Abstract:
Objective To explore the relationship between the distribution characteristics and the habitat factors of the invasive B. straminea in South China. Methods From October 2016 to August 2017, the breeding condition and habitat factors of B. straminea were investigated in the rivers of Shenzhen and its adjacent areas in the dry season, normal season and wet reason. The generalized additive model (GAM) was used to study the main habitat factors affecting the distribution density of B. straminea. Results The distribution characteristics of B. straminea showed obvious aggregation and unevenness in space. In terms of time, the density of snails was the highest in the dry season, followed by the normal water season and the least in the wet season. The GAM model analysis showed that the main habitat factors affecting the distribution density of B. straminea were water depth, water temperature, flow velocity, dissolved oxygen, and total phosphorus. When the flow velocity and water temperature were 0.25 m / s and 26 °C, respectively, the largest distribution density of snails might appear. The distribution density of B. straminea was positively correlated with dissolved oxygen and total phosphorus. Conclusion B. straminea is suitable to live in the water environment with poor water quality. In the future, the monitoring should be strengthened to provide reference for the prevention and control of the spread of the snails.
