Our group is within CIBIO/ BIOPOLIS/ University of Porto. We carry out ecological studies of endangered steppe birds in Iberia, which is a hotspot for steppe bird diversity but vulnerable to environmental and climate change. Most of our research combines GPS tracking data from tagged birds with high-resolution environmental and climatic data from remote sensing, to provide an in-depth understanding into a wide range of ecological processes. Overall, we aim to give insight into the functioning of these unique and important ecosystems.
Our specific aims are to:

Our team was present at ICPSB 2025! João Paulo Silva gave a plenary on steppe birds & power lines, while our ECR shared their work on the ecology, tagging & conservation of steppe birds! A week full of inspiring discussions and new collaborations! #SteppeBirds2025
New Paper Alert! 🚨 Our latest research on the #LittleBustard is out! Using high-resolution Individual-Based Models (IBMs), we show that habitat improvements aren’t enough—urgent action is needed to reduce adult mortality in Extremadura!

Big week for our team at #26CEO! We presented 3 posters with fresh insights on: #GPS loggers & their impact on tagged birds, #sandgrouse breeding performance and the decline of #Montagusharrier in Portugal. Exciting discussions and great feedback!
