Abstract

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.
