Microbiology
Tough bugs below the waves?
Just as humans can build up tolerances to things we’re exposed to, so can bacteria. Introduce antibiotics to an ecosystem and it’s a fair bet local germs will take note. Tag along and learn what a group of scientists in Florida found after sampling the water we’ve flushed down the drains! Andrea SchlunkI am a […]
Think global, act local: how lake microbes respond to their environments
How do microbes in lake sediments respond to small and large scale influences, and what does it have to do with climate change? Nyla HusainI’m a PhD student at the University of Rhode Island Graduate School of Oceanography. I use models to study how small-scale physical processes at the air-sea interface – like waves – […]
Lights, Camera, and the Action-Packed World of Giant Viruses
A newly discovered giant virus might even be capable of altering its hosts ability to derive energy. A virus that infects a small eukaryotic predator has the largest viral genome found in oceans to date and has several novel genes that aid in its infection of these eukaryotic organisms. Samantha SettaI’m a PhD student in […]
Outreach- Ship to Shore STEM education
Delivering field work directly from the field to the classroom has become an important part of science communication and engagement. This post introduces a great learning tool called Adopt a Microbe- a fun and engaging project and website designed to bring microbes and marine science inside the classroom. Anne M. HartwellHello, welcome to Oceanbites! My […]
Microbialites are the unseen power house for marine and inland sea ecosystems
Ever hear someone say, “Just because you can’t see something, doesn’t mean it’s not there?” Well, microscopic bacteria and algae are hard to see, but they play an important role in marine ecosystems, and in some cases, many different types of bacteria and algae grow together and produce large reef-like structures. Read on to find […]
Fixin’ to lose: Trichodesmium reacts to climate change
Nitrogen is vital for all life on the planet. One of the main global sources for nitrogen, the bacteria Trichodesmium, may stop providing nitrogen to the global cycle in an ocean affected by climate change. LeAundra JeffsI am a Master’s Candidate at University of Delaware where I study the evolution of microbes in the sediments […]
Biofilms are a prominent first step in the colonization of wood-falls
A profound yet never-before-appreciated first step in the colonization of sulfur oxidizing bacteria on the surface of wood-debris in the deep-sea is attributed to sugars and other labile components of wood. Anne M. HartwellHello, welcome to Oceanbites! My name is Annie, I’m a marine research scientist who has been lucky to have had many roles […]
It’s getting cold in here!
As we here into winter, we notice changes taking place in nature all around us. But what do microbes in the ocean do when it gets cold??? Laura ZinkeI am a PhD student studying sediment geomicrobiology at the University of Southern California. My primary research interests lie deep under the sea studying how microorganisms survive […]
A blanket of oil: the role of bacteria in cleaning up after Deepwater Horizon
Nearly one million barrels of oil landed on the seafloor after the Deepwater Horizon spill – a feast if bacteria are able to consume it. Michael GrawI’m a 5th year PhD student at Oregon State University researching the microbial ecology of marine sediments – why do we find microbes where they are in the seafloor, […]
Riding the phage wave: Emerging role of viruses in the ocean
Viruses live in the ocean, where they infect bacteria who also live in the ocean. Ocean viruses are crucial to the ecosystem, but we don’t know very much about how they ‘survive’ in the ocean. Scientists used data from samples collected all over the world, and explored what types of viruses were in these samples. […]
The answer to starvation? Diversity
Photosynthetic microorganisms can’t go it alone, so they succeed by playing host to a diverse array of microbial partners Michael GrawI’m a 5th year PhD student at Oregon State University researching the microbial ecology of marine sediments – why do we find microbes where they are in the seafloor, and what are they doing there? […]
The ocean’s tiny, mysterious majority
The earth has more viruses than the universe has stars – but we know far less about our tiny majority at home than we do about the glowing balls of gas in our night sky. Michael GrawI’m a 5th year PhD student at Oregon State University researching the microbial ecology of marine sediments – why […]
Toxic living: finding the right home for sulfur-oxidizing bacteria
Hydrothermal vents are hot, dark, and toxic environments. But to sulfur oxidizing bacteria, they’re home. Michael GrawI’m a 5th year PhD student at Oregon State University researching the microbial ecology of marine sediments – why do we find microbes where they are in the seafloor, and what are they doing there? I spend my non-science […]
Methane on the dinner menu
Bacteria in coastal waters can eat methane, a greenhouse gas – but just how much and how fast can they eat? Michael GrawI’m a 5th year PhD student at Oregon State University researching the microbial ecology of marine sediments – why do we find microbes where they are in the seafloor, and what are they […]
Hunter-Chiller: Multiple feeding strategies for some of the world’s smallest organisms
Because of their ability to conduct photosynthesis, most of our planet’s oxygen comes from microscopic organisms in the ocean called algae. In addition to photosynthesis, some of these algae can also hunt and consume prey to supplement their energy needs. In this study a group of scientists has set out to determine just how their […]
Sharkcano, a melting pot for biology
No, a Sharkcano is not a volcano that erupts sharks. IT IS WAY COOLER THAN THAT! It is a submarine volcano that hosts a diverse macro community in water that is much warmer and more acidic that the surrounding seawater. Read more to find out about this alien-esc ecosystem in the South Pacific Ocean. Anne […]
A mercurial tug o’ war in Antarctic sea ice
DNA from bacteria living in Antarctic sea ice provides a clue to the mysterious origins of methyl mercury in seawater in the Southern Ocean. Abrahim El GamalAbrahim is a PhD student at Scripps Institution of Oceanography in San Diego where he studies marine chemical biology.
Lionfish slime helps ward off diseases
We know of many things that protect animals against disease – immune systems and gut bacteria are just the two most common examples. It turns out fish have antimicrobial properties that come from bacteria that live in the slime that covers their bodies, and it just might make lionfish specifically more resistant to disease. Erin […]
Speed dating: how finding that special symbiosis saved some coral from climate change
Choosing the right symbiont might be a coral’s ticket to cheating global warming. Abrahim El GamalAbrahim is a PhD student at Scripps Institution of Oceanography in San Diego where he studies marine chemical biology.
Wasting Away in Virus-ville
Sea star wasting disease still plagues the U.S. West Coast, but clues to its nature are being uncovered. Find out how temperature may be a key player in the progression of the disease in today’s article!
