Recent studies show widespread encroachment of forest into savannas with important consequences for the global carbon cycle and land-atmosphere interactions. However, little research has focused on in situ measurements of forest-savanna boundary change over time. Using long-term inventory plots we quantify changes in above-ground biomass (AGB), vegetation structure and biodiversity over 20 years for five vegetation types (savanna, colonising forest or F1, successional monodominant forest or F2, Marantaceae forest or F3 and mixed forest or...
Atmospheric CO2 records indicate that the land surface has acted as a strong global carbon sink over recent decades, with a substantial fraction of this sink likely located in the tropics, particularly in the Amazon. Nevertheless, it is unclear how the terrestrial carbon sink will evolve as climate and atmospheric composition continue to change. Here we analyse the historic evolution of the biomass dynamics of the Amazon rainforest over three decades using a distributed network...

Biomass data from 'Forest biomass density across large climate gradients in northern South America is related to water availability but not with temperature'Esteban Álvarez-Dávila, Luis Cayuela, Sebastián González-Caro, Ana M.

Understanding and predicting the likely response of ecosystems to climate change are crucial challenges for ecology and for conservation biology. Nowhere is this challenge greater than in the tropics as these forests store more than half the total atmospheric carbon stock in their biomass. Biomass is determined by the balance between biomass inputs (i.e., growth) and outputs (mortality). We can expect therefore that conditions that favor high growth rates, such as abundant water supply, warmth,...

1. Quantifying the relationship between tree diameter and height is a key component of efforts to estimate biomass and carbon stocks in tropical forests. Although substantial site-to-site variation in height-diameter allometries has been documented, the time consuming nature of measuring all tree heights in an inventory plot means that most studies do not include height, or else use generic pan-tropical or regional allometric equations to estimate height. 2. Using a pan-tropical dataset of 73 plots...

Data package for 'Untangling the importance of niche breadth and niche position as drivers of tree species abundance and occupancy across biogeographic regions '. Global Ecology and Biogeography 2020. ABSTRACT Despite decades of interest in how ecological niches shape species commonness and rarity at local and regional scales, the relative importance of different niche mechanisms within and across ecosystems remains unresolved. We tested the relative importance of niche breadth (range of environmental conditions where species...

Forest inventory plots are widely used to estimate biomass carbon storage and its change over time. While there has been much debate and exploration of the analytical methods for calculating biomass, the methods used to determine rates of wood production have not been evaluated to the same degree. This affects assessment of ecosystem fluxes and may have wider implications if inventory data are used to parameterise biospheric models, or scaled to large areas in assessments...
The extraordinary diversity of Amazonian forests conceals that tree abundance is 121 strongly skewed towards relatively few ‘hyperdominant’ species. In addition to their 122 diversity, Amazonian trees are a key component of the global carbon cycle, 123 assimilating and storing more carbon than any other ecosystem on Earth. Here, we 124 ask, using a unique dataset of 530 forest plots, if the functions of storing and 125 producing woody carbon are concentrated in a small...
Lineages tend to retain ecological characteristics of their ancestors through time. However, for some traits, selection during evolutionary history may have also played a role in determining trait values. To address the relative importance of these processes requires large-scale quantification of traits and evolutionary relationships amongst species. The Amazonian tree flora comprises a high diversity of angiosperm lineages and species with widely differing life history characteristics, providing an excellent system to investigate the combined influences...
RAINFOR field manual for plot establishment and remeasurement (Amazon Forest Inventory Network, 2018)Oliver L. Phillips, Tim R. Baker, Ted R. Feldpausch & Roel J.W. Brienen
RAINFOR (The Amazon Forest Inventory Network, Rede Amazônica de Inventários Florestais, Red Amazónica de Inventarios Forestales) is an attempt to utilise long-term permanent sample plots (PSPs) to monitor forest biomass and dynamics, and relate these observation to soil and climate across the Amazon forest region. Many of these plots were established in the past to investigate specific local ecological or forest management questions. However, by compiling and comparing these studies on a regional scale a...

ABSTRACT: The sensitivity of tropical forest carbon to climate is a key uncertainty in predicting global climate change. Although short-term drying and warming are known to affect forests, it is unknown if such effects translate into long-term responses. Here, we analyze 590 permanent plots measured across the tropics to derive the equilibrium climate controls on forest carbon. Maximum temperature is the most important predictor of aboveground biomass (−9.1 megagrams of carbon per hectare per degree...

Abstract Abstract Aim The accurate mapping of forest carbon stocks is essential for understanding the global carbon cycle, for assessing emissions from deforestation, and for rational land-use planning. Remote sensing (RS) is currently the key tool for this purpose, but RS does not estimate vegetation biomass directly, and thus may miss significant spatial variations in forest structure. We test the stated accuracy of pantropical carbon maps using a large independent field dataset. Location Tropical forests...

Understanding the processes that determine aboveground biomass (AGB) in Amazonian forests is important for predicting the sensitivity of these ecosystems to environmental change and for designing and evaluating dynamic global vegetation models (DGVMs). AGB is determined by inputs from woody productivity (woody NPP) and the rate at which carbon is lost through tree mortality. Here, we test whether two direct metrics of tree mortality (the absolute rate of woody biomass loss and the rate of...

We report above-ground biomass (AGB), basal area, stem density and wood mass density estimates from 260 sample plots (mean size: 1.2 ha) in intact closed-canopy tropical forests across 12 African countries. Mean AGB is 395.7 Mg dry mass ha-1 (95% CI: 14.3), substantially higher than Amazonian values, with the Congo Basin and contiguous forest region attaining AGB values (429 Mg ha-1) similar to those of Bornean forests, and significantly greater than East or West African...
