Saddle long-term nitrogen and phosphorus enrichment: Species composition raw data.
Bowman et al. (1993) have demonstrated that alpine tundra is sensitive to nitrogen and phosphorus additions. Changes in productivity and species composition (belatedly) follow chronic fertilization. Exactly how this response is mediated by changes in precipitation is unknown but can be addressed usi...
