Validation of grizzly bear hair hormone profiles as a tool to monitor population demographics

The Journal of Wildlife Management, Volume 90, Issue 2, February 2026.
We measured 16 steroid and thyroid hormone concentrations in grizzly bear hair to predict sex, age class, and reproductive status. Models were highly accurate when predicting sex and age class and showed promise for assessing reproductive status. Results illustrate the potential for hair hormone profiles as non‐invasive population monitoring tools ...

Cloning and characterization of giant panda (Ailuropoda melanoleuca) IL-18 binding protein. [PDF]

Res Vet Sci, 2016
The giant panda (Ailuropoda melanoleuca) is an endangered species. Interleukin-18 (IL-18) plays an important role in the innate and adaptive immune responses by inducing IFN-γ. IL-18 has been implicated in the pathogenesis of various diseases. IL-18 binding protein (IL-18BP) is an intrinsic inhibitor of IL-18 that possesses higher affinity to IL-18. In

Relationship Between Testosterone and Movement Patterns in Male Asian Black Bear (Ursus thibetanus)

Ecology and Evolution, Volume 16, Issue 1, January 2026.
Comparisons of mean fecal testosterone metabolite concentrations (mFTM) and behavioral variables between the breeding (May–July) and post‐breeding (August–November) seasons. The asterisks indicate significant differences. ABSTRACT In male mammals, reproduction and reproductive behavior are strongly influenced by testosterone. While some species exhibit

Earliest giant panda false thumb suggests conflicting demands for locomotion and feeding

Scientific Reports, 2022
Of the many peculiarities that enable the giant panda (Ailuropoda melanoleuca), a member of the order Carnivora, to adapt to life as a dedicated bamboo feeder, its extra “thumb” is arguably the most celebrated yet enigmatic.

An Energetic Tradeoff Best Explains Parturition Timing in Grizzly Bears

Ecology and Evolution, Volume 16, Issue 1, January 2026.
Capitalizing on latitudinal denning‐chronology variation among four grizzly bear populations in interior North America, and using grizzly bear parturition dates (27 Dec–28 Feb) previously predicted from anomalous daily motion counts, we found evidence supporting the hypothesis that birth is optimally timed relative to den exit to balance an energetic ...
