Regional Soil Patterns as Indicators of Late Cenozoic Change in the Critical Zone: A Baseline Synthesis for the Landscapes of Peninsular India by Yanni Gunnell, Nicolas Durand, Shanti Pappu

“…In a region mostly devoid of carbonate rock outcrops, the widely distributed pool of soils hosting abundant accumulations of pedogenic CaCO3 also reveals the magnitude of silicate bedrock weathering as a process for generating secondary calcium carbonate in the rock cycle, thereby highlighting an under-appreciated contribution to inorganic carbon sequestration in the global carbon cycle. The results and maps produced provide exploration tools for future, more systematic and coordinated investigations of the nature and chronology of Quaternary deposits in peninsular India. …”

A machine learning model using the snapshot ensemble approach for soil respiration prediction in an experimental Oak Forest by S.N. Ferdous, J.P. Ahire, R. Bergman, L. Xin, E. Blanc-Betes, Z. Zhang, J. Wang

“…However, because it is highly sensitive to the environment and has large temporal and spatial variability, its contribution to the global carbon cycle remains highly uncertain. Recent advances in ecosystem process models have uniquely constrained soil respiration rates, largely based on results from tracing ecosystem CO2 losses using radioisotope and stable isotope methods. …”

A stomatal optimization model integrating leaf stomata-photosynthetic capacity regulation in response to soil water stress by Yong Liu, Tiesong Hu, Rui Zhu, Qiuwen Chen, Xiang Zeng, Peiran Jing, Yifan Huang

“…Leaf stomatal regulation of water-carbon exchange processes plays a crucial role in the water-carbon cycle. Uncovering the response mechanism of leaf gas exchange to soil water stress is challenging due to the complex effects of both the stomatal regulation (i.e., stomatal conductance, gs) and non-stomatal regulation (i.e., photosynthetic carboxylation capacity, Vcmax25). …”
