Southern elephant seals (Mirounga leonina) are known to move about and aggregate while moulting. A total of 23 adult females were equipped with GPS tags during 4 moulting seasons, from 2012 to 2016. Results suggest a selection of habitat by moulting elephant seals linked with their thermal constraints. Females moved 590 ± 237 m per day and their movements. Our results showed that elephant seals were sensible to environmental variations on land and suggested that they adapted their behaviour in order to save energy while moulting.

My PhD aims at understanding how people’s mobility and socio-environmental variables conjointly impact their health. To do so, a cohort’s accelerometer data, GIS and social network are analyzed against various health outcomes.

We used Geographic Information Systems and computer-assisted questionnaires to evaluate older adults’ social network and activity space, and to question how network members are related to activity locations. Preliminary results indicate, firstly, that the spatial distribution of activity locations seems more spaced and clustered in rural area compared to urban and suburban areas. Secondly, the degree distributions of bipartite socio-spatial networks illustrate that certain places are connected to a high proportion of people, while certain people are connected to a high proportion of activity locations.
