1 · What the graph read from it

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.

2 · The registry

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

Forest ecosystems are shaped by the consequences of management activities, as well as through an increase in tree damage and mortality caused by climate change. These drivers lead to alterations in forest structure, affecting the abundance, diversity, and composition of organisms, as well as their provision of ecosystem functions. However, relatively little is known about how dung beetles, which are important for ecosystem functioning, respond to recent changes in forest characteristics. We monitored dung beetles and dung decomposition in 67 forest plots in Darmstadt, Germany. The structure of these plots varied considerably due to tree mortality caused by several years of drought and heatwaves, as well as former forest management practices in the study region. The total biomass, diversity, and species composition of dung beetles strongly corresponded to changes in forest structure, such as mean canopy openness, mean tree diameter at breast height, and forest ground cover. However, they were less related to within-plot environmental heterogeneity. Higher dung beetle biomass was related to a higher dung decomposition rate, but changes in dung beetle diversity and community composition did not correlate with dung decomposition. Our results suggest that changes in forest structure result in changes in the biomass, diversity, and composition of dung beetle communities. The relationships between dung beetles and structural heterogeneity were not particularly pronounced. This indicates that the effects of forest management and tree mortality on dung beetles and subsequent changes in dung decomposition are mediated by directed shifts in mean forest structure rather than structural heterogeneity.
