Summary: This study investigates the improvement of hydrologic prediction accuracy by considering multiple parameter sets in addition to multiple model representations. Various ensemble methods were tested, and it was found that the multi-parameter ensemble approach outperformed the multi-model ensemble approach in improving modeling accuracy.

Summary: Occupancy modeling can overcome the limitations of rapid disease tests to provide fast, accurate, and affordable estimates of disease prevalence. It allows for the use of rapid tests to provide real-time estimates of emerging infectious diseases like SARS-CoV-2, even with their lower sensitivity compared to slower tests.

Summary: Plant biomass, especially wood, has long been used as structural materials and is showing great potential for developing new structural materials. This article reviews the structure, properties, and reactions of cellulose, lignin, and wood cell walls using computational modeling methods, such as density functional theory (DFT) and molecular dynamics (MD), which may play a leading role in developing new hierarchical materials from biomass in the future.

Summary: Heterogeneities in infections among host populations can arise from differences in environmental conditions affecting host exposure and susceptibility to pathogens. The study found that variation in pathogen mortality rates among different water sources drove differences in infection prevalence, rather than differences in per capita transmission rates. This suggests that environmental factors influencing pathogen survival may play a key role in infection dynamics.

Summary: Polymicrobial sepsis has worse patient outcomes than monomicrobial sepsis. Culture-dependent diagnostic techniques have low sensitivity, leading to missed identification of causative organisms. Culture-independent methods using molecular technologies show promise, but issues such as contamination and interference from host DNA need to be addressed. This review discusses the clinical significance of polymicrobial sepsis and how alternative molecular microbiology methods can be improved to detect polymicrobial infections.

Summary: In Greek vineyards, GVA is the most prevalent virus, followed by GRSPaV and GVB. The incidence of viruses differs among self-rooted and grafted grapevine cultivars or rootstocks tested. High nucleotide diversity was observed in all three viruses, with isolates in Greece belonging to various phylogroups, suggesting multiple introductions and different transmission modes of GVA, GVB, and GRSPaV in Greece.

Summary: This paper proposes an improved sub-step time-marching procedure for structural dynamics, with two free parameters to control algorithmic properties. The optimal parameter value is obtained through studying the influences of the algorithmic parameters. Theoretical analysis and numerical simulations show that the new procedure is desirable for both linear and nonlinear dynamics.

Summary: Species richness is a crucial indicator of ecosystem states and dynamics, but limited sampling effort and spatial aggregation of organisms hinder accurate observation of every species. In this study, we propose a non-parametric, asymptotic, and bias-minimized estimator called omega, which accounts for spatial abundance characteristics. Our simulation tests and real surveys demonstrate that omega consistently outperforms other estimators in balancing bias, precision, and difference detection accuracy. An R-package, Richness, is developed to facilitate the implementation of our proposed estimators. Our findings shed light on the impact of natural and observer-induced variations on species observation, and emphasize the importance of further improving biodiversity assessments.

Summary: Bivariate wavelet coherency is a useful measure for exploring relationships between variables in geoscience, but can be misleading when variables are dependent on others. A new Partial wavelet coherency (PWC) method has been developed to handle multiple excluding variables and provide phase information, showing improved performance in capturing bivariate relationships in geoscience after removing the effects of other variables.

Summary: This study developed a new approach for efficient elimination of foodborne pathogens by fabricating Fe3O4-Chitosan (CS)/polyvinyl alcohol (PVA) nanofibrous films with improved antibacterial and mechanical properties. The films with smooth and bead-free nanofibrous structures showed enhanced bacterial attachment and inactivation efficiency with Fe3O4 loading, particularly against Escherichia coli (E. coli) and Staphyloccus aureus (S. aureus). The films also exhibited increased tensile strength and elongation at break, indicating improved mechanical properties. The findings suggest a promising strategy for effective foodborne pathogens elimination.

Summary: The study reviewed goal themes of fisheries bureaus and identified nine distinct themes, which do not exhibit clear geographic patterns as presumed. Since the 1970s, there has been an expansion in fisheries bureau goals and a disappearance of regionalism in goal setting. Changes in perspectives, communication technology, and nationwide funding mechanisms have led to more homogeneous goals across the USA and greater diversity within each bureau.

Summary: This study examines the impact of an atypical strain of Aeromonas hydrophila in channel catfish aquaculture, providing insights into rapid field sampling methods and the importance of accurate quantitative PCR detection. Results show that the location of swab collection (gill vs. lower intestine) on pond-raised catfish is affected by the pond's condition, with implications for prevalence estimates and outbreak risk assessment. Furthermore, the study highlights the presence of a carrier state of the pathogen in apparently healthy fish, suggesting avenues for future research on disease mechanisms in catfish aquaculture.

Summary: Comparison of sperm cryopreservation procedures between black-stripe black crappie and white crappie showed that using 5% DMSO resulted in higher fertilization rates than 10% methanol. Therefore, basic protocols can be generalized within a genus by controlling variables such as sperm concentration, process timing, and sample volumes.

Summary: The study conducted a multiweek standardized sampling regime from 2004 to 2016 in a 60-km reach of the Upper Missouri River to assess the reproduction and catch rates of Sturgeon Chub and Sicklefin Chub. The results indicated a decline in catch per unit area (CPUA) for age-0 Macrhybopsis and Sturgeon Chub, potentially influenced by the addition of hatchery-origin Pallid Sturgeon. The study also found evidence of a modest recovery of Sicklefin Chub after 2012.

Summary: Environmental management often involves decision-making under uncertainty, such as the case of planting mudflats as supplemental fish habitat in flood control reservoirs. Different reservoirs have varying optimal planting decisions depending on elevation contours. The study provides a quantified basis for establishing best management practices.

Summary: Brush piles installed in reservoirs to supplement fish habitat experience loss and dimensional change over time. This study evaluated the retention and dimensional change of brush piles in a drawdown reservoir embayment and found that brush piles were lost at 10% per year, with a volume loss of 14% per year. The spatial patterns of retention and dimensional change were influenced by physical forces at installation locations. These estimates can be used to sustain desirable brush densities in similar reservoirs.

Summary: In semelparous Pacific salmon, increased cortisol levels during sexual maturation may contribute to rapid senescence and death after spawning. High cortisol levels can lead to energy depletion and reduced immune capacity, increasing susceptibility to parasites and pathogens. This study aimed to determine the extent of the cortisol stress response in spring Chinook salmon and the dynamics of resting cortisol during maturation. The results showed that resting and stressed cortisol levels increased during the last three months prior to spawning. Additionally, the effects of stress and time on cortisol dynamics differed between males and females, as well as between individuals, which has implications for population resilience to anthropogenic stressors in the wild.

Summary: This study found that enhancing fish habitat in reservoirs can be achieved by planting agricultural crops on exposed shorelines, and different plants have varying potential to provide effective fish habitat. Prey fish and predator fish showed distinct preferences in plant selection, and prey schooling increased in response to predation risk.
