Abstract. The distribution and abundance of organisms are affected by behaviors, such
as habitat selection, foraging, and reproduction. These behaviors are driven by interactions
within and between species, environmental conditions, and the biology of the species in-
volved. Although extensive theoretical work has explored predator­prey dynamics, these
models have not considered the impact of behavioral plasticity and life-history trade-offs
on predicted patterns. We apply a modeling method that allows the consideration of a
spatial, dynamic ecological game between predators and prey using a life-history perspec-
tive. As an illustrative example, we model the habitat selection of Antarctic krill and
