This is an erratum to the paper 'Discovery of a mid-infrared protostellar outburst of exceptional amplitude' (2020, MNRAS, 499, 1805 1822). Upon the original publication of this article, several concluding results were inadvertently omitted, making several points in the article unresolved. The publisher apologises for and has since corrected this error online.

Microbial communities are found throughout the biosphere, from human guts to glaciers, from soil to activated sludge. Understanding the statistical properties of such diverse communities can pave the way to elucidate the common mechanisms ...Multiple ecological forces act together to shape the composition of microbial communities. Phyloecology approaches—which combine phylogenetic relationships between species with community ecology—have the potential to disentangle such forces but are often ...

After the publication of the original paper of Klement et al. (2015), a software bug was found in the radiative transfer code HDUST version 2.02. The error in the code regarded the precise nature of the photon launching mechanism at the stellar surface and resulted in slight underestimation of the mean intensities in the equatorial region, with small but detectable e-ects in the disk temperature and emergent spectrum. The new, corrected version (HDUST 2.10) causes the computed temperature to be slightly lower and the level populations more neutral. The changes in the resulting synthetic observables were found to be mostly minor: a decrease in the level of polarization, line emission, and the IR flux levels. The e-ects of the software bug get larger with increasing stellar rotational velocity. In the specific case of CMi, which was found to rotate very close to or even at the critical velocity, the changes in the computed spectrum required revisiting of the original modeling procedure. The changes to the model and how the revisited model reproduces the observations was fully described by Klement et al. (2017a). The results regarding individual observables after the code update can be summarized as follows: - Spectral energy distribution (SED). The full SED is now fully reproduced using a single power-law (with n = 2:9) prescription for the disk density (Fig. 1 of Klement et al. 2017a). The conclusion that the outer disk is found to be truncated at the distance of 35 stellar radii remains unchanged. - Hydrogen spectral lines. All four modeled emission lines - HγHβ Hγ and Br - are now reasonably well and simultaneously reproduced by a single model (Fig. 2 of Klement et al. 2017a). y Deceased. - The linear polarization. The observed polarization percentage is now reproduced within the error bars by the same model mentioned in the previous two points (Fig. 3 of Klement et al. 2017a). - Interferometric observables. The fit of the new model to the interferometric observations mostly shows a slight increase in the quality of the fit with the exception of the AMBER spectro-interferometry, for which the resulting reduced-2 increased from 1.20 to 1.52 (Table 1 of Klement et al. 2017a). To conclude, the update of the radiative transfer code HDUST resulted in the improvement of the overall agreement between the viscous decretion disk (VDD) model predictions and the multitechnique observations of CMi. All of the observations were simultaneously reproduced using a truncated VDD with a single power-law prescription for density. This replaces the original conclusion that there is a dual behavior in the disk density profile, with the very inner parts requiring a steeper fall-o-in density than the more extended parts. No physical explanation was originally found for this feature and it turns out to have been the e-ect of the code error. As for the structure of the outer disk and its truncation, the conclusion remains the same as that in the original paper. The outer disk structure was revisited by Klement et al. (2017b) using additional radio data.
