Organisms may reduce uncertainty regarding how best to exploit their
environment by collecting information about resource distribution. We
develop a model to demonstrate how competition can facilitate or constrain
an individual’s ability to use information when acquiring resources. Since
resource distribution underpins both selection on information use and the
strength and nature of competition between individuals, we demonstrate
interdependencies between the two that should be common in nature.
Individuals in our model can search for resources either personally or by
using social information. We explore selection on social information use
across a comprehensive range of ecological conditions, generalising the
producer-scrounger framework to a wide diversity of taxa and resources. We
show that resource ecology – defined by scarcity, depletion rate, and
monopolisability – determines patterns of individual differences in social
information use. These differences suggest co-evolutionary processes
linking dominance systems and social information use, with implications
for the evolutionary demography of populations.
