abstract = "The Last Glacial Maximum (LGM, 26.519 ka) was marked by
atmospheric cooling, in contrast to the current warming climate,
which will probably continue in the coming decades, according to
climate models projections. The LGM to pre-industrial transition
provides an opportunity to test the vegetation response to a very
large temperature change that can then be applied to project
pre-industrial to end-of-century changes. In order to explore the
changes in Brazilian biomes due to temperature change, we
projected potential vegetation for both past and future scenarios.
We compared biome projections with a compilation of 149 published
LGM reconstructions of climate and vegetation within Brazil and
adjacent areas. In addition, we evaluated the particular effects
that changes in precipitation, temperature and CO2 had on
vegetation by performing sensitivity experiments. Our results
suggest that biomes in the western and central portions of the
Amazon forest remained largely unchanged during the LGM mainly due
to negative temperature anomalies, while a decrease in past
precipitation was responsible for the shift from tropical
evergreen forest to tropical seasonal forest in the eastern
portion of the Amazon. These results are consistent with proxy
reconstructions. LGM model projections and proxy reconstructions
suggest expansion of grassland in the southern Brazilian
highlands. Under future warming scenarios, biome changes are
mostly forced by decreasing precipitation and increasing
temperatures, which counteract potential biomass gain from the
positive CO2 fertilization effect. Under future warming, our
simulations show an expansion of Savanna/Cerrado and a reduction
of tropical seasonal forest and Caatinga, with potential large
impacts over biodiversity and regional climate.",
