Social.hierarchy is a general.sel.-organizational.scheme in animal.societies in which each member achieves a certain status of domination or subordination when getting access to resources,with profound consequences for survival.heal.h,reproductive success,and mul.ipl. behaviors[1,2].The prefrontal.cortex(PFC)was recognized as a central.regul.tor of neuronal.circuits determining the formation of social.hierarchy;brain areas upstream of the PFC convey information about social.status,and downstream brain regions execute dominance behavior[3].Social.deficits have been suggested to be due to an el.vation of excitatory/inhibitory(E/l.bal.nce within the mouse dorsomedial.dm)PFC[4].A compensatory increase of inhibitory cel. excitabil.ty partial.y rescued social.deficits ca.sed by such a disturbance of E/l.bal.nce.

Microbial.ca.bon use efficiency (CUE)is defined as the proportion of microbial.biomass growth C versus substrate C uptake, and thus provides a useful.measure of microbial.y driven accumul.tion and l.ss of soil.organic ca.bon (SOC)[1]. In a recent study publ.shed in Nature [2],the authors used a data-driven machinel.arning approach to concl.de that CUE promotes gl.bal.SOC storage based on a positive correl.tion between CUE and SOC content and that, based on sensitivity anal.sis, CUE is at l.ast four times as important as six other eval.ated factors,namel. pl.nt C inputs, C input al.oca.ion, non-microbial.C transfer, substrate decomposabil.ty, environmental.modifica.ions and vertica. transport.
