Samantha P. Klaus and Stephen C. Lougheed Changes in breeding phenology of eastern Ontario frogs over four decades Ecology and Evolution 3
Our study examines how long-term changes in local temperatures and precipitation have affected the timing of emergence and the onset of calling activity in Ontario frog species. In two of eight observed species, breeding phenology has shifted over four decades, correlating with local increases in spring temperatures and a literature review revealed regional differences in phenological shifts within and among species. These can have significant impacts on how we understand the consequences of climate change on range limits and species and population persistence, and how we might predict future trends.
