Most species have evolved adaptations to reduce the chances of predation.
In many cases adaptations to coexist with one predator generate tradeoffs
in the ability to live with other predators. Consequently, the ability to
live with one predator may limit the geographic distributions of species,
such that adaptive evolution to coexist with novel predators may
facilitate range shifts. In a case study with Enallagma damselflies, we
used a comparative phylogenetic approach to test the hypothesis that
adaptive evolution to live with a novel predator facilitates range size
shifts. Our results suggest that the evolution of Enallagma shifting from
living in ancestral lakes with fish as top predators, to living in lakes
with dragonflies as predators, may have facilitated an increase in their
range sizes. This increased range size likely arose because lakes with
dragonflies were widespread, but unavailable as a habitat throughout much
of the evolutionary history of Enallagma because they were historically
maladapted to coexist with dragonfly predators. Additionally, the traits
that have evolved as defenses against dragonflies also likely enhanced
damselfly dispersal abilities. While many factors underlie the
evolutionary history of species ranges, these results suggest a role for
the evolution of predator-prey interactions.
