Geophagy by a large herbivore (capybara, Hydrochoerus hydrochaeris) driven by a human sodium supply — March, 2024

We provide direct evidence of artificial sodium (Na) enrichment driving geophagy by capybaras (Hydrochoerus hydrochaeris), a large herbivore in western Amazonia.

Allometry of sodium requirements and mineral lick use among herbivorous mammals — May, 2023

We found that the use of mineral-licks by large herbivores (e.g., tapirs, monkeys) is related salt (sodium) deficiency and body size, with larger animals being more susceptible to salt deficiency in the western Amazon.
