Anotácia knihy

Atmospheric nitrogen deposition has the potential to §alter species composition and species richness in §grasslands, but until recently the effects of §nitrogen deposition had not been demonstrated at a §large scale. Using sixty-eight grasslands along the §gradient of ambient atmospheric nitrogen deposition §in the UK, this book investigates damage caused by §acidification and eutrophication. The results show §a clear loss of species richness along this nitrogen §deposition gradient. Forbs account for the majority §of this decline, showing reductions in both cover §and abundance along the nitrogen deposition §gradient. Using canonical correspondence analysis, §several individual species are identified as being §positively and negatively associated with nitrogen §deposition. Changes in soil and plant tissue §chemistry are also reported including declines in §soil pH, mobilisation of aluminium, arsenic and lead §in the soil, and increased soil ammonia §concentration along the nitrogen deposition §gradient. This analysis should help shed some light §on the actual impact of nitrogen deposition to semi-§natural grasslands in the UK.
