    Biomechanics Penguin waddling is not wasteful (2000)
    [s.l.] : Macmillan Magazines Ltd.
    Nature 408 (2000), S. 929-929 
    Details

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] Penguins use twice as much metabolic energy as other terrestrial animals of a similar mass to walk a given distance, which was thought to be because side-to-side waddling requires excessive work. Here we show that waddling actually conserves mechanical energy and suggest instead that ...

    Biomechanics Are fast-moving elephants really running? (2003)
    [s.l.] : Nature Publishing Group
    Nature 422 (2003), S. 493-494 
    Details
    ISSN: 1476-4687

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] It is generally thought that elephants do not run, but there is confusion about how fast they can move across open terrain and what gait they use at top speed. Here we use video analysis to show that Asian elephants (Elephas maximus L.) can move at surprisingly high speeds of up to 6.8 m ...

    Energetics of running: a new perspective (1990)
    [s.l.] : Nature Publishing Group
    Nature 346 (1990), S. 265-267 
    Details

    Notes: [Auszug] In testing the above hypothesis across both speed and size, we made three assumptions. First, we assumed that most of the force exerted by the muscles acts to oppose gravity. This seems reasonable as force platform measurements on a variety of running animals have shown that the vertical force is ...
