Scaling‐up biodiversity‐ecosystem functioning research

Abstract A rich body of knowledge links biodiversity to ecosystem functioning (BEF), but it is primarily focused on small scales. We review the current theory and identify six expectations for scale dependence in BEF relationship: (1) a nonlinear change slope relationship with spatial scale; (2) scale‐dependent between stability extent; (3) coexistence within among sites will result positive at larger scales; (4) temporal autocorrelation environmental variability affects species turnover thus (5) connectivity metacommunities generates relationships by affecting population synchrony local regional (6) scaling food web structure diversity generate functioning. suggest directions synthesis that combine approaches metaecosystem metacommunity ecology integrate cross‐scale feedbacks. Tests this may remote sensing generation networked experiments assess effects multiple also show how anthropogenic land cover alter relationship. New research role guide policy linking goals managing ecosystems.

Ecological and socio-economic functions across tropical land use systems after rainforest conversion

Philosophical Transactions of the Royal Society B Biological Sciences, Journal Year: 2016, Volume and Issue: 371(1694), P. 20150275 - 20150275

Tropical lowland rainforests are increasingly threatened by the expansion of agriculture and extraction natural resources. In Jambi Province, Indonesia, interdisciplinary EFForTS project focuses on ecological socio-economic dimensions rainforest conversion to jungle rubber agroforests monoculture plantations oil palm. Our data confirm that transformation land use intensification lead substantial losses in biodiversity related ecosystem functions, such as decreased above- below-ground carbon stocks. Owing rapid step-wise from forests renewal each plantation type every few decades, converted systems continuously dynamic, thus hampering adaptation animal plant communities. On other hand, agricultural provide increased income access education, especially for migrant smallholders. Jungle monocultures associated with higher financial productivity but lower labour compared palm, which influences crop choice: smallholders labour-scarce would prefer palm while land-scarce rubber. Collecting long-term an context enables us decision-makers stakeholders scientific insights facilitate reconciliation between economic interests sustainability tropical landscapes.

Plant diversity effects on grassland productivity are robust to both nutrient enrichment and drought

Philosophical Transactions of the Royal Society B Biological Sciences, Journal Year: 2016, Volume and Issue: 371(1694), P. 20150277 - 20150277

Published: April 26, 2016

Global change drivers are rapidly altering resource availability and biodiversity. While there is consensus that greater biodiversity increases the functioning of ecosystems, extent to which buffers ecosystem productivity in response changes remains unclear. We use data from 16 grassland experiments across North America Europe manipulated plant species richness one two essential resources-soil nutrients or water-to assess direction strength interaction between diversity alteration on above-ground net biodiversity, complementarity, selection effects. Despite strong with nutrient addition decreases drought, we found alterations did not alter biodiversity-ecosystem relationships. Our results suggest these relationships largely determined by complementarity effects along gradients. Although reduced at high diversity, this appears be due biomass monocultures under enrichment. indicate important regulators productivity, regardless other function.

Clarifying the effect of biodiversity on productivity in natural ecosystems with longitudinal data and methods for causal inference

Nature Communications, Journal Year: 2023, Volume and Issue: 14(1)

Published: May 5, 2023

Abstract Causal effects of biodiversity on ecosystem functions can be estimated using experimental or observational designs — that pose a tradeoff between drawing credible causal inferences from correlations and generalizable inferences. Here, we develop design reduces this revisits the question how plant species diversity affects productivity. Our leverages longitudinal data 43 grasslands in 11 countries approaches borrowed fields outside ecology to draw data. Contrary many prior studies, estimate increases plot-level richness caused productivity decline: 10% increase decreased by 2.4%, 95% CI [−4.1, −0.74]. This contradiction stems two sources. First, studies incompletely control for confounding factors. Second, most experiments fewer rare non-native than exist nature. Although native, dominant increased productivity, making average effect negative our study. By reducing designs, study demonstrates complement ecological inform future ones.

Locally rare species influence grassland ecosystem multifunctionality

Philosophical Transactions of the Royal Society B Biological Sciences, Journal Year: 2016, Volume and Issue: 371(1694), P. 20150269 - 20150269

Published: April 26, 2016

Species diversity promotes the delivery of multiple ecosystem functions (multifunctionality). However, relative functional importance rare and common species in driving biodiversity–multifunctionality relationship remains unknown. We studied between (according to their local abundances across nine different trophic groups), multifunctionality indices derived from 14 on 150 grasslands a land-use intensity (LUI) gradient. The above- below-ground had opposite effects, with above-ground being associated high levels multifunctionality, probably because effects did not trade off against each other. Conversely, were only related average, high, declined LUI. Apart community-level diversity, we found significant positive associations abundance individual 6% tested. Species-specific best predicted by response LUI: that land use intensification those higher multifunctionality. Our results highlight for help guiding future conservation priorities.

Biodiversity and ecosystem functioning in food webs: the vertical diversity hypothesis

Ecology Letters, Journal Year: 2017, Volume and Issue: 21(1), P. 9 - 20

Published: Oct. 22, 2017

One challenge in merging community and ecosystem ecology is to integrate the complexity of natural multitrophic communities into concepts functioning. Here, we combine food-web allometry theories demonstrate that primary production, as measured by total nutrient uptake community, determined vertical diversity (i.e. food web's maximum trophic level) structure distributions species their abundances metabolic rates across levels). In ecosystems, size distribution determines all these patterns thus uptake. Our model suggests a hypothesis (VDH) for functioning complex webs. It predicts that, under given supply, increases exponentially with level web it its body according power law. The VDH highlights effect top-down regulation on plant uptake, which complements traditional paradigms emphasised bottom-up supply diversity. We conclude contributes synthetic framework understanding relationship between webs predicting impacts global changes ecosystems.
