Extended Data Fig. 9: Trends in leaf tissue nutrient content across latitude.
From: Herbivore effects increase with latitude across the extent of a foundational seagrass
Values represent means of leaf tissue nitrogen (N) and phosphorus (P) content from the control, unmanipulated plots at each site across latitude (°N) (data previously published86). The limitation index (LI) was calculated for each site (see Methods). Note, higher LI values indicate seagrasses that are more nutrient-limited, thus a lower availability of ambient nutrients. For comparison, dashed red and black lines represent mean values from the enriched and unenriched open plots, respectively.
