GPS assessment of the use of exhibit space and resources by African elephants (Loxodonta africana).
In public discussions of animal rights and welfare, we as members and proponents of zoological institutions often face significant challenges addressing the concerns of our detractors due to an unfortunate deficiency in systematically collected and published data on the animals in our collections. In the case of elephants, there has been a paucity of information describing their use of space within captive environments. Here, using collar-mounted GPS recording devices, we documented the use of exhibit space and resources by a herd of five adult female African elephants (Loxodonta africana) housed at Disney's Animal Kingdom((R)). We found that dominant animals within the herd used a greater percentage of the available space and subordinate females avoided narrow or enclosed regions of the enclosure that we termed "restricted flow areas." In their use of other resources, dominant females demonstrated increased occupation of the watering hole over subordinate females, but all females demonstrated relatively equivalent use of the mud wallow. Overall, our results provide preliminary evidence that position within the dominancy hierarchy impacts the percentage of space occupied in a captive setting and may contribute to resource accessibility. These findings can be applied to future decisions on exhibit design and resource distribution for this species.
