Spider dietary breadth and overlap increased with imperviousness, suggesting that prey and spiders are concentrating in vacant lots in these landscapes. Higher vegetation biomass, which results from reduced mowing frequency, was associated with increased dietary breadth and shared prey between spiders.

Experimental study on impact failure characteristics of deep circular roadway
In order to study the impact failure characteristics of deep circular roadway under the condition of disturbance load, based on the self-developed multi-functional physical simulation test system of rock burst, the impact failure test of circular roadway was carried out for large-scale rock-like materials.
