Professional loggers are key players in the management of the region's forest resource. They are an integral part of a multi-billion dollar wood products industry.ment of the forest resource and help various forest owners meet their myriad objectives. Through a comprehensive, random mail survey of logging fi rms in Wisconsin and Michigan's Upper Peninsula, we offer the fi rst-ever study of this...
There is general agreement that terrestrial systems in the Northern Hemisphere provide a significant sink for atmospheric CO2; however, estimates of the magnitude and distribution of this sink vary greatly. National forest inventories provide strong, measurement-based constraints on the magnitude of net forest carbon uptake. We brought together forest sector C budgets for Canada, the United Sta...
Expansion of Eucalyptus plantation is considered to be one of the major human disturbances to tropical forests, where termites are superabundant and an important decomposer. Here we studied the biomass of dead wood and the abundance and species composition of termites in dead wood in Eucalyptus plantation forest (EF) in Thailand and compared the data with those of the neighboring dry evergreen ...
The Fukushima Daiichi nuclear power plant disaster caused serious radiocesium (137Cs) contamination of forest ecosystems over a wide area. Forest-floor organic layers play a key role in controlling the overall bioavailability of 137Cs in forest ecosystems; however, there is still an insufficient understanding of how forest types influence the retention capability of 137Cs in organic layers in J...
ABSTRACT: The aim of this study is to measure the in-situ carbon dioxide emissions from forest floors in forested and deforested areas in Karasu Forests in Western Black Sea Region of Turkey. Carbon dioxide emissions from forest floors are one of the main reasons of increasing the carbon concentration in the atmosphere. Deforestation, releases CO2 to the atmosphere because carbon stored in the ...
