Forestry effects on a boreal ground beetle community in spring: Selective logging and clear-cutting compared
To compare the effects of two tree harvesting methods (clear-cutting and single tree selection felling), spring-occurring ground beetles (Carabidae) were studied by pitfall trapping in northern Sweden. Species abundance, total abundance and Hill's diversity indices were used to compare the grou...
