•Germination temperature thresholds are related to moisture in the microhabitats.•ABA mediates interactions between light and temperature to germinate.•Most species from campo rupestre can form long-term persistent soil seed banks.•Cyclical dormancy is highly synchronized with the soil moisture seas...
