    Burst muscle performance predicts the speed, acceleration, and turning performance of Anna’s hummingbirds

    Paolo S Segre, Roslyn Dakin ... Douglas L Altshuler
    Maneuverability is thought to be limited by either intrinsic constraints or physiological capacity, and automated tracking of flying hummingbirds reveals that muscle capacity explains much of the variation in their flight trajectories.

    Mass enhances speed but diminishes turn capacity in terrestrial pursuit predators

    Rory P Wilson, Iwan W Griffiths ... David M Scantlebury
    Increased mass enhances speed but compromises turning capacity in pursuit predators; this has widespread ramifications for the best strategies for predators and prey during chases according to their relative masses.

    Energetic and physical limitations on the breaching performance of large whales

    Paolo S Segre, Jean Potvin ... Jeremy A Goldbogen
    Muscle power-generating capabilities, and not energetic limitations, limit the breaching abilities of the largest whales.

    Wind prevents cliff-breeding birds from accessing nests through loss of flight control

    Emily Shepard, Emma-Louise Cole ... Andrew Ross
    Even moderate winds cause auks to abort landing attempts at nest-sites, and as a result, wind characteristics may affect where these, and other seabirds, choose to breed.

    Spinosaurus is not an aquatic dinosaur

    Paul C Sereno, Nathan Myhrvold ... Lauren L Conroy
    A digital flesh model of the sail-backed dinosaur Spinosaurus was tested and performed very poorly in water, favoring the view of this dinosaur as a two-legged, wading ambush predator of large fish in shallow waterways and not an aquatic dinosaur.

    Convergent evolution in silico reveals shape and dynamic principles of directed locomotion

    Tapered whiskers are required for active tactile sensation

    Samuel Andrew Hires, Lorenz Pammer ... David Golomb
    The tapered, conical shape of rodent whiskers is essential for sensor mobility in constrained spaces and feature extraction from textured surfaces.

    Variability in locomotor dynamics reveals the critical role of feedback in task control

    Ismail Uyanik, Shahin Sefati ... Noah J Cowan
    Animals rely on sensory feedback rather than the precise tuning in the nervous system to achieve robust behavioral performances.

    The roles of vision and antennal mechanoreception in hawkmoth flight control

    Ajinkya Dahake, Anna L Stöckl ... Almut Kelber
    Mechanosensors in the antennae of hawkmoths provide rapid sensory feedback for the control of fast flight manoeuvres, which acts in parallel to visual information.

    Wings and halteres act as coupled dual oscillators in flies

    Tanvi Deora, Siddharth S Sane, Sanjay P Sane
    Flight system of flies is driven by wings and mechanosensory halteres that operate as independently driven but coupled oscillators, thereby imparting robustness against wing or thorax damage.
