Molecular Phylogenetics and the Diversification of Hummingbirds
The tempo of species diversification in large clades can reveal fundamental evolutionary mechanisms that operate on large temporal and spatial scales. Hummingbirds have radiated into a diverseExpand

Mechanics of Forward Flight in Bumblebees: II. QUASI-STEADY LIFT AND POWER REQUIREMENTS
This paper examines the aerodynamics and power requirements of forward flight in bumblebees. Measurements weremade of the steady-state lift and drag forces acting on bumblebee wings and bodies. TheExpand

Implications of the late Palaeozoic oxygen pulse for physiology and evolution
The late Palaeozoic was marked by significant changes in atmospheric chemistry and biotic composition. Geochemical models suggest a marked increase and then decline of atmospheric oxygen andExpand

An integrative approach to understanding bird origins
Background The origin of birds is one of the most enduring and dramatic evolutionary debates. The hypothesis that the primarily small-sized birds are nested within a theropod dinosaur group thatExpand

Mechanics of Forward Flight in Bumblebees: I. Kinematics and Morphology
Using high-speed cinematography, bumblebees in free flight were filmed over a range of forward airspeeds. A detailed description of the wing tip and body kinematics was obtained from aExpand

On the biogeography of salt limitation: A study of ant communities
Sodium is an essential nutrient whose deposition in rainfall decreases with distance inland. The herbivores and microbial decomposers that feed on sodium-poor vegetation should be particularlyExpand

Limits to vertebrate locomotor energetics suggested by hummingbirds hovering in heliox
OXYGEN consumption1 and muscle power output2 of hovering hummingbirds are among the highest recorded for vertebrates. Maximum performance of hummingbirds thus approaches the upper limits ofExpand
