Ecology, 2021
AbstractOrganismal locomotion mediates ecological interactions and shapes community dynamics. Locomotion is constrained by intrinsic and environmental factors and integrating these factors should clarify how locomotion affects ecology across scales. We extended general theory based on metabolic scaling and biomechanics to predict the scaling of five ...

ABSTRACTMost species of caterpillar move around by inching or crawling. Their ability to navigate in branching three‐dimensional structures makes them particularly interesting biomechanical subjects. The mechanism of inching has not been investigated in detail, but crawling is now well understood from studies on caterpillar neural activity, dynamics ...

Abstract Pressures previously measured on the body surface of swimming bluefish were resolved into their backward vectorial components to allow calculation of profile drag. It was 0.18 kg at a speed of 1.8 m/sec. Tangential drag was calculated as if for a thin plate of an area equal to that of the fish. It was 0.08 kg at 1.8 m/sec.

By considering the general energy balance between the energy of muscular contraction in the extremities, kinetic energy imparted to the animal and the energy lost in the lifting of the center of gravity and in the possible muscular viscosity, an expression is derived for the speed of an animal in terms of the constant which determine its shape and ...

AbstractResearch into the autonomous motion of artificial nano‐ and microscale objects provides basic principles to explore possible applications, such as self‐assembly of superstructures, roving sensors, and drug delivery. Although the systems described have unique propulsion mechanisms, motility in each case is made possible by the conversion of ...

The hypothesis that Pygmies may differ from Caucasians in some aspects of the mechanics of locomotion was tested. A total of 13 Pygmies and 7 Caucasians were asked to walk and run on a treadmill at 4-12 km.h-1. Simultaneous metabolic measurements and three-dimensional motion analysis were performed allowing the energy expenditure and the mechanical ...

ABSTRACT The form and frequency of the waves passing down the bodies of small free-living nematodes (Panagrellus, Rhabditis and Turbatrix) depend on the nature of the external medium. Observations of animals moving in such media as syrup, agar gels, and dense suspensions of particles suggest that the relationship between the speed of ...
