Global warming has shifted frog calling seasons earlier by ten to thirteen days

Evidence

For instance, the calling phenology of frogs has been documented to be changed during the past century, as reported by Gibb and Breisch (2000) near Ithaca, New York. Four species of frogs have been observed to be calling 10–13 days earlier than in the period 1900–1912. Two species have unchanged phenology, but none of the species is calling later in the season. This observation indicates that the global warming has produced biological responses in these populations (Table 2.1). — Almo Farina, Soundscape Ecology, 294
