متن کاملEarly colonization of Populus wood by saproxylic beetles (Coleoptera)
The early colonization of newly created coarse woody material (CWM) by beetles was studied in aspen mixedwood forests at two locations in north-central Alberta. Healthy trembling aspen (Populus tremuloides Michx.) trees, in old (>100 years) and mature (40–80 years) stands, were cut to provide three types of CWM: stumps, bolts on the ground (logs), and bolts suspended above the ground to simulat...
متن کاملSHORT COMMUNICATION Impacts of prescribed fire on saproxylic beetles in loblolly pine logs
1. Studies addressing the immediate impacts of fire on forest arthropod communities and their implications for conservation are few, particularly for species within dead wood. To investigate the effects of fire on saproxylic beetles (Coleoptera), we randomly assigned large-diameter loblolly pine (Pinus taeda L.) logs to a forest scheduled for a prescribed burn (i.e. a low-intensity surface fire...
متن کاملEarly Detection of Industrial Emission Impact on Scots Pine
In this work the infl uence of emissions from heat power station on the phenolic composi.tion in scots pine needles was investigated. There was no difference neither in qualitative composition nor in quantitative content. Trees state changes associated with multiple stress factors are reflected in the struc Lure of correl a tion rna tri x. The number of significanCe of correlation coefficients ...
