The influence of land reclamation and afforestation on soil arthropods in Iceland
The paper reports the effects of land reclamation and afforestation on soil arthropods in Iceland. Density and group composition of soil arthropods in eroded areas and areas revegetated with birch, lupin and grass species were studied. Results showed that reclamation changed soil animal group compos...
