Food-web constraints on biodiversity-ecosystem functioning relationships.
The consequences of biodiversity loss for ecosystem functioning and ecosystem services have aroused considerable interest during the past decade. Recent work has focused mainly on the impact of species diversity within single trophic levels, both experimentally and theoretically. Experiments have usually showed increased plant biomass and productivity with increasing plant diversity. Changes in...
متن کاملTowards a food web perspective on biodiversity and ecosystem functioning
One of the most common questions asked by researchers across a variety of scientific disciplines is ‘How does the number of nodes connected together into a network influence the efficiency and reliability of that network?’. While social scientists and epidemiologists might think of ‘nodes’ and ‘connections’ as people interacting within a social network, computer scientists, neurologists, and ci...
متن کاملBiodiversity and Ecosystem Functioning
Species diversity is a major determinant of ecosystem productivity, stability, invasibility, and nutrient dynamics. Hundreds of studies spanning terrestrial, aquatic, and marine ecosystems show that high-diversity mixtures are approximately twice as productive as monocultures of the same species and that this difference increases through time. These impacts of higher diversity have multiple cau...
متن کاملBiodiversity and ecosystem functioning in evolving food webs.
We use computer simulations in order to study the interplay between biodiversity and ecosystem functioning (BEF) during both the formation and the ongoing evolution of large food webs. A species in our model is characterized by its own body mass, its preferred prey body mass and the width of its potential prey body mass spectrum. On an ecological time scale, population dynamics determines which...
متن کاملPhylogenetic constraints on ecosystem functioning.
There is consensus that biodiversity losses will result in declining ecosystem functioning if species have different functional traits. Phylogenetic diversity has recently been suggested as a predictor of ecosystem functioning because it could approximate the functional complementarity among species. Here we describe an experiment that takes advantage of the rapid evolutionary response of bacte...
