Currently, several concerns have been raised over metal contamination in the upper
Amazon basin. Rivers that flow from the high Andes to the lowland Amazon are threatened …

Tropical montane forests (TMF) are characterised by high endemism, species richness and
turnover across elevations. A key question is how niche‐based processes, via adaptation of …

A conspicuous feature of natural communities is that individuals within species exhibit broad
variation in their phenotype. While the phenotypic differences among species are prominent …

As a transitional vegetation type between evergreen broadleaved forest and deciduous
broadleaved forest, evergreen-deciduous broadleaved mixed forest is composed of diverse …

Aim Ecological niches shape species commonness and rarity, yet, the relative importance of
different niche mechanisms within and across ecosystems remains unresolved. We tested …

The ecotonal zones support populations that are acclimated to changing, fluctuating, and
unstable conditions, and as a result, these populations are better equipped to adjust to …

Land‐use and management are disturbance factors that have diverse effects on community
composition and structure. In traditional rural grasslands, such as meadows and pastures …

Many theories have been proposed to explain the high diversity of plants in the tropics.
However, we lack an understanding of the processes that drive plant diversity and …

The decline in species richness at higher latitudes is among the most fundamental patterns
in ecology. Whether changes in species composition across space (beta-diversity) …

The Amazon forest covers 7.5 million km2 in nine countries, hosts 25% of the global
biodiversity and is a major contributor to the biogeochemical and climatic functioning of the …
