● The capacity to find resources is crucial for individuals fitness. To locate them, they can
use two types of information: personal and social.1
●Our biological model, bumblebees, can use both types.
" #$%#&''$(with Netlogo 6.0.4)
●The IBM models pollinators’ daily foraging in a given environment. Pollinators face a partially unknown
environment and compete with conspecifics. Their ability to use different types of information will
change their movement and their foraging efficiency.
●The resource is described by the abundance and the aggregation of flowers.
The success of each pollinator is measured at
the end of the simulation by:
●Nectar quantity collected
●Number of flowers visited%: success (ie, the
bumblebee gets some nectar) & fails (ie, the
bumblebee probe a flower without nectar)
The temporal variation, agregation and the diversity of the flowers will favor the individuals with a high use social information
