The most commonly used density constants (~1.06 g/cm3) have been derived from experimental studies of tissue samples collected predominantly from the lower limbs of several model taxa, which have included cats, dogs, rabbits and guinea pigs. However, the generalized application of this constant to broader analyses of mammalian myology assumes: that muscle density is consistent regardless of 1) anatomical region and 2) ontogenetic age of the specimen. To investigate these assumptions, we measured the density of whole muscles from specific anatomical regions (head: masseter, digastric, quadratus labii; forearm: pronator teres, extensor carpi radialis longus; leg: gastrocnemius, soleus, plantaris; trunk: psoas minor) from three different age cohorts (3 weeks, 8 months and 2 years) of 48 (n= 12, 24, 12 respectively) New Zealand white rabbits (Oryctolagus cuniculus). The data were analyzed for statistically significant differences between muscle types and specimen ages using Tukey HSD tests. Our findings demonstrate no regional differences in muscle density within the 3‐week‐old cohort. Contrastingly, within the older age cohorts, statisitically significant differences in muscle density were observed between anatomical regions. The plantaris was consistently the most dense muscle studied (1.07 g/cm3) while quadratus labii was the least dense (1.04 g/cm3). The most prominent region specific variation was seen within the triceps surae, with soleus being consistently and significantly less dense than gastrocnemius and plantaris in the older age cohorts. These data suggest that age and region dependent measurements of muscle density may increase the validity of PCSA estimations.}, journal={FASEB JOURNAL}, author={Leonard, Kaitlyn and Worden, Nikole and Dickinson, Edwin and Hartstone-Rose, Adam}, year={2020}, month={Apr} } @article{boettcher_dickinson_leonard_herrel_hartstone-rose_2020, title={Anatomical reorganization within the hand and forelimb of Perodicticus potto}, volume={34}, ISSN={["1530-6860"]}, DOI={10.1096/fasebj.2020.34.s1.06629}, abstractNote={Historical behavioral accounts note extraordinarily high grip strength in Perodicticus potto. Anatomical analysis of the potto’s hand and forelimb reveal several specializations that may facilitate this enhanced gripping ability, including a specialized vascular bundle (the retia mirabilia) within the wrist, a hyper‐abducted pollex, and a highly reduced second digit. The myological correlates of grip strength (i.e., the contractile potential of the hand and wrist musculature) of P. potto, however, have yet to be quantitatively evaluated. The current study contrasts the myology of the hand and forearm muscles within P. potto to a series of closely‐related strepsirrhines (Nycticebus coucang, Otolemur crassicaudatus, Hapalemur griseus, and Eulemur mongoz), as well as comparing the forearm musculature to a broader (n= 41) primate sample. Despite reports of the potto’s high grip strength, our findings demonstrate relatively below‐average force capacity (relatively low physiological cross‐sectional area) within the digital flexors of this species, which suggests that the gripping ability of this species may be less extraordinary than previously hypothesized. In addition to this observation, we report a number of unusual myological features within the potto, including the largest brachioradialis (an elbow flexor) of any taxon within our sample. Even more surprisingly, we identified an independent extensor indicis within P. potto, despite the vestigial nature of the second digit, and the absence of this muscle within ~25% of other taxa within our sample ‐ all of which possessed a more substantial second digit than the potto. These data underscore the curious nature of the potto’s antebrachial musculature, but suggest that adaptations within the potto’s forelimb may be more related to maximizing endurance grip potential than towards increasing myological force.}, journal={FASEB JOURNAL}, author={Boettcher, Marissa and Dickinson, Edwin and Leonard, Kaitlyn and Herrel, Anthony and Hartstone-Rose, Adam}, year={2020}, month={Apr} } @book{boettcher_leonard_herrel_hartstone-rose_2020, title={Evolution, Ecology and Conservation of Lorises and Pottos}, volume={86}, ISBN={["978-1-108-45288-5"]}, ISSN={["1746-2266"]}, DOI={10.1017/9781108676526}, abstractNote={Book summary page views Book summary page views help Close Book summary page views help Book summary views reflect the number of visits to the book and chapter landing pages.
