Wetlands are ecosystems at the interface between terrestrial and aquatic environments, subject to flooding by shallow waters or with temporarily to permanently waterlogged soils and specialized biota. Despite their great importance at global and local scales, these ecosystems have not been effectively protected in Brazil. The Cerrado wetlands are p...

Pollen grains can provide valuable information to forensic palynology, such as the time of death or the possible origin of a corpse. Forensic Palynology is a vital tool to be used in a criminal investigation because the different environment has distinct pollen signatures. Brazil has a rich and diversified flora that is suitable for the application...

Chapter
Monodominance is defined as a phenomenon whereby a single species can cover most of the terrain in comparison with other species. In tropical environments, monodominance can be considered as an odd phenomenon because of the high species diversity that is normally found in a single hectare. In the tropics, this phenomenon is more common in floodable...
