The potential connectivity of waterhole networks and the effectiveness of a protected area under various drought scenarios.

Landscape connectivity is considered a priority for ecosystem conservation because it may mitigate the synergistic effects of climate change and habitat loss. Climate change predictions suggest changes in precipitation regimes, which will affect the availability of water resources, with potential co...
