Summary: The response of terrestrial ecosystems to increased CO2 concentrations is not fully understood. Although there is consensus that increased CO2 affects instant processes, such as photosynthesis, uncertainties remain regarding the fate of assimilated carbon. This study proposes the use of transit time distributions to assess the fate of newly assimilated carbon and calls for its adoption to improve our understanding of ecosystem responses to increased CO2.

Summary: This study presents an empirical model, SOCSEM, to assess the potential impact of soil OCS exchange on regional stomatal conductance. The model uses soil moisture and surface temperature as input data and characterizes soil OCS exchange. Comparisons with field-based observations reveal deviations due to missing complexity in the model design. The study also investigates the applicability of the model in agricultural regions with known net emissions and regions with unknown soil OCS responses, such as Arctic tundra. Further research on non-stomatal surfaces and different ecosystems will increase confidence in using OCS as a regional tracer for stomatal conductance.

Summary: The rhizosphere is a dynamic interface on Earth and understanding its effects on soil microbial communities is important. The rhizosphere effects on soil C and nutrients, microbial biomass, specific microbial groups, respiration, and C-degrading enzymes were positive. However, the magnitude of these effects varied with biomes, plant functional types, and mycorrhizal types.

Summary: This study compiled and updated a database of terrestrial plant organic carbon isotope data, revealing a gradual decrease in carbon isotope ratios of plant material from the Mesozoic to the Cenozoic. Comparisons with marine carbonate carbon isotope ratios and atmospheric CO2 carbon isotope ratios showed both correspondence and divergence, indicating the presence of major carbon cycle and/or climatic events. A key finding is an increased discrimination in both plant organic carbon and atmospheric CO2 carbon isotope records starting from the Miocene Climatic Optimum.

Summary: Potassium presents a dilemma for biogeochemists. While it is inefficiently cycled at the plant level, it seems to be conserved at the ecosystem level, sometimes limiting net primary productivity. The increasing demand for K fertilizer in agriculture, especially in highly weathered tropical soils, may control the distribution and productivity of natural vegetation. However, the molar ratios of N/K in herbaceous plants, global fertilizer applications, and commodity price of fertilizer suggest that nitrogen is overused and potassium is overpriced in modern agriculture.

Summary: The productivity and life-supporting capacity of ecosystems depend on access to reactive nitrogen. However, long-term records show that nitrogen availability is declining in many regions of the world. Global changes, such as elevated atmospheric carbon dioxide levels and rising temperatures, are affecting the balance between ecosystem nitrogen supply and demand. This decline in nitrogen availability is limiting primary productivity and reducing the quality of herbivore diets in many ecosystems. We outline the current state of knowledge about declining nitrogen availability and propose actions to address this emerging challenge.

Summary: Increased human-derived nitrogen loading in terrestrial ecosystems has led to widespread phosphorus limitation. Plants and soil micro-organisms adopt phosphorus-acquisition strategies to offset this limitation, but these strategies come at a cost to carbon allocation. The effects of these strategies on soil carbon cycling are still unclear.

Summary: Microplastics less than 5 mm in size are persistent pollutants that significantly impact terrestrial ecosystems by degrading soil fertility and microbiomes. These microplastics lead to changes in soil characteristics, nutrient cycling, and potential climate risks. Understanding their sources, composition, abundance, life cycle, and transport is a major challenge and important global topic of debate among scientists. This review focuses on bridging the knowledge gap by discussing the potential sources, transport, and disintegration of microplastics in terrestrial ecosystems, as well as their effects on soil characteristics and nutrient cycling. The identified scientific gaps can aid environmentalists, microbiologists, hydrologists, and policymakers in understanding microplastic pollution and exploring future engineering solutions.

Summary: This study conducted a comprehensive meta-analysis to evaluate the specific response of microbial- and plant-derived carbon to warming. The results showed that climate warming led to an increase in terrestrial soil carbon pools, with microbial-derived carbon showing a higher increase than plant-derived carbon. Additionally, the response of different carbon sources to warming was influenced by factors such as warming duration, magnitude, ecosystem type, and climatic zone.

Summary: The Earth's mantle releases CO2 and other gases to the atmosphere, shaping microbial metabolism at volcanic sites globally. However, little is known about the impact of mantle degassing on microbial life under non-thermal conditions. In this study, researchers compared microbial communities from a cold-water geyser with other deep subsurface sites, and found that an uncultivated archaeon played a key role. These findings suggest that subsurface ecosystems affected by geological degassing are important for microbial life in the deep biosphere.

Summary: Excessive nitrogen deposition in forest ecosystems in Germany has led to accelerated plant growth, increased internal nitrogen cycling, and enhanced retention of nitrogen in soil and plant compartments. The impact of European beech fructification on nitrogen fluxes is not well understood, with limited research on the frequency of mast events and their effects on nitrogen cycling. Further research is needed to understand the role of mast products in nitrogen retention in forest ecosystems.

Summary: The magnitude and distribution of China's terrestrial carbon sink remains uncertain, and this study uses satellite data to provide two estimates of the carbon sink. The results suggest that the carbon sinks are mainly located in central and eastern China and are vital for characterizing terrestrial net carbon fluxes at regional scales.

Summary: The study investigates the provenance of Lower Cretaceous deposits in the Phuquoc Basin, revealing that the Qinling-Dabie and Songpan-Ganzi orogenic belts were major sources of sediment in the Early Cretaceous. The analysis of detrital zircon and heavy mineral compositions suggests a common sediment source with Khorat and Sichuan basins, and similarities with mid-Cretaceous strata in the Lanping-Simao Basin. This supports the idea that the Phuquoc, Khorat, Sichuan, and possibly the Lanping-Simao basins were part of a Cretaceous basin in central SE Asia.

Summary: The study investigates a distant impact ejecta layer near Bernhardzell in Switzerland, providing evidence of its impact-related nature through analysis of shocked quartz grains and U-Pb dating of zircon grains. The age and origin of the Blockhorizont are constrained through these analyses, consistent with deposition as distal impact ejecta from the Ries impact structure in Germany. The observations help constrain models of impact ejecta emplacement and highlight the preservation of the Ries ejecta as a significant event in Earth's history.

Summary: The Kap Stewart Group in central East Greenland, traditionally considered a continental unit, is now believed to have experienced marine influence based on new findings of plesiosaur bone remains. The bonebearing sandstone layer in the Rhaetelv Formation of the group can be dated back to the Hettangian period, around 200 million years ago. This discovery provides a numerical age constraint for a previously poorly dated succession.

Summary: This research report introduces a new species of giant carnivorous dinosaur called Meraxes gigas, which has almost complete forelimbs and provides new evidence for the trend of forelimb reduction in theropod dinosaurs. The research also reveals that the diversity of carcharodontosaurids reached its peak before extinction, and the evolution rate of facial ornamentation may be linked to social signaling.

Summary: Late Jurassic dinosaurs showed a range of dental complexities similar to modern saurians, with theropods having simple teeth due to their carnivorous habits, and ornithischians exhibiting complex dentitions related to herbivory. Macronarian sauropods present a unique herbivory strategy with tooth complexity linked to replacement rate instead of diet.
