Abstract: The relationship between phenology and environmental factors is critical to understanding population dynamics in environmental gradients. We evaluated phenological variations in Croton heliotropiifolius Kunth in sites with contrasting water resource availability in caatinga, cerrado/caatinga transition, and cerrado in the Chapada Diamantina, Brazil. The phenophases of 81 individuals (n = 27 individuals/area) were recorded monthly for 12 months. Multiple regression, Spearman correlation, circular statistics, Sh… Show more

“…Additionally, environmental (precipitation and temperature) and plant variables (PlantH and TrunkH) were found to affect the reproductive phenology of the species, and consequently its seed production potential. Studies concerning variations in phenological behavior within and among woody plant populations and their habitats can help to better understand their spatio-temporal variations as survival strategies in different environments (Goulart et al, 2005;Santos et al, 2020;Costa et al, 2021) and aid in elucidating how local abiotic factors and plant traits influence phenological patterns (Moraes et al, 2017;Neves et al, 2017;Santos et al, 2021).…”

“…ao avaliar padrões fenológicos de fisiológica das sementes, pelo reduzido teor de água e fornecendo alimentos à fauna no período crítico, consequentemente ampliando suas possibilidades de interação com os animais dispersores.Em pesquisa realizada em área de Caatinga e de transição Cerrado/Caatinga,Costa et al (2021) encontraram sazonalidade nas fenofases de Croton heliotropiifolius, com a produção de flores durante a estação chuvosa.foram distintos para as populações observadas, possivelmente por variações microambientais, disponibilidade hídrica e interações entre polinizadores e dispersores de sementes. Tais achados corroboram com as conclusõesde Costa et al (2021) sobre a hipótese de influência do habitat para explanar as diferenças de padrões reprodutivos entre populações. Através de métodos estatística circular, foi possível detectar a sazonalidade dos eventos.Conforme Pinto et al (2021), a temperatura e o fotoperíodo foram os gatilhos para desencadear as fenofases reprodutivas, o que é corroborado por Bauer et al (2014).…”
