A Large and Persistent Carbon Sink in the World’s Forests
TLDR
The total forest sink estimate is equivalent in magnitude to the terrestrial sink deduced from fossil fuel emissions and land-use change sources minus ocean and atmospheric sinks, with tropical estimates having the largest uncertainties.
Towards a worldwide wood economics spectrum.
TLDR
It is suggested that, similar to the manifold that tree species leaf traits cluster around the 'leaf economics spectrum', a similar 'wood economics spectrum' may be defined.
Benchmark map of forest carbon stocks in tropical regions across three continents
TLDR
A “benchmark” map of biomass carbon stocks over 2.5 billion ha of forests on three continents, encompassing all tropical forests, for the early 2000s is presented, which will be invaluable for REDD assessments at both project and national scales.
TRY – a global database of plant traits
TLDR
The improved availability of plant trait data in the unified global database is expected to support a paradigm shift from species to trait-based ecology, offer new opportunities for synthetic plant trait research and enable a more realistic and empirically grounded representation of terrestrial vegetation in Earth system models.
Variation in wood density determines spatial patterns inAmazonian forest biomass
Uncertainty in biomass estimates is one of the greatest limitations to models of carbon flux in tropical forests. Previous comparisons of field‐based estimates of the aboveground biomass (AGB) of
Increasing carbon storage in intact African tropical forests
TLDR
Taxon-specific analyses of African inventory and other data suggest that widespread changes in resource availability, such as increasing atmospheric carbon dioxide concentrations, may be the cause of the increase in carbon stocks, as some theory and models predict.
Drought Sensitivity of the Amazon Rainforest
TLDR
Records from multiple long-term monitoring plots across Amazonia are used to assess forest responses to the intense 2005 drought, a possible analog of future events that may accelerate climate change through carbon losses and changed surface energy balances.
Defining the Anthropocene
TLDR
The evidence suggests that of the various proposed dates two do appear to conform to the criteria to mark the beginning of the Anthropocene: 1610 and 1964.
Increasing biomass in Amazonian forest plots.
TLDR
The results presented here suggest that the total biomass of these plots has on average increased and that there has been a regional-scale carbon sink in old-growth Amazonian forests during the previous two decades.
The 2010 Amazon Drought
TLDR
A decade of satellite-derived rainfall data is analyzed to compare both the 2010 and 2005 drought in Amazonia and predict the impact of the 2010 drought as 2.2 × 1015 grams of carbon, largely longer-term committed emissions from drought-induced tree deaths.
