“…Contrary to the proposed hypothesis of element homeostasis, we observed high flexibility in fungal C:P and even C:N ratios, reaching values far beyond common estimates of microbial stoichiometry (Cleveland and Liptzin, 2007; Strickland and Rousk, 2010), with maxima of 1488 and 126, respectively. Induced N and P limitations under controlled conditions reduced the relative amount of fungal N and P concentrations on average by 69 and 81%, respectively, causing wide fungal C:nutrient ratios, while increasing C availability in more natural substrate (i.e.…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…sequestration). These findings are also consistent with previous studies that the decomposition of different substrates is regulated by different microbial populations [ 83 , 84 ]. The variable responses of microbes to warming could be due to differences in the physical and chemical properties between aggregates, which affect the availability of different substrates and the composition of microbial communities [ 54 , 85 ].…”
