Zusammenfassung: | Successful conservation of species that roam and disperse over large areas
requires detailed understanding of their movement patterns and
connectivity between subpopulations. But empirical information on
movement, space use, and connectivity is lacking for many species, and
data acquisition is often hindered when study animals cross international
borders. The African wild dog (Lycaon pictus) exemplifies such species
that require vast undisturbed areas to support viable, self‐sustaining
populations. To study wild dog dispersal and investigate potential
barriers to movements and causes of mortality during dispersal, between
2016 and 2019 we followed the fate of 16 dispersing coalitions (i.e.,
same‐sex group of ≥1 dispersing African wild dogs) in northern Botswana
through global positioning system (GPS)‐satellite telemetry. Dispersing
wild dogs covered ≤54 km in 24 hours and traveled 150 km to Namibia and
360km to Zimbabwe within 10 days. Wild dogs were little hindered in their
movements by natural landscape features, whereas medium to densely
human‐populated landscapes represented obstacles to dispersal.
Human‐caused mortality was responsible for >90% of the recorded
deaths. Our results suggest that a holistic approach to the management and
conservation of highly mobile species is necessary to develop effective
research and evidence‐based conservation programs across transfrontier
protected areas, including the need for coordinated research efforts
through collaboration between national and international conservation
authorities. |
