Weekend #Plankton #Factoid 🦠🦐
Research on how bacteria and archaea interact with other members of the plankton food-web is much more advanced in #ocean systems compared to freshwaters, but still very much unknown. They are food, but we also know of many cases of apparent symbiosis between #bacteria and organisms, with bacteria providing bioluminescence, energy via photosynthesis, or B vitamins, but how common is this? Read about the mission here. #science #ClimateChange
The plankton paradox: Unprecedented cooperationbetween bacteria in the Ocean
A team of CNRS researchers, led by Dr. Samuel Chaffron, developed a model based on data fromthe Tara Oceans expedition (2009-2013) to explain the plankton paradox: Ocean microorganismsof astonishing diversity should be competing, but instead collabor…deborah (Fondation Tara Océan)
#Copepod #zooplankton are the most numerous metazoans on the planet, and some have evolved into fantastical forms. Take Calocalanus pavo, the beautiful "peacock copepod", which has amazingly plumed antenna and caudal rami. It is small, ~1mm long, and uses the plumes to slow its sinking for feeding in the upper #ocean. It is famous for being very prominent in Ernst Haeckel's Kunstformen der Natur (1904) plate 54 #watercolour paintings of copepoda.

So sorry to hear that the quite wonderful Hakai Magazine will shut down at the end of the year.
A great privilege to read and even contribute to this excellent publication about science and societies on coasts around the world.

We know so little of the hidden world beneath the seas. This is a perfect example of why it is so risky to just power ahead and start mining our oceans.

Globally occurring pelagiphage infections create ribosome-deprived cells - Nature Communications
SAR11 bacteria and their phages are abundant in the oceans. Here the authors quantify the number of phage-infected SAR11 cells using microscopy techniques and discover phage-infected cells without any detectable ribosomes.Nature
So cool!

Daily turnover of active giant virus infection during algal blooms revealed by single-cell transcriptomics
"A consistent percent of infected coccolithophores displayed the early phase of viral replication for several consecutive days, indicating a daily turnover and continuous virocell-associated metabolite production, potentially affecting the surrounding microbiome"
Happy to share our latest paper, in which we examined the timing at which different microbial groups colonized the ocean!
The first author (Carolina Martinez) is starting her lab at UC Santa Barbara in 2024 and is looking to recruit postdocs and PhD students, so if this looks interesting to you, please reach out to her!

Kratosvirus quantuckense: the history and novelty of an algal bloom disrupting virus and a model for giant virus research
Since the discovery of the first “giant virus,” particular attention has been paid toward isolating and culturing these large DNA viruses through Acanthamoeba spp. bait systems.Frontiers
Marine #microorganisms are crucial for #ocean health.
#Bacteria, #archaea, #fungi, #algae and #viruses make up most of the biomass in the seas and form the base of marine food webs.
They support nutrient cycling and drive crucial biogeochemical processes, including key steps in the carbon, nitrogen and silicon cycles.
Ocean modelling must evolve to take their biological complexity into account.

Happy to share a collaborative preprint with Assaf Vardi's group in which we use single cell transcriptomics to link giant viruses with their native hosts during a marine algal bloom!
This approach is quite sensitive - we were able to identify viruses infecting one protist group that made up <0.5% of the community.

Viral infection in the ocean—A journey across scales
"Aquatic virology tackles some of the most challenging questions in microbial ecology and oceanography, trying to understand how microorganisms that are invisible to the naked eye can influence large-scale processes, such as biogeochemical cycles, or affect entire marine food webs."
