Summary: Climate change introduces uncertainty in water resources planning, especially for high latitude river systems. A study on the Saint John River Basin reveals that meteorological data significantly affect model performance and can introduce uncertainty in hydrological modeling. The analysis shows that future winter flows are projected to increase, while summer flows may decrease.

Summary: This study investigates the genetic source and diversity of paddy field carp (PF-carp) populations along the Pearl River basin. The results reveal genetic introgression among PF-carp populations and identify common genetic origins. The genetic differentiation among strains is influenced by intensive breeding, farmer connections, and geographic barriers. These findings provide valuable insights into the status of germplasm resources among PF-carp.

Summary: The study reveals a common depositional history in the sedimentary system through analyzing the ages of single-grain K-feldspar luminescence subpopulations. These depositional periods are closely related to climate conditions, indicating a significant climatic control on sediment depositional history in southern California.

Summary: Forest-cover removal globally has caused significant changes in stream and river flow dynamics. This study focused on characterizing the discharge rates in a large, international river in northeastern North America at daily-to-seasonal scales. Over a 19-year period, forest-cover in the upper Saint John River basin was routinely removed, with an increasing trend of 7.7% per year. The study found that daily discharge rates were influenced by snowmelt, snow water equivalent, and forest-cover removal.

Summary: A Bayesian deep learning model was used to reconstruct the emergence and expansion of open habitats in North America, utilizing fossil evidence, geologic models, and paleoclimatic proxies. The study suggests that these habitats originated around 23 million years ago and covered over 30% of North America by the onset of the Quaternary glacial cycles, eventually becoming the most prominent natural vegetation type today.

Summary: This study focuses on the Late Devonian Illinois Basin and establishes a basin evolution model through correlation analysis and high-resolution chemostratigraphic profiles. The study reveals three phases of NAS deposition and identifies four anoxic pulses during the NAS deposition. Correlation analysis with other basin data also links some of the anoxic pulses to key biotic crises in the Late Devonian.

Summary: While the presence of microplastics (MP) in aquatic ecosystems worldwide is known, there is still a lack of understanding regarding the factors and controls influencing their occurrence and distribution. This study examined MP concentrations in water and streambed sediment at various locations in the Neuse River Basin in North Carolina, USA. MP particles with a diameter greater than 335 µm were found in all water samples, with concentrations ranging from 0.02 to 221 particles per cubic meter. Urban streams had the highest concentrations, and a significant correlation between streamflow and MP concentration was observed in urbanized areas. The most common polymer types identified for MPs larger than 335 µm were polyethylene, polypropylene, and polystyrene. When smaller mesh sizes (>64 µm) were used for analysis, a higher concentration of MP particles, with the most common polymer type being polyethylene terephthalate, was observed. The ratio of MP concentrations between the two mesh sizes ranged from 35 to 375, indicating an underestimation of MPs by the larger mesh. MPs were also detected in 14 out of 15 sediment samples. The findings of this study provide valuable insights into the spatial distribution and transport of MPs in river basins, as well as the influences of land cover, hydrology, and sampling methods on MP concentrations.

Summary: Due to environmental pollution and overfishing, the genetic resources of wild loach have been degraded. The study investigated the genetic diversity of different geographical populations of loach in the Pearl River Basin and found that there is abundant genetic diversity, which can be used for breeding. The results provide a theoretical basis for the protection and utilization of loach natural resources in the Pearl River Basin of China.

Summary: A spatio-temporal geostatistical interpolation framework was developed to estimate hypoxia extent using data from a network of DO loggers. The framework was applied to analyze DO dynamics in Lake Erie, demonstrating the ability to capture dynamic nature of bottom hypoxia. The study suggests placing more loggers in nearshore areas to reduce prediction error near the margins of the hypoxic zone.

Summary: Through genome sequencing of 132 North American Vibrio parahaemolyticus isolates, this study revealed the population structure of this species along the Gulf and Atlantic Coasts, with some sequence types shared between the Gulf Coast and the coastal waters of Washington State. The identification of functional gene categories enriched in isolates from clinical sources provides insight into the potential pathogenicity of Vibrio parahaemolyticus and its adaptability in different environments.

Summary: This study applied a two-stage bias correction method to simulate precipitation and temperature data in the Daqing River Basin, finding that future precipitation is projected to increase more in the plains compared to mountains, with precipitation unevenness showing a slight increase in the mountains and a decrease in the plains, along with enhanced seasonality.

Summary: The sedimentary record of the Basin and Range reflects the tectonic evolution of landscapes, while trends in species richness are related to actual increased richness in the Miocene rather than increased fossil burial.

Summary: Based on analyses of observation-based data and numerical weather prediction model output, this study reveals that a warm-season atmospheric river moved from Southeast Asia across the North Pacific in June 2021, contributing heat and moisture to a heatwave event in western North America. The movement of this system resulted in substantial spillover of moisture and sensible heat, forming a positive feedback mechanism that potentially led to the expansion of the heatwave event.

Summary: This study assessed the suitability of different water quality assessment frameworks for quantifying the health of the Sangker River in Cambodia. The US Environmental Protection Agency method was found to be the most suitable for this river, and could potentially be used in data-scarce environments to monitor river ecosystem health.

Summary: DNA replication is a widespread and conserved cellular process, but regulation is only understood in a small fraction of organisms. Research on the replication band in spirotrich ciliates reveals unique forms in different species, with genes related to cellular transport potentially involved in its function and movement.
