Seasonal tropospheric distributions of ozone, carbon monoxide and aerosols and their relationship with sources over southern Africa are compared for two airborne sampling campaigns during southern hemisphere spring 1992 (SAFARI-92) and autumn 1994 (...

We assessed the impact of forest fire on the nesting success of the endemic Red-knobbed Hornbill Aceros cassidix in north Sulawesi, Indonesia. Pre- and post-fire breeding activity was monitored at 60 nest trees. Low rainfall and possible reductions in...
The germination requirements of a broad spectrum of common species found in grassy woodlands and forests in the New England region of northern New South Wales were tested in a series of replicated growth-cabinet experiments. The effects of dark/diurnal...
The role played by the seed coat in seed dormancy of Grevillea linearifolia (Cav.) Druce and G. wilsonii (A. Cunn.) was tested by a series of manipulations in which the seed coat was dissected and removed, dissected and returned to the decoated seed,...
Smoke exposure measurements among firefighters at wildfires in the Western United States between 1992 and 1995 showed that although most exposures were not significant, between 3 and 5 percent of the shift-average exposures exceeded occupational...
Smoke exposure measurements among firefighters during prescribed burns in the Pacific Northwest between 1991 and 1994 showed that a small but significant percentage of workers experienced exposure to carbon monoxide and respiratory irritant that...
Prescribed fire was tested as a potential tool for site preparation and for reducing fire hazard after clearcut logging in dark coniferous forests in Siberia. Experimental burns were conducted on 8 sites to evaluate the practicality of fire use and...
