Functional and Taxonomic Structuring of Ground-Dwelling Spider Communities Under the Combined Effects of the Environment and Metal Contamination.
Article in Ecology and evolution, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Northern regions of France have historically experienced mining and steel production activities, leading to the emergence of multi-contaminated soils by metals. These metals are a source of indirect disruption to ecosystem functioning through the alteration of biodiversity. We focused on spiders, which are major regulators of terrestrial ecosystems, acting simultaneously as prey, predators and competitors in soil communities. The aim of this study was to assess the impact of metal contamination, among a set of environmental parameters, on the taxonomic and functional structures of spider communities; to identify indicator spider species; and to define trait syndromes specific to metal-contaminated wastelands. We sampled spiders in 40 sites that represented a metal-contamination gradient. We have shown that certain environmental parameters largely account for the taxonomic and functional structure of spider assemblages (e.g., soil granulometry, vegetation, pH). The concentrations of metals in the soil (Ag, Al, As, Cd, Mn, Pb, Sb and Zn) also had a significant but less pronounced impact. We have identified
