Abstract

The loss or removal of individual species can cause dramatic changes in communities. Experiments indicate that in many communities only a few species will have such strong effects, whereas most will have weak effects owing to small per capita effects and/or low abundance. But extinction of these 'weak' interactors could significantly alter natural communities because they play important stabilizing or 'noise-dampening' roles.
