Effects of genetic selection and threonine on meat quality in Pekin ducks
Poultry Science, 2020 The present study was conducted to investigate the effects of genetic selection and threonine levels on meat quality in Pekin ducks. At 15 D of age, 192 lean ducks and 192 fatty ducks were selected and allotted to one of three treatments with 8 ...

Radiomarking brood‐rearing mallard females: Implications for juvenile survival
Wildlife Society Bulletin, 2012 Radiotelemetry is frequently used to measure habitat use, movements, and survival in birds; presumably, outfitting adult females with radiotransmitters does not influence juvenile survival, but this critical assumption is rarely tested.

Evidence of vertical transmission of novel duck orthoreovirus in ducks [PDF]
Veterinary Microbiology, 2020 Since 2017, duck spleen necrosis caused by new variant duck orthoreovirus (N-DRV) infection had been observed in several provinces in China. This disease retards the growth and development of ducks, thereby reducing feed return rate. N-DRV infection causes damage to duck spleen and other immune organs, leading to immunosuppression and susceptibility to

Patterns of duck Tembusu virus infection in ducks, Thailand: a serological study
Poultry Science, 2021 Duck Tembusu virus (DTMUV), a mosquito-borne flavivirus, has been identified as a causative agent of an emerging viral disease in ducks, causing significant economic losses to the duck-producing industry. In Thailand, DTMUV has been detected sporadically

Long‐term trends in weather severity indices for dabbling ducks in eastern North America
Wildlife Society Bulletin, 2017 Annual distributions of waterfowl during the nonbreeding period can influence ecological, cultural, and economic relationships. We used previously developed Weather Severity Indices (WSI) that explained migration by dabbling ducks in eastern North ...

Human‐in‐the‐Loop Object Segmentation for 3D Gaussian Splatting via Finger‐based VR Interface
Advanced Intelligent Systems, EarlyView.This study introduces a human‐in‐the‐loop segmentation framework for 3D Gaussian Splatting that integrates real‐time optimization with intuitive VR‐based finger prompting. Compared with existing automatic, learning‐based methods, it achieves significantly higher accuracy and reduced segmentation time.

Adaptive Macroscopic Ensemble Allocation for Robot Teams Monitoring Spatiotemporal Processes
Advanced Intelligent Systems, EarlyView.We propose an online, environment feedback‐driven macroscopic ensemble approach to adapt robot team task allocation in spatiotemporal environments by controlling robot populations rather than assigning individual robots, all while maintaining robust team performance even for small teams. Our simulation and experimental results show better or comparable
