Impact of a 3-day Dry immersion on posture and craniamandibular spinal axis.

Picture of model of Dry immersion: (CNES Source)

We will study the morphological and analytic modifications on rachis, the functional and postural consequences linked to an exposure to microgravity. The vertebral deconditioning described after spaceflight would be simulated accuracy and rapidly with the experiment of a 3-Day dry immersion. We would like to show the link between the spinal modifications objectified by Magnetic Resonance Imaging and Spectroscopy (MRI/MRS), the osteopathic vertebral tests and the postural changes at recovery in load. The goal is to compare the results about back pain in the two model of microgravity simulated which are head-down bed rest and dry immersion. Finally we would like to formulate a basis to understand ant to prevent back pains and intervertebral discs herniations at return on earth.

Road bound landscapes as habitat: a main asset for rodents in an intensive farming landscape

When a road is built, new landscapes appear such as road verges, excavation slopes or storm water basins. Furthermore, in a biological desert like intensive farming landscape, environmental negative effects of the linear can’t be applied on non-present species anyways. We thus hypothesize that road bound landscapes can be beneficial for the environment as sustainable habitats. During the first year, we investigated the quality of road bound landscapes and the density of rodents, as preys, which are living there.

A comparative study of the flexibility of vocal communication in four species of macaque

The ‘social complexity hypothesis’ predicts that complex social systems require complex communications to regulate social interactions. In macaques, some species appear intolerant and hierarchical, whereas others are more tolerant and egalitarian. By comparing their vocal communications, I will test the existence of a link between social style and vocal flexibility.
