Drought's Deadly Paradox: Why More Food Meant Fewer Leopard Cubs

Conventional wisdom suggests drought is good for big cats, as weaker herbivores make for easier meals. However, research from South Africa's Sabi Sands Game Reserve challenges this assumption, revealing a starkly different outcome for lions and leopards.

Scientists observed that during a severe drought, both species enjoyed an increased 'energetic gain' from more vulnerable prey. But for leopards, this benefit was tragically overshadowed. Their reproductive success plummeted as their cubs became more susceptible to intraguild predation—being killed by competing predators. For this subordinate carnivore, the top-down pressure from dominant rivals outweighed the bottom-up advantage of more food.

Lions, the dominant predators, did benefit from the easy hunting and saw a marginal increase in cub survival. Yet even their success was precarious, being offset by a disease outbreak. The findings underscore that a predator's position in the ecological hierarchy is a critical factor in how it copes with the increasing environmental stress of climate change.
