Global conservation priorities
The ability to adequately protect the natural capital largely depends on the capacity to identify gaps, recognize needs, take action and evaluate the efficiency of conservation initiatives
The ability to adequately protect the natural capital largely depends on the capacity to identify gaps, recognize needs, take action and evaluate the efficiency of conservation initiatives. In a dynamic and uncertain world, the necessity to identify and account for potential drivers of change, develop flexible conservation schemes, and prioritize management efforts could contribute towards the efficient protection of global biodiversity and ecosystem services. Our active areas of research include:
- Developing of integrated biological and socioeconomic models
- Prioritizing conservation efforts
- Assessing the impacts of spatial, temporal and administrative scales upon conservation initiatives and efficiency
- Developing methodological frameworks for supporting European Union conservation policy
- Incorporating Natural security risks into conservation and management schemes

Efficiency of protected area networks
Protected areas (PAs) represent the main tool of modern society to mitigate the loss of biological diversity, thereby maintaining ecosystem functionality and services
Protected areas (PAs) represent the main tool of modern society to mitigate the loss of biological diversity, thereby maintaining ecosystem functionality and services. The new Strategic Plan for Biodiversity 2011-2020 of the Convention on Biological Diversity promotes the expansion of the global coverage of PAs, through Aichi Target 11, to reach at least 17% of land and 10% of marine waters by 2020. Undoubtedly, in human dominated regions, the establishment of PAs is challenging due to multiple human uses of land and sea, while the efficiency of the current PAs network has been largely questioned.
The goal of this research area is to contribute to the ongoing discussion on the following topics:
- How efficient is the coverage and distribution of current PAs and priority regions for expanding the global PAs network?
- How could we ensure the coherence and ecological sufficiency of protected areas?
- How efficient are networks of PAs in conserving biodiversity targets under land use and climate change? Could these networks safeguard coherence and resilience to these threats?
- How could we advance systematic conservation planning tools to satisfy alternative criteria, ensuring an optimal spatial conservation prioritisation?

Challenges for marine mega-fauna
We work at the interface between global change ecology, population dynamics and evolutionary biology.
We work at the interface between global change ecology, population dynamics and evolutionary biology. Our active areas of research include:
- Investigating the efficiency of sea turtle adaptive mechanisms to climate change
- Examining recent adaptive responses to local conditions vs distant evolutionary events on structuring the climatic niche of sea turtles
- Estimating population viability and global trends
- Prioritizing global conservation efforts and identifying risk hotspots for sea turtles

Climate change ecology
The climate of the planet is changing, affecting the distribution, abundance, dynamics, behaviour and physiology of populations and communities.
The climate of the planet is changing, affecting the distribution, abundance, dynamics, behaviour and physiology of populations and communities. Therefore, anticipating the future under the prism of climate change represents one of the main challenges that modern communities have to deal with. Recent and ongoing questions in this area include:
- Ecological responses to climate change
- Prediction of climate change impacts on species distributions and population dynamics
- Levels of climate change, climate change velocity and rate of species adaptation
