An analysis of rates of ecological change (RoC) from thirteen pollen records from tropical South America is presented here. The analysis aims to identify the periods of fastest change since the last glacial maximum (LGM) and possible driving mechanisms. Despite rapid cooling periods, region-wide profound droughts, fire and human disturbances, RoC analysis showed that the speed of these climate changes never exceed the species response capabilities. Our results legitimize concerns regarding the
