†Potential caterpillar mimicry in a tropical hummingbird — March, 2025

New scientific discovery that the chicks of White-necked Jacobins (Florisuga mellivora) may imitate venomous caterpillars to dissuade hungry predators.

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

Found that artificial sodium (Na) enrichment by human activity explained the geophagy (soil consumption) by capybaras (Hydrochoerus hydrochaeris), a large herbivore in western Amazonia.

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

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