Data from: Reproductive success of a keystone herbivore is more variable and responsive to climate in habitats with lower resource diversity
1. The effects of climate on wild populations are often channeled through species interactions. Population responses to climate variation can therefore differ across habitats, owing to variation in the biotic community. Theory predicts that consumer demography should be less variable and less respon...

We used Bayesian analysis to estimate the response of reproductive success to climate in each habitat type, along with residual variation not explained by climate.
