Tree species influences diversity of ground-dwelling insects in afforested fields

摘要: Abstract Impaired natural ecosystems, such as agricultural lands, are restored toward original or other target stage. Because the long history has changed physical, chemical and biological features of soil, afforested fields can harbor novel species assemblages interactions. Our overall aim was to quantify diversity ground beetles ants in early successional fields. In a large scale field experiment, we compared plots that had been 25 years ago by planting monocultures birch, pine spruce trees. A total 4080 carabid individuals representing 41 species, 131,933 ant 15 were recorded. Both assemblage included forest open-habitat but dominated generalists, which is typical for habitats. Tree strong influence on assemblages. Species composition among more homogeneous than birch plots. The increased from plots, most likely due positive leaf litter. results indicate rich arthropod these influenced tree already at stages, become prominent succession proceeds. Thus, used afforestation one important factor consideration, if biodiversity objectives.
