Resumen

The dispersal of hominins may have been favored by the opening of the landscape during the EarlyeMiddle
Pleistocene transition (EMP) in Western Europe. The structure of the small-vertebrate
assemblages of the archaeo-paleontological karstic site of Gran Dolina in Atapuerca (Burgos, Spain)
shows important environmental and climatic changes in the faunal succession, across the MatuyamaeBrunhes
boundary at 780 ka. These changes are interpreted to indicate impoverishment of the
forests, along with an increase in dry meadows, and open lands in general that entailed a tendency
towards the loss of diversity in small-vertebrate communities above the EMP. We evaluate variation in
diversity of the faunal succession of Gran Dolina using Shannon’s Second Theorem as an index of
ecosystem structure. The long cultural-stratigraphic sequence of Gran Dolina during the EMP is somewhat
similar in its completeness and continuity to that in the locality of Gesher Benot Ya'aqov in the
Upper Jordan Valley. We also evaluate related data including faunal and floral (pollen) succession. Both
localities present cold, dry and humid, warm fluctuations at the transition between the Early and the
Middle Pleistocene. Comparisons between these sites present opportunities to understand large-scale
climatic changes.
