Abstract

Biodiversity in the ecosystem The positive relationship between biodiversity and ecosystem function is well established, but the specific shape of the relationship can vary. A study combining experimental evolution with a biodiversity–ecosystem functioning experiment helps to fill in the details. Twenty marine bacterial species were evolved so that they were adapted to few (specialists) or many (generalists) resources, and the biodiversity of communities constructed from these derived strains was manipulated. Assemblages of specialists proved more productive on average as they could exploit environmental heterogeneity, but specialists contribute more to the slope of the biodiversity–ecosystem function curve. This work provides the first experimental evidence that evolutionary history shapes the functional consequences of species extinctions, and is relevant to work on conservation strategies.
