How Do Changes in Grassland Phenology and Its Responses to Extreme Climatic Events in Central Asia? by Xinwei Wang, Jianhao Li, Jianghua Zheng, Liang Liu, Xiaojing Yu, Ruikang Tian, Mengxiang Xing

“…Extreme climate events have become more frequent under global warming, significantly affecting vegetation phenology and carbon cycles in Central Asia. However, the mediating effects of intensity of compound drought and heat events (CDHEs) and compound moisture and heat events (CMHEs) on grassland phenology and their trends in the relative contributions to grassland phenology over time have remained unclear. …”

Uncovering novel functions of the enigmatic, abundant, and active Anaerolineae in a salt marsh ecosystem by Paige E. Payne, Loren N. Knobbe, Patricia Chanton, Julian Zaugg, Behzad Mortazavi, Olivia U. Mason

“…The data revealed that the belowground salt marsh Anaerolineae in the rhizosphere are important players in carbon cycling, including degradation of simple carbon compounds and more recalcitrant plant material, such as cellulose, using a diversity of electron acceptors and represent an unexplored reservoir of novel secondary metabolites.IMPORTANCEGiven that coastal salt marshes are recognized as biogeochemical hotspots, it is fundamentally important to understand the functional role of the microbiome in this ecosystem. …”

Contrasting seasonal patterns in particle aggregation and dissolved organic matter transformation in a sub-Arctic fjord by M. G. Digernes, Y. V. Bodur, M. Amargant-Arumí, O. Müller, J. A. Hawkes, S. G. Kohler, U. Dietrich, M. Reigstad, M. L. Paulsen

“…Simultaneously, the DOM pool became more labile during the incubation period, as indicated by changes in the average hydrogen saturation, aromaticity, and oxygen saturation, with implications for carbon cycling. The change in POC was not directly associated with an antagonistic change in DOC concentrations, highlighting the complexity of organic matter transformations, making the dynamics between POC and DOC difficult to quantify. …”

Evaluation of Urban Composite Carbon Sink Value: A Case Study of Shenyang by Tiemao SHI, Di WANG, Yu TANG, Peiying LI

“…With the increasing concerns about climate change and the pursuit of sustainable development, accurately evaluating the carbon sink value becomes essential for understanding the role of different ecosystems in carbon cycling. However, it is highly remarkable that in the current research on ecological compensation of carbon sink, the urban carbon sink value has been frequently overlooked, which is rather concerning given the rapid expansion of urban areas and their growing impact on the environment. …”
