This selective review of the Quaternary paleoclimate of the South American summer
monsoon (SASM) domain presents viewpoints regarding a range of key issues in the field …

The neotropical Amazonian and Andean plant diversity developed mainly during the
Tertiary. In Amazonia, Miocene floral diversity seems considerably higher than today. During …

Amazonian rain forest–savanna boundaries are highly sensitive to climatic change and may
also play an important role in rain forest speciation. However, their dynamics over millennial …

Late Quaternary paleoenvironments from northeastern (NE) Brazil have been studied by
pollen analysis of marine sediment. The studied core GeoB 3104-1 (3° 40′ S, 37° 43′ W …

Fossil rodent middens and wetland deposits from the central Atacama Desert (22° to 24° S)
indicate increasing summer precipitation, grass cover, and groundwater levels from 16.2 to …

Palaeoecological data recording a pronounced environmental shift centred about 4000
years BP are presented from tropical Africa and South America. The environmental shift is …

Although many of the current hypotheses to explain the origin and distribution of the Amazon
biodiversity has been based directly or indirectly on geological data, the reconstruction of …

The hyperarid core of the Atacama Desert possesses important reserves of “fossil” or ancient
groundwater, yet the extent and timing of past hydrologic change during the late Quaternary …

An improved understanding of present-day climate variability and change relies on high-
quality data sets from the past 2 millennia. Global efforts to model regional climate modes …

Plant macrofossils, percentage abundance of grass taxa, fecal-pellet δ13C, and plant-cuticle
contents from 49 fossil rodent middens dated by 14C record changes in local vegetation and …
