Dragonflies use vision, subtle wing control to straighten up and fly right（图）
蜻蜓 视觉 翅膀 伸直 向右飞翔
2023/5/22
With their stretched bodies, immense wingspan and iridescent coloring, dragonflies are a unique sight. But their originality doesn’t end with their looks: As one of the oldest insect species on the pl...
If you brush against the wings of a butterfly, you will likely come away with a fine sprinkling of powder. This lepidopteran dust is made up of tiny microscopic scales, hundreds of thousands of which ...
Factors Affecting the Incidence of Angel Wing in White Roman Geese: Stocking Density and Genetic Selection
Angel Wing Stocking Density Genetics White Roman Geese
2016/7/27
The present study investigated stocking density and genetic lines, factors that may alter the severity and incidence of angel wing (AW), in White Roman geese. Geese (n = 384) from two genetically sele...

Tiny muscles help bats fine-tune flight, stiffen wing skin
Tiny muscles bats fine-tune flight stiffen wing skin
2014/6/19
Bats appear to use a network of hair-thin muscles in their wing skin to control the stiffness and shape of their wings as they fly, according to a new study. The finding provides new insight about the...

2014/3/20
A single gene regulates the complex wing patterns, colors and structures required for mimicry in swallowtail butterflies, report scientists from the University of Chicago, March 5 in Nature. Surp...
From wing to wing: the persistence of long ecological interaction chains in less-disturbed ecosystems
wing ecological interaction chains
2015/11/13
Human impact on biodiversity usually is measured by reduction in species abundance or richness. Just as
important, but much more difficult to discern, is the anthropogenic elimination of ecological i...

The asymmetry of the carpal joint and the evolution of wing folding in maniraptoran theropod dinosaurs
Laboratory of Evolutionary Systematics of Vertebrates Institute of Vertebrate Palaeontology
2014/3/26
In extant birds, the hand is permanently abducted towards the ulna, and the wrist joint can bend exten-
sively in this direction to fold the wing when not in use. Anatomically, this asymmetric mobili...
A 3-D four-wing attractor and its analysis
Chaos four-wing attractor Lyapunov exponents bifurcation
2010/7/8
In this paper, several three dimensional (3-D) four-wing smooth quadratic autonomous chaotic systems are analyzed. It is shown that these systems have a number of similar features. A new 3-D continuou...
