Adrenal and metabolic hormones demonstrate risk–reward trade-offs for African elephants foraging in human-dominated landscapes
A key driver of the African savannah elephant population decline is the loss of habitat and associated human–elephant conflict. Elephant physiological responses to these pressures, however, are largely unknown.

Summary
Habitat loss and human–elephant conflict are major threats to African savannah elephants, but their physiological responses to these pressures are not well understood. This study examined how stress (measured by glucocorticoid levels) and metabolism (measured by thyroid hormone levels) in elephants are influenced by human activities, livestock density, and seasonal changes. The findings reveal how elephants balance the risks and rewards of foraging in human-dominated landscapes, offering insights for improved conservation strategies.
