Pooled Data

The psocid fauna living on spruce branches was studied in northern Finland, both in urban areas near the industrial city of Oulu and in rural surroundings, during the years 1986-88. Samples of about 6000 psocids of 19 species were taken from old and young spruces. The psocid assemblage of the rural area of Taivalkoski differed significantly from other areas according to the pooled data of old spruces. Mesopsocus unipunctatus (Müller), Caecilius burmeisteri Brauer and Trichadenotecnum majus (Kolbe) were most numerous in the most urban areas, Reuterella helvimacula (Enderlein) in the areas characterized by the epiphytic lichen Hypogymnia physodes.

The composition of the invertebrate fauna living on young Norway spruce (Picea abies) branches was studied in northern Finland both in urban and rural areas during the summer months of 1988. Attention was given to the total nitrogen, sulphur and phenolics concentration of the needles. The material consisted of 52627 invertebrates from 300 separate spruce saplings. Mites formed the majority of the invertebrates. Most numerous were Ameronothrus dubinini, Diapterobates humeralis and Ceratoppia bipilis. Springtails and spiders were also numerous. The invertebrate abundances were highest in the urban areas of Isko and Linnanmaa, where the sulphur and nitrogen concentration of the needles was high and the phenolics/nitrogen ratio low. The lowest invertebrate abundances were found in Rusko, the most urban area, and Taivalkoski, the most rural area. Nitrogen and sulphur concentrations were highest at Rusko and lowest at Taivalkoski. Possible reasons for the results are discussed.
