Abstract We analysed species richness of plants and true bugs (Insecta, Heteroptera) along a pollution gradient in Scots pine stands in Central Germany. As a consequence of particulate deposition, pH-values of soils increased in the vicinity of the emission source. Therefore, emission increased productivity. Species richness of plants increased with decreasing distance from emission source, and thus with increasing productivity. Similarly, species richness of herbivorous Heteroptera increased with decreasing distance from emission source, whereas, surprisingly, abundance decreased. The proportion of specialised herbivorous bug species is largest in the vicinity of the emission source. Thus, the diversity pattern of herbivores may be explained by the ‘specialisation hypothesis’ and not the ‘consumer rarity hypothesis’. Species richness and abundance of carnivorous Heteroptera showed no significant trend along the gradient. Overall our data favour the ‘bottom-up’ control of species diversity in the analysed system.
