Adding salt to injuries: Sodium toxicity or limitation of coastal insect communities?

Although central to several physiological processes, sodium seldom receives serious attention in the scientific community as a limiting nutrient in terrestrial ecosystems. Certainly, scientists have previously seen that sodium may be toxic when concentrations are exceedingly high, such as near the coast. The speaker will show you surprising results from a substantial fertilization experiment in a coastal prairie suggesting that certain insects close to the sea may benefit from extra sodium, especially in association with concurrent surges in N and P. Grassland species that see serious sodium deficiencies in their sustenance may often by those most severely limited by sodium.
