Dr Belgrano is broadly interested in ecological and evolutionary studies that use ecosystem status and trend data, for characterising relationships between diversity patterns and ecosystem functioning, which includes the effect of commercial fisheries, climate change and environmental variability.
His research approach is to use the broad concepts of macroecology, food webs theory and evolution to understand the underlying common rules governing ecosystem dynamics and functioning. Most of Dr Belgrano's current work focuses on functional biodiversity, ecosystem-based management for marine fisheries, ocean health, governance, sustainability and resilience in aquatic systems.
The general theme is being based around the ongoing European Science Foundation SIZEMIC Research Network, which has been running for several years. The network has focused on the role of body size in ecosystems and embraces a wide remit that spans all ecosystem types and a range of disciplines, from theoretical to applied ecology.
