摘要: Pollen analysis of the Early Pleistocene Montalbano Jonico section in southern Italy reveals cyclic changes driven by climate and eustasy, as illustrated mesothermic vs. steppe elements for climate, Pinus Caryophyllaceae, Amaranthaceae–Chenopodiaceae Ephedra eustasy. These results are directly compared with oxygen isotope data on Globigerina bulloides constrained within a biostratigraphic framework based nannofossils foraminifers, facilitating new age calibration section. Marine isotopic stages 37 to 23 (1.250–0.900 Ma) recorded, global Mediterranean curves. High-frequency pollen related curve (Globigerinoides ruber) from ODP Site 967, superimposed LR04 stack curve. During Pleistocene, recorded regional obliquity precession, respectively, tectonic evolution. Precession forcing was caused wetness precession. The intensified precession effect over climatic cycles, that is expected during Middle Transition, not interval A vegetation changes.
