yz Nice to finally have you here . I've shared some of your forelimb comparisons . Looking forward to more of these comparisons from you

Forelimb Comparison Between the polar bear and wolverine : Studies used for the above comparison:[/u] academic.oup.com/zoolinnean/article/142/1/91/2691231www.researchgate.net/publication/298056854_Sexual_selection_on_skeletal_shape_in_Carnivorawww.researchgate.net/publication/230843015_Postcranial_morphology_and_the_locomotor_habits_of_living_and_extinct_carnivoreswww.researchgate.net/publication/20806549_Differential_scaling_of_the_long_bones_in_the_terrestrial_carnivora_and_other_mammalswww.researchgate.net/publication/280973278_Carnivoran_postcranial_adaptations_and_their_relationships_to_climatWolverines can be quite strong, powerful animals for their size. Yet, most ratios point out to the Polar Bear having stronger shoulders, thicker Forelimb bones, larger epicondyles,trochleas,olecrana, more stability and the ability to produce more force based on its Forelimb Proportions even at similar size while the mustelid only has relatively bigger paws. Overall, Ursus Maritimus was stronger, more muscular and more robust than Gulo Gulo. Therefore, if we factor in the huge size gap, there'll be nothing that the Wolverine can do against a giant Polar Bear in a fight.

bears >>>>> mustelids. Fact! The polar bear is much larger and stronger than the wolverine to begin with. Even a sun bear is too much for the wolverine and honey badger to begin with. Bears have a weight advantage to begin with. Don’t forget the square cube law.

Differential expression of myosin heavy chain isoforms type II in skeletal muscles of polar and black bears. TLDR The results suggest that in bears, there is greater diversity in MHC isoforms II, being expressed in selected fast contracting skeletal muscles in response to variety of environments, weight bearing and locomotion. Abstract In this study, the pattern of myosin heavy chain (MHC) isoforms expression in skeletal muscles of the trunk, forelimb and hindlimb in Polar Bear (PB) Ursus maritimus; American Black Bear (AmBB), Ursus americanus and Asian Black Bear (AsBB), Ursus thibetanus was analysed by immunohistochemistry and SDS‐PAGE. Results showed that slow (MHC‐I) and fast (MHC‐II) isoforms exist in muscles of bears. Type II fibres were classified further into Type IIa and IIx in PB but not in AsBB and AmBB. The distribution of Type I and Type II fibres in the trunk, forelimb and hindlimb varied based on muscle type and animal species. The proportions of Type I fibres formed approximately one‐third of muscle composition in PB (trunk, 32.0%; forelimb, 34.7%; hindlimb, 34.5%) and a half in both AsBB and AmBB whereas Type IIa and IIx formed approximately two‐third in PB (trunk, 68.0%; forelimb, 65.3%; hindlimb, 65.5%) and a half of Type II in both AmBB and AsBB. PB is a good swimmer, lives in Arctic Ocean on slippery ice catching aquatic mammals such as seals and is larger in size compared to the medium sized AmBB (living in forest) and AsBB (arboreal). The results suggest that in bears, there is greater diversity in MHC isoforms II, being expressed in selected fast contracting skeletal muscles in response to variety of environments, weight bearing and locomotion. www.semanticscholar.org/paper/Differential-expression-of-myosin-heavy-chain-type-Kawata-Luziga/18c12a9e670d3b5393f4d7f096654e7d78732a71
