The intertwined population biology of two Amazonian myrmecophytes and their symbiotic ants
ant–plant interactions Cordia nodosa demography
2015/12/10
A major question in ecology is: how do mutualisms between species affect
population dynamics? For four years, we monitored populations of two Amazonian
myrmecophytes, Cordia nodosa and Duroia hirsut...
Analysing Amazonian forest productivity using a new individual and trait-based model (TFS v.1)
Amazonian forest productivity new individual trait-based model
2014/12/19
Repeated long-term censuses have revealed large-scale spatial patterns in Amazon basin forest structure and dynamism, with some forests in the west of the basin having up to a twice as high rate of ab...
THE 2005 AND 2010 AMAZONIAN DROUGHTS AS SEEN BY MODIS
THE 2005 2010 AMAZONIAN DROUGHTS SEEN BY MODIS
2014/5/6
During this decade, the Amazon region in South America has suffered two severe droughts in the short span of five years ––2005 and 2010. The 2005 drought, dubbed a once-in-a-century drought, has been ...
Hygroscopic properties of Amazonian biomass burning and European background HULIS and investigation of their effects on surface tension with two models linking H-TDMA to CCNC data
Hygroscopic properties H-TDMA CCNC data surface tension
2010/8/13
HUmic-LIke Substances (HULIS) have been identified as major contributors to the organic carbon in atmospheric aerosol. The term "HULIS" is used to describe the organic material found in aerosol partic...
Above- and below-ground net primary productivity across ten Amazonian forests on contrasting soils
Above- and below-ground net primary productivity ten Amazonian forests contrasting soils
2010/1/21
The net primary productivity (NPP) of tropical forests is one of the most important and least quantified components of the global carbon cycle. Most relevant studies have focused particularly on the q...
Multi-scale comparisons of tree composition in Amazonian terra firme forests
Multi-scale comparisons tree composition Amazonian terra firme forests
2010/1/21
We explored the floristic composition of terra firme forests across Amazonia using 55 plots. Firstly, we examined the floristic patterns using both genus- and species-level data and found that the spe...
Basin-wide variations in foliar properties of Amazonian forest:phylogeny,soils and climate
Basin-wide variations foliar properties Amazonian forest phylogeny soils climate
2010/1/21
We analysed 1040 individual trees, located in 62 plots across the Amazon Basin for leaf mass per unit area (MA), foliar carbon isotopic composition (δ13C) and leaf level concentrations of C, N, P, Ca,...
Spatial trends in leaf size of Amazonian rainforest trees
Spatial trends leaf size Amazonian rainforest trees
2010/1/20
Leaf size influences many aspects of tree function such as rates of transpiration and photosynthesis and, consequently, often varies in a predictable way in response to environmental gradients. The re...
Spatial distribution and functional significance of leaf lamina shape in Amazonian forest trees
Spatial distribution functional significance leaf lamina shape Amazonian forest trees
2010/1/20
Leaves in tropical forests come in an enormous variety of sizes and shapes, each of which can be ultimately viewed as an adaptation to the complex problem of optimising the capture of light for photos...
A comparative study of the soil solution chemistry of two Amazonian forest soils (Central Amazonia, Brazil)
soil water chemical composition forest soils
2009/6/8
Analyses of the chemical composition of rapidly percolating soil water were used to study the genesis of a shallow podzol in a Campinarana forest and a clayey ferralsol from a typical rainforest loca...
Carbon dioxide measurements in the nocturnal boundary layer over Amazonian forest
dioxide measurements nocturnal boundary
2009/3/25
Measurements of carbon dioxide concentration, temperature and windspeed were made in the nocturnal boundary layer over a tropical forest near Manaus, Brazil using a tethered balloon system.
Do species traits determine patterns of wood production in Amazonian forests?
species traits determine patterns wood production Amazonian forests
2010/1/19
Understanding the relationships between plant traits and ecosystem properties at large spatial scales is important for predicting how compositional change will affect carbon cycling in tropical forest...
Single particle analysis of the accumulation mode aerosol over the northeast Amazonian tropical rain forest, Surinam, South America
accumulation mode aerosol northeast Amazonian tropical rain forest Surinam South America
2009/2/19
Single particle analysis of aerosols particles larger than 0.2 μm diameter was performed on 24 samples collected over Surinam tropical rain forest and in the adjacent marine boundary layer (MBL) durin...
Spatial and temporal distribution of atmospheric aerosols in the lowermost troposphere over the Amazonian tropical rainforest

2009/2/11
We present measurements of aerosol physico-chemical properties below 5 km altitude over the tropical rain forest and the marine boundary layer (MBL) obtained during the LBA-CLAIRE 1998 project. The MB...
Isoprene and monoterpene fluxes from Central Amazonian rainforest inferred from tower-based and airborne measurements, and implications on the atmospheric chemistry and the local carbon budget
