The study was conducted in an area of caatinga in Pernambuco State. and sought to test whether the dynamics of Croton blanchetianus could be correlated with the variation in precipitation between seasons and between years. All individuals of C. blanchetianus present in the sampled plots were monitored monthly for two consecutive new seedlings of C. blanchetianus between seasons and between years. Considering the variation in rainfall between consecutive years, population seem to have being little influenced, as the generalized linear model (GLM) showed that only 14.8% of new seedlings in this population can be explained by the variation of precipitation between seasons and between years. In the case of deaths, the explanatory power is 1.4%, considering the interaction between seasonal and interannual variation in rainfall. So, a broader approach from an ecological point of view is necessary to evaluate environmental factors that are decisive, and that could influence the renovation rhythm of this population in time.Downloads
