AB Spatial and temporal variations in fruit fall are critical in the structuring of plant populationsand are important determinants of canopy composition. We analyzed fruit fall intwo laurel forests, near Tenerife, Canary Islands, during one year to quantify temporal variationin fruit abundance and its relationship with canopy composition. There was sometemporal synchrony among fruiting tree species in fruit fall phenology at the two study forests.Although the canopy composition of both sites differed significantly, the fruit fallcomposition did not show significant differences. In spite of that, some species showed differencesin abundance between sites, with a greater biomass of Laurus azorica, Ilex peradoand Myrica faya at Aguirre than at El Moquinal site. The temporal variation on fruit fallcomposition was low and it was not possible to infer seasonality in these laurel forestson the basis of fruit fall composition. The analysis revealed significant differences amongsites, but not between species.Our results suggest a potentially important role of frugivores (together with some differencesamong sites in forest structure) in the spatial fruit pattern. However, temporal patternsare not as clear and only two species showed synchrony in fruit production, whichwe related with an attenuated seasonality as can be extracted from the lack of differencesin fruit production along the different seasons.
