Gabriel Reygondeau’s research focuses on the thematic of “The effects of climate changes and anthropogenic activities on the biogeography of the global ocean”. His current research interests can be summarized in 3 topics: (1) relations between marine organisms (from plankton to top predator), biodiversity and environmental conditions at the global scale; (2) Identification and monitoring of global marine ecosystems and (3) Evaluation of the impact of anthropogenic pressures on the global marine ecosystems.

Evaluation and Characterisation of Marine Biodiversity Under Climate Change

Gabriel Reygondeau Nereus Annual General Meeting 2016 UBC, Vancouver, Canada May 30 to June 3, 2016

Lead author Hubert du Pontavice and co-authors Didier Gascuel, Gabriel Reygondeau, Aurore Maureaud, and William Cheung recently published an article in Global Change Biology – “Climate change undermines the global functioning of marine food webs”.

Alumnus Gabriel Reygondeau is part of a research team lead by the Monterey Bay Aquarium on a new open access publication in PLoS ONE, “Towards a global understanding of the drivers of marine and terrestrial biodiversity”. In it, they created the first comprehensive global map of biodiversity distribution using both marine and terrestrial species.

Muhammed Oyinlola is lead author with Gabriel Reygondeau, Colette Wabnitz, and William Cheung as co-authors on a new study in Global Change Biology, “Projecting global mariculture diversity under climate change.” In their study, they look at how climate change will affect 85 of the most commonly farmed fish and invertebrates in coastal and open ocean areas.

Alumnus Gabriel Reygondeau (UBC/Yale University) is a main contributor to a new High Level Panel (HLP) Blue Paper on critical habitats and biodiversity. You can read the full version and summary for decision makers here.
