Impact of belowground biomass responses on the biodiversity-ecosystem functioning relationship

In this new video podcast, Marc-Olivier Martin-Guay highlights the role of belowground responses in biodiversity-ecosystem functioning relationship, asking three main questions: does adding below-ground biomass change diversity effect estimations? Do species shift their biomass allocation strategies within mixtures? Do we interpret correctly the origins of these diversity effects when ignoring below-ground biomass? Have a look at the video to discover what he found!

Marc-Olivier’s findings have recently been published in Journal of Ecology so if you want to know more, check out the full paper entitled “Implications of contrasted above‐ and below‐ground biomass responses in a diversity experiment with trees“. 

Marc-Olivier’s video can also be found on the Journal of Ecology YouTube channel (English subtitles available).


Marc-Olivier Martin-Guay is a plant ecologist who worked mainly on the link between biodiversity and ecosystem functioning. He first worked on a tree diversity experiment from the International Diversity Experiment Network with Trees (IDENT) as part of his master’s degree, but he also worked on a meta-analysis characterizing the effects of crop species diversity. He is currently a research professional at Université du Québec à Montréal.
