Telemetry research on elusive wildlife: A synthesis of studies on giant pandas.

Telemetry studies that track animals through space and time can lead to advances in scientific understanding that are vital in conservation efforts. For example, telemetry studies of the giant panda (Ailuropoda melanoleuca) have shed light on many aspects of panda biology, but small sample sizes in each separate study make it difficult to draw broad conclusions. To overcome this problem we conducted the first synthesis of all 5 panda telemetry studies conducted to date. Using these data we investigated patterns in 6 main topics: home range, space-use interactions, core areas, movement patterns, seasonal migration and natal dispersal. We found that panda home range sizes do not vary between 2 main mountain ranges (Qionglai and Qinling), as was previously believed. Our results also suggest that female pandas increase their movement in the mating season: a behavior typically attributed only to males. We found and summarized telemetry and genetic evidence for female natal dispersal in the giant panda. Our synthesis highlights the need for additional research relating panda behavior to human disturbance factors, and can aid future studies on giant pandas as well as other species.
