Data from: Hummingbirds control turning velocity using body orientation and turning radius using asymmetrical wingbeat kinematics
Turning in flight requires reorientation of force, which birds, bats and insects accomplish either by shifting body position and total force in concert or by using left–right asymmetries in wingbeat kinematics. Although both mechanisms have been observed in multiple species, it is currently unknown how each is used to control changes in trajectory. We addressed this problem by measuring body and wingbeat kinematics as hummingbirds tracked a revolving feeder, and estimating aerodynamic forces using a quasi-steady model. During arcing turns, hummingbirds symmetrically banked the stroke plane of both wings, and the body, into turns, supporting a body-dependent mechanism. However, several wingbeat asymmetries were present during turning, including a higher and flatter outer wingtip path and a lower more deviated inner wingtip path. A quasi-steady analysis of arcing turns performed with different trajectories revealed that changes in radius were associated with asymmetrical kinematics and forces, and changes in velocity were associated with symmetrical kinematics and forces. Collectively, our results indicate that both body-dependent and -independent force orientation mechanisms are available to hummingbirds, and that these kinematic strategies are used to meet the separate aerodynamic challenges posed by changes in velocity and turning radius.
Data from: Intermediate kinematics produce inferior feeding performance in a classic case of natural hybridization
Selection on naturally-occurring hybrid individuals is a key component of speciation theory, but few studies examine the functional basis of hybrid performance. We examine the functional consequences of hybridization in nature using the freshwater sunfishes (Centrarchidae), where natural hybrids have been studied for over a century and a half. We examined bluegill (Lepomis macrochirus), green sunfish (Lepomis cyanellus), and their naturally-occurring hybrid using prey capture kinematics and morphology to parameterize suction feeding simulations on divergent parental resources. Hybrid individuals exhibited intermediate kinematics between the two parental species. However, performance assays indicated that hybrids display performance most similar to the worse-performing species for a given parental resource. Our results show that intermediate hybrid phenotypes can be impaired by a less than intermediate performance and hence suffer a larger loss in fitness than could be inferred from morphology alone.

Supplemental data for: Three-dimensional kinematics of euchelicerate limbs uncover functional specialisation in eurypterid appendages
<p>Sea scorpions (Eurypterida; Euchelicerata) explored the extreme limits of the aquatic euchelicerate body plan. Indeed, the group contains the largest known marine euarthropods. Inferences on eurypterid life modes—in particular walking and eating—are commonly made by comparing the group to horseshoe crabs (Xiphosura; Euchelicerata). However, no models have been presented to test these <span>hypotheses</span>. Here, we reconstruct prosomal appendages of two exceptionally well-preserved eurypterids <i>Eurypterus tetragonophthalmus</i> and <i>Pentecopterus decorahensis </i>and kinematically model the flexure and extension of these appendages in 3D. We compare these models to 3D kinematic models of <i>Limulus polyphemus</i> prosomal appendages. This comparison highlights that the examined eurypterid prosomal appendages could not have effectively moved prey items to the gnathal edges, and therefore would not have emulated the motion of a <i>L. polyphemus</i> walking leg. It seems that these eurypterid appendages were primarily used to walk or grab prey and other appendages would have moved prey for mastication. Such 3D kinematic modelling highlights how eurypterid appendage morphologies placed substantial limits on their function, suggesting a high degree of specialisation, especially when compared to horseshoe crabs. 3D kinematic modelling of these extinct groups also presents an innovative approach to understanding the position of these animals within their respective paleoecosystems.</p>
