The relationship between biodiversity and ecosystem functions (BEFs) has attracted great interest. Studies on BEF have so far focused the average trend of function as species diversity increases. A tantalizing but rarely addressed question is why large variations in are often observed across systems with similar diversity, likely obscuring BEFs. Here we use a multi-trophic food web model combination empirical data to examine relationships richness variation (VEFs) including biomass, metabolism, decomposition, primary secondary production. We then probe mechanisms underlying these relationships, focusing role trophic interactions. While our results reinforce previously documented positive found that exhibit significant within each level magnitude this displays hump-shaped richness. Our analyses demonstrate VEFs reduced when consumer increases through elevated nonlinearity interactions, and/or basal such producers decomposers decreases. This explanation supported by 34-year time series from Gulf Riga ecosystem. work suggests loss may not only result decline, also reduce predictability generating greater variability among ecosystems. It thus helps reconcile debate generality disentangle drivers stability. interactions their strengths mediated functional responses shaping warrants further investigations better incorporation into 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.

Human-induced biodiversity change impairs ecosystem functions crucial to human well-being. However, the consequences of this for multifunctionality are poorly understood beyond effects plant species loss, particularly in regions with high across trophic levels. Here we adopt a multitrophic perspective analyze how affects biodiverse subtropical forests. We consider 22 independent measurements nine central energy and nutrient flow find that individual more strongly affected by diversity heterotrophs promoting decomposition cycling, functional-trait composition, than tree richness. Moreover, cascading higher trophic-level on originating from lower processes highlight is key understanding drivers multifunctionality. A broader biodiversity-multifunctionality relationships sustainable management light non-random loss intensified biotic disturbances under future environmental change.

Abstract Human‐induced global change dramatically alters individual aspects of river biodiversity, such as taxonomic, phylogenetic or functional diversity, and is predicted to lead losses associated ecosystem functions. Understanding these dependencies are critical human well‐being. Until now, however, most studies have only looked either at organismal groups single functions, little known on the effect activities multitrophic biodiversity multifunctionality in riverine ecosystem. Here we profiled from bacteria invertebrates based environmental DNA (hereafter, ‘eDNA’) samples across a major catchment China, analysed their with multiple especially linked C/N/P‐cycling. Firstly, found spatial cross‐taxon congruence pattern communities' structure network Shaying river, which was related strong filtering due land use. Secondly, use explained decline multifaceted but increased redundancy Thirdly, function relationships an integrative level showed concave‐up (non‐saturating) shape. Finally, structural equation modeling suggested that affects functions through biodiversity‐mediated pathways, including loss altered community interdependence groups.

Understanding how biodiversity (B) affects ecosystem functioning (EF) is essential for assessing the consequences of ongoing changes. An increasing number studies, however, show that environmental conditions affect shape BEF relationships. Here, we first use a game-theoretic community model to reveal unimodal response slope can be expected along stress gradients, but also ecological mechanisms underlying this may vary depending on species interactions. Next, analysed global dataset 44 experiments crossed with conditions.

Most ecosystem functions and related services involve species interactions across trophic levels, for example, pollination biological pest control. Despite this, our understanding of function in multitrophic communities is poor, research has been limited to either manipulation small or statistical descriptions larger ones. Recent advances food web ecology may allow us overcome the trade-off between mechanistic insight ecological realism. Molecular tools now simplify detection feeding interactions, trait-based approaches application dynamic models real ecosystems.

Ecosystems respond in various ways to disturbances. Quantifying ecological stability therefore requires inspecting multiple properties, such as resistance, recovery, persistence and invariability. Correlations among these properties can reduce the dimensionality of stability, simplifying study environmental effects on ecosystems. A key question is how kind disturbance affects correlations. We here investigated effect three types (random, species-specific, local) applied at four intensity levels, population community level. used previously parameterized models that represent five natural communities, varying species richness number trophic levels. found type but not affected only The also varied greatly communities. Therefore, studying cannot be simplified using a single metric multi-dimensional assessments are still recommended.
