Table 2 Average (± SD) two-dimensional (minimum convex polygon (MCP) and 2D Kernel Utilization Distribution (KUD) and three-dimensional (3D KUD) activity areas for brown treesnakes (Boiga irregularis) in the Habitat Management Unit (HMU) during high prey availability.

From: Invasive brown treesnakes (Boiga irregularis) move short distances and have small activity areas in a high prey environment
