Flood tolerance in two tree species that inhabit both the Amazonian floodplain and the...

Comparing plants of the same species thriving in flooded and non-flooded ecosystems can help to clarify the interplay between natural selection, plant plasticity and...
Savanna fire, an increasingly rare sight in parts of the Cerrado.

Expanding forests can be bad news for the environment

You might think that increasing forest cover is good news in Brazil, but that’s not always the case, according to a new study.
Schematic representation the demographic history scenarios simulated for the 23 populations of Eugenia dysenterica sampled in the Cerrado biome, and their geographical representation as predicted by ecological niche models (ENMs

Origin of distribution and genetic diversity of a savanna species

Cyclic glaciations were frequent throughout the Quaternary and this affected species distribution and population differentiation worldwide. Combining ecological niche modelling and phylogeographical analysis, this study...

Historical refugia and origins of genetic diversity in a Neotropical savanna tree species

Souza et al. investigate the role of Pleistocene climate changes in driving the geographic distribution and genetic diversity of Dimorphandra mollis, a tree species...
Predicted regions of historical stability in the Phylocallyx clade across the Quaternary

Climate change refugia and species diversity in Eugenia

Eugenia is the most species-rich Neotropical genus. This ‘Research in Context’ article explores the extraordinary evolutionary success of Eugenia sect. Phyllocalyx using a phylogenetic...
Endogenous hormones and fructan metabolism in Chrysolaena

Endogenous hormones and fructan metabolism in Chrysolaena

Results suggest that the co-ordinated action of carbohydrate metabolism and hormone synthesis enables C. obovata to survive unfavourable field conditions.
Chrysolaena obovata

Co-ordinated carbohydrate metabolism and hormone synthesis enables plants to survive unfavourable field conditions

Chrysolaena obovata, an aster of the Brazilian Cerrado, presents seasonal growth, marked by senescence of aerial organs in winter and subsequent regrowth at the...
Utricularia menziesii

Can conservation kill?

Normally when someone asks a dramatic question in a headline the answer is no. This time though it's different. A paper in the new...
