Conclusion
Our findings showed how humidity can play an important role in
modulating the life history response of hosts and parasitoids to heat
waves, through a direct effect on the hosts and an indirect effect on
parasitoids. Our results highlight the importance of accounting for
humidity in predicting the population dynamics and distribution of
species in the context of climate change. Furthermore, we emphasised how
interactions between environmental stressors can affect trophic
interactions through different pathways, ultimately modulating the
interactions between species and their responses to the changing
climate. Disentangling the direct and indirect effect of humidity and
heat waves will bring us one step closer to the ability of predicting
community-level responses to climate change.
