Wing bone geometry reveals active flight in Archaeopteryx

Autor: Dennis F. A. E. Voeten, Jorge Cubo, Emmanuel de Margerie, Martin Röper, Vincent Beyrand, Stanislav Bureš, Paul Tafforeau, Sophie Sanchez

Publikováno v: Nature Communications, Vol 9, Iss 1, Pp 1-9 (2018)

Archaeopteryx had a mix of traits seen in non-flying dinosaurs and flying birds, leading to debate on whether it had powered flight. Here, Voeten et al. compare wing bone architecture from Archaeopteryx and both flying and non-flying archosaurs, supp

Towards a postural indicator of back pain in horses (Equus caballus).

Autor: Clémence Lesimple, Carole Fureix, Emmanuel De Margerie, Emilie Sénèque, Hervé Menguy, Martine Hausberger

Publikováno v: PLoS ONE, Vol 7, Iss 9, p e44604 (2012)

Postures have long been used and proved useful to describe animals' behaviours and emotional states, but remains difficult to assess objectively in field conditions. A recent study performed on horses using geometric morphometrics revealed important

Development of fearfulness in birds: genetic factors modulate non-genetic maternal influences.

Autor: Cécilia Houdelier, Sophie Lumineau, Aline Bertin, Floriane Guibert, Emmanuel De Margerie, Matthieu Augery, Marie-Annick Richard-Yris

Publikováno v: PLoS ONE, Vol 6, Iss 1, p e14604 (2011)

The development of fearfulness and the capacity of animals to cope with stressful events are particularly sensitive to early experience with mothers in a wide range of species. However, intrinsic characteristics of young animals can modulate maternal

Drink safely: common swifts (Apus apus) dissipate mechanical energy to decrease flight speed before touch-and-go drinking

Journal of Experimental Biology, 2023, ⟨10.1242/jeb.244961⟩

Flight is an efficient way of transport over a unit of distance, but it can be very costly over each unit of time, and reducing flight energy expenditure is a major selective pressure in birds. The common swift (Apus apus) is one of the most aerial b

Flight behaviours and energy savings in adult and juvenile house martins (Delichon urbicum) foraging near their breeding colony

International audience; Foraging is an extremely important behaviour for birds, especially during the breeding season, when they have to carry the cost of incubation and chick rearing, in addition to their own energy needs. Aerial insectivores perfor

International audience; Flight is a unique adaptation at the core of many behaviours in most bird species, whether it be foraging, migration or breeding. Birds have developed a wide diversity of flight modes (e.g. flapping, gliding, soaring, hovering

International audience; Beyond the genetic links between mother and young, prenatal effects experienced by offspring can modulate their mother’s behaviour and stress. Here we investigated the consequences of stress-induced prenatal maternal effects

Gliding for a free lunch: biomechanics of foraging flight in common swifts (

Autor: Tyson L, Hedrick, Cécile, Pichot, Emmanuel, de Margerie

Publikováno v: The Journal of experimental biology. 221(Pt 22)

Although the biomechanics of animal flight have been well studied in laboratory apparatus such as wind tunnels for many years, the applicability of these data to natural flight behaviour has been examined in few instances and mostly in the context of

International audience; How predators search for prey is a cornerstone question in behavioural ecology, which has yet to be investigated for animals foraging in 3D airspace. Do insectivorous birds such as swifts (Apodidae), swallows and martins (Hiru
