The term beta diversity has been used to refer to a wide variety of phenomena. Although all
of these encompass some kind of compositional heterogeneity between places, many are …

A vast literature indicates that environment plays a paramount role in determining floristic
composition in tropical forests. However, it remains unclear which are the most important …

The pteridophytes present a great but poorly explored potential as ecological indicators
(EIs), shown only in some sparse studies. Therefore, to analyze this potential, we reviewed …

Aim Conservation and land‐use planning require accurate maps of patterns in species
composition and an understanding of the factors that control them. Substantial doubt exists …

Aim To map and interpret floristic and geoecological patterns across the Amazon basin by
combining extensive field data with basin‐wide Landsat imagery and climatic data. Location …

Many recent studies have quantified the relative importance of environmental variables and
dispersal limitations in shaping the structure of stream communities. However, the relative …

Aim To provide a global assessment of turnover in vascular plants across geographical
settings and taxonomic and functional groups. We tested whether turnover and its spatial …

The number of species is known to decrease from the humid tropics towards drier and colder
climates, but how species richness varies along environmental and spatial gradients within …

Aim Our goal was to test the hypothesis that ancient humans substantially contributed to
shaping the current distribution of Brazil nut (Bertholletia excelsa), an Amazonian tree …

In northern South America the Cenozoic was a period of intense tectonic and climatic
interaction that resulted in a dynamic Amazonian landscape dominated by lowlands with …
