“…We have previously argued (Fortelius et al, , 2003 that the climatic changes suggested by the hypsodonty maps are in agreement with general predictions from palaeoclimate models and palaeoclimatic proxy data from both the marine and the continental realm (e.g., Prell and Kutzbach, 1992;Kutzbach et al, 1993;Broccoli and Manabe, 1997;Ruddiman, 1997;An et al, 2001), especially in the late Miocene aridification of Asia north and west of the Tibetan Plateau and the relative lack of change to the east and south of the Plateau. Of particular interest in the continental-scale sequence is the return to more humid conditions in northern China in the latest Miocene, coinciding in time with evidence of strengthened monsoon circulation at about 8 Ma (Molnar et al, 1993;Rea et al, 1998;Griffin, 1999).…”

“…During the Cretaceous, the Korean peninsula area was situated inland (Choi, 1985;Matsukawa et al, 1995;Chough et al, 2000) in mid-latitudes as it is today (Lee et al, 1987;Kim et al, 1993). The arid climatic conditions during the Late Cretaceous in the Korean peninsula are thus compared to that of modern mid-latitudes due to an orographic effect (Critchfield, 1983;Broccoli and Manabe, 1997).…”

“…The uplift of mountains and plateaus affects climate because it changes patterns of precipitation and seasonal heating, creates a barrier to atmospheric circulation, affects upper atmosphere flow patterns, and may increase rates of chemical weathering (Ruddiman and Kutzbach, 1989;Raymo and Ruddiman, 1992;Hay, 1996;Broccoli and Manabe, 1997). In order to understand how climatic changes affect the biota, it is important to study the elevational history of uplifted regions.…”

An assemblage of 33 fossil pollen and spores, recovered from the 3600‐m high Pislepampa locality of E. W. Berry, Eastern Cordillera, Bolivia, adds considerably to our knowledge of three aspects of the region in late Neogene time: (1) the paleovegetation, (2) the paleoclimate, and (3) the paleoelevation of the Central Andes. The plant microfossils recognized are Isoetes, Lycopodium (three types), Cnemidaria, Cyathea (three types), Grammitis, Hymenophyllum, Pteris, trilete fern spores (two types), Danaea, monolete fern spores (four types), Podocarpus, Gramineae, Palmae, Ilex, cf. Oreopanax, Cavanillesia, cf. Pereskia, Compositae (three types), Ericaceae, Tetrorchidium, and unknowns (three types). The diversity of the Compositae suggest that this flora has a maximum age around the Miocene‐Pliocene boundary, that is, 6–7 million years. All members of the paleocommunity presently grow in the bosque montano húmedo (cloud forest) along the eastern slope of the Central Andes of Bolivia, which occurs between MATs (mean annual temperatures) of ∼10° and 20°C. The Pislepampa flora probably represents the lower limits of this forest because the fossil leaves collected by Berry from the same locality all have entire margins, suggesting that the flora grew near the cloud forest–tropical forest transition. Presently, the lower limit of the cloud forest forest has MATs of ∼20°C, a mean annual precipitation between 1000 and 1500 mm, and that part containing most of the identified genera of fossil pollen is found at elevations ∼1200–1400 m. These conditions are thus inferred for the Pislepampa flora; however, because of the uncertainty of the magnitude of global climate change and of possible changes in the ecological range of plant genera, we estimate an error of at least ±1000 m for the paleoelevation estimate. When the total uplift is corrected for probable amounts of erosionally driven isostatic rebound, the paleoelevation estimate suggests that from one‐third to one‐half of the uplift of the Eastern Cordillera had occurred by the beginning of the Pliocene. This estimate is consistent with other paleoelevation estimates from the Central Andes.
