Do conspecific populations exhibit divergent phenological patterns? A study case of widespread savanna species

摘要

Highlights?The duration of the dry period may affect phenological strategies in plants.?We studied this effect in five savanna woody species at Northeastern Brazil.?Phenology was mostly related to air temperature and day length during dry season.?Phenological responses were delayed at the longer dry season site.?Phenological peaks in conspecific populations differ under different climates.AbstractWidespread savanna tree species can grow and survive at sites that diverge in water availability and seasonality, thus these species may be able to adjust their phenology in response to site variations. Here we evaluated vegetative and reproductive phenology in five woody species whose populations grow at two savannas sites under divergent climatic regimes, inserted in a large transitional zone between
