Exotic pests and pathogens, through direct and indirect effects on forest structure and species composition, have the potential to significantly alter forest ecosystem processes, including C cycling. Throughout the northern hardwood forest, beech bark disease (BBD) is causing widespread disruption in forest structure and composition. In the Catskill Mountains of New York, some forests formerly codominated by American beech ( Fagus grandifolia Ehrh.) and sugar maple ( Acer saccharum Marsh.) are shifting to sugar maple dominance. The effects of BBD and a subsequent shift in species composition on annual aboveground net primary production and soil CO2 efflux were examined in eight forest plots selected to represent a gradient of BBD impact. There were no significant trends in aboveground net primary production across this gradient. However, growing season soil CO2 efflux decreased linearly along the BBD gradient, declining by 40%. Although the mechanism controlling this decline is uncertain, the decrease in soil CO2 efflux with BBD impact and a shift to greater composition of sugar maple in litterfall could significantly alter C cycling in northern hardwood stands in the Catskill Mountains.

summarySince the 1940s, horticulturalists (the Lese) have been settled along the sides of the roads that traverse a large part of the forest in eastern Zaire. These people have maintained their lifestyle of shifting cultivation and trade with the Mbuti pygmies. This has resulted in corridors of heavily disturbed and regenerating forest. The results of a study of the understorey bird community at three sites in the Okapi Reserve in the Ituri forest in Zaire are reported here. Two primary forest sites (one monodominant Gilbertiodendron forest) in the Reserve were compared with an area of forest disturbed by shifting cultivation. The two primary forest sites were more similar in species composition than they were to secondary forest created by shifting cultivation. Shifting cultivation had a more severe impact on the bird community than selective logging does in forests in Uganda and Malaysia. There was a shift following disturbance from a bird community dominated by insectivores to one with more frugivore-insectivores and nectarivores. Ground thrushes Zoothera spp. and flycatchers were abundant in the monodominant Gilbertiodendron forest and appear to suffer from the change in forest structure following disturbance. The Okapi Reserve currently conserves some important bird species and at least 333 birds have been reported to occur there.
