Stronger diversity effects with increased environmental stress: A study of multitrophic interactions between oak, powdery mildew and ladybirds.
Recent research has suggested that increasing neighbourhood tree species diversity may mitigate the impact of pests or pathogens by supporting the activities of their milwaukee 2324-21 natural enemies and/or reducing the density of available hosts.In this study, we attempted to assess these mechanisms in a multitrophic study system of young oak (Qu
