Asian black bears' smart strategy for seasonal energy balance

(Tokyo University of Agriculture and Technology) A collaboration led by scientists at Tokyo University of Agriculture and Technology (TUAT), Japan, has discovered that daily energy balance of Asian black bears exhibited seasonal change with a twin-peak pattern: up in spring, down to the lowest point in summer, and up again in autumn. From spring to summer, the energy balance is surprisingly negative. Interestingly, bears obtain about 80% of the energy they need in a year by eating acorns in autu...
