Atmospheric CO2 effect on stable carbon isotope composition of terrestrial fossil archives.
The 13C/12C ratio of C3 plant matter is thought to be controlled by the isotopic composition of atmospheric CO2 and stomatal response to environmental conditions, particularly mean annual precipitation (MAP). The effect of CO2...
Carbon flux through photosynthesis and central carbon metabolism show distinct patterns between algae, C3 and C4 plants.

Photosynthesis-related pathways are regarded as a promising avenue for crop improvement. Whilst empirical studies have shown that photosynthetic efficiency is higher in microalgae than in C3 or C4 crops, the underlying reasons...
Model approaches to advance crassulacean acid metabolism system integration.
This review summarises recent progress in understanding crassulacean acid metabolism (CAM) systems and the integration of internal and external stimuli to maximise water-use efficiency. Complex CAM traits have been reduced to...
Aged soils contribute little to contemporary carbon cycling downstream of thawing permafrost peatlands.
Andrew J Tanentzap, Katheryn Burd, McKenzie Kuhn, Cristian Estop-Aragonés, Suzanne E Tank, David Olefeldt
Jun 11, 2021
Vast stores of millennial-aged soil carbon (MSC) in permafrost peatlands risk leaching into the contemporary carbon cycle after thaw caused by climate warming or increased wildfire activity. Here we tracked the export and...

A critique of general allometry-inspired models for estimating forest carbon density from airborne LiDAR.
There is currently much interest in developing general approaches for mapping forest aboveground carbon density using structural information contained in airborne LiDAR data. The most widely utilized model in tropical forests...
Ocean acidification and the Permo-Triassic mass extinction.
MO Clarkson, SA Kasemann, RA Wood, TM Lenton, SJ Daines, S Richoz, F Ohnemueller, A Meixner, SW Poulton, ET Tipper
Jun 07, 2019
Ocean acidification triggered by Siberian Trap volcanism was a possible kill mechanism for the Permo-Triassic Boundary mass extinction, but direct evidence for an acidification event is lacking. We present a high-resolution...
Accelerating the carbon cycle
Enhanced weathering, in comparison to other geoengineering measures, creates the possibility of a reduced cost, reduced impact way of decreasing atmospheric carbon, with positive knock-on effects such as decreased oceanic...
Marine siliceous ecosystem decline led to sustained anomalous Early Triassic warmth.

Jul 19, 2022
In the wake of rapid CO2 release tied to the emplacement of the Siberian Traps, elevated temperatures were maintained for over five million years during the end-Permian biotic crisis. This protracted recovery defies our current...

Tropical forests play a major role in the carbon cycle of the terrestrial biosphere. Recent field studies have provided detailed descriptions of the carbon cycle of mature tropical forests, but logged or secondary forests have...
Feasting on terrestrial organic matter
Boreal lakes are major components of the global carbon cycle, partly because of sediment-bound heterotrophic microorganisms that decompose within-lake and terrestrially derived organic matter (t-OM). The ability for sediment...
Direct response of tree growth to soil water and its implications for terrestrial carbon cycle modelling.
Annemarie H Eckes-Shephard, Egor Tiavlovsky, Yizhao Chen, Patrick Fonti, Andrew D Friend
Oct 26, 2020
Wood growth constitutes the main process for long-term atmospheric carbon sequestration in vegetation. However, our understanding of the process of wood growth and its response to environmental drivers is limited. Current...
A Rubisco-binding protein is required for normal pyrenoid number and starch sheath morphology in Chlamydomonas reinhardtii.

A phase-separated, liquid-like organelle called the pyrenoid mediates CO2 fixation in the chloroplasts of nearly all eukaryotic algae. While most algae have 1 pyrenoid per chloroplast, here we describe a mutant in the model alga...
