Plant diversity and ecosystem productivity: theoretical considerations.
Ecosystem processes are thought to depend on both the number and identity of the species present in an ecosystem, but mathematical theory predicting this has been lacking. Here we present three simple models of interspecific competitive interactions in communities containing various numbers of randomly chosen species. All three models predict that, on average, productivity increases asymptotica...
متن کاملIncorporating plant functional diversity effects in ecosystem service assessments.
Global environmental change affects the sustained provision of a wide set of ecosystem services. Although the delivery of ecosystem services is strongly affected by abiotic drivers and direct land use effects, it is also modulated by the functional diversity of biological communities (the value, range, and relative abundance of functional traits in a given ecosystem). The focus of this article ...
متن کاملFunctional identity and diversity of animals predict ecosystem functioning better than species-based indices.
Drastic biodiversity declines have raised concerns about the deterioration of ecosystem functions and have motivated much recent research on the relationship between species diversity and ecosystem functioning. A functional trait framework has been proposed to improve the mechanistic understanding of this relationship, but this has rarely been tested for organisms other than plants. We analysed...
متن کاملPositive Effects of Bacterial Diversity on Ecosystem Functioning Driven by Complementarity Effects in a Bioremediation Context
Despite their importance as ecosystem drivers, our understanding of the influence of bacterial diversity on ecosystem functioning is limited. After identifying twelve bacterial strains from two petroleum-contaminated sites, we experimentally explored the impact of biodiversity on total density by manipulating the number of strains in culture. Irrespective of the origin of the bacteria relative ...
متن کاملEcosystem Functioning and Plant-Soil Interactions in Forests Influences of quality and diversity of resources
The aim of this thesis was to investigate the role of resources in driving ecosystem processes and in influencing soil-and plant communities in boreal and temperate forests, through four complementary experimental studies. In the first study, plant and soil microbial responses to the quality and diversity of added organic substrates from boreal forests were investigated. The substrate-diversity...
