Effects of Different Processing Methods on the Content of Rutin and Tannin in Sophora japonica Herb Medicine
Objective: To investigate the effects of different processing methods on the content of rutin and tannin in Sophora japonica herb medicine (Chinese herb medicine name: Huai Mi or Huai Hua).
Methods: Huai Mi was processed with different methods. Tannin content was determined using potassium permanganate titration method. Rutin content was quantified using ultraviolet spectrophotometry.
Results: The tannin content was the highest in stir-fried-to-coke samples (1.87%), while the highest rutin content was observed in stir-fried-to-yellow samples (0.134%). The stir-fried-to-ash samples had the lowest contents of both rutin and tannin.
Conclusion: Processing methods critically impact the contents of bioactive compounds in Sophora japonica herb medicine. Optimizing these methods may enhance medicinal efficacy and utilizatio

Deriving best use data from NEON for mosquito research applications: A practical guide with code
The National Ecological Observatory Network (NEON) is a long-term monitoring program at the continental scale designed to understand and forecast ecological responses to environmental change at local to broad scales. However, despite robust and nearly continuous collections, NEON mosquito data have been underused in downstream analyses. Here, we provide species-level estimated abundances for nighttime collected female mosquitoes derived from the mosquitoes sampled from CO2 traps (DP1.10043.001) (RELEASE-2024; NEON, 2024). By including zero counts, our derived data complement existing data sets and provide an analysis-ready time series useful for investigating mosquito phenology, abundances, and diversity at the species or community level. We also outline a set of considerations specific to filtering NEON mosquito data by sex and for day or nighttime collections, highlighting factors that could introduce uncertainty to abundance estimates. Along with the data set, we provide an R Markdown file that includes annotated code and documents our data filtering and QC/QA steps, as well as data files used to filter the mosquito data based on QC/QA criteria. All files are freely available for download through the Environmental Data Initiative data portal. Our reproducible and fully documented workflow can be easily adapted for specific needs or other NEON surveillance data. Our work aims to enhance the accessibility and use of NEON’s rich, long-term monitoring data
Stopover hotspots for migratory birds in North and Central America
Despite the large body of literature on avian migratory behavior, there is little information about stopover sites during bird movement, including the population-level drivers of breeding grounds and wintering grounds. Stopovers play an essential role in bird migratory site chains for energy supply and rest. There is an urgent need to detect and protect stopover sites to secure the long-term sustainability of migratory network connectivity and robustness. To address this challenge, we reconstructed a migration network and identified geographic hotspots denoted as stopover sites by analyzing the high-density population movements of 52 focal migratory bird species with observation data from eBird through PageRank algorithm. Furthermore, potential alternative stopover sites were explored using a word embedding technique based on geo-functional similarity. Our study was conducted in North and Central America during a three-year period and revealed three key areas, including Florida peninsula and its inland, the region of Central America, and the region near Puget Sound. Results from this study can be used for conservation prioritization guidance
