  The column headers refer to: - SamplingCode: WSL fauna database code referring to year and trap type (not relevant) - SamplingDate: Date when the emergence traps were emptied, corresponds roughly to the date of emergence - TreeNumber: Tree ID - Defoliation: percentage of needle loss or crown transparency, according to international standards, of the trees prior to felling - BarkSurface: bark surface area of stem parts exposed in emergence traps - YearOfAttack: Year of colonization. Technically, the colonization window opened on 1st of January and closed in June, when sections of the tree stems were transported to the institute - YearOfEmergence: Emergence year of a given cohort of insects in the greenhouse - YearAfter Attack: Temporal difference between year of colonization and year of emergence of a given cohort of insects, corresponding to total development time - Region: AO Aosta (ITA), GR Grisons (CH), VS Valais (CH) - Location: locality nearest to the gradient - Elevation: Site where trees were felled and exposed to colonization - Aspect: north (N) or south (S) facing slope - Species: taxonomic species according to Fauna Europaea - Family: taxonomic family - Order: taxonomic order: Col. Coleoptera, Hym. Hymenoptera, Dipt Diptera, Raph Raphidioptera - Guild: Phyto phytophagous, Pred predatory, para parasitoid - Number: number of sampled individuals of a given species at a given date. - Density: number of emerged insects per m2 bark surface - Identifyer: specialist who identified the insects
