Increasing effects of chronic nutrient enrichment on plant diversity loss and ecosystem productivity over time
Human activities are enriching many of Earth's ecosystems with biologically limiting mineral
nutrients such as nitrogen (N) and phosphorus (P). In grasslands, this enrichment generally …

Modulation of diversity by grazing and mowing in native tallgrass prairie
Species diversity has declined in ecosystems worldwide as a result of habitat fragmentation,

Nitrogen limitation in dryland ecosystems: responses to geographical and temporal variation in precipitation
DU Hooper, L Johnson - Biogeochemistry, 1999 - Springer
