Investigating the Distribution and Occupancy of Otter Species across Human-modified Landscapes in Sabah, Malaysia.

A study on the occupancy of otters in streams across land-use gradient, within four habitat treatments: logged forest (LF), heavily degraded forest (HDF), riparian reserves within oil palm plantation (RR), and oil palm plantation (ROP).
