Responses in the diet composition of the Common frog (Rana temporaria) to the stochastic gradation of Autumnal moth (Epirrita autumnata) larvae
We studied the feeding ecology of the common frog Rana temporaria in a population located at the subarctic taiga-tundra frontier in Finland over two consecutive years (2002, 2003). In the summer of 2003, an unexpected gradation of autumnal moth (Epirrita autumnata) larvae occurred at our study site....
