  1. Impact of climate change on leaf litter decomposition in french Mediterranean Region Mathieu SANTONJA Institut Méditerranéen de Biodiversité et d’Ecologie Equipe 5.1 - Diversité et Fonctionnement : des Molécules aux Ecosystèmes PhDSupervisors : Virginie BALDY and Catherine FERNANDEZ First Gozo International BioDivMex Workshop – 8.14 September 2012, Malta Mediterranean Biodiversity: Conservation and SustainableDevelopment ‏

  2. Scientist context Environmental factors Plants (Litter) Soilbiodiversity Decomposition Process Organic matter turnover and nutrient release (Lavelle and Spain 2001 ; Hattenschwiler et al. 2005 ; Berg and Laskowski 2006)

  3. Study sites « Forest » Ecosystem « Shrubland » Ecosystem Saint Michel l’Observatoire – O3HP Marseille – CLIMED Quercus pubescens Acer monspessulanum Cotinus coggygria + Pinus halepensis Quercus coccifera Cistus albidus Rosmarinus officinalis Ulex parviflorus

  4. 2 experiments of leaf litter decomposition in situ « Forest » Ecosystem « Shrubland » Ecosystem Impact of leaf litter mixtures and rainfalldecreaseon : Taxonomic and functionaldiversities of soilorganisms Loss mass, chemicalquality of leaves and nutrient release
