Ricardo Scrosati

Ricardo Scrosati is a Professor in the Department of Biology at St. Francis Xavier University (StFX), where he leads the Marine Ecology Lab. He holds a Ph.D. from the University of British Columbia (1997) and a Licenciate from the University of Buenos Aires (1987). Previously, he held positions at the Northwest Biological Research Centre (Mexico), Bamfield Marine Sciences Centre (Canada), University of British Columbia, University of Concepción (Chile), and University of Buenos Aires. From 2004–2014, he was a Canada Research Chair.

His research specializes in coastal marine ecology, focusing on:

• Rocky intertidal community dynamics under climate change
• Nonconsumptive predator-prey interactions
• Foundation species (mussels, seaweeds) as ecosystem engineers
• Latitudinal biodiversity patterns
• Benthic-pelagic coupling
• Recovery from extreme climate events

Analysis of his 15 most recent articles (2024–2025) reveals dominant themes:

• Climate-driven shifts in recruitment/recovery of barnacles/mussels
• Impacts of marine heatwaves and cold snaps on intertidal ecosystems
• Global patterns in invertebrate metacommunities
• Biochemical and behavioral adaptations to environmental stress

Awards:

• Canada Research Chair (2004–2014)

He mentors students through his Marine Ecology Lab and conducts field research along Canada's Atlantic coast, utilizing long-term monitoring to track ecological change.
