NO3 uptake in shallow, oligotrophic, mountain lakes: The influence of elevated NO3 concentrations NO3 uptake in shallow, oligotrophic, mountain lakes: The influence of elevated NO3 concentrations
Nutrient enrichment experiments were conducted in 1.2-m deep enclosures in 2 shallow, oligotrophic, mountain lakes. 15N-NO3 isotope tracer was used to compare the importance of phytoplankton and benthic compartments (epilithon, surface sediment [epipelon], and subsurface sediment) for NO3 uptake under high and low NO3 conditions. NO3 uptake approached saturation in the high-N lake, but...

Cumulative effects of nutrients and pH on the plankton of two mountain lakes Cumulative effects of nutrients and pH on the plankton of two mountain lakes
We conducted enclosure experiments to examine the cumulative effects of nutrient enrichment and acidification on the plankton of two mountain lakes with differing nutrient conditions. The low-nitrate lake responded to N, N plus acid, and N plus acid plus P additions, showing four- to seven-fold increases in chlorophyll a, increased photosynthetic rate, compositional shifts toward large

Ecological effects of nitrogen deposition in the western United States Ecological effects of nitrogen deposition in the western United States
In the western United States vast acreages of land are exposed to low levels of atmospheric nitrogen (N) deposition, with interspersed hotspots of elevated N deposition downwind of large, expanding metropolitan centers or large agricultural operations. Biological response studies in western North America demonstrate that some aquatic and terrestrial plant and microbial communities are
