If you are at AGU this week, please come to my talk on Monday 11:10 at MC 3007 (B12B-06). I will present using molecular composition of SOM to predict soil respiration.

Please also consider join us at session B31D and B33J on Wednesday. Looking forward to seeing you! #AGU23

NO2 exposure may increase the mortality rate of #SARSCoV2 , co pollutants of PM2.5 also have similar association

node degree (co-occur) was correlated with sequences% from sedim. So habitats determine the degree of co-occur. CCA shows sedim community is more related to environment (r2 = 0.53), including discharge, conduct, nuturients. Polynucleobacter is a strong urban indicator.

impervious cover% for both water and sedim. water and sedim grouped separately on PCoA plot. They also identified 312 indicator taxa for water, sedim, urban, forest. They also plotted co-occurrence network, where urban network is smaller and less connected than forest...

Increased expression of DNA repair and recombination genes, efflux pump genes (T6SS), biofilm formation genes (cell adhesion, virulence), also occurred. Similar response to exposure to antibiotics. They also simulated long term changes with more transformants.

#HGT #AMR This paper reported that non-antibiotic pharmaceuticals enhanced natural transformation of ARGs. 6 hrs exposures to 5 pharms at conc between 0.005 to 50 mg/L increased transformation frequency of A. baylyi by 2-3 fold, comparable to antibiotics

[Cheng Shi（师城） @mpchengsworld]

They suggested four mechanisms of increasing transformation by pharms. a) increased ROS production, b) increased membrane permeability, c) upregulation of universal stress and stress responses, d) increased expression of competence regulons and transformation genes.
