	abstract = {Mycetophilids is a species-rich insect group for which the ecological requirements in temperate forests are poorly understood. This study of mycetophilids was based on trap samples from 15 oak-dominated sites in the boreonemoral zone of southern Sweden. Species richness and composition were analysed in relation to environmental variables at a local and at larger scales (multiple regression), and compared to results from similar studies in spruce-dominated sites in the boreal zone of Norway (PCA and two-sample t tests). Regressions showing a dominance of regional factors over local in-site variables agree with species-richness models assuming that local communities most often are unsaturated. Precipitation (inter-correlated with elevation) was the strongest factor for explaining the variation in species-richness, which is consistent with previous results indicating that mycetophilids are disfavoured by drought. In addition to precipitation, the area of mixed forest with high biodiversity values (woodland key habitats and protected areas) was a positive factor for species-richness, probably because such habitats combine elements of both coniferous and deciduous forests. PCA ordination revealed a clear separation of the species composition between boreal and boreonemoral forests. Species-richness in boreal forest was significantly higher than in boreonemoral forest, indicating a preference for boreal habitats in many of the species. For mycetophilids and other drought-sensitive insects, it is suggested that (partial) cutting in some dense successional oak stands should be avoided, and that some invading spruces should be tolerated.

	abstract = {The impact of the weed Tradescantia fluminensis on insect communities, as represented by Malaise-trapped beetles (Coleoptera) and fungus gnats (Diptera: Mycetophilidae s. l.), was studied in three forest fragments. Each fragment contained three plots with and without a dense weed cover. Data on vegetation and habitat variables were collected. Twinspan and Decorana analyses separated the plots by fragment for fungus gnat communities, and nearly so for the presence/absence of beetle species. The fungus gnat communities separated into plots with and without tradescantia at two sites, and there were fewer species of fungus gnats and beetles in tradescantia plots at the site with the simplest habitat structure. The richness of beetle and fungus gnat species was correlated with vascular plant richness. As tradescantia is known to prevent regeneration of many native plants, we predict a corresponding decline in invertebrate diversity and fragment complementarity where the weed is established.},
