Method & Application
We will apply environmental DNA and macrobarcoding technology
- Assess the composition, changes, mechanisms of biodiversity formation, and ecological impacts of human activities in aquatic ecosystems.
- Explore the nutritional cascade regulation of food webs by top predators and the coexistence mechanism of carnivores.

Environmental DNA captures native and non-native fish community variations across the lentic and lotic systems of a megacity
This study conducted a large-scale investigation on fish communities in different standing and flowing water systems in Beijing using environmental DNA, revealing the compositional differences between native and non-native fish species in different water body types.
The results indicate that water quality conditions have a more significant impact on the diversity of native fish, while exotic fish are more prone to expand in some systems as urban disturbance intensifies.
Metropolitan pressures: Significant biodiversity declines and strong filtering of functional traits in fish assemblages
This study indicates that as urban disturbance intensifies, both the taxonomic and functional diversity of fish communities decrease significantly, and the composition of the communities tends to simplify.
Meanwhile, water pollution can exert a significant selection effect on the functional traits of fish, indicating that urban water ecological protection should not only focus on the number of species, but also on changes in functional structure.
Against the backdrop of severe threats and continuous loss of global biodiversity, our research group utilizesmolecular biology methods to assess the composition of biodiversity, changes in community structure, and their response patterns to environmental and human disturbances.
