I don’t know where this came from but my kid mentioned a teacher hiding the word “Madagascar “ in white font within an assignment. Anyone who had that word in what they submitted failed the assignment bc they clearly used AI.

Unfortunately, in our latest work, we estimated an 8-fold increase in bacterial diversity for smoke with a hazardous AQI rating (PM2.5 >225 ug/m-3). #bioaerosol #smoke #microbiome doi.org/10.1186/s424...

The ecology of a smoke plume: bioaerosol patterns reveal abiotic and biotic drivers of diversity - Fire Ecology

Background Wildland fire is known to play an important role in aerosolizing microbes sourced from vegetation and soil communities, but little is known about their spatiotemporal patterns across environmental gradients in smoke plumes. During prescribed fires in Kansas tallgrass prairies, simultaneous deployment of three uncrewed aerial vehicles (UAVs) equipped with bioaerosol sampling and environmental sensor payloads enabled simultaneous measurements (~100 m intervals) across smoke plumes to better understand patterns of aerosolized microbes, relationships to their environment and sources, and their transport. Using data collected from nine smoke plume transects, we made comparisons to samples collected from ambient air to evaluate hypotheses about microbial composition and diversity as the smoke advected with prevailing winds. Results As distance from the flaming front increased, our data indicated changes in the composition of smoke-borne microbial assemblages that correlate to plume environmental gradients. The detectable contribution of terrestrial communities as sources of smoke bioaerosols decreased with deposition, smoke aging, and dilution with background air. Microbial composition of the smoke also differed based on the historical fire regimes of the burn units compared. Our results also demonstrate that “hazardous” Air Quality Index levels, based on particulate matter concentrations, corresponded to a fourfold increase in bacterial taxa richness, relating a novel microbial component to the metric most widely used to communicate with the public about smoke hazards. Conclusions Grassland fires demonstrated an attenuated smoke signal as smoke aged, traveled, and diffused, but across the ~300 m distance measured, the plume and its biological assemblage remained distinct from background air. Smoke assemblages were driven by fluctuation in relative humidity (RH), particulate matter (PM) concentration, and differences among the vegetation and soils of the source communities as influenced by historical fire frequency in the tallgrass prairie sites. The distinction between smoke and background air microbial composition and diversity was not as pronounced as in previous studies of higher intensity fires consuming greater fuel loads, yet richness and diversity increased with deteriorating air quality indices. This relationship shows that fire behavior producing more PM emits and transports a wider variety of terrestrial microbes from tallgrass prairies.

Seriously! 😷 We know SO many terrible impacts of smoke exposure. And, we haven’t even started looking at the health consequences of microbes in smoke. It’s alive. www.wnycstudios.org/story/9d5209...

Emily Barker was a remarkable person who brought joy to everyone around her. Her sudden passing while fighting wildfires has left her family devastated. This fundraiser aims to support them during this incredibly tough time. If you can, consider donating/ sharing this post. Every little bit counts.

We will soon be advertising a 3-year postdoctoral position at Bristol aimed at enhancing our modelling capacity to better characterise vegetation recovery & legacy effects following fire. Please keep us in mind if this is your speciality 😀 🔥🌳 🌱

Do any of you have an AI policy document for your lab group clearly stating expectations regarding student / postdoc use of LLMs in background research, coding, writing, reviewing, etc? I'd be interested in a model as we develop one.

Hi #microbiomesky and #mevosky and also #phagesky maybe? Some of us want a microbiome journal club to catch up on microbiology/evolution related microbiome research. Monthly@15:00 CET/09:00 EST/18:30 IST or so Please text my LMU email address if you're interested (not typing it here to avoid spam)

Does anyone know of an online microbiome journal club? I'm interested in joining one. More along the lines of evolution and microbiology than immunology or human effects #mevosky #microbiomesky

“As the annual Pride parade weaved its way through Durham… the rainbow flags were almost matched in number by trade union banners, as miners, postal workers, and train drivers swelled the parade’s ranks in solidarity, making it the biggest in Durham Pride’s history.” Solidarity is our strength. 🏳️‍🌈🏳️‍⚧️

ICYMI: Application review starts July 1, so there's plenty of time. We have up to three years of funding for a really cool project. The team includes folks at UVM, Bennington College, and the University of Hawaii. If you love mountains and plants, check it out! Please share with your networks.

I'm hiring a postdoc to lead sedimentary aDNA reconstructions of alpine plant biodiversity as part of a broader project exploring the mechanisms of alpine plant resilience. Come join a collaborative team working in beautiful places! Bonus: postdocs at UMaine are unionized!
