Upwash exploitation and downwash avoidance by flap phasing in ibis formation flight (2014)
Journal Article
Portugal, S. J., Hubel, T. Y., Fritz, J., Heese, S., Trobe, D., Voelkl, B., …Usherwood, J. R. (2014). Upwash exploitation and downwash avoidance by flap phasing in ibis formation flight. Nature, 505(7483), 399-+. https://doi.org/10.1038/nature12939

Many species travel in highly organized groups. The most quoted function of these configurations is to reduce energy expenditure and enhance locomotor performance of individuals in the assemblage. The distinctive V formation of bird flocks has long i... Read More about Upwash exploitation and downwash avoidance by flap phasing in ibis formation flight.

Vaulting mechanics successfully predict decrease in walk-run transition speed with incline (2013)
Journal Article
Hubel, T. Y., & Usherwood, J. R. (2013). Vaulting mechanics successfully predict decrease in walk-run transition speed with incline. Biology Letters, 9(2), https://doi.org/10.1098/rsbl.2012.1121

There is an ongoing debate about the reasons underlying gait transition in terrestrial locomotion. In bipedal locomotion, the ‘compass gait’, a reductionist model of inverted pendulum walking, predicts the boundaries of speed and step length within w...
