  abstract = {{F}ruit abscission facilitates the optimal conditions and timing of seed dispersal. {E}nvironmental regulation of tropical fruit abscission has received little attention, even though climate change may have its strongest impacts in tropical regions. {I}n this study, oil palm fruit abscission was monitored during multiple years in the {B}enin {R}epublic to take advantage of the climatic seasonality and the continuous fruit production by this species. {A}n innovative multivariable statistical method was used to identify the best predictors of fruit abscission among a set of climate and ecophysiological variables, and the stage of inflorescence and fruit bunch development when the variables are perceived. {T}he effects of climate scenarios on fruit abscission were then predicted based on the calibrated model. {W}e found complex regulation takes place at specific stages of inflorescence and bunch development, even long before the fruit abscission zone is competent to execute abscission. {A}mong the predictors selected, temperature variations during inflorescence and fruit bunch development are major determinants of the fruit abscission process. {F}urthermore, the timing of ripe fruit drop is determined by temperature in combination with the trophic status. {F}inally, climate simulations revealed that the abscission process is robust and is more affected by seasonal variations than by extreme scenarios. {O}ur investigations highlighted the central function of the abscission zone as the sensor of environmental signals during reproductive development. {C}oupling ecophysiological and statistical modeling was an efficient approach to disentangle this complex environmental regulation.},
