Ontogenetic scaling of foot musculoskeletal anatomy in elephants
Journal Article
Miller, C. E., Basu, C. K., Fritsch, G., Hildebrandt, T., & Hutchinson, J. R. Ontogenetic scaling of foot musculoskeletal anatomy in elephants. https://doi.org/10.1098/rsif.2007.1220

This study quantifies the shape change in elephant manus and pes anatomy with increasing body mass, using computed tomographic scanning. Most manus and pes bones, and manus tendons, maintain their shape, or become more gracile, through ontogeny. Cont... Read More about Ontogenetic scaling of foot musculoskeletal anatomy in elephants.

The movements of limb segments and joints during locomotion in African and Asian elephants
Journal Article
Ren, L., Butler, M., Miller, C. E., Paxton, H. P., Schwerda, D., Fischer, M. S., & Hutchinson, J. R. The movements of limb segments and joints during locomotion in African and Asian elephants. Journal of Experimental Biology, 211(17), 2735-2751. https://doi.org/10.1242/jeb.018820

As the largest extant terrestrial animals, elephants do not trot or gallop but can move smoothly to faster speeds without markedly changing their kinematics, yet with a shift from vaulting to bouncing kinetics. To understand this unusual mechanism, w... Read More about The movements of limb segments and joints during locomotion in African and Asian elephants.

The three-dimensional locomotor dynamics of African (Loxodonta africana) and Asian (Elephas maximus) elephants reveal a smooth gait transition at moderate speed
Journal Article
Ren, L., & Hutchinson, J. R. The three-dimensional locomotor dynamics of African (Loxodonta africana) and Asian (Elephas maximus) elephants reveal a smooth gait transition at moderate speed. https://doi.org/10.1098/rsif.2007.1095

We examined whether elephants shift to using bouncing (i.e. running) mechanics at any speed. To do this, we measured the three-dimensional centre of mass (CM) motions and torso rotations of African and Asian elephants using a novel multisensor method...

Limb kinematics, kinetics and muscle dynamics during the sit-to-stand transition in greyhounds
Journal Article
Ellis, R. G., Rankin, J. W., & Hutchinson, J. R. (in press). Limb kinematics, kinetics and muscle dynamics during the sit-to-stand transition in greyhounds. Frontiers in Bioengineering and Biotechnology, https://doi.org/10.3389/fbioe.2018.00162

Standing up from a prone position is a critical daily activity for animals: failing to do so effectively may cause an injurious fall or increase predation susceptibility. This sit-to-stand behaviour (StS) is biomechanically interesting because it nec... Read More about Limb kinematics, kinetics and muscle dynamics during the sit-to-stand transition in greyhounds.

Energy allocation and behaviour in the growing broiler chicken
Journal Article
Tickle, P. G., Hutchinson, J. R., & Codd, J. R. (in press). Energy allocation and behaviour in the growing broiler chicken. https://doi.org/10.1038/s41598-018-22604-2

Broiler chickens are increasingly at the forefront of global meat production but the consequences of fast growth and selection for an increase in body mass on bird health are an ongoing concern for industry and consumers. To better understand the imp... Read More about Energy allocation and behaviour in the growing broiler chicken.

Big cat, small cat: Reconstructing body size evolution in living and extinct Felidae
Journal Article
Cuff, A. R., Randau, M., Head, J., Hutchinson, J. R., Pierce, S. E., & Goswami, A. (in press). Big cat, small cat: Reconstructing body size evolution in living and extinct Felidae. Journal of Evolutionary Biology, 28(8), 1516-1525. https://doi.org/10.1111/jeb.12671

The evolution of body mass is a fundamental topic in evolutionary biology, because it is closely linked to manifold life history and ecological traits and is readily estimable for many extinct taxa. In this study, we examine patterns of body mass evo... Read More about Big cat, small cat: Reconstructing body size evolution in living and extinct Felidae.
