Biodiversity 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 کاملCoexistence, niches and biodiversity effects on ecosystem functioning.
General principles from coexistence theory are often invoked to explain how and why mixtures of species outperform monocultures. However, the complementarity and selection effects commonly measured in biodiversity experiments do not precisely quantify the niche and relative fitness differences that govern species coexistence. Given this lack of direct correspondence, how can we know whether spe...
متن کاملBiodiversity and Ecosystem Functioning: Experimental Systems
Experimental studies of the relationship between biodiversity and ecosystem functioning have taken two main approaches: the experimental removal of species from real communities and the construction of model communities to form gradients of diversity. The fundamental difficulty in designing biodiversity experiments is the large number of possible species combinations that make simple, unambiguo...
متن کاملBiodiversity and ecosystem functioning in dynamic landscapes.
The relationship between biodiversity and ecosystem functioning (BEF) and its consequence for ecosystem services has predominantly been studied by controlled, short-term and small-scale experiments under standardized environmental conditions and constant community compositions. However, changes in biodiversity occur in real-world ecosystems with varying environments and a dynamic community comp...
متن کاملMarine biodiversity, ecosystem functioning, and carbon cycles.
Although recent studies suggest that climate change may substantially accelerate the rate of species loss in the biosphere, only a few studies have focused on the potential consequences of a spatial reorganization of biodiversity with global warming. Here, we show a pronounced latitudinal increase in phytoplanktonic and zooplanktonic biodiversity in the extratropical North Atlantic Ocean in rec...
