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. …”

Biomass Potentials and Carbon Storage of Wooden Plants in the Community Forest of Nglanggeran Village, Gunungkidul Regency, Yogyakarta by Ris Hadi Purwanto, Rohman Rohman, Ahmad Maryudi, Teguh Yuwono, Dwiko Budi Permadi, Makmun Sanjaya

“…Community forests, like any other forests, do not only produce timber and fire-woods but they also function as carbon storage, and therefor they play a very important role in the global carbon cycle. This research aims were (a) determining the types of perennial woods (diameter at breast height, D = 10 cm which grown on community forest of Ngalaggeran Village, (b) determining the growth characteristics of vegetations which make up the community forest, including diameter at breast height, height of trees, tree density and basal area, and (c) determining the biomass and carbon storage in the community forests of Nglanggeran Village.The research used the allometric method to assess the biomass of mahagony, acacia, sonokeling, teak, sengon and the others. …”

Mineralogy as a potential driver of irregular radiocarbon patterns among Icelandic fluvial carbon pools by Nora Gallarotti, Lisa Bröder, Julie Lattaud, Stephan Wartenweiler, Negar Haghipour, Timothy I Eglinton

“…Fluvial export of organic carbon (OC) from the terrestrial biosphere to the ocean forms a key component of the global carbon cycle. Carbon sources and transformations along the land–ocean aquatic continuum are dynamic with a complex interplay between particulate and dissolved organic and inorganic carbon pools (POC, DOC, DIC). …”

A new approach to continuous monitoring of carbon use efficiency and biosynthesis in soil microbes from measurement of CO₂ and O₂ by K. E. Smart, D. O. Breecker, C. B. Blackwood, C. B. Blackwood, C. B. Blackwood, T. M. Gallagher

“…Therefore, understanding processes that control soil carbon stabilization and release is vital to improving our understanding of the global carbon cycle. Heterotrophic respiration is the main pathway by which soil organic carbon is returned to the atmosphere; however, not all carbon utilized by heterotrophs shares this fate, as some portion is retained in the soil as biomass and biosynthesized extracellular compounds. …”
