Background: The Atlantic Forest biome is a top hotspot for conservation priorities, but the variations in fern species composition and the factors driving these are still poorly known. The vegetation gradient found in the state of Santa Catarina, southern Brazil, constitutes an interesting environmental model for examining such patterns. Aims: We...
Article
The conversion of native forests into pastures is still a common practice in Brazil. Abandoned pastures have great potential for natural regeneration and therefore could play an important role in meeting the enormous demand for forest restoration. Few studies, however, have investigated the extent to which spatially-structured environmental variabl...

The latitudinal diversity gradient (LDG) is one of the most recognized global patterns of species richness exhibited across a wide range of taxa. Numerous hypotheses have been proposed in the past two centuries to explain LDG, but rigorous tests of the drivers of LDGs have been limited by a lack of high-quality global species richness data. Here we...

Background - The fast-slow plant economy hypothesis predicts strong co-variation in key resource-use traits due to the trade-off between growth and survival of species. Accordingly, it is expected that trait variation may be reduced to a single dimension along a growth-survival gradient. However, some studies warn against such reductionism and prom...
Article
Secondary forests play an important role as landscape elements, providing carbon uptake, biodiversity recovery, and income for rural communities. We aimed to present change estimates for three forest types in the subtropical Atlantic Forest, namely evergreen rainforest (ERF), Araucaria forest (AF), and semi-deciduous forest (SF). We used data gathe...
