Plants respond to Pleistocene climatic change as species, not as associations or biomes.
This has been demonstrated unequivocally by paleobotanical data for temperate latitudes …

Palynological studies of a peat-bog sequence, with a basal date of 10,990±80 yr BP, provide
a history of vegetational and climatic changes in the Icatu River Valley located inside a large …

Durante algum tempo, também entre herpetólogos, prevaleceu a idéia de que a Caatinga
não tinha fauna própria (Vanzolini 1974, 1976, 1988, Mares et al. 1981). Admitia-se que os …

The Brazilian Caatinga is considered the richest nucleus of the Seasonally Dry Tropical
Forests (SDTF) in the Neotropics, also exhibiting high levels of endemism, but the timing of …

The modern Amazon lowlands date from the mid-Cenozoic, when the Andean orogeny
defined an eastward, or northward draining basin of immense size. As the Andean orogeny …

The concept of tectonic stability has long prevailed for most of the Brazilian platform and,
because of this fact, investigation of Quaternary tectonics in Brazil has begun to develop …

The Neotropics harbors a high diversity of species and several hypotheses have been
proposed to account for this pattern. However, while species of forested domains are …

One dune habitat in the semi-arid Caatinga Biome, rich in endemisms, is described based
on plant species composition, woody plant density, mean height and phenology and a …

In the backlands of the easternmost corner of South America, where the continent forms a
large convex bulge projected into the South Atlantic, in latitudes ranging from 2° to 16° south …

Our interpretation of the available palynological data from the Amazon basin is that they
show a long history of continuous occupation by forest. We have thoroughly reviewed the …
