Knowledge on the trophic niche of animal species is important for understanding their coexistence and hence diversity. Trophic niches have been shown to vary with environmental conditions, but consequences shifts food-web structure functioning little studied this applies in particular belowground communities. Here, using stable isotopes (15N, 13C), we investigated oribatid mites as model soil taxon along elevational gradients two mountain ranges Eurasia, Alps Austria Changbai Mountain China. The results showed pronounced differences use basal resources (Δ13C values) positions (Δ15N between mountains due different parent rock calcareous soils basalt bedrock Mountain. Further, changed altitude, primarily related changes litter quality. Differences were functional traits such body mass reproductive mode. Generally, isotope values closely correlated underlining importance morphological characteristics well variations niches. Moreover, differed parthenogenetic sexual species, depended rock, higher plasticity Overall, our findings highlight decisive role structuring montane food webs provide novel insight into factors responsible invertebrates.

ABSTRACT Multitrophic interactions in the soil food web represent an important factor shaping relationship between biodiversity and ecosystem functions (BEF) under changing environmental conditions. Despite some recent advancements, relative contribution, mechanisms by which multitrophic affect stability, however, remain poorly understood. Here, we provide overview of current understanding role BEF explore mechanistic pathways that may underpin their stability. We also discuss potential approaches to quantify contribution web. Specifically, highlight need for improvements empirical frameworks analytical tools quantifying strength these argue addressing key knowledge gaps understanding, research requires integration as a when predicting rate stability multifunctionality climatic

However, studying trophic interactions challenging in meta‐ecosystems, that ecosystems connected by spatial flows energy, materials and organisms across boundaries.

Highly diverse and abundant organisms coexist in soils. However, the contribution of biotic interactions between soil to microbial community assembly remains be explored. Here, we assess extent which fauna can shape using an exclusion experiment a grassland field sort biota based on body size. After 1 year, larger favoured phagotrophic protists, with increases up 32% their proportion compared no-mesh treatment. In contrast, members bacterial lesser fungal were negatively impacted. Shifts but not communities best explained by response protistan exclusion. Our findings provide empirical evidence top-down control underline importance integrating higher trophic levels for better understanding microbiome assembly.

Abstract From soil to freshwater ecosystems, decomposition can be conceived as the result of interactions between organic matter and a diversity organisms. This function is driven in part by detritivores, invertebrates that feed on detritus or graze its associated microbes have significant but extremely variable contribution decomposition. In order better understand predict detritivore–detritus pairwise interactions, we propose conceptual framework, called Detri 2 match, study consumption detri tus tivores, using trait‐ match ing approach at individual detritivore level. Here, focus interaction saprophagous detritivores fragment plant detritus. We novel definition an animal consumes when traits sufficiently resource, passing through five facets consumption. These include (1) spatial rule regarding encounter, (2) biomechanical ingestion, (3) digestive assimilation, (4) energetic fulfilment metabolic needs (5) nutritional chemical element adapted proportions. The main goal this framework guide future research establish generic rules misunderstood detritus–detritivore identifying relevant their key for both investigation should conducted over temporal variability trait‐matching constraints throughout whole process. Coupled with adequate accumulation trait information, could also facilitate predictions inference non‐tested detritivore–litter interactions. outline conceptual, methodological analytical challenges framework. challenge would scale up these detrital network level test genericity, which contribute understanding functioning Read free Plain Language Summary article Journal blog.
