FdV PhD Thematic workshop : From Molecules to Ecosystems
17-18 February 2011 at CRI

The aim of this workshop is to give a picture of biological studies on different scales (molecules, cells, individuals, populations and ecosystems). Uniting all these talks in a single workshop can help bring new perspectives on each field.

"From species diversity and interaction networks to ecosystem functioning and stability"
Abstract : Over the past decades, acceleratinf species extinction have prompteg rates od an increasing number of studies to assess the consequences of species diversity on ecosystem properties and the goods and services they provide to humanity. To date, well over half of diversity-functioning experiments have focused on primary producers. However, the diversity of interactions between species is a key component of biodiversity, since all organisms rely upon interactions with individuals of other species for feeding, reproducing or being protected. Knowledge of ecological interaction networks is thus essential in order to understand how species extinctions affect ecosystems.
Here, I will begin by reviewing the recent results on the links between biodiversity and ecosystem functioning in ecology, as well as their potential applications for ecosystem management. Then I will present a comparative approach between herbivory and pollination networks which shows that these two types of interaction networks differ in their structure and impacts on ecosystem stability.

Keywords: biodiversity, food webs, interaction networks, ecosystem, stability, mutualistic interactions
