Variation in the methods leads to variation in the interpretation of biodiversity–ecosystem multifunctionality relationships

Biodiversity is often positively related to the capacity of an ecosystem to provide multiple functions simultaneously (i.e. multifunctionality). However, there is some controversy over whether

Human perturbations reduce dung beetle diversity and dung removal ecosystem function

Biodiversity drives ecological functioning, ultimately providing ecosystem services. Ecosystem processes are favored by greater functional diversity, particularly when groups of functionally

Promoting Biodiversity Conservation Requires a Better Understanding of the Relationships Between Ecosystem Services and Multiple Biodiversity Dimensions

In order to reverse the global trend of biodiversity loss, the concept of ecosystem services has been widely applied to make policymakers and the general public realize that conserving biodiversity

A Research Agenda for Microclimate Ecology in Human-Modified Tropical Forests

Logging and habitat fragmentation impact tropical forest ecosystems in numerous ways, perhaps the most striking of which is by altering the temperature, humidity, and light environment of the

Multispecies for multifunctions: combining four complementary species enhances multifunctionality of sown grassland

Sown grass–legume mixtures combining few complementary species at low to moderate N fertilisation sustain high multifunctionality and are a ‘ready-to-use’ option for the sustainable intensification of agriculture.

The impact of global climate change on the number and replacement of provisioning ecosystem services of Brazilian Cerrado plants

This work aims to map the richness of provisioning ecosystem services from economically important native plants, and use forecasts of the distribution of ecosystem services to assess areas of changes in the number and type of Provisioning ecosystems services.



Higher levels of multiple ecosystem services are found in forests with more tree species

It is reported that tree species richness in production forests shows positive to positively hump-shaped relationships with multiple ecosystem services, including production of tree biomass, soil carbon storage, berry production and game production potential.

Testing the effects of diversity on ecosystem multifunctionality using a multivariate model

A multivariate modelling framework for quantifying the relationship between biodiversity and multiple ecosystem functions (multifunctionality) is proposed and found high variability in performance across the functions in monocultures, but as community diversity increased, performance increased and variability across functions decreased.

The importance of species identity and interactions for multifunctionality depends on how ecosystem functions are valued.

Using the multivariate diversity-interactions framework, a desirability function approach was developed to examine how individual species and species mixtures contribute to a desired state of overall ecosystem functioning, revealing how multiple aspects of biodiversity can simultaneously drive ecosystem functioning.

Sustaining multiple ecosystem functions in grassland communities requires higher biodiversity

This work uses data from the longest-running biodiversity-functioning field experiment to date to test how species diversity affects the ability of grassland ecosystems to provide threshold levels of up to eight ecosystem functions simultaneously.

Biodiversity and ecosystem function: making sense of numerous species interactions in multi-species communities.

This work extends Diversity-Interactions models to describe the effects of diversity on ecosystem function using a combination of fixed coefficients and random effects, which considerably reduces the complexities associated with understanding how species interactions contribute to ecosystem function in species-rich ecosystems.

Diversity-interaction modeling: estimating contributions of species identities and interactions to ecosystem function.

A modeling framework that estimates the effects of species identity and diversity on ecosystem function and permits prediction of the diversity-function relationship across different types of community composition and describes community-level performance, which can be tailored to test many hypotheses in biodiversity research.

Biodiversity and ecosystem multifunctionality

It is shown that ecosystem multifunctionality does require greater numbers of species, and studies focusing on individual processes in isolation will underestimate levels of biodiversity required to maintain multifunctional ecosystems.

Effects of biodiversity on the functioning of trophic groups and ecosystems

A formal meta-analysis of studies that have experimentally manipulated species diversity to examine how it affects the functioning of numerous trophic groups in multiple types of ecosystem suggests that the average effect of decreasing species richness is to decrease the abundance or biomass of the focal Trophic group, leading to less complete depletion of resources used by that group.

Revisiting the biodiversity–ecosystem multifunctionality relationship

It is shown here that the relationship between biodiversity and ecosystem functioning does not change with the number of functions considered, and the effect on multifunctionality equals the average effect on single functions.
