Abstract

Despite the poblems they cause, biological invasions can be seen as a great opportunity to study large scale plant evolution, e.g. in response to climate. Our study model, Senecio inaequidens DC., is a herbaceous perrenial originating from South Africa. It was introduced as a wool alien in a few precise locations about one century ago and after a lag phase of several decades, started to spread rapidly throughout Europe and its contrasted climate. Our study uses common garden experiments to assess the differenvciation of the species between continents and within the introduction range. Then, life history traits are measured and linked to evironemental conditions of source populations. Seing preliminary results, the species seem to have evolved in response to climate. Reciprocal transplants will help interpreting adaptative benefit of the observed evolutions. Finally, understanding the adaptative response of a plant to new climatic conditions will help anticipating the potential response of the flora (even the native one) to climate change.
