Building a Bird: Musculoskeletal Modeling and Simulation of Wing-Assisted Incline Running during Avian Ontogeny [PDF]
, 2018 Flapping flight is the most power-demanding mode of locomotion, associated with a suite of anatomical specializations in extant adult birds. In contrast, many developing birds use their forelimbs to negotiate environments long before acquiring “flight ...

Rotational accelerations stabilize leading edge vortices on revolving fly wings [PDF]
, 2009 The aerodynamic performance of hovering insects is largely explained by the presence of a stably attached leading edge vortex (LEV) on top of their wings. Although LEVs have been visualized on real, physically modeled, and simulated insects, the physical

Du banquet grec à l’imaginaire funéraire étrusque : les hybrides oculaires de la céramique attique
Gaia, 2022 In the iconographic corpus of female-animal hybridity in the archaic Mediterranean, one particular file catches the eye, that of the rare ocular hybridities in Attic pottery from the second half of the 6th century BC. These images, illustrating a process

Giant ants and their shape: revealing relationships in the genus Titanomyrma with geometric morphometrics [PDF]
PeerJ, 2018 Shape is a natural phenomenon inherent to many different lifeforms. A modern technique to analyse shape is geometric morphometrics (GM), which offers a whole range of methods concerning the pure shape of an object.

Ontogeny of aerial righting and wing flapping in juvenile birds [PDF]
, 2014 Mechanisms of aerial righting in juvenile Chukar Partridge (Alectoris chukar) were studied from hatching through 14 days post hatching (dph). Asymmetric movements of the wings were used from 1 to 8 dph to effect progressively more successful righting ...

The Social Organization of Honey Bees
EDIS, 2015 A honey bee colony is a superorganism, which means that together its members function like a single animal. Bees within a colony work together like the cells in a human body.

Herbivory increases diversification across insect clades. [PDF]
, 2015 Insects contain more than half of all living species, but the causes of their remarkable diversity remain poorly understood. Many authors have suggested that herbivory has accelerated diversification in many insect clades. However, others have questioned

Localized JNK signaling regulates organ size during development. [PDF]
, 2016 A fundamental question of biology is what determines organ size. Despite demonstrations that factors within organs determine their sizes, intrinsic size control mechanisms remain elusive.

Flow sensing on dragonfly wings
Annals of the New York Academy of SciencesOne feature of animal wings is their embedded mechanosensory system that can support flight control. Insect wings are particularly interesting as they are highly deformable yet the actuation is limited to the wing base.
