In 2022, the #NSF Advanced Studies Institute on #WaterQuality & #HarmfulAlgalBlooms in Lake Victoria, Kenya conducted a three-week survey of the Nyanza Gulf. This week, a subset of the original team went back to follow up on our initial findings - a thread 🦠🇰🇪

Congratulations to Margarita Lankford on a successful thesis - and thank you for inviting me to be on your committee! My first of hopefully many…committees & phytoplankton themed cakes that is 🦠🌊

Sunday sampling trip to the Albemarle Sound & Chowan River of North Carolina. Cyanobacteria were abound, particularly in the Chowan as we were hoping! More to come once we extract all these sterivex in the -80 C…

OK. So you get a motivated postdoc @zepernickbn.bsky.social, who teaches a class of great graduate students, and then some support from the institution and a lot of great labs. Find yourself a nice pink algal bloom in the early spring and....science happens.

The ornithine-arginine cycle supported a toxic, metalimnic Planktothrix rubescens bloom
Planktothrix rubescens is distinct from other cyanobacterial harmful algal bloom (cHAB) genera: the crimson-red cHAB thrives in the cold, low-light, nutrient-limited metalimnion. Studies have attribut...

The first contribution from David Niknejad's thesis: a collaboration with UTIA and the Watershed Association of the Tellico Reservoir to start applying molecular tools to the Tellico Reservoir. Thanks to USC's @eric-a-webb.bsky.social for jumping in to help!

A great defense of discovery-based science in a time when it is very much needed.
“Why Are We Funding This?”
Long-standing myths about “silly science” have contributed to the reckless slashing of government-supported research.

That’s a wrap on the #OceanObservatoriesInitiative #ImagingFlowCytobot Community Focus Group at UNCW! Looking forward to using this data in the lab and the classroom 🌊

Many phytoplankton are affected by climate change via changes in temperature & pH, but to winter diatoms, it appears the issue is light.

Had an amazing time at #Eco-DAS2025 here in Oahu, Hawai’i! Much scientific scheming was had & new collaborations were made - stay tuned for the pubs to come from the phytoplankton ‘omics team with @akrinos.bsky.social & others!

Gordon Research Conference in Polar Marine Science 2025 was a success! Had a great time discussing all things related to sea ice & proton-pumping rhodopsins, and made new friends along the way. Looking forward to the next one!

NOAA's #GreatLakes Environmental Research Lab will be taking an "indefinite hiatus" from communications due to staff cuts. GLERL communicates critical weekly updates about the extent of harmful algal blooms in Lake Erie - like the one that left my hometown of Toledo without drinking water in 2014

Monthly Albemarle sampling in 45 mph wind gusts! 🌊 Lots of sand mixed in with the plankton - going to be a challenge to extract. Peep my technician & the truck “lab”.

Happy to see "Lysogen formation governs colonies while lytic infection is more prevalent in single cells of the bloom-forming cyanobacterium, Microcystis" available.. Xuhui and others show a linkage between lifestyle (colonies vs single cells) and infection strategy (lytic vs lysogenic)
Lysogen formation governs colonies while lytic infection is more prevalent in single cells of the bloom-forming cyanobacterium, Microcystis
While the bloom-forming cyanobacterium Microcystis can exist as free-living single cells or within dense mucilaginous colonies, the drivers and consequences of colony formation remain unclear. Here, w...

Great write-up on our work in Lake Victoria, Kenya by my partner-in-crime @laurenhart.bsky.social & colleagues! Check it out to see how the North American & African Great Lakes share a few commonalities - including toxigenic cyanobacteria 🧪
Lake Victoria is turning green – the deadly bacteria behind it
The organisms that cause greening are highly concentrated in Kenya’s shallow Winam Gulf.

A brisk, foggy day on the Neuse River, NC with the Paerl lab ModMon team. This month’s run we encountered a bloom - 160 ug/L Chlorophyll a readings & some very yellow-brownish filters! 😊
