	abstract = {<p>Prey animals often face a trade-off between investing time in antipredator behaviour and performing self-maintenance activities, such as foraging. Parents face particularly high stakes as they must protect highly vulnerable offspring while also meeting elevated energetic demands. To optimize this trade-off, the risk allocation hypothesis predicts that prey should adjust their antipredator behaviour to reflect temporal fluctuations in risk. That is, they should invest more in antipredator behaviour when risk is high and prioritize other activities when risk is low. Here we investigate whether changes in risk level resulting from periodic fawn exposure drive maternal vigilance patterns in Thomson\&$\#$39;s gazelle, Eudorcas thomsonii. We find that maternal vigilance patterns match the predictions of the risk allocation hypothesis. Mothers are highly vigilant prior to fawn retrieval, when risk of fawn detection by predators is high. They exhibit low levels of vigilance after fawns resume hiding, when certainty of predator absence is high and, therefore, risk is low. We suggest that fawn active periods may function secondarily as a form of predator sampling and that mothers may adjust their vigilance levels in response to information yielded by this sampling.</p>

	abstract = {<p>Animals often employ multiple sensory modalities for communication and recognition; however, the combination of sensory cues used by individuals in given contexts will vary. Although mother\&ndash;offspring recognition has been widely investigated and is known to be a multimodal process in gregarious mammal species, there is a dearth of information about the interactions between various sensory cues. Here we show how acoustic, olfactory and visual cues are used in a synergistic way in Australian sea lion, Neophoca cinerea, mother\&ndash;offspring recognition. We interpret the results using a cost\&ndash;benefit perspective to disentangle the evolutionary pressures on each component of this communication system. Although olfactory cues can convey individual identity information it was their presence, not their congruency, that prompted female sniffs. We found that calls needed to be from the female\&$\#$39;s own pup for the identification process to be successful, with the information encoded in acoustic cues overriding that of olfactory cues. Despite each sensory cue accurately conveying identity information when presented in isolation, in a multimodal setting their importance, function or role may change and seems to be driven by the costs and benefits of obtaining information resulting from the constraints imposed by the active space of cues.</p>
