Background: Research on genetic diversity based on mitochondrial DNA of giant pandas mainly focused on a single marker or a few genes.
Objective: To provide a more comprehensive assessment of the genetic diversity on giant pandas based on 13 mitochondrial protein coding genes.
Methods: We assembled 13 protein coding genes in the mitochondrial genome of the giant panda based on the whole genome sequencing data, including ND1, ND2, COX1, COX2, ATP8, ATP6, COX3, ND3, ND4L, ND4, ND5, ND6 and Cyt b.
Results: We successfully obtained long sequence of 11,416 base pairs with all 13 genes for 110 giant panda individual, accounting for 67.93% in length of the mitochondrial reference genome. Haplotype diversity was 0.9518 ± 0.009 and nucleotide diversity (π) was 0.00157 ± 0.00014. We detected three new haplotypes, including GPC10 and GPC21 for the CR sequence and GPB12 for the Cyt b gene.
Conclusion: These multi-gene sequences provided more genetic variable information to compare captive and wild giant panda population.

Human Footprint and Forest Disturbance Reduce Space Use of Brown Bears (Ursus arctos) Across Europe.

Three-quarters of the planet's land surface has been altered by humans, with consequences for animal ecology, movements and related ecosystem functioning. Species often occupy wide geographical ranges with contrasting human disturbance and environmental conditions, yet, limited data availability across species' ranges has constrained our understanding of how human pressure and resource availability jointly shape intraspecific variation of animal space use. Leveraging a unique dataset of 758 annual GPS movement trajectories from 375 brown bears (Ursus arctos) across the species' range in Europe, we investigated the effects of human pressure (i.

Here, we evaluate if ATPase activity of resting skeletal muscle myosin can contribute to this energy sparing. By analyzing single muscle fibers taken from the same bears, either during hibernation or in summer, we find that fibers from hibernating bears have a mild decline in force production and a significant reduction in ATPase activity.

Background: Babesia is a tick-borne protozoan blood parasite that can cause hemolytic anemia, thrombocytopenia, lethargy and splenomegaly in giant pandas.
Methods: We evaluated the efficacy and safety profile of a therapeutic regimen combining atovaquone and zithromycin in the context of babesiosis in giant pandas that have been naturally infected. The examined pandas underwent clinical and laboratory analyses, including hematology, biochemistry and thyroid hormone profiles.

Red pandas () are endangered with extinction due to deforestation and habitat fragmentation. Reported causes of unexpected death in managed red pandas include kidney, liver, gastrointestinal, and cardiac disease. A previously undetailed syndrome, red panda peracute mortality syndrome, may be emerging, as red pandas have died unexpectedly, with no clear cause of death identified at necropsy.

Andean bears (Tremarctos ornatus) forage extensively on bromeliads (Puya spp.) across their range, although their selectivity for bromeliads is less understood. We report on foraging activity by Andean bears on two species of bromeliad, Puya leptostachya and Puya membranacea, in high elevation puna grasslands (3499-3806 m.
