Marine scientists have grown increasingly concerned over the loss of marine biodiversity and the need to understand the consequences of these changes has become vital. Proceedings of the National Academy of Sciences (PNAS) has published the findings of a study using seaweed species richness co-authored by Matthew Bracken, assistant professor of biology at the Marine Science Center at Northeastern University.
Titled “Complementarity in marine biodiversity manipulations: Reconciling divergent evidence from field and mesocosm experiments”, the paper contends that short-term experiments detect only a subset of possible mechanisms that operate in the field over the longer term because they lack sufficient environmental heterogeneity to allow expression of niche differences.
