             abstract = "Caatinga is a typical biome of Brazils semiarid regions and 
                         subject to climate changes. Research is needed on the relation of 
                         its features to climate events. This study analyzed the influence 
                         of rainfall and its irregularities in open and dense woody 
                         Caatinga vegetation. Phenological curves were generated by means 
                         of Normalized Difference Vegetation Index (NDVI) time profiles in 
                         the Grota do Angico Conservation Unit study area in Sergipe State. 
                         Rainfall data from 2000 to 2018 were collected and phenological 
                         curves generated using various estimate methods that produced the 
                         following variables: [start of season, end of season, peak of 
                         season position, length of season, mean growing season and maximum 
                         seasonal]. Rainfall showed a standard intra-annual behavior, with 
                         inter-annual variations related to irregularities influencing 
                         Caatinga response. Dense Caatinga vegetation had higher values of 
                         NDVI in all periods, even in anomalous years compared to open 
                         Caatinga, in addition to having longer leaf coverage over the 
                         year, with an anticipated start and a more extended seasonal end. 
                         The analysis of the rainfall regime made it possible to assess its 
                         influence on the Caatinga and phenological profiles proved to be 
                         fundamental to understand periods of physiological change of open 
                         and dense Caatinga. These results indicate that dense Caatinga 
                         maintains physiological activity longer, which may be associated 
                         with greater moisture maintenance in a semiarid region. In 
                         addition, because it has a greater leaf cover for longer periods, 
                         the soil may be preserved and maintain its characteristics longer, 
                         reducing the effects of desertification. The results may be 
                         associated with the type of forest management and conservation in 
                         this region. The total or partial suppression of individual 
                         remnants of Caatinga should be avoided, since the most open areas 
                         have lower photosynthetic capacity, affected to a considerable 
                         extent from the effects of adverse climatic conditions. 
                         Additionally, open Caatinga has a reduced capacity for 
                         regenerating naturally and its use by communities in this semiarid 
                         region should be limited.",
