Study on the Effects and Mechanisms of Urea on Predation Behavior of Farmland Spiders

Most existing studies focus on field population dynamics and community structure, with scarce reporting on underlying mechanisms. This project, titled "Study on the Effects and Mechanisms of Urea on Predation Behavior of Farmland Spiders," integrates multidisciplinary theories and employs a combined approach of field investigations and laboratory experiments.

It aims to Reveal the predatory strategies of dominant spider populations under chronic urea stress in agricultural ecosystems; to analyze the effects and mechanisms of chronic urea stress on predation-related metabolic, detoxification, and neuromodulation functions in dominant spider species from biological, physiological, cytomorphological, and multi-omics perspectives; to elucidate the comprehensive regulatory role and mechanisms of spider gut microbiota in mediating predation function responses to urea stress.Collectively, this research will clarify the impact and mechanisms of urea on the predation function of farmland spiders, providing a theoretical foundation and practical support for optimizing urea application in agricultural production and achieving the optimal comprehensive effects on spider predation services.
