Background: Movement behavior strongly mediates species and environment interactions, yet our understanding is constrained by challenges tracking space use at fine spatiotemporal resolutions.
Methods: Using an automated telemetry array, we quantified variation in and drivers of space use for a nonbreeding population of migratory bird, the American redstart Setophaga ruticilla.
Results: We identified two distinct and common behaviors - territoriality and floating,- that were governed primarily by NDVI as a proxy of resource availability.

Light conversion films are crucial for optimizing vegetable crop production in greenhouses, particularly during winter and spring seasons. This study investigated the effects of a europium-based light conversion film (RPO) compared to traditional polyolefin film (PO film, control) on cucumber (Cucumis sativus L.) cultivation, focusing on handle length, yield, and fruit quality in a randomized complete block design with three replications.

Data is the core foundation of intelligent operation and maintenance, but currently, there is generally insufficient data for wastewater treatment plants, and the status of wastewater treatment systems dynamically evolves with the changes in the internal and external environment. The intelligent operation and maintenance of wastewater plants face difficulties in modeling and model drift caused by system evolution. In response to this issue, the summer and winter seasons with significant differences in wastewater temperature, wastewater quality, and microbial status were selected as typical comparison scenarios.

The study of terrestrial phosphorus inflow (hereafter referred to as phosphorus inflow) fluxes is essential for controlling non-point source (NPS) pollution. The SWAT model was successfully used to simulate phosphorus inflow fluxes in the Dongting Lake area, while a hybrid model (LSTM and SWAT) was developed and validated for predicting the reduction in phosphorus inflow fluxes among rivers based on three typical reduction scenarios: agricultural control, livestock and poultry reduction, and soil and water conservation measures. The results showed that the inflow flux of TP was 3.

To achieve non-carbon dioxide greenhouse gas emission reduction and control in municipal wastewater treatment plants (WWTPs), this study conducted one-year long-term monitoring of nitrous oxide (NO) in the anaerobic-anoxic-aerobic (AO) process of a large-scale municipal wastewater treatment plant in Beijing. The experimental results showed that the anaerobic and anoxic zones of the AO process could effectively remove dissolved NO contained in the return sludge, while the aerobic zone was the main area for NO generation and emission, and its generation pathway may have been dominated by ammonia oxidizing bacteria (AOB) denitrification. A significant difference was observed between winter and summer NO production, and the difference in the average NO release flux was up to 7.
