Immediate effects of fire-severity on soil invertebrates in cut and uncut pine forests

摘要: Abstract We studied how variations in fire severity and the degree of cutting before burning affected soil invertebrates a Pinus sylvestris forest central Sweden. A varied depth burn mor layer was obtained by exclusion rain addition fuel small plots (1 m×2 m) clear-cut, selectively cut uncut part large-scale prescribed took place. Soil samples were taken from immediately before, day after, two months after fire. The overall mortality depended on proportion organic consumed fire, for individual taxa it ranged between 59 100%. Invertebrates that lived deeper suffered lesser than those vegetation litter layers did. Greater mobility (Staphylinidae) or thick cuticle (Oribatediae, Elateridae) may have contributed to higher survival observed these taxa. beetles Atomaria pulchra (Cryptophagidae), Corticaria rubripes (Lathridiidae), other fire-favoured insects colonised burned very burned. These species preferred hard-burned stand colonisation. Sixty days abundance lower stands compared stand. composition then characterised few abundant species.
