community ecology
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 […]
Melting ice, shifting microbes
Polar bears have been the poster child for sea ice melting in the Arctic. But what does sea ice loss melt mean for the Arctic’s most numerous members – its microbes? Michael GrawI’m a 5th year PhD student at Oregon State University researching the microbial ecology of marine sediments – why do we find microbes […]
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, […]
Aliens in the kelp forests – community ecology and Miso soup
In the plant world, competition between species is almost always over space. Space dictates how much sunlight, nutrients, and potential mates you have access to. In community ecology, it’s thought that ecosystems only have so much space to offer different species, with some ecosystems containing more space than others. Most systems are also thought to be saturated so that, […]
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? […]
Stressed-out microbes in an acidifying ocean
The ocean is acidifying in response to carbon dioxide emissions, but we are just beginning to learn how this effects the ocean’s most abundant lifeforms – microbes. 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 […]
Vacancy at your local kelp forest
A diverse community of seaweeds, snails, sponges, crustaceans, and more, find refuge and food within the dynamic kelp ecosystem. Katherine BarrettKate is a 3rd year PhD candidate in the Biological Sciences Department at the University of Notre Dame, and holds a Masters in Environmental Science & Biology from SUNY Brockport. She studies benthic-pelagic ecosystem linkages […]
Now we got bad blood: Oxygen binding is not affected by haemoglobin subtype in Atlantic cod
Why do northern and southern populations of Atlantic cod have different haemoglobin subtypes? A recent study upsets over 50 years of theory. Brittney G. BorowiecBrittney is a PhD candidate at McMaster University in Hamilton, ON, Canada, and joined Oceanbites in September 2015. Her research focuses on the physiological mechanisms and evolution of the respiratory and […]
Small MPAs: the new all-you-can-eat buffets?
Marine Protected Areas (MPAs) are a popular conservation tool and are in many situations very effective. Unfortunately, as with many plans, there may be some unintended consequences, as seen in the case of small MPAs in Fiji, where they appear to have attracted corallivorous crown-of-thorns sea stars (Acanthaster spp.). Find out more in today’s oceanbites! […]
Hard Coral or Macroalgae? Coral Reefs May Have Another Option
Most of the time coral reef communities are discussed, it seems the focus is whether they’re dominated by hard coral or algae. It turns out there may be other possible outcomes for reefs in the future. Find out more in today’s oceanbites! Rebecca FlynnI am a graduate of the University of Notre Dame (B.S.) and […]
Mangrove Takeover Impacting Salt Marshes
Mangroves are encroaching on salt marsh habitats worldwide, but what does this change in plant community mean for the plants, ecosystem processes, and other inhabitants of these areas? Find out a bit of the answer to that question in today’s oceanbites! Rebecca FlynnI am a graduate of the University of Notre Dame (B.S.) and the […]
Grunts and Gnathiids: One Fish’s Daily Migration to Escape Parasites?
Animals move for a number of reasons. The French grunt leaves the coral reefs at night for seagrass. A group of scientists proposes and provides good evidence for why they might do that! Read on to discover whether they’re leaving to avoid being parasitized? Rebecca FlynnI am a graduate of the University of Notre Dame […]
Seagrass Invasion! Tunicates colonizing seagrass beds impact plant and animal community
Seagrass habitats worldwide are in decline due to a number of factors. What happens when an invasive species comes on the scene to add to the stressors affecting seagrasses? Rebecca FlynnI am a graduate of the University of Notre Dame (B.S.) and the University of Rhode Island (M.S.). I now work in southwest Florida, contributing […]
The importance of sea urchins
A look into Valeska’s graduate research. Why coral reefs depend on the long spined black sea urchin for survival. Valeska UphamFor my fisheries and aquatic science PhD I am working on how to tank raise urchins and transplant them onto reefs across the Florida Keys in order to help reverse the phase shift from algae […]
Fooled Ya! How marine animals stay hidden in plain sight
It’s April Fools’ Day! Today’s the day when you try to prank people, convince them your lies are true, and generally make mischief and act sneakily! Animals have to act like it’s April Fools’ Day everyday, and it probably isn’t nearly as much fun since their lives depend on it. Predators sneak up on their […]
Are satellite tags the new dinner bell for harbor seals?
Satellite tags are being used to study the foraging behavior of fishes, but in the lab harbor seals have been found to be attracted to the acoustical signal given out by these tags. In the wild, does that mean these tags are acting as a dinner bell for harbor seals? Valeska UphamFor my fisheries and […]
Predator vs. Prey: starfish vs. coral
The crown-of-thorns starfish has become a vicious predator of acroporid corals in the Indo-Pacific. This study looks at recruitment strategies of both the coral and the starfish in order to better understand if the coral has a chance of surviving the feeding frenzy of the crown-of-thorns starfish. Valeska UphamFor my fisheries and aquatic science PhD […]
Comparing all the ecosystems ever reveals cool patterns about their structure
Who’d guess that if you took the data from >2000 ecosystem studies and smashed them all together there’d be some interesting information in there somewhere? It turns out general relationships between individuals’ size and metabolism are reflected on the ecosystem level as well, across a huge span of marine and terrestrial life. caelCael was once […]
Better Together: Mutualisms contribute to reef fish recruitment
All other things being equal, would you rather live where mutually beneficial relationships are available or where they aren’t? Well, if you’re like me, you’d prefer beneficial relationships. And I’m not alone in that. It turns out that damselfish on reefs prefer to settle where there are cleaner wrasses to keep them parasite-free. Read on […]
I’ll stand guard for you!
When it comes to helping each other out, it turns out that some fishes are better at it than we thought. New research shows how when foraging for food some rabbitfish species stand guard for one another, demonstrating how fishes can posses the cognitive ability to carry out reciprocal altruism acts. Valeska UphamFor my fisheries […]
