More research needed on effects of maternal stress in wild animals

If a human mother is stressed while pregnant, research shows her child is much more likely to have emotional, cognitive or even physiological problems, such as attention deficit, hyperactivity, anxiety, language delay, obesity, diabetes and hypertension. Conversely, the results of maternal stress on the offspring of other animals—particularly wildlife under threat from predators—is believed to be positive, and contributes to their survival.
