climate change &
heat stress in a changing climate
Antelope on African savannas will need to deal with a drier climate and rising temperatures over the coming years. In this chapter, I study how different heat tolerances and thermoregulation strategies affect roan and gemsbok activities and movements on a daily and seasonal basis.
This study focuses on landscape usage by roan antelope (Hippotragus equinus) and gemsbok (Oryx gazella) in eastern Namibia. This critical habitat is regularly filled with tiny, ephemeral waterholes in the spring, which allow mammals access to broad swathes of lush vegetation inaccessible in the dry season.
My third chapter rests on the incredible maps of ephemeral waterholes that a Duke and WWF joint team (including myself) published in Environmental Research Letters in October of 2022. For a more engaging and visual look at the project, Duke MEM Eliza Carter ('23) created a beautiful ArcGIS Story Map this fall as well.
