Succesional trajectories of eastern deciduous forests driven by invading insects and diseases: Regional analysis
Results/Conclusions - Analyses indicate that regional impacts of these insects on their hosts sometimes occur surprisingly slow but act to change regional forest succession pathways. While emerald ash borer appears to be in the process of quickly eliminating the vast majority of its hosts, impacts of the other species are slower and more subtle on a regional scale. American beech and Eastern hemlock commonly co-occur in late scuccessional forests and in the absence of invading pests, these shade-loving species are increasing in dominance. However, invasions by the adelgid and the scale are reversing successional trajectories and ultimately leading to declines in the dominance, most strongly for Eastern hemlock Such results demonstrate how forest insect invasions can profoundly modify forest dynamic processes, resulting in long-term changes in forest ecosystems.
