Given that upland agricultural soils have been thought to marginally or do not contribute to atmospheric methane consumption due to the vulnerability of the high-affinity methanotrophs, our findings suggest a thorough revisiting of the contribution of agricultural soils, and the role of agricultural Our findings thus revealed an overlooked reservoir of high-affinity methane-oxidizers represented by the canonical methanotrophs in agriculture-impacted upland soils. The stable-isotope labelling approach allowed to attribute soil methane uptake to canonical methanotrophs, whereas these were not expected to consume (circum-)atmospheric methane. 16S rRNA and pmoA gene sequence analyses revealed that the as-yet-uncultured high-affinity methanotrophs were virtually absent in (PLFAs) were distinct in both soils, irrespective of amendments, and were unambiguously assigned almost exclusively to canonical alphaproteobacterial methanotrophs with cultured representatives. The 13C-enriched phospholipid fatty acids Soil methane uptake was sustained throughout the incubation (130 days), concomitant to the enrichment of 13C-CO2. Residue amendment transiently stimulated methane uptake rate (< 50 days). We performed a stable-isotope 13C-CH4 labelling incubation in the presence and absence of bio-based residues that were added to the soil to track the flow of methane. Here, we show that canonical methanotrophs can contribute to (circum-)atmospheric methane uptake in agricultural soils. Representatives have been detected along with the high-affinity ones, their role as a methane sink in upland soils remains enigmatic. Although the low-affinity canonical methanotrophs with cultured He’s just 1,325 points away from passing Kareem Abdul-Jabbar as the NBA’s all-time leading scorer, and the LeBron 20 could very well be a part of that moment.Aerobic oxidation of methane at (circum-)atmospheric concentrations (< 40 ppmv) has long been assumed to be catalyzed by the as-yet-uncultured high-affinity methanotrophs in well-aerated, non-wetland (upland) soils, the only known biological methane sink globally. It remains to be seen whether or not the Lakers will be able to re-tool and chase another championship this season, but there’s history on the horizon for James either way. The exact tech specs of the shoe haven’t been announced, but Complex has confirmed with sources that this is indeed James’ next signature model-not another Ambassador. It’s still built with the knit that’s become a staple in the LeBron line, the Swooshes are somewhat displaced and extend past the rear part of the shoe, and there’s no visible Max cushioning. With the LeBron 20, we’re getting a shoe that inarguably looks like an offspring of the Nike Kobe 4 and 5 era fused with the Kobe 9 and 10 Elite era. There’s more evidence supporting that theory with the on-court debut of the Nike LeBron 20. Perhaps part of the reason James continued going to the Ambassador 13 is that it’s a shoe that better suits his game, even at age 37. While the sig line typically features bulkier, high-tops with very visible Max Air cushioning, the Ambassador 13 is a bit dialed back-it’s a low-top that plays a bit more like a guard shoe with just Zoom Air cushioning. For a large part of the past two seasons, LeBron James has favored wearing his Nike Ambassador 13 sneaker over his signature models from the Nike LeBron line. ![]()
