abstract = {Glacial Termination V (T-V) comprised a relatively rapid shift from glacial to interglacial conditions (MIS 12
glacial to the MIS 11c); it was one of the greatest climatic changes of the Pleistocene, and forms part of the major
climatic reorganization known as the Mid-Brunhes Event (MBE). The Fucino Basin, located in the Central
Apennine chain of central Italy, contains a continuous and well-preserved lacustrine sedimentary record of T-V
and MIS 11, dated using tephrochronology. In this paper, we report a high-resolution palynological analysis,
supported by geochemical proxies, from the lowermost section of the F4-F5 composite record, to improve understanding
of T-V in this region. This record reveals a substantial transition between MIS 12 and MIS 11c at
424.5 ± 4.0 ka, from a very cold and dry environment indicated by the herbaceous and xerophytic association of
Poaceae, Artemisia, Amaranthaceae, Ephedra, and Hippoph¨ae, and sedimentation dominated by inorganic siliciclastic
sediments, to a warm and humid period characterised by a significant increase in Abies and a deciduous
tree association mainly formed by Betula, Carpinus, Corylus, Quercus, Ulmus, and dominated by more organic
calcareous sediments. This transition was correlated with a significant lake-level rise, with an enhanced nutrient
input into the lake between 425.0 ± 4.5 ka and 424.0 ± 3.9 ka, as inferred from the variance between algae,
aquatic plants, and terrestrial herbaceous taxa. Following the MIS 11c temperature maximum at 424.2 ± 3.9 ka,
a reduction in summer insolation occurred, provoking a significant increase in humidity that produced the
widespread development of Abies. The results from this study suggest that, at Fucino, fluctuations in humidity are
predominantly responsible for the vegetation changes observed during T-V.},
