Social and Seasonal Factors Contribute to Shifts in Male African Elephant (<i>Loxodonta africana</i>) Foraging and Activity Patterns in Kruger National Park, South Africa
African savannah elephants (<i>Loxodonta africana</i>) are well-known as ecosystem engineers with the ability to modify vegetation structure. The present study aimed to examine how male elephant foraging behaviour is affected across (a) season (wet versus dry); (b) time of day (before or...
