Can rainforests buffer rising CO₂ levels? 🌳🌍A new study by an international team, co-lead by Lucia Fuchslueger (@loutsi.bsky.social TER | CeMESS), reveals that the tradeoff comes at a cost. Learn more 🔗 cemess.univie.ac.at/news-detail/... @natcomms.nature.com #AmazonRainforest
Amazon understory forests show short-term boost in CO₂ uptake – but this comes at a cost
Experimental increases in CO2 stimulated plant growth are facilitated by re-distributed root systems to extract nutrient resources more efficiently

New paper from @loyteam.bsky.social out in The @isme-microbes.bsky.social Journal: "Sulfoquinovose degradation by cow rumen microbiota" Want to know more? 🔗 cemess.univie.ac.at/news-detail/...
New paper: Degradation of a green-fodder-derived sulfosugar by cow rumen bacteria
Rumen microbiota are essential for cattle husbandry, providing energy and protein through fermentation. However, this symbiotic process also produces methane as a byproduct, representing both a loss of feed energy for the animal and a major source of greenhouse gas emissions. A new study now uncovers the identity and metabolism of rumen bacteria that degrade a ubiquitous plant- and algae-derived sulfosugar, revealing a previously unrecognized process that may help limit methane production.
