Modeled effects of soil acidification on long-term ecological and economic outcomes for managed forests in the Adirondack region (USA) Modeled effects of soil acidification on long-term ecological and economic outcomes for managed forests in the Adirondack region (USA)
Sugar maple (Acer saccharum) is among the most ecologically and economically important tree species in North America, and its growth and regeneration is often the focus of silvicultural practices in northern hardwood forests. A key stressor for sugar maple (SM) is acid rain, which depletes base cations from poorly-buffered forest soils and has been associated with much lower SM vigor...

Can the eastern red-backed salamander (Plethodon cinereus) persist in an acidified landscape? Can the eastern red-backed salamander (Plethodon cinereus) persist in an acidified landscape?
Hardwood forests of eastern North America have experienced decades of acidic deposition, leading to soil acidification where base cation supply was insufficient to neutralize acid inputs. Negative impacts of soil acidity on amphibians include disrupted embryonic development, lower growth rates, and habitat loss. However, some amphibians exhibit intraspecific variation in acid tolerance...

A new look at liming as an approach to accelerate recovery from acidic deposition effects A new look at liming as an approach to accelerate recovery from acidic deposition effects
Acidic deposition caused by fossil fuel combustion has degraded aquatic and terrestrial ecosystems in North America for over four decades. The only management option other than emissions reductions for combating the effects of acidic deposition has been the application of lime to neutralize acidity after it has been deposited on the landscape. For this reason, liming has been a part of...

Application of lime (CaCO3) to promote forest recovery from severe acidification increases potential for earthworm invasion Application of lime (CaCO3) to promote forest recovery from severe acidification increases potential for earthworm invasion
The application of lime (calcium carbonate) may be a cost-effective strategy to promote forest ecosystem recovery from acid impairment, under contemporary low levels of acidic deposition. However, liming acidified soils may create more suitable habitat for invasive earthworms that cause significant damage to forest floor communities and may disrupt ecosystem processes. We investigated...

Watershed-scale changes in terrestrial nitrogen cycling during a period of decreased atmospheric nitrate and sulfur deposition Watershed-scale changes in terrestrial nitrogen cycling during a period of decreased atmospheric nitrate and sulfur deposition
Recent reports suggest that decreases in atmospheric nitrogen (N) deposition throughout Europe and North America may have resulted in declining nitrate export in surface waters in recent decades, yet it is unknown if and how terrestrial N cycling was affected. During a period of decreased atmospheric N deposition, we assessed changes in forest N cycling by evaluating trends in tree-ring...
