Principal Investigator

I am an ecologist interested in the biogeography of land plants, mainly bryophytes. My research focuses on species distributions across space and time by characterizing species ecological niches and by taking species dispersal capacities into account.

Hi, I am Kelly and I am a PhD student. My research focuses on fine-scale ecology. I am interested in modelling the microclimate and its modulation (i.e. the buffering or amplification of the macroclimate at a local scale) in the Alps at 25-meter resolution, and in identifying climatic refugia that could be useful for species in a warming world. Another axis of my research involves studying bryophytes, which are poikilohydric organisms unable to actively regulate their water uptake and are therefore very sensitive to microclimatic changes. Projecting the microclimate and its modulation in the past and the present enables me  to evaluate the causes of the changes in bryophyte communities over these timescales.

I’m a PhD student interested in plant ecology and conservation in Europe with a particular focus on bryophytes, organisms particularly sensitive to ongoing climate changes. My research aims thus to quantify the impacts of those changes on European bryophytes using species distribution models at 100m resolution while including forest microclimate at continental scale in order to determine the extent to which these species are at risk, their ability to track the velocity of climate change and determine priority conservation areas across Europe. As I'm keen to learn more about identifying bryophytes, I'm also taking part in other projects and fieldwork that will enable me to improve my skills as a bryologist !

I am a PhD student in evolution biology & ecology, mostly interested in alpine flora dispersal capacities. My research aims to retrace the demographic history of alpine land plants (spermatophytes, pteridophytes and bryophytes) during past climatic variations through population genetic. Explicit evaluation of dispersal capacity obtained thus could deeply question the ability of species to face the velocity of ongoing global changes.
