Dynamics of a host–parasitoid interaction clarified by modelling and DNA sequencing
Abstract It has been hypothesised that the 2‐year oscillations in abundance of Xestia moths are mediated by interactions with 1‐year Ophion parasitoid wasps. We tested this hypothesis by modelling a 35‐year time series of Xestia and Ophion from Northern Finland. Additionally, we used DNA barcoding t...
