Habitat filtering and interspecific competition influence phenological diversity in an assemblage of Neotropical savanna grasses

摘要: Phenology in plants is closely related to the environmental features of their habitats, which can act as habitat filtering, clustering species with particular adaptations. On other hand, aggregation lead competition between them, segregating niches. We investigated if filtering and interspecific influence phenological diversity an assemblage grass savanna grasslands central Brazil. conducted observations, 15-day intervals, ten grasses. used circular statistics ascertain seasonality phenology null models estimate overlap species. The reproductive period grasses was seasonal concentrated rainy season, corroborating hypothesis; however, within niche less than expected at random. Flowering more segregated fruiting seed dispersal. Although have similar architectural feature share above underground niche, these results suggest that are under pressure this result segregation, allowing coexistence them.
