Data from: Flight reconstruction of two European enantiornithines (Aves, Pygostylia) and the achievement of bounding flight in Early Cretaceous birds
- 负责人：
- DOI：
- doi:10.5061/dryad.rn420
- 摘要：
- and intermittent bounds, but not through facultative glides. Aerodynamic models indicate that the power margins of these birds were sufficient to sustain bounding
Size, Composition, and Source Profiles of Inhalable Bioaerosols from Colorado Dairies
- 负责人：
- DOI：
- doi:10.6084/m9.figshare.4239830
- 摘要：
- of chemical and biological constituents(bioaerosols) with aerodynamic diameters consistent with the inhalablefraction. Due to sampling and analytic

Data from: Ontogeny of aerial righting and wing flapping in juvenile birds
- 负责人：
- DOI：
- doi:10.5061/dryad.s6k44
- 摘要：
- transitioned to bilaterally symmetric flapping that yielded aerial righting via nose-down pitch, along with substantial increases in vertical force prod
Data from: A songbird compensates for wing molt during escape flights by reducing the molt gap and increasing angle-of-attack
- 负责人：
- DOI：
- doi:10.5061/dryad.g28t010
- 摘要：
- , but flight speed and net aerodynamic force production did not differ between the two groups. We found that in manipulated birds, the size of the gap was reduced
Data from: Barb geometry of asymmetrical feathers reveals a transitional morphology in the evolution of avian flight
- 负责人：
- DOI：
- doi:10.5061/dryad.7vb83
- 摘要：
- 's aerodynamic performance. Here, we describe the relationship between barb geometry and aerodynamic function across the evolutionary history of asymmetrical flight feather
Data from: Carrying a logger reduces escape flight speed in a passerine bird, but relative logger mass may be a misleading measure
- 负责人：
- Muijres, Florian
- DOI：
- doi:10.5061/dryad.961nn65
- 摘要：
- and aerodynamic force production in a migratory passerine. We recorded upward-directed escape flights of 15 male blackcaps. Each individual was tested without a tag
Data from: Simple parameterization of aerodynamic roughness lengths and the turbulent heat fluxes at the top of midlatitude August?one glacier
- 负责人：

- DOI：
- doi:10.5061/dryad.b2j3405
- 摘要：
- , are widely quantified by the bulk method. However, due to the difficulty of determining the aerodynamic roughness length z0m in this method, H and LE
Data from:Inferring flight parameters of Mesozoic avians through multivariate analyses of forelimb elements in their living relatives
- 负责人：
- 关键词：
- DOI：
- doi:10.5061/dryad.63k11
- 摘要：
- standing of their flight competence remains poor. Wing loading (WL) and aspect ratio (AR) are two aerodynamically relevant parameters, as they relate to energy
Data from: Evolution of short tails and breakdown of honest signaling system during a severe winter in the Pacific swallow Hirundo tahitica
- 负责人：
- DOI：
- doi:10.5061/dryad.4c963s4
- 摘要：
- In dynamic selection regimes, an honest signal that indicates high quality in favorable environments might be negatively related to quality
