- Skeletal stiffening in an amphibious fish out of water is a response to increased body weight
Highlighted Article: Did weight responsiveness evolve during the tetrapod invasion of land or is it ubiquitous among vertebrates? Skeletal stiffening in amphibious fish out of water supports the latter hypothesis.
- A peculiar mechanism of bite-force enhancement in lungless salamanders revealed by a new geometric method for modeling muscle moments
Summary: Desmognathine salamanders achieve a strong bite with a unique ligamentous mechanism that amplifies muscle force.
- Mechanical properties of sediment determine burrowing success and influence distribution of two lugworm species
Summary: Field-based measurements link distribution of two ecosystem engineer lugworm species with the mechanical properties of the sediment, their differential burrowing success and morphological features.
- Performance, morphology and control of power-amplified mandibles in the trap-jaw ant Myrmoteras (Hymenoptera: Formicidae)
Summary: The kinematics, anatomy and power-amplification mechanism for trap-jaw ants in the genus Myrmoteras, one of four convergent ant lineages with spring-loaded mandibles, are described.
- Rib kinematics during lung ventilation in the American alligator (Alligator mississippiensis): an XROMM analysis
Summary: Using XROMM to test how well joint anatomy predicts rib motion during breathing in crocodylians, our best living model for the earliest archosaurs.
- Changes in mechanical work during neural adaptation to asymmetric locomotion
Summary: Minimizing mechanical work performed by the legs may drive locomotor adaptation, with wide relevance for the control of legged locomotion and motor learning in novel environments.
- Hindlimb muscle function in turtles: is novel skeletal design correlated with novel muscle function?
Summary: Novel muscle arrangements and leverage patterns associated with derived fusion of the pelvis to the shell in pleurodire turtles are associated with several novel muscle activity patterns in this lineage.
- Ontogeny of bite force in a validated biomechanical model of the American alligator
Summary: A high-fidelity 3D computational model of alligator bite force that can be used for inferring feeding behavior in fossils.
- Muscle–tendon mechanics explain unexpected effects of exoskeleton assistance on metabolic rate during walking
Summary: Lower-limb exoskeletons often produce odd adaptations in humans. Muscle-level mechanics and energetics, estimated in data-driven simulations of exoskeleton-assisted walking, can explain why.
- Hearing on the fly: the effects of wing position on noctuid moth hearing
Summary: Noctuid moth wing position affects neural hearing sensitivity. No significant differences in eardrum movement occur; therefore, differences are hypothesized to be due to internal factors such as muscle tension.
