Edge effects are major drivers of change in many fragmented landscapes, but are often highly variable in space and time. Here we assess variability in edge effects altering Amazon forest dynamics, plant community composition, invading species, and ca

Foram estudadas mudanças nos parâmetros bioquímicos do solo em resultado da derruba e queima da floresta tropical na Amazônia brasileira para o estabelecimento de pastagens através da biomassa microbiana, um sensível indicador de modificações

Little attention has been paid to plant mutualistic interactions in the Amazon rainforest, and the general pattern of occurrence and diversity of arbuscular mycorrhizal fungi (AMF) in these ecosystems is largely unknown. This study investigated AMF c

We synthesize findings to date from the world’s largest and longest-running experimental study of habitat fragmentation, located in central Amazonia. Over the past 32 years, Amazonian forest fragments ranging from 1 to 100 ha have experienced a wid

Question: How do soils and topography influence Amazonian tree diversity, a region with generally nutrient-starved soils but some of the biologically richest tree communities on Earth? Location: Central Amazonia, near Manaus, Brazil. Methods: We eval

We summarize a long-term study of the effects of edge creation on establishment of the economically important arboreal palm Oenocarpus bacaba in an experimentally fragmented landscape in central Amazonia. Recruitment and mortality of large individual

Fungi are important components of tropical ecosystems, especially in the recycling of nutrients. However, there is little information on how fungal diversity is structured at scales suitable to plan their conservation. We tested if the distribution o

Experiments were carried out to test the effects of liming and nutrient additions on plant growth and soil processes such as C and N mineralisation in three contrasting forest types in central Amazonia: the stunted facies of heath forest (SHF), the t

We tested the hypothesis that the growth of fine roots upward into the leaf litter, forming a ‘surface root mat’, found widely in Amazonian forests, is of adaptive value for plants of poor soils because it makes possible more rapid uptake of limi

We used forest inventories, conducted in seventy-two 1-ha permanent plots to assess the variation in tree and palm aboveground live biomass (AGLB), and its relation with soil gradients (texture and nutrients) and topography (altitude and slope). Our
