Examining the distribution patterns and spatiotemporal niche overlap of sympatric species is crucial for understanding core concepts in community ecology and for the effective management of multi-species habitats within shared landscapes. Using data from 26 camera-traps, recorded over two years (December 2020-November 2022), in Sidi Toui National Park (STNP), Tunisia, we investigate habitat use and activity patterns of the scimitar-horned oryx ( = 1865 captures) and dorcas gazelle ( = 1208 captures). Using information theory and multi-model inference methods, along with the Pianka index, we evaluated the habitat characteristics influencing species distribution and their spatial niche overlap.

- The spread of Neolithic technology and climate changes in the Holocene led to increased human settlements and pastoralism in North Africa, impacting ecosystems.
- Researchers studied the demographic history of the African wolf to see if its population trends corresponded with increased food availability from Neolithic agriculture.
- DNA analysis across Algeria and Tunisia revealed that the African wolf's population grew significantly during the same time domestic livestock expanded, supporting the link between agriculture and wolf population growth.
