Shifts in bacterial traits under chronic nitrogen deposition align with soil processes in arbuscular, but not ectomycorrhizal‐associated trees
Chronic nitrogen (N) deposition reduced carbon (C) and N uptake across bacterial taxa in arbuscular (AM) and ectomycorrhizal-dominated forests (ECM). Reductions in C and N uptake occurred more homoge....

![The dataset contains nine 0s and one 1. One approach is to nudge our 0s towards .01 and our 1s to .99, or apply a special formula (Smithson & Verkuilen, 2006) so values fall within the [0, 1] interval. We implore readers not to engage in this practice. Kubinec (2022) showed that this practice can result in serious distortion of the outcome as the sample size grows larger, resulting in ever smaller values that are “nudged”. Because the Beta distribution is a non-linear model of the outcome, values that are very close to the boundary, such as 0.00001 or 0.99999, will be highly influential outliers.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:c4uwzyiy4la35kq35rsft35z/bafkreiexktzh3l7ae7ynwlnlwlozadmhm7c4ptu7fyu7jk6y3p5q45pw5e@jpeg)
