TL;DR: It is found that dominance of forest function is even more concentrated in a few species than is dominance of tree abundance, with only ≈1% of Amazon tree species responsible for 50% of carbon storage and productivity.

TL;DR: It is found that woody NPP is not correlated with stem mortality rates and is weakly positively correlated with AGB, and across the four models, basin‐wide average AGB is similar to the mean of the observations.
Journal ArticleDOI
Quantifying the rate and depth dependence of bioturbation based on optically‐stimulated luminescence (OSL) dates and meteoric 10Be
Michelle O. Johnson,Simon M. Mudd,Brad Pillans,Nigel A. Spooner,L. Keith Fifield,Mike Kirkby,Manuel Gloor +6 more
TL;DR: In this article, the relationship between mixing rate and depth in a bioturbated soil in northeast Queensland, Australia using a novel method combining OSL (optically stimulated luminescence) ages and meteoric beryllium-10 (10Be) inventories was investigated.
Journal ArticleDOI
Insights into biogeochemical cycling from a soil evolution model and long-term chronosequences
TL;DR: In this article, a model for predicting soil evolution over geological timescales is presented, which includes the major processes of pedogenesis: mineral weathering, percolation of rainfall, leaching of solutes, surface erosion, bioturbation, the effects of vegetation in terms of organic matter input and nutrient cycling and can be applied to various bedrock compositions and climates.

A Spatial and Temporal Risk Assessment of the Impacts of El Niño on the Tropical Forest Carbon Cycle: Theoretical Framework, Scenarios, and Implications
Adriane Esquivel-Muelbert,Amy C. Bennett,Martin J. P. Sullivan,Jessica C. A. Baker,Yoni Gavish,Michelle O. Johnson,Yunxia Wang,Alexander Chambers-Ostler,Marta Lisli Giannichi,Luciene Gomes,Michelle Kalamandeen,K. C. Pattnayak,Sophie Fauset +12 more
TL;DR: Overall, the relative risk of El Nino has been increasing driven mainly by intensified forest fragmentation that has led to a greater chance of fire ignition and increased mean annual air temperatures.
