  Modelling climate and land use change to identify risks of mass extinctions
  Uno Wennergren

  Mass extinctions are severe events that completely disrupt the system of biological interactions known as the food web. Given today's knowledge of the dynamics and complexity of food-webs one may ask what can cause three-fourths of species to go extinct? Two major causes and pathways will be explored: climate change and land use change. Special consideration will be taken to: (i) rate of change and generation times of species, (2) expected rates of evolution, (3) dynamical properties of food webs, (4) total biomass of a food web.
