Responses of Forest Ecosystems to Nitrogen Deposition

<p>Despite effective global-scale legislation to restrict the emissions of nitrogen (N) into the atmosphere atmospheric deposition of N remains high in many forested regions. In addition many N-impacted forests still retain the imprint of N saturation such as altered species composition and leaching of essential base cations. Accordingly we need a further understanding of the complexities of N cycling in forest ecosystems and the effects of excess N on forest biodiversity and biogeochemical cycling. This volume explores these complexities including effects on plants plant assemblages and forest biogeochemistry by synthesizing research from Asia Europe and North America. Because of the widespread nature of current declines in N deposition this book ends with a look to the future as N-impacted forests experience a return to lower levels of atmospheric deposition of N.</p>
