Related herbivore species show similar temporal dynamics

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