The effects of carbaryl and DDT on the litter fauna of a Corsican pine (Pinus nigra var. maritima) forest: a multivariate comparison.
The effects of two levels of the insecticides carbaryl (0.11 and 1.13 g/m2) and DDT (0.56 and 5.60 g/m2) on the litter fauna of a closed canopy stand of Pinus pinaster (nigra var. maritima) were assessed in Australia. The recovery processes of the animal populations in the litter were followed for 10 months after treatment, and the data from each of four collection intervals were subjected to multivariate analyses. All treatments significantly reduced populations after different intervals, and little over-all recovery occurred during the sampling period.
