We compared flowering times predicted by six possible proximate cues involving seasonal changes in rainfall and irradiance and flowering times observed over 30 years of weekly censuses for 19 tree and liana species from Barro Colorado Island (BCI), Panama. Hypotheses concerning variation in the timi...
