Using a cockroach model, researchers examined how complex microbiomes have built-in functional redundancies that enable them to provide community-level services despite changes in phylotype diversity due to environmental disturbances. #AppEnvMicro: asm.social/2hL
Phylotype loss has minimal impact on metabolic capacity due to pathway redundancy across phylotypes.

#MicrobiologyMonday: Marine sediments store vast amounts of carbon. By infecting and lysing microbes, viruses shape biogeochemical cycling from coastal zones to the deep sea and influence long-term carbon storage. Get the story in #AppEnvMicro: asm.social/2Qv
Diagram representing the impacts of viruses on aqueous sediment geochemistry. Organic matter (OM) sinks to the sediments, which is cycled in the microbial community, as well as increasing abundance, diversity, activity, and degradation of OM. From this “microbial loop” recalcitrant dissolved organic matter (RDOM) and dissolved inorganic carbon (DIC) are stored in sediments. Carbon is also released into the atmosphere from the sediment, and viral infection transfers genes between hosts or releases exogenous DNA to be used by bacteria, potentially aiding in metabolic activity.

In the face of climate change, temperature fluctuations profoundly affect animal physiology & health. Research shows that the gut microbiota, as critical bridge between the host & its environment, helps animals adapt to temperature changes. #AppEnvMicro: asm.social/30D
Schematic overview of microbial interventions for mitigating temperature stress in the gut. The diagram summarizes eight major strategies, including FMT, prebiotics, probiotics, synbiotics, postbiotics, nutritional interventions, phage therapy, and precision editing. Each strategy is paired with its core functional mechanisms, such as microbial reshaping, barrier repair, SCFAs enrichment, anti-inflammatory effects, and gut-brain axis regulation, illustrating how targeted microbial and nutritional approaches can restore intestinal homeostasis and enhance host resilience to thermal challenges.
