The influence of wood ants on the forest trees growth

Popis výsledku v původním jazyce

Influence of wood ant (Formica polyctena, Foerster) on growth of spruce (Picea abies (L.) Karst.) was studied in Central Bohemia. The ants (Formicidae) represent a frequent member of forest ecosystems they are important predators, support aphid population and honeydew production, and have significant impact on physical, chemical and biological properties of soil. Here we explored affects of ants activity on the soil and forest tree growth using soil analysis and tree-ring analysis. Our research showed that the activity of ants shifts the pH of soil towards the neutral value and increases content of some nutrients in soil (P, K, N). The tree-ring analysis reveals that trees located directly in the ant nest or in the immediate vicinity (within 1 m from the nest) have higher increment of tree-ring widths than trees located in a distance from 5 to 50 m from the nest. However the trees within 1 m from the ant nest have lower increment of tree-ring widths than trees growing on control stands
