A study of pregnant wild hares published in the November "Journal of Animal Ecology" found that any kind of stress, not just fear of predators, caused a similar decrease in reproductive efficiency.
BBC - GCSE Bitesize: Predators and their prey
Lynx Cycles For the lynx, feast rapidly turns into famine. After a year or two of decline, the hare population bottoms out and starvation starts stalking the cats. At first, they make do with rodents, squirrels and wild birds; but in terms of both quantity and quality, this prey is inadequate. When their nutritional needs aren't being met, lynx can't maintain the reserves of body fat necessary to survive in the cold climate.
They're more vulnerable to predation and starvation, and the females can't provide their kittens with enough nourishment during gestation and afterward.

According to the government of the Northwest Territories, such declines in lynx populations typically last three to five years.
When food plants grow back unimpeded, and the hare population accordingly recovers, the lynx population follows suit. The Global Warming Factor Lynx expert Stan Boutin of the University of Alberta is concerned about the impact global warming will have on lynx-snowshoe hare cycles.
Among three genetically distinct lynx subspecies isolated from each other by the Rocky Mountains or long distances, some pursue hare over crusty snow, which gives the cats the advantage, while others chase their quarry over fluffy snow, which gives the hares the advantage. Rising temperatures will result in fluffy snow turning crusty in some regions, thereby increasing the hunting success of lynx -- and influencing the cycle in ways that might have a negative impact on both animals, he says.
Boutin calls this "one more way in which global warming is giving us an ecological warning.
