Contrasting responses of two Caribbean mangroves to sea-level rise in the Guajira Peninsula (Colombian Caribbean)

► Sea-level rise was not uniform in the Colombian Caribbean during the Holocene. ► Rapid sea-level rise and lagoon formation were recorded during early Holocene. ► Mid-Holocene stabilized sea levels and high precipitation allowed mangroves to expand. ► Avicennia dominance and a regional drought were recorded between 2850 and 2450 BP. ► Current marine transgression is causing both mangrove diminution and expansion.
