Top 5 Highlights of Deep Sea Exploration in 2017

What have this year’s deep sea exploration expeditions encountered so far? Read more to find out! Megan Chen I graduated with a Masters of Coastal & Marine Management from the University of Akureyri in Iceland, and am currently working at the Smithsonian Institution’s National Museum of Natural History in Ocean Education. I am interested in […]

Invasive seagrass changes fish community in the US Virgin Islands

Seagrass meadows provide food and habitat for a variety of fish species. Juvenile fish are particularly dependent on the meadows, for the shelter they provide from predators. In the Caribbean, several native seagrasses might be found in the same shallow estuary or coastline, forming a patchwork of meadows that support a variety of different fish […]

Seaweed antioxidants protect fish too

A new study suggests that feeding fish small amounts of antioxidant-rich seaweed can protected them from environmental challenges. Brittney G. Borowiec Brittney 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 metabolic responses of […]

Candidate compass genes in fish

A team of American researchers use next-generation sequencing to ask: “magnetoreception, how does it work?” Brittney G. Borowiec Brittney 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 metabolic responses of Fundulus killifish to […]

Sea lampreys: grow faster = grow male

A new study suggests that growth rate may determine if lampreys, an invasive fish in the Great Lakes becomes male or female. Read to find out more! Megan Chen I graduated with a Masters of Coastal & Marine Management from the University of Akureyri in Iceland, and am currently working at the Smithsonian Institution’s National […]

So cute!

It’s a trap! African penguins impacted by climate change

Young penguins living along the southwestern coast of Africa typically follow cool, nutrient rich water to find food as they grow up. This used to lead them to ‘delicious’ fish such as anchovies and sardines. However, in this ecosystem – the Benguela Upwelling Zone – climate change and overfishing have reduced these fish populations. This […]

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. Borowiec Brittney 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 […]

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 Flynn I am a graduate of the University of Notre […]

Pet trout: domestication rapidly alters gene expression

The impact of domestication can be detected within one generation in steelhead trout, and may involve adaptation to highly crowded conditions. Brittney G. Borowiec Brittney 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 […]

Rip Rap Sill: The Best of Both Worlds

The hybrid shoreline stabilization method called rip rap sill combines rock structures with native vegetation. This study found that fish biodiversity and abundance in rip rap sills was more similar to a native marsh than a built rip rap. Kari St.Laurent I received a Ph.D. in oceanography in 2014 from the Graduate School of Oceanography […]

Changing with the environment: how resilient are coral reef fish?

Coral reef fish are some of the most sensitive animals to climate change. How will coral reef fish respond to predicted increases in temperature and carbon dioxide? Do they have the ability to adapt to future conditions or is it already too late? Sean Anderson I am a first year MS candidate at the University […]

Small fish dine on small plastics and that’s a BIG problem

We’ve heard a lot about plastics in the ocean, but a new study shows the ecological implications of fish eating plastic. Here, researchers found that larval fish are preferentially consuming microplastics and it’s stunting their growth, altering their behavior, and increases death rates. Gordon Ober Postdoctoral Researcher, Claremont McKenna College I am currently a postdoc […]

Parenthood: The Most Rewarding Experience or The Ultimate Sacrifice?

Our human parents make a lot of sacrifices for us! They devote their time and energy, provide for us, invest in us (monetarily, sure, but also emotionally), nurture us, attempt to teach us, make career decisions with us in mind, and lose a lot of sleep worrying about us. However, in the marine world things […]

Fish – Animal Parents of the Year, 2016

When we think of parental care, fish aren’t usually the animals that jump to mind. But some fish do take care of their young – some species build and protect nests while others incubate their babies for extended periods of time. Learn all about these caring fish parents! Dina Navon I am a doctoral candidate […]

You look like your mom: parental effects in Atlantic salmon

In honour of our Mother’s Day theme week, we’ll look at how the environment experienced by parents during reproduction and their early life history influences their offspring. Brittney G. Borowiec Brittney is a PhD candidate at McMaster University in Hamilton, ON, Canada, and joined Oceanbites in September 2015. Her research focuses on the physiological mechanisms […]

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 […]

Oxygen favours the bold

It takes personality for the African sharptooth catfishes to breathe air. But they also consider their surroundings before visiting the surface. Photo: Wikimedia. Brittney G. Borowiec Brittney 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 […]

Disoriented fish are getting lost at sea!

Young fish rely on sound cues to navigate the vast ocean, but as our oceans acidify, the journey home to safely settle becomes much more difficult. Disoriented and slow, these fish are getting lost at sea Valeska Upham For my fisheries and aquatic science PhD I am working on how to tank raise urchins and […]

Rising above the noise

Oceanbites is still “ringing” in the New Year! Find out how in a sea full of noisy fish one can stand out from the crowd. And yes, fish can make noise! Gordon Ober Postdoctoral Researcher, Claremont McKenna College I am currently a postdoc at Keck Sciences, Claremont McKenna College. I work with Dr. Sarah Gilman, […]

Echoes in the deep: Robots with fish finders

You might call it the Batmobile of the sea: Scientists put sound based fish finders into an underwater robot to get closer to the creatures they want to study. Austen Blair Austen Blair is a MS candidate at the University of Rhode Island Graduate School of Oceanography. While his current research focuses on the influences […]
