R-package ‘BaBA’

Barrier Behaviour Analysis (BaBA) is a spatial- and temporal-explicit method to identify and classify barrier behaviors, fence behaviors in our case, based on GPS tracking data and linear spatial features. Barrier behaviors can be used to examine the permeability of barriers for animal movement.

The six kinds of behaviors that BaBA classifies are: bounce, trace, back-n-forth, average movement, quick cross, and trapped.

Tibetan antelope migration map

Published in the Atlas of Ungulate Migration, the Hoh Xil Tibetan antelope migration map is one of the most detailed maps that exists for the species. Together with the Convention on the Conservation of Migratory Species of Wild Animals (CMS) and Global Initiative on Ungulate Migration (GIUM), we also published the fact sheet on Tibetan antelope migration.
