title: Data from: Related herbivore species show similar temporal dynamics

description: 1.Within natural communities, different taxa display different dynamics in
 time. Why this is the case we do not fully know. This thwarts our ability
 to predict changes in community structure, which is important for both the
 conservation of rare species in natural communities and for the prediction
 of pest outbreaks in agriculture. 2.Species sharing phylogeny, natural
 enemies and/or life history traits have been hypothesized to share similar
 temporal dynamics. We operationalized these concepts into testing whether
 feeding guild, voltinism, similarity in parasitoid community, and/or
 phylogenetic relatedness explained similarities in temporal dynamics among
 herbivorous community members. 3.Focusing on two similar data sets from
 different geographical regions (Finland and Japan), we used asymmetric
 eigenvector maps as temporal variables to characterize species- and
 community-level dynamics of specialist insect herbivores on oak (Quercus).
 We then assessed whether feeding guild, voltinism, similarity in
 parasitoid community, and/or phylogenetic relatedness explained
 similarities in temporal dynamics among taxa. 4.Species-specific temporal
 dynamics varied widely, ranging from directional decline or increase to
 more complex patterns. Phylogeny was a clear predictor of similarity in
 temporal dynamics at the Finnish site, whereas for the Japanese site, the
 data were uninformative regarding a phylogenetic imprint. Voltinism,
 feeding guild and parasitoid overlap explained little variation at either
 location. Despite the rapid temporal dynamics observed at the level of
 individual species, these changes did not translate into any consistent
 temporal changes at the community level in either Finland or Japan.
 5.Overall, our findings offer no direct support for the notion that
 species sharing natural enemies and/or life history traits would be
 characterised by similar temporal dynamics, but reveal a strong imprint of
 phylogenetic relatedness. As this phylogenetic signal cannot be attributed
 to guild, voltinism or parasitoids, it will likely derive from shared
 microhabitat, microclimate, anatomy, physiology or behaviour. This has
 important implications for predicting insect outbreaks and for informing
 insect conservation. We hope that future studies will assess the
 generality of our findings across plant-feeding insect communities and
 beyond, and establish the more precise mechanism(s) underlying the
 phylogenetic imprint.
