Geometrid outbreak waves travel across Europe
1.We show that the population ecology of the 9- to 10-year cyclic, broadleaf-defoliating winter moth (Operophtera brumata) and other early-season geometrids cannot be fully understood on a local scale unless population behaviour is known on a European scale. 2.Qualitative and quantitative data on O....
