Data from: Trait-mediated indirect interactions: moose browsing increases sawfly fecundity through plant induced responses
1. Induced responses in plants, initiated by herbivory, create potential for trait-mediated indirect interactions among herbivores. Responses to an initial herbivore may change a number of plant traits that subsequently alter ecological processes with additional herbivores. Although common, indirect...

Induced responses in plants, initiated by herbivory, create potential for trait-mediated indirect interactions among herbivores. Responses to an initial herbivore may change a number of plant traits that subsequently alter ecological processes with additional herbivores. Although common, indirect interactions between taxonomically distant herbivores, such as mammals and insects, are less studied than between taxonomically related species (i.e. insect-insect). In terms of mammal-insect interactions, effects on insect numbers (e.g. density) is relatively well studied, whereas effects on performance (e.g. fecundity) are rarely explored. Moreover, few studies have explored mammal-insect interactions on coniferous plants. 2. The aim of this study was to investigate the effect of mammalian induced responses on insect performance. We specifically investigated the effect of moose (Alces alces) browsing on Scots pine (Pinus sylvestris) and subsequent effects on sawfly (Neodiprion sertifer) performance. 3. Sawfly larvae were reared on browsed, clipped and un-browsed control pine trees in a controlled field experiment. Afterwards cocoon weight was measured. Needle C:N ratio and di-terpene content was measured in response to browsing. 4. Sawfly performance was enhanced on trees browsed by moose. Cocoon weight (proxy for fecundity) was 9 and 13 % higher on browsed and clipped trees compared to un-browsed trees. Cocoon weight was weakly related to needle C:N ratio, and browsed trees had lower a C:N ratio compared to un-browsed trees. Needle di-terpene content, known to affect sawfly performance, was neither affected by the browsing treatments nor did it correlate with sawfly weight. 5. We conclude that mammalian herbivory can affect insect herbivore performance, with potential consequences for ecological communities, and with particular importance for insect population dynamics. The measured plant variables could not fully explain the effect on sawfly performance providing a starting point for the consideration of additional plant responses induced by mammalian browsing affecting insect performance.
