Summary: The study utilized high-resolution chronostratigraphy to reveal two major biological events in the early Paleozoic era: GOBE and LOME. GOBE started in the early Ordovician and ended at the Darriwilian boundary, consisting of two major radiation phases; while the Late Ordovician witnessed two extinction events resulting in a regional species loss of approximately 67%.

Summary: The study assessed the diversity and assembly of soil bacterial and fungal communities in mountain ecosystems, showing that the bacterial diversity displayed a U-shaped pattern along altitudes while the fungal diversity decreased monotonically with increasing altitude. Soil bacterial and fungal communities were distinctively distributed with altitude at the same soil depth, and the spatial turnover rates in fungi were greater than in bacteria. Soil physiochemical and climate variables significantly correlated with the beta diversity of microbial community at two soil depths, suggesting both soil and climate heterogeneity contributed to the variation of bacterial and fungal community. The assembly processes of bacterial community were significantly related to the soil DOC and C:N ratio, while the fungal community assembly processes were significantly related to the soil C:N ratio.

Summary: The spatial distribution of snow has a significant impact on sub-Arctic and Arctic climate, hydrology, and ecology. However, the understanding and modeling of snow distribution is limited, leading to uncertainties in snow cover representations. Through intensive field studies and modeling, the random forest model proved to be successful in capturing the complexity and variability of snow characteristics.

Summary: Based on research in the Yangtze Shelf Sea, two intervals of phosphorus recycling were found, which played a critical role in the occurrence of the Late Ordovician mass extinction.

Summary: This study investigates the characteristics, distribution, and origin of ferruginous deposits found in the Late Ordovician glaciogenic Sarah Formation and surrounding deposits in central Saudi Arabia. Several types of ferruginous deposits have been identified, including solid and rinded concretions, pipes, layers, ferricretes, liesegang bands, and fracture infills. Goethite was the dominant iron oxide mineral in all ferruginous deposits. Compared to ferruginous deposits reported in different depositional settings, the studied ferruginous deposits in an ancient glaciogenic setting exhibit different mineralogical characteristics.

Summary: Surface energy is a crucial stability descriptor for transition metal-based catalysts. In this study, we developed a computational model using density functional theory (DFT) calculations and a tiling scheme to predict the average surface energy of metal structures, regardless of their shape. The model accurately predicts the surface energy of metallic surfaces of various crystal structures, nanostructures, and sub-nanometer clusters, by combining Lorentzian trends derived from DFT data and machine-learning algorithms.

Summary: This study investigates the biogeographic histories of two cosmopolitan groups of Olenida, Hypermecaspididae and Parabolinella (Olenidae). Different biogeographical models were compared, and the results suggest that jump dispersal was an important speciation strategy for both groups. Vicariance was found to be unimportant. The dispersal patterns of Parabolinella were influenced by ocean currents, while those of Hypermecaspididae were not. Island hopping and creeping were the main dispersal mechanisms for both groups. The western margin of Gondwana played a significant role as a dispersal center during the Furongian and Early Ordovician.

Summary: This study presents a novel conceptual design based on phase engineering theory to enhance the spatial transportation of photocarriers in efficient photocatalytic hydrogen evolution. The introduction of black phosphorus nanodots extends the utilization of incident photons, resulting in improved hydrogen evolution activity and quantum yields. This strategy provides insights for the design of superior photocatalytic systems with enhanced solar conversion efficiency.

Summary: The presence of sedimentary sequences at specific temperature ranges allows for the identification of economically important hydrocarbon accumulation patterns. This study presents global distribution maps of the "Golden Zone" which represents the area where petroleum system elements can coexist without significant degradation. The maps show variations in different geotectonic environments, with thin sedimentary sequences along active tectonic margins and a wide range of thicknesses within basins on passive margins.

Summary: Biotic immigration events, in which organisms from one geographic region invade and become established in a new region, have had significant impacts on diversification patterns and processes throughout Earth history. The Richmondian Invasion is a well-studied example of such events, with multiple waves of invasion into the Cincinnati Basin during the Katian Stage. Detailed studies have documented the general patterns of this invasion and its effects on paleocommunities, establishing it as a coordinated invasion within the Invasion Hierarchy.

Summary: This study reports for the first time a series of voluminous intraplate volcanic events in Iran, which may be a key factor contributing to the Late Ordovician mass extinction (LOME). The volcanic events occurred during the initial rifting of the Paleotethys Ocean and have been identified through fieldwork and dating techniques. The researchers suggest that these volcanic activities represent remnants of a newly proposed Large Igneous Province (LIP) and played a significant role in the environmental and climatic changes associated with LOME.

Summary: This article presents a chronology framework called LegacyAge 1.0, which includes harmonized chronologies for 2831 pollen records along with their age control points and metadata. The chronologies were created using a Bayesian framework and optimal parameter settings. Calibrated radiocarbon dates were used as the most common control points, and outliers and inconsistencies were addressed by consulting the original publications. The LegacyAge 1.0 chronologies were numerically compared to the original publications, resulting in improved reliability for 95.4% of the records. This chronology framework and revised chronologies offer opportunities for synthesis studies on pollen-based vegetation and climate change.

Summary: The hydrological conditions in Lake Poyang are complex due to its connection with the Yangtze River, leading to unique drivers of phytoplankton distribution. Phytoplankton density has been increasing annually, with water temperature, water flow velocity, and Secchi depth identified as key drivers. Changes in dominant genera are influenced by nutrients and water flow velocity, with decreases in nutrient concentrations observed in recent years.

Summary: Climate changes may threaten the survival of felids by driving range shifts, altering biogeographical characteristics of their range, and decreasing range overlap with protected areas. Countries facing significant landcover changes such as Brazil, China, and India are also priority areas for felids conservation, highlighting the urgency and potential challenges in safeguarding felids. Expanding protected areas in felids distribution regions is necessary as the protected area network overlaps with just a small percentage of their current and future distribution.
