Vegetation and climate across the EarlyeMiddle Pleistocene transition at Montalbano Jonico, southern Italy
Pollen analysis of the Montalbano Jonico marine succession (MJS), southern Italy, provides a continuous vegetational record between 858 ka and 745.13 ka which includes Marine Isotope Stage (MIS) 19, now considered the closest orbital analogue to the Holocene. A comparison between paleoclimate proxie...

Pollen analysis of the Montalbano Jonico marine succession (MJS), southern Italy, provides a continuous vegetational record between 858 ka and 745.13 ka which includes Marine Isotope Stage (MIS) 19, now considered the closest orbital analogue to the Holocene. A comparison between paleoclimate proxies and global signals of past climate change allows the pollen record to be interpreted in terms of major environmental and climate modifications through MIS 21e18 at the orbital- and sub-orbital-scale. This is also central to understanding migration patterns of the genus Homo. Interglacials are expressed by the dominance of a mesophilic vegetation typical of a (warm) temperate and relatively humid climate.
