GoKawiilStudy links Doñana drought and disease to new predator interactions in Spain
Researchers studying a 10-km2 plot in Doñana National Park found that severe droughts, which cut prey availability for predators by 4-5 times, coincide with unusual interactions among top predators such as lynx and raptors. The team classified drought years as those where flooding covered less than 20% of the normal maximum extent by February-March, using satellite inundation data covering 684 km2 of marshes, ponds and lagoons.
GoKawiil's interpretation of the reporting above, not reported fact.
The findings suggest that climate-driven water scarcity, compounded by disease outbreaks, may be reshaping competitive and predatory dynamics among species that would otherwise avoid direct contact, according to the researchers' framing of the study. This could offer early warning signs for conservationists managing fragile wetland ecosystems facing more frequent droughts under climate change.
- Drought years in Doñana are defined by less than 20% flooding of the marshes by February-March
- Severe droughts can cut prey availability for predators by 4 to 5 times
- Satellite data from Landsat was used to track flooding across 684 km2 of the park ecosystem
