Figure 4: Ecological effects of increased environmental N:P ratios.
From: Human-induced nitrogen–phosphorus imbalances alter natural and managed ecosystems across the globe
Number of ‘Web of Science’ studies reporting effects of increased environmental nitrogen availability on increased environmental N:P ratios, number of studies reporting effects of increased environmental N:P ratios on increased organism’s N:P ratios, decreased growth rates and changes in community structure and ecosystem functioning, number of studies reporting effects of increased organism’s N:P ratios on decreased growth rates and changes in community structure and ecosystem functioning, and number of studies reporting effects of decreased growth rates on changes in community structure and ecosystem functioning (References in Supplementary Tables S1–S18). Effects of nitrogen deposition and eutrophication and increased environmental N:P ratios are indicated by continuous lines, effects of increased organisms’ N:P ratios by dashed lines and effects of increased growth rates by dotted lines.
