Overt soliciting for parental resources, primarily food, is often explained as having evolved to
express the fitness gain a signaling offspring would derive from a favorable parental …

Early developmental conditions can significantly influence the growth and survival of many
animal species. We studied the consequences of exposure to corticosterone (CORT), a …

Traits related to fitness are often pleiotropically linked or otherwise constrained in their
expression. Organisms therefore trade between fitness components such as number and …

Begging is a complex display that is supposed to honestly indicate the need for food of
nestlings, and, usually, parents use this information to adjust their investment in food …

To optimize fitness, organisms may have to trade the number and quality of individual
offspring against their own condition and survival. Limiting micronutrients such as …

Begging signals of offspring are condition-dependent cues that are usually predicted to
display information about the short-term need (ie hunger) to which parents respond by …

Altricial nestlings compete with their nest mates for resources delivered by parents. Parents
may allocate food to nestlings based on reproductive value of offspring. To test the …

Parental care should be selected to respond to honest cues that increase offspring survival.
When offspring are parasitised, the parental food compensation hypothesis predicts that …

Much research on animal communication has addressed how costs or constraints
determined by the oxidative status of an individual can assure the honesty of visual signals …
