inform defensive decisions. Detecting these cues is often complicated by benign stimuli that resemble and can be mistaken for predators, leading prey to display costly defences incorrectly. One ...
Temporal Pattern Cues in Vibrational Risk Assessment by Embryos of the Red-Eyed Treefrog, Agalychnis Callidryas

Warkentin, Karen M.; Caldwell, Michael S.; McDaniel, J. Gregory (2006)
