Impacts of increasing typhoons on the structure and function of a subtropical forest: reflections of a changing climate

Abstract Due to their destructive and sporadic nature, it is often difficult to evaluate and predict the effects of typhoon on forest ecosystem patterns and processes. We used a 21-yr record of litterfall rates to explore the influence of typhoon frequency and intensity, along with other meteorologi...
