Although over 40 years of theory have addressed how
evolutionary processes can affect the ecology of
predator­prey interactions, few empirical data have
addressed the same issue. Shertzer et al. and Yoshida
et al. have recently combined manipulative experiments
with mathematical models to demonstrate that evo-
lutionary change in an algal prey strongly affects com-
munity dynamics with their rotifer predator. These
studies contribute to recent developments in community
genetics and the diversity­stability debate.
Population fluctuations in space and time are common in
nature and are important throughout the field of biology,
from human health to conservation. In studying population
dynamics,muchresearchhasaddressedhowpredator­prey
interactions affect population stability. Ecologists typically
