| putting the brakes on a cycle: bottom-up effects damp cycle amplitude. | pest population density oscillations have a profound effect on agroecosystem functioning, particularly when pests cycle with epidemic persistence. here, we ask whether landscape-level manipulations can be used to restrict the cycle amplitude of the european corn borer moth [ostrinia nubilalis (hübner)], an economically important maize pest. we analysed time series from minnesota (1963-2009) and wisconsin (1964-2009) to quantify the extent of regime change in the us corn belt where rates of trans ... | 2012 | 22364256 |
