Hypothesis
Is the biomass from wild ungulates sufficient to meet the energy needs of avian scavengers?
Conclusion
Wild ungulates can support vulture populations in the Pyrenees, but in the Pre-Pyrenees, they are insufficient without domestic ungulate carcasses.
Supporting Evidence
- Wild ungulates provide significant food resources for vultures in the Pyrenees.
- In the Pre-Pyrenees, food from wild ungulates alone is insufficient for vulture population growth.
- Public health policies limiting domestic ungulate carcasses can negatively impact vulture populations.
- Supplementary feeding may be necessary in areas where wild ungulate biomass is low.
Takeaway
This study looks at whether dead wild animals can provide enough food for vultures. It finds that in some areas, they can, but in others, they can't without extra help.
Methodology
The study used a P System computational model to assess food resources from wild ungulates and their impact on vulture population dynamics.
Potential Biases
Potential bias from reliance on model simulations rather than direct field observations.
Limitations
The study is limited to specific regions in NE Spain and may not be generalizable to all areas with vultures.
Participant Demographics
The study focused on three vulture species in NE Spain: bearded vulture, Egyptian vulture, and griffon vulture.
