Summary: Summary. There are many ways in which social insect for-
agers may organise the collection of resources and their
transportation back to the nest. One way is to partition the
task into a number of sequential stages in which material is
passed from one worker to another in a relay fashion. This
relatively new concept is known as task partitioning. In this
study, we focus on a particular form of task partitioning,
bucket brigades, which we define as a multistage (i.e., three
or more stages) partitioned transport scheme that uses only
direct transfer between individual workers and without any
predetermined transfer locations, other than the first or last
stages. We first consider the potential costs and benefits of
bucket brigades compared to other transportation schemes.
We then use theory and computer simulation to analyse some
of these aspects in detail. In one empirical study of a bucket
brigade, foragers were generally found to be sequenced from
smallest (near the food source) to fastest (nearest the nest).
This exactly matches what dynamical systems theory would
predict as an ergonomically efficient solution. However, we
also demonstrate that a single and simple local rule larger
