Modification of Nitrogen Cycling at the Regional Scale: The Subtle Effects of Atmospheric Deposition
There are two aspects to the problem of subtle human effects on ecosystems. The first is designing scientific studies so as to be able to detect subtle effects (see also Russell, Chapter 8, this volume). The second, and perhaps more difficult, is deciding whether such subtle changes are “bad” and require regulatory correction. In this chapter, I will first present an example of the subtle effects of nitrogen (N) deposition on forest ecosystem function over large areas, and then will attempt to deal with the question of environmental change and its perception by humans.
