The Frequency, Magnitude, and Spatial Distribution of Heart Rot in Dominant Temperate Tree Species in a Forest Dynamics Plot.

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
The composition, dynamics, and health of forest tree communities are governed by interactions with the abiotic and biotic environment. Fungi are critical biotic interactors that play an increasingly appreciated role in forest tree health, particularly with respect to mycorrhizal and pathogenic fungi. Heart rot fungi, while known to infect a large fraction of the individuals in managed stands, have been considerably understudied in tree community ecology. Heart rot has been predicted to form hotspots in the forest due to crown or bole damage and/or soil moisture gradients and is expected to vary across species due to life-history differences. To address this knowledge gap, we quantified the incidence, magnitude, and spatial distribution of heart rot in 328 individual trees with diameters greater than or equal to 10 cm across the six most dominant tree species in a mixed broadleaf temperate forest dynamics plot. The results show that 71% of individuals display some degree of heart rot in this natural community. The incidence of heart rot did not significantly vary across species despite their life history strategy differences, but one species had a significantly higher magnitude of heart rot in infected individuals. Lastly, heart rot was spatially clustered across species, but heart rot incidence and magnitude were not related to soil moisture, indicating the importance of crown and bole breakage likely promoted by severe weather. The present study has conducted the first spatially explicit study of heart rot incidence and magnitude in a natural forest tree community. We demonstrate that over two-thirds of the large trees in the forest studied have some degree of heart rot indicating their widespread, but underappreciated, incidence in tree communities. We demonstrate that heart rot is nonrandomly distributed in this community and that spatial clustering of heart rot in forests is most likely due to hotspots of individual tree damage and not gradients in soil moisture.
