Dickinson, E., Manzo, M., Davis, C. E., Kolli, S., Schwenk, A., Carter, A., … Hartstone-Rose, A. (2023, December 8). ANATOMICAL RECORD-ADVANCES IN INTEGRATIVE ANATOMY AND EVOLUTIONARY BIOLOGY.
author keywords: anatomy; DiceCT; feeding; lemurs; PCSA
TL;DR:

Effects of freezing and short-term fixation on muscle mass, volume, and density
Leonard, K. C., Worden, N., Boettcher, M. L., Dickinson, E., & Hartstone-Rose, A. (2021, May 6). ANATOMICAL RECORD-ADVANCES IN INTEGRATIVE ANATOMY AND EVOLUTIONARY BIOLOGY, Vol. 5.
author keywords: correction; ethanol; formalin; preparation
MeSH headings : Animals; Ethanol; Formaldehyde; Freezing; Muscles; Rabbits; Tissue Fixation
TL;DR:
Although freezing may have less of an effect on the gross morphometric characteristics of the musculature than ethanol storage, slow freezing damages muscle microanatomy, and therefore, faster freezing and other modes of preservation such as formalin fixation and ethanol storage may be preferable.

Functional and ecological correlates of the primate jaw abductors
Dickinson, E., Pastor, F., Santana, S. E., & Hartstone-Rose, A. (2021, September 24). ANATOMICAL RECORD-ADVANCES IN INTEGRATIVE ANATOMY AND EVOLUTIONARY BIOLOGY, Vol. 305.
author keywords: diet; digastric; lateral pterygoid; muscle architecture; social ecology
MeSH headings : Animals; Diet; Dogs; Female; Jaw / physiology; Male; Masticatory Muscles / physiology; Movement; Primates

Anatomical reorganization within the hand and forelimb of <it>Perodicticus potto</it>
Boettcher, M., Dickinson, E., Leonard, K., Herrel, A., & Hartstone-Rose, A. (2020, April). FASEB JOURNAL, Vol. 34.
TL;DR:
Despite reports of the potto’s high grip strength, the 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 ofThis species may be less extraordinary than previously hypothesized.

Intraspecific and intrafamilial variation in primate forearm muscle architecture
Hartstone-Rose, A., Boettcher, M., Seelye, J., Worden, N., & Dickinson, E. (2020, April). FASEB JOURNAL, Vol. 34.
TL;DR:
Assessing both qualitative (presence/absence of specific muscles) and quantitative (physiological cross‐sectional area, fascicle length and muscle mass) differences in forearm muscle architecture of larger intraspecific and samples with greater coverage of specific primate families than had been included in previous work found that there is great variation in both the extent of separation and fusion of flexor digitorum superficialis and profundus in most species of callitrichids and Saimiri.
