Biodiversity losses are increasing as a consequence of negative anthropogenic effects on ecosystem
dynamics. However, the magnitude and complexity of these effects may still be greatly underestimated.
Most Old World vultures have experienced rapid population declines in recent years. In Europe, their
immediate conservation depends on changes in health regulations affecting the availability of food provided
by domestic carcasses. Information is lacking on the effects of a hypothetical food shortage on the
population dynamics of vultures, and is necessary to assess the potential impacts of policy decisions on
future changes in biodiversity and ecosystem services.Anovel computational model (P-systems) was used to
model these effects, forecasting a rapid decline in the Eurasian griffon vulture (Gyps fulvus). By contrast,
vulture species with greater plasticity in their dietary range appeared less sensitive to declining food
availability. This study extends our understanding of vulture ecosystem services, which have social and
economic implications. |
